Heat Tech Services Limited

I have used Mark and Heat Teach Service Ltd every year since 2006 for my boiler service, central heating replacement, and other plumbing needs. Everyone is always polite and professional respecting my property and my personal circumstances. Excellent and quality service, who I trust.

Had suspicious smell of gas. I decided to phone Mark Ockenden of Heat Tech Services as his firm are registered Gas Safe Engineers. I have used their services for Gas boiler installation, maintenance and general plumbing for many years. I have found his staff, well qualified and highly effecient. Mark arrived on time. He tested for a leak and determined it was minor but needed to be attended to. He found the leaking valve, which was embedded in my fireplace surround. To avoid damaging the fireplace, he lifted carpet and adjacent floorboard, cut the pipe and capped it with a soldered repair - all with my agreement. He put everything back in place and it looks just as it was before the repair was carried out. As usual - excellent service.

Mark diagnosed the problem over the phone, arrived promptly and brought all the necessary materials. Did the work to a high standard and gave helpful explanations and advice. Highly recommend him.

The work was carried out in a professional manner, on time and by a very helpful team. Would highly recommend.

We have used Mark for some years before at another house to install a new boiler, annual servicing and various heating issues. Mark always responds very quickly and this time our boiler developed a fault and stopped working. Mark diagnosed the issue, discussed with us what was needed, and then ordered the parts required . The work was completed very promptly to get the boiler working and also completed servicing of our Vaillant boiler and mega flow. Mark is very knowledgeable and helpful and completed the work to a high standard. I will certainly continue to use Heat Tech in the future .

I was recommended the company by my sister and they did not disappoint. Clean, tidy, knowledgeable and helpful. Bolier service completed and the shower problem that I had misdiagnosed was found and suitable suggestions forwarded to me to decide on.

I have used HeatTech since 2006. Always had professional excellent customer service from Mark and his staff. On Friday my boiler broke down. Within a few hours Mark was around at my property sorting the problem out and replacing the pump. As ever excellent service at a reasonable price, with fast time response which I am so grateful for. I will be using HeatTech again.

Came promptly and carried out a thorough service on our old back boiler where other firms have declined to do the work as they no longer service this type of system. Very pleased with the work carried out and the advice given, will definitely recommend.

I called Mark around 6 pm Friday as my normal plumber was booked and I had not had hot water for a week despite my boiler apparently firing up. Mark asked for pictures of my set up and then called me back to use telephone triage with very easy guidance on things I needed to check which quickly led to an over the phone diagnosis of the problem (a failed valve); Mark clearly explained his pricing which was extremely reasonable and committed to come this morning (Saturday 9 am); he quickly confirmed it was a valve problem replaced it and explained how I could run my system more efficiently . Hot water worked perfectly after a few minutes. I recommend Mark very highly and will now use him/ Heat tech for all my boiler servicing work as I was so impressed.

We have used HeatTech for a number of years now as they got us "out of hole" when British Gas said just before Christmas that they couldn't come for 10 days despite the fact that we had a contract with them. Mark and his team fitted us in at short notice and fixed the problem so that we were warm over Christmas. We have continued to use HeatTech and are extremely satisfied with their service.

Customer service and attitude of some of the plumbers a little unfriendly But the work done was good … Until I had a problem weeks later in the same room in a different place Was charged over £100 for the leak to be looked at And the problem was not fixed I was told I was abusive when I questioned the price … And my professionalism questioned … Quick to respond and work ok But not great if you want to complain

Mark was incredible knowledgable and thorough when he visited us and went through in detail our old system with two boilers over 3 floors. He checked and double checked how it all worked and how to improve our system with a new boiler. The quote arrived quickly and dates booked in. Sapphire, the chef engineer plus 3 other engineers, arrived on time and with respect to our home, took everything out and replaced the new system , looks like a pice of art now and not spaghetti junction!. Nothing was a problem, any queries checked and resolved. I highly recommend if you want a water/ gas related job, large or small, then use Heat Tech. Best decision I have made this year about who to replace our boiler with. Great Team Mark, thank you for sorting out a long time problem. Erica

You cannot ask more from a contractor than they are prompt, easy to deal with, turn up on time and then they diagnose and swiftly fix problems.

Second time using Heat Tech and again excellent service. My elderly mum had no hot water but Mark diagnosed where the problem was, over the phone. Amazingly they were able to come out the same day and had the problem fixed within twenty minutes. They were very clear explaining what the problem was, which impressed my mum, as she has dementia and often struggles to understand people. Can’t rate them highly enough.

Rang the office in the morning and they had just had a cancellation so van arrived 20 minutes later and installed new tap within half an hour. Very happy customer !

Used Heat tech for the first time and they were able to fit us in on the same day. The engineer (Saphire) immediately understood what was needed and the whole job was done in half a day. As a result the water pressure from the mega flow doubled. We have lived here for 15 years and never had the pressure so good. Definitely will use them again.

We have been using Heat Tech for a number of years for plumbing and heating and cannot praise them enough. Mark has built a fantastic team and we have never been let down. Mark always puts himself out if we have anything urgent and his prices are usually very reasonable. We wouldn’t hesitate recommending Heat Tech to anyone that needs plumbing or heating services. Thanks Mark and team!

Replied promptly. Arrived on time. Helpful and personable engineers. Diagnosis and repair completed efficiently. Will use again for our boiler service.

They diagnosed the problem and fixed my boiler pump on the same day that I telephoned them. Workman was pleasant to deal with. Very happy with both the service and the work completed.

I called Mark at Heat tech on Tuesday 13th, he arranged for George to come on Wednesday 14th. They arrived, as promised, at 8:30 am, the work was carried out within a couple of hours. They were so tidy and polite, the workspace was left clean and tidy after having two radiators removed from both sides of a wall. collateral damaged done to the floor in the dining room which was okay as floor is coming up anyway, but I was kept informed at all times as to what had to happen. The next good surprise was the invoice I received, very pleasantly surprised at the charge for the job. I was recommended Heat Tech by a neighbour and am so glad she did, any plumbing jobs I need doing in the future will be with Heat tech, and yes I will definately be recommending them to others in the future. Thank you again gentlemen for your stirling work

HeatTech are known on the Estate I live in and I had already had a recommendation. The work I needed doing was a new shower unit in my walk-in shower, a new kitchen tap with added water filter and a new cistern valve in one of the other bathrooms. The hardest part of the work for Sapphire, who did the shower was having to remove tiles in order to get the piping out without upsetting the other bathrooms using a power showers. Fortunately I had some tiles left from the original job about 30 years ago. She grouted those tiles really well and no-one would know anything had changed, except me, of course! Sapphire had two young helpers for the other two jobs. I am extremely happy with their approach to the work and the efficient and friendly manner in which it was done and would certainly recommend HeatTech. Helen Dean

Our hot water system was on the blink. HeatTech carried out a very detailed investigation, very promptly. It was a very frustrating and intermittent problem. They made several visits and in the end we decided that the boiler was really past help. They installed a new boiler very quickly indeed. Throughout the process they always responded to queries/texts from us very speedily, even out of hours. We have used HeatTech for many years and would thoroughly recommend them

Excellent service and response from this local plumber. 100% recommended for any plumbing, central heating and boiler repairs

I phoned Mark and he sent an engineer George round the same morning. The pump on our heating system was replaced. We are still working through other issues on an old heating system.

We have used this company for a few years now for boiler and water tank service. Ethan attended twice this month regarding a minor leak. We were impressed and are always pleased with the team generally, very prompt and reliable.

Used Heat Tec over Christmas period as heating was not working. Engineer (Dave) came out on 27 Dec., changed motor. However, problem soon returned, and he made 2 more visits, very promptly after my call. Diagnosed and sorted an elusive fault on 6 Jan. All is in perfect order. Very pleasant, ever ready to help, any time. Fair and reasonable cost. Call handlers also extremely patient and polite. Will be our regular service engineers in future.

I’ve used HeatTech before and they’ve always been excellent. This time one of my heating pumps (not installed by them) sprang a leak and we had to shut the whole system down. HeatTech got someone here within a couple of hours of my call, and did their usual highly professional job of fixing the problem and replacing the damaged components. Highly recommended.

Heat Tech was a recommendation, and I am happy to pass this on. Very professional and reliable from end to end. Knowledgeable, friendly, tidy and efficient. Work was completed to a high standard and the team kept me fully informed along the way. Even though I have a full British Gas home care agreement my experience with Heat Tech surpassed BG in every area. HT are competitively priced so paying separately for work that could have been carried out by BG was a no brainer, they were in and out quickly and knew what they were doing. Very reassuring. I have no hesitation in recommending and HT will become a trusted trader I know I can and will call upon again.

I have used Heattech since 2007 for my central heating and pumbling needs. As ever excellent professional work. Eveything always explained to me. Heattech undertstands my needs and respct that. Pofessional staff always arrive ontime, who respect my home. They are kind and engaging. Good value for money.

I’ve used Heat Tech a number of times and I’m happy to say that they are more than willing to prioritise urgent work and have done an excellent job for me. I switched from having a service contract with a large nationwide company to using a local firm who are both quicker and more conscientious, not to mention cheaper.

I highly recommend Heat Tech. They booked us in for service within a good timeframe. The engineers were on time and did a thorough service.

Fast, friendly efficient service. Problematic leak that was causing a problem, Heat Tech prioritised it and got it sorted quickly. Highly recommended.

I have used Heat Tech since 2006. Professional friendly local company. I am always pleased and satisfied with the service I have received. Arrive on time, if not earlier than the appointed time. Understand my needs and respects that. Competitively priced. I will use them again.

Had the boiler serviced by Heat tech in September. £120 is at the expensive end for this but figured was best to pay up for a quality service to avoid unwanted expensive failures during the winter. Boiler (combi) had been working fine before the service, but almost straight away post service we started to have instances of needing to re-pressurise the system. This happened a few times so eventually called Heat Tech back in a month later to investigate, where they found a fault with the expansion vessel, despite having signed this off as working fine at the service the previous month. £265 bill to find the fault, order the part and return to replace it. Spoke on the phone, Heat Tech not interested in excepting any liability or goodwill gesture for the sequence of events or questions around the service quality. Will not be using them again.

After contacting Heat Tech about fixing our boiler, they were great from start to finish. Sapphire was very friendly and helpful, doing the best she could to fix the fault and went out of her way to come back later that day to sort it. Reasonably priced and very reliable - would highly recommend!

We use this company for our regular boiler service and also for other projects such as fitting a heated towel rail. We feel confident we are getting good work done for a fair price and the company is good to deal with.

Mark has been me go to plumber for about 5 Years. The following work was carried out to my complete satisfaction. Service Boiler. Replace leaking radiator. Replace plastics pipe work with copper to the central heating pressure vessel. 5 Star work from a 5 Star company. What more can you say.

Central heating was intermittent and not responding to the thermostat. After having a couple of locally recommended engineers look at the system and fail to properly diagnose the fault I came across this Which site which contained many satisfying reviews. Talking to Mark on the phone it was very clear that he was the engineer I was looking for. As a retired engineer of 60 years in electronics development I found we could discuss my problem successfully. Heat-Tech engineer George, came over to checkout the system and found it not to be wired according to published standards and recommended that rewiring was needed to enable efficient fault finding. Subsequently he got the heating working but there were occasional fault modes occurring and a new electronics board was needed. After fitting a replacement board the system is now working correctly. Costs of labour and parts were good value and I would call them again if required. I'm pleased with the fast and competent service from the company and would recommend Heat-Tech as a first choice. Thank you Mark and George.

Mark is responsive, honest and very experienced. His team are equally commendable and it was a pleasure to have them working on our heating system.

Mark rected very quickly to the urgent need for a water heater used by the local Infant School. The work was carried at on time and most professionally

We have used Heat Tech several times over the past few years to fix emergency issues with our heating. Always extremely reliable, efficient and pleasant to deal with. This time it was a planned visit for a boiler service. 100% delivered as anticipated.

Arrived home from trip with water leaking into Garage. Called Heat Tech at 5PM and they arrived 9AM following morning to fix the leak. Very efficient and extremely professional. We have been using Heat Tech for many years as they stand out from other contractors we have used in the past.

We chose Heat Tech Services Ltd from a Which plumber search. Called the company, explained our requirements. Received a very prompt response where the guys completed an excellent job the next day. Clean, tidy and very efficient. Highly recommend 👌

Having tried every trick possible, I decided it was time to call in an expert. Called first thing on Monday morning and got an appointment for the same day. The guys turned up on time and within minutes the toilet was unblocked. No fuss. No mess. Professional and efficient is how I would describe the service. I can honestly say it was a pleasure to do business with Heat Tech and I would definitely recommend calling them for your plumbing problems. Additionally, I was pleasantly surprised that the bill was less than the estimate quoted. Many thanks!

Neil & Lewis came to service our boiler, megaflow and central heating system. All looking good. Nice guys too!

I have used Heat Tech for many years and now have had some radiators changed this week. The whole process was straightforward with a preliminary visit and quote through to the work being done on time and for a fair price. Every member of the team has been professional and competent. I highly recommend Mark and his team.

Called on a Saturday and had a quick response and appointment for Monday morning. Washing machine valve replaced. Polite and good service. Would use again for any plumbing jobs.

I have a boiling water tap in my kitchen which is 3 years old, but it suddenly started to leak by the tank under the sink and so I needed a plumber fairly quickly. My usual plumber is good but incredibly hard to contact and never available at short notice, however, I left a message for him to call me early that morning. I spoke to a local friend about this problem that same morning and she recommended Mark to me. When I had heard nothing from my plumber by lunchtime I decided to call Mark and he answered the telephone quickly. We had a discussion about the problem which resulted in me sending pictures by WhatsApp to him. He then called me back quickly and diagnosed the problem. The following day two plumbers appeared and they worked hard to solve the problem, but alas specialist spare parts were required from the manufacturer. Off his own bat, Mark spoke to the manufacturer and managed to secure a brand new replacement tap under the warranty. The new tap was couriered to me quickly and Mark sent the same two plumbers back to instal it. All done with a minimum of fuss or hassle. To be honest I was very impressed with Mark's no nonsense approach to jobs and the initiative he showed in going direct to the manufacturer without bothering me.

Mark was recommended on local WhatsApp group and now I know why. Efficient, timely and reasonably priced and tidied up afterwards. Couldn't have asked for more and would highly recommend!

I received a recommendation for this company, and used them for the first time to replace a faulty heating timer and a boiler service. The engineers did what they said they were going to do, when they said they were going to do it for a reasonable price. I am happy to recommend them without any reservations.

Brilliant. We had no water. We called Mark. Within 2 hours he sent a lady plumber and her assistant. She found the problem, went out to buy a spare part, returned, and all was completed, with running water from all taps and showers working again much faster than I thought - just 90 minutes. This is definitely a company I will recommend.

Polite, prompt, helpful, knowledgeable, informative and very fair price We have used this company for many years and would thoroughly recommend them.

Heat Tech came out at very short notice to repair a hole we had in a gas pipe - fixed swiftly and calmly....highly recommend!

The email the day before reminding me that the Service was due to be carried out was very helpful and assuring. The Engineer, Ian, arrived on time and carried out a full Service within the schedule and budget. No hidden extras. Ian was extremely pleasant and approachable and a pleasure to deal with. I have no hesitation in calling on the services of this Company for any future problems that may arise.

Tap started leaking - Heat Tech Responded quickly - Efficiently and fair price. I continue to spread the word for this company, they well deserve the business. He once came out on a Saturday night 6.00pm and fixed a leak for me. They put the customer first - a bit of a rarity today!

Mark came out to my house and fixed something my my heating very quickly and well. I asked him to diagnose a water pressure issue which I’d had a quote on from another contractor and he gave me a much better solution which was very cost efficient. The team did a great job of this - awesome to meet a female plumber also!

Many thanks to Sapphire and the team for the speed and efficiency of rerunning gas pipework following leak. Having anticipated being without gas for weeks, Heat Tech had me up and running in days. They kept me informed throughout. Punctual and courteous.

I called Heat Tech and spoke to a very nice person called Sarah who explained Mark the engineer would be calling me back to ask a few questions about what was needed as my radiators were not working sufficiently. Mark called back and we discussed the procedure for a power flush for my heating system, which is 30 years old, so I wasn’t expecting miracles but that’s what I got. The job was booked in and two very professional guys called Neil and Lewis arrived, very polite and easy to talk to and they started the job. I also had to have a new circulation pump fitted. The guys worked hard as my rads were very gumped up but that didn’t bother them they cleared them and my radiators are working brilliantly. I was chuffed and so pleased I’ve found Heat Tech and will be definitely using them again. It’s was so refreshing to have the work carried out so professionally by experienced people. A big thank you to the Heat Tech Team from start to finish.

Heat Tech installed my boiler with other works in March 2012. They have serviced my boiler installation ever since and always carry out a first class job at a very reasonable price. Their general plumbing is also of a high standard. Great, reliable service. 100% recommended.

Mark from Heat Tech Services emailed me v promptly after I had called him to ask him to service our boiler which was also not working very well, the Heat Tech guys arrived promptly and on time, carried work out efficiently and neatly. The team were polite, helpful and knowledgeable and the price was very reasonable.

Mark’s Heat Tech Services arrived promptly and on time, carried work out efficiently and neatly. This was a small job but they came out the following day despite them being busy and at a very reasonable price. Both guys were very polite and helpful.

HeatTech were quick to respond to my initial query for a replacement boiler, did a comprehensive on site assessment and gave me a detailed quote. Work by George and Lewis was professional, courteous, on schedule and friendly. Any problems on site were discussed and quickly resolved. Highly recommended.

Very quick response and knowledgeable professional engineers. Have used on several occasions which says it all.

Mark is a professional heating engineer who came around promptly at an agreed time. He completed work to our satisfaction that included; replacing a heating pump, some pipe work and bleeding our heating system. All the work was done at a reasonable cost that was quoted in advance.

I have used Heat Tech for a number of years now and they continue to deliver prompt, friendly and reliable service.

Third call-out in last few months for different problems! Prompt response, quick to attend, efficient and helpful service.

After contacting about 7 plumbers who never got back to me, Mark was recommended through a friend. Him and his team ended up coming back 3 times in one day to fix separate problems (its an old house) and i honestly can not fault their work. I am forever thankful for their help and would recommend them to anyone without hesitation.

For the second time this year we have had to call Mark out for an issue. He went through it all on the phone and arranged for someone to come out on the day. Which we were extremely grateful for esp in the cold. We can’t fault the service with Heat tech, thank you for your help Mark and team.

I called Mark early in the evening about a significant toilet leak, as well as a leaking kitchen tap which had gradually been getting worse. Two members of his team came early next afternoon and soon had the repairs done, for what I consider to be a very reasonable price. I have used Heat Tech over the last three years for a variety of jobs, including installation of a new boiler, and have nothing but praise for the professionalism, courtesy and skill of Mark and his team

Following an attempted home repair that failed and water could not be turned back on, a call to Mark at Heat tech in the late evening proved the best decision of the evening! Mark was calm, helpful and immediately reassuring. He came out within 30 minutes of our call for help. All was restored and the water back on, we could not fault any part of the service and professional help he gave. A great service indeed.

I had a problem with a leak from my boiler. I called Heat Tech at 5:30pm and spoke with Mark who was extremely helpful and arranged for Francesco to visit the house first thing the following morning. Francesco was amazing, he was very polite and studious and I would fully recommend Heat Tech based on my experience.

My elderly parents had an issue with their upstairs toilet which was preventing them from being able to use it. I got Heat Techs telephone number from a recommendation on the Nextdoor App. And am so pleased I did. I spoke to Mark and he spoke to my mother within an hour, obtained the information he needed and was able to give a very reasonable quote very quickly. They had some very professional, polite chaps over on the same day and my mum was very pleased with the work they did and was able to use the toilet on the same day. I can't speak highly enough of the service I received from beginning to end. Top class! I would definitely recommend.

I had a problem with an overflow pipe in the loft and also a radiator that wasn’t working. Heat Tech arrived on time the next day and solved both issues and also answered questions about the heating system which was really helpful.

My boiler failed early one morning, just before Christmas and I rang Heat Tech and got immediate help which solved the problem temporarily and then it was followed up by someone coming to the house and fixing it. It was a very good service

Having seen wet floorboards by the hot water cylinder, a phone call to Heat Tech led to a quick visit in order to identify the problem. Fortunately a new hot water cylinder was not required but a sticky heating valve controller and some reconfigured pipework was needed to resolve the issue. As it was just before Christmas and a complete shut down until the New Year, we were delighted with the quick service and the problem was sorted. We switched to Heat Tech in mid-December 2021 as British Gas Home Care were completely unable to sort out a problem in a timely fashion and expected us to wait until after the New Year without central heating for an engineer to call.

We had a mains water leak which had obviously been going on for some time with water saturating an internal, but load bearing wall. I had no hesitation calling 'Heat Tech Services' as I knew I would receive an excellent and prompt solution at a fair price. As it was the weekend and Mark was busy, he could not actually get to us until the following week. He was incredibly helpful, giving the best temporary solution, including what we could do ourselves to save time and money before they could come to fix the pipe. The pipe was excellently and quickly fixed by the end of Monday. The site was left clean and clear of debris. I felt like a very stressful situation was calmly, expertly and promptly sorted without causing a financial headache. I had a query regards moisture on the pipe after the job was completed and Mark thoroughly explained the possible reasons and asked me to call back if I was still concerned. The workers mended the pipe perfectly and saved us a lot of hassle over a very busy Christmas period. Thank you. I cannot recommend Mark and his team highly enough.

Heat Tech engineer George came the day after I called, to replace our water pump and check the boiler because the heating was not working properly. He was excellent and a credit to Heat Tech. I had never used the company before but had been recommended. They are just excellent and very helpful and accommodating and reasonably priced. I have no hesitation in recommending them and would certainly use them again.

I've previously engaged Heat Tech for some repairs at my home and was happy to go back to them with a recent query. Mark was really helpful over the phone and managed to solve the issue without the need for a call out and so without any cost. I've recommended Mark and Heat Tech to friends and I know they've been happy too.

We have the top of the range Home Care cover with British Gas. We were left without hot water for over a week (not classified as an emergency according to Dyno, who carry out plumbing work on behalf of British Gas), and no sign of resolution. We contacted Mark and although we live outside the area his company usually covers, he agreed to help us. He came as a recommendation from two people we know. Mark ordered the parts and carried out the repairs in a very timely and professional manner, thoroughly testing everything before he left. He left the area spotlessly clean. From our initial contact with Mark, right through to completion, Mark kept us informed each step of the way. If the software allowed, we'd give him more than 5*. We are indebted to Mark and his team member for coming to our rescue and putting an end to lukewarm showers in the gym / local swimming pool, in winter. We cannot recommend this company highly enough - so professional and efficient. We felt we could trust Mark totally.

Heat Tech came in good timing to solve boiler pressure problem; later central heating was on, but a new leaking found, Heat Tech came again in late afternoon to finish a reliable service, so far boiler OK.

We noticed a small leak coming through the downstairs ceiling. It proved very difficult to find but once it was located the exact cause was established. The remedy involved installing a new shower which Heat Tech did most efficiently. A big job for a small leak but one which had to be done. I'm pleased with the new shower. All in all a very satisfied customer. I would have no hesitation in using Heat Tech again and would definitely recommend their services.

The engineer arrived on time and was friendly He carried out the service on my boiler in a confident manner and was tidy and efficient. He also helped set my timer which I was having problems with. He suggested it was faulty. When I asked him if Heat Tech could fit a replacement he said yes and suggested I contact Mark Ockendon. I was extremely happy with the service.

Mark and his team have carried out annual services on my domestic boiler for some years. The team are utterly professional and work quickly, efficiently and to the highest standards. Charges are fully explained in advance and on each occasion I have been invoiced for the pre agreed sum. Excellent.

I called Mark to get my hob commissioned after my kitchen fitters fitted the kitchen, he came round very promptly, spent half an hour making sure my gas supply was ok but more importantly made sure I was strong enough to turn the gas off if the need arose.

Mark and team are brilliant. We found we were losing pressure on our boiler, and then during other works discovered a leak under the landing floor. Mark came quickly, replaced poor work by a previous plumber and replaced with proper copper pipes. With my elderly mum in the house getting this sorted was vital and Mark came up trumps. We also requested our annual heating service and had an appointment within days. Prices are very fair and Mark runs his business in a very professional way.

This was the annual service of our boiler and was carried out with customary efficiency, speed and courtesy by Sapphire and Tom, who left the area in an extremely tidy and clean state.. The cost is extremely reasonable and was precisely as stated. As is customary, no complaints at all over the work.

Only required a Boiler service this time. Undertaken very speedily. Efficient, clean and tidy and friendly. Would thoroughly recommend.

My first time using Heat Tech Services. The appointment was pre-booked, a reminder was sent and the polite and professional engineer arrived as scheduled. Excellent service and value for money.

The work was the replacement of an old and faulty Ch wall thermostat. The original engineer - Sapphire - was ill and unable to attend but her replacements actually arrived before the original appointment time and completed the installation efficiently and courteously. Moreover, they provided a clear, patient and thorough explanation of the workings of the new,' smart', thermostat. A very good, professional job.

Had issues with my radiators. Mark was very helpful initially, advising on what are the options to resolve and proposing course of action over multiple steps. Team completed the initial job, but this did not resolve the issue. Tried to speak to Mark a number of times after this - he was difficult to get hold of, refused provide a quote for the next step and preferred to say this is the cost per hour. Said he would call back but did not multiple times. Overall initial service was good, but not impressed with the follow-up and issue still not resolved

I cannot recommend Mark and his team highly enough. They have recently fitted a new hot water cylinder for me which was completed efficiently and provided excellent service. This week I had a water leakage in my kitchen which I noticed in the evening. I messaged Mark and he replied later that evening asking for photographs and details. He then agreed to come out first thing the next morning and within a couple of hours had replaced the pipes and fixed the problem. I couldn't be more grateful to Heat Tech.

I've been a Heat Tech customer for a few years now and would recommend Mark and his employees. Works are always done precisely and well. Most recently I've had a gas safety certificate done, boiler service and new toilet fitted. In the not so distant past we've had an outdoor hot water tap installed.

We had no hot water which British Gas failed to diagnose or rectify for days. We called Heat Tech, who came and fixed the problem immediately. Sapphire and George were so efficient, friendly, competent and a pleasure to deal with.

Called for a couple of plumbing problems in a newly purchased property. They were polite, punctual and clearly knew what they were doing. Very reasonable prices. Highly recommended.

I have used Heat Tech for a number of years. They are prompt, efficient and Sapphire is an excellent gas engineer.

My boiler stopped working and there was no hot water in the house. The engineer from Heat Tech Services Limited came next day. Identified the problem with the boiler straightaway. Fixed the issue promptly. Very professional

Heat Tech eventually solved a problem with my underfloor heating which had previously seemed insoluble and alongside that dealt with a minor plumbing emergency that happened while they were here. I have used them on three occasions now, they are reliable, communicative and keep expense to a minimum by establishing as many details as possible about a job before they come so they have the right parts/equipment with them. Highly recommend.

Very quick response, gentlemen who came round were polite and "knew their stuff", potential problem analysed, identified, got the system working. Highly recommend

Responded immediately to my somewhat frantic phone call at 8.30am Sunday morning when I had water showering from the ceiling. Quickly located and fixed broken pipe in loft, hoovered it dry and cleared out all soggy insulation. Very pleased with the service indeed and wouldn't hesitate to use them again.

Very professional and on time fir appointment. Explained all that was needed. Boiler serviced and a new water pipe put in. Which was placed neatly. They were very friendly and helpful. Very pleased with their work. Would highly recommend the company.

I have had cause to use this company twice recently and both times I have found them to be responsive and professional in their approach to the work and issues. Good and consistent communication, they did also turn up when they say they said they would.

I needed a heating engineer in a hurry. Heat Tech were recommended by my sister. Phoned them in the afternoon and they were on the doorstep at 8:30am the following day. I would normally be wary of any tradesperson that could respond that quickly, but they were highly recommended and didn't disappoint. I will happily use them again

Rang to remind me that service was due, guys arrived on time and completed job in the time frame specified at booking. Cannot recommend this firm highly enough.

Discover reason for poor water flow from bath and basin taps in main and ensuite bathrooms of a new build development. It emerged the fault was with the taps themselves - wrong specification for hard water area - both blocked with limescale and narrow-gauge Flexi hoses restricting the flow. Removal of diffusers improved flow significantly in one tap but didn't eliminate the problem in the other. Tap judged faulty - needs to be replaced. In the interim plumber used his initiative by switching the better performing tap to main suite and relegating the faulty tap to the less used bathroom pending sourcing of new fitments. The bath tap, due to the position in which it has been installed, is inaccessible for maintenance so was advised to refer back to the construction company for remedial action. The engineer stuck to the brief until he had provided a working solution and a recommendation for future action. Subsequently HeatTech followed up with a phone enquiry to ensure customer was happy with the outcome and to endorse the engineer's recommendations. Full marks for customer service. The cost was very reasonable. I use Heat Tech for annual boiler maintenance and have every confidence in their ability to deal with other issues as evidenced above.

I have used this company for years and see it, deservedly grow. Knowledgeable reliable and clean work at a fair price. They have also come out and helped when I had gas or plumbing emergencies, a local company who take on and train local apprentices too.

As usual, great work, carried out quickly and efficiently. Mark has a great team who do a great job.

Second time I've used and the same pattern of being fast, reasonably priced and most importantly having extra specialist knowledge that actually solves the problem in the best way rather than just doing an easy short term fix. They really know their subject in detail. Thoroughly recommend.

Used Heat Tech on a Sunday evening when my 90 year old mum's heating didn't seem to be working properly. Someone came out within 30 minutes. They sorted the problem and also solved 2 previously unknown problems over 2 subsequent days.Heating is now running fine and mum is very relieved. Thank you

I have used Heat Tech a few times now, and go back to them because they've been efficient and prompt. When our old house throws up quirky, unusual problems they've done what it takes to find a solution.

Heat Tech installed my boiler near 14 years ago (extremely professional installation). Found my boiler was leaking late Wednesday night for which Heat Tech attended the next day. The issue was quickly identified and remedied. Heat Tech knows the products they work with extremely well and I have 100% confidence in their technical knowledge. Fantastic service - thank you.

We needed the hob gas pipe moving to allow a new electric oven to be fitted. Phoned Mark, and he managed to fit us in and send one of his engineers around the next day. She was super efficient, and when she had finished helped us with the new (electric) oven. Thanks for the really quick and helpful service.

Work carried out speedily and to my complete satisfaction. All problems solved by operators who acted very efficiently and courteously at all times.

Heat Tech Services Limited were a pleasure to deal with. They found time to fit me in to their diary as I had a heating breakdown. They fixed the immediate problem and returned to fit the problem quickly and efficiently. They were tidy, courteous, professional and charged as quoted. I wouldn’t hesitate to use them again and will be asking them to take on the regular servicing of my heating system.

Very happy with the prompt service from Mark and his team. Two machines used to freeze the pipes before changing valves on leaking radiator pipe work without draining down. Result

I Whatapped Mark on Tuesday and by 10am on Wednesday morning the problem was fixed. A fast and efficient service as ever.

On New Year's Eve I discovered the central heating boiler was leaking and dripping onto the kitchen worktop. Mark came, identified that it was the heat exchanger leaking, telephoned the manufacturer and arranged for an engineer to visit on 3 January. It was all done so efficiently and was a great relief to me. Very grateful for his swift action.

Boiler went down Christmas Eve, freezing Christmas. Saved by heating engineer I never knew existed. Recommended by friendly plumber. How right she was. Mark arrived at first possible opportunity, scrutinised the boiler from every point of view - he was definitely a problem solver. He certainly had an eye for detail and discovered some little problems where things had just disintegrated, goodness. Should have been serviced earlier but at the time we were in Lockdown and I have been isolated ever since. He changed the fan, burner gasket, and ignition electrodes on the spot and went on to tighten manual air vent in the airing cupboard - getting rid of a leak was unexpected benefit. All this, no fuss. I was left with warm radiators, proper hot water and the emergency heater redundant, thank goodness. Now the house is nice and cosy and I thank Mark. Added bonus I now have a heating engineer to call on to do the annual service. Result, excellent!!!

It doesn't look as though the team need another recommendation but I am delighted to add one. Another prompt, thorough and efficient visit. Top marks to Heat Tech - they are excellent!

Heat Tech installed a new Vaillant boiler for us. Following a site visit, their initial quotation was issued very quickly, was in a clear format with various options available, and was very reasonable. We were able to book in the work very quickly. The young lady who carried out the work was excellent. She was very knowledgeable, polite and professional. My wife, in particular, was mightily impressed that a woman carried out the work! After the installation, we noticed that some air had built up in the radiator system, which we understand is quite normal when a new boiler is installed. Heat Tech returned very quickly to release the air etc. They also registered our guarantee for us directly with Vaillant. All in all, we are very happy indeed with the service offered by Heat Tech.

Great company who deliver on time, at sensible prices and carry out top quality work from a great team. Response was great from initial contact. Work was done on time by Sapphire, who was brilliant. Tidy, efficient and will now be my first go to for any plumbing needs. Well done 👏

Many thanks to Mark for his extremely prompt and efficient service. Following a boiler breakdown we were visited by 0900 and the fault (a broken fan) quickly identified. A replacement part was speedily obtained and by 1100 hrs the boiler was back in operation. I would heartily recommend Heat Tech!

Sapphire from Heat Tech services our boiler today. Arrived early, very professional and efficient. Really pleased with Heat tech

The required work was carried out with thorough and knowledgeable efficiency, with a considerate and friendly approach and at a very reasonable price. Highly recommended!

Mark's team had to switch out old boiler set up with loft tanks etc and replace with combi plus some extra rads. A big job that took all week for 2 people. Job completed as planned and all done efficiently. We had a few snagging problems but Mark made sure that one of his team came out to fix them quickly. Have used Mark before and will definitely use him again. Reliable service and good at diagnosing tricking problems!

I remain grateful to Mark for somehow squeezing me into his busy schedule at short notice when our gas boiler broke down last week. But equally appreciative of the highly efficient, thoroughly professional service received. Would definitely recommend.

Heat Tech services (Mark) installed a new boiler for me in the summer, which was done very efficiently. In September we started to have problems with the hot water as the new boiler kept cutting out. Mark couldn't have been more helpful in identifying the problem (failing Shunt Pump) and fixing it. He ensured that we weren't left with a problem. I wouldn't hesitate to use his services again.

Having not used this trader before, I was very impressed with the service provided and would highly recommend them. I needed someone to repair my toilet cistern as it was constantly trickling through the pan. They contacted me quickly to arrange my appointment and confirmed it in an email with details as to who to expect the following day. Neil came out as planned and fixed the problem. Excellent service.

I used Mark for the first time for a boiler service. He was on time, carried out a thorough service and worked in a clean and tidy fashion. Mark also carried out a separate repair to a radiator. Overall I was very happy with the high quality of work and service.

What a brilliant service. Same day response (within hours). Mark came diagnosed the problem immediately and boiler parts were replaced within 2 hours. Very pleased with price charged. This is the first time we’ve used Heat Tech and we were really impressed by Mark’s depth of knowledge, professional approach and attitude. Sarah also was extremely helpful when taking our call. Can’t recommend highly enough.

We contacted Marc at Heat tech to a boiler service at my mothers house through personal recommendation (my mother’s neighbour). Marc was very accommodating in setting up the appointment and the fact that my mother is not comfortable with people in her home. Sapphire, the technician, turned up on time and set to work immediately on servicing the boiler. We hardly noticed she was there and upon completion she explained what she had done and how we should pay. This worked extremely well for us, the boiler is now safe for the winter and my 94 year old mother remained totally unstressed by this process.

Mark Ockenden and his team have looked after our boiler and other plumbing needs for several years. The latest service was carried out without fuss on the day scheduled. Mark is a highly skilled engineer who takes great care in ensuring that the job gets completed to the highest standards. Highly recommended.

This is the first time I have used this company for my annual boiler service. Sapphire was extremely efficient and carefully explained the work carried out during the service. I was impressed by her attitude.

Really helpful. Excellent advice and service. We had a problem with the flow of cold water in our bathroom after we had left a tap on which resulted in our sink overflowing. I got in touch with Mark following a recommendation of a neighbour. He got back to me quickly and we spoke on the phone. He analysed what the problem probably was and resolved the problem.

We engaged Heat Tech Services to replace our old boiler with a new one. The service provided was exemplary in all respects. In fact, the new boiler was delivered to us on the previous evening, ensuring an early start on the Thursday. Sapphire arrived promptly and her work - with the able assistance of Seb - was first class in all regards. She quickly found solutions to a couple of minor problems and completed the fitting speedily, neatly and efficiently, and left the work area spotless. Moreover, she explained the working of the boiler clearly and patiently and was unfailingly pleasant and polite. I will have no hesitation in engaging this company for future work.

Excellent Service from HeatTech. Solved a number of problems for us recently to our great satisfaction. Would highly recommend.

Neil and Ethan were on time, polite, informative, considerate and entirely professional. I cannot recommend Heat Tech enough. This is the third time I have had need of their services for different issues and each time they have worked efficiently, solved problems and not been too expensive. All of the staff that I have met have been an absolute credit to Mark who seems to run the business like a well-oiled machine. Thanks so much.

I had not used Mark's Company for a few years, being away. His team arrived promptly as arranged., and carried out the work quickly and efficiently. Communications were timely and to the point. As before, I was totally pleased and satisfied with the experience.

Toilet blocked. Plumber Sapphire came and worked very hard to clear. Would recommend. Did offer to fix toilet back down afterwards.

We've had a number of tradesmen, builders, etc. doing various bits on our house over the past few years, and more often than not we've been let down. Not so with Heat Tech! They came to do the job quickly and went above and beyond to make sure it was done properly. I wish everyone cared as much about delivering great service as Heat Tech does!

The first time used Mark and his team, hugely impressed with the knowledge, attention to detail, and prompt reliable service. Arrived exactly when arranged and efficiently diagnosed and fixed problem. Brilliant.

Mark carried out a heating/plumbing survey on a property I am about to purchase. The whole experience was carried out professionally and efficiently and at a reasonable price. I will be asking Mark to carry out the recommended work once I move into the property.

Kieran from Heat Tech serviced our boiler. He was prompt, polite, tidy and observed Covid guidelines. I appreciated receiving an email reminder that the service was due, along with confirmation of the appointment and email invoice to pay by Direct Debit. This is the second year I have used Heat Tech for my boiler service and expect to use them again the future.

Used Heat Tech for the first time for a boiler service and will certainly use them again. Booking was quick, price was as expected, and the booking of the appointment and the visit by Heat Tech engineers was fantastic. This is the best service our boiler has had in 5 years! (Previously British Gas)

My pure water tap and undersink water purifier were fitted efficiently and at the time and date agreed. The fitter Neil was polite and I was very pleased with the work he did. I would thoroughly recommend Heat Tech Services.

We had an ancient boiler, attached to questionable pipework which had been modified by various plumbers over the years. The boiler was removed, and the space completely cleared of any remaining pipework. New boiler fitted in the same position, and every pipe re-run in a very professional manner. This meant it looked great, and also gave us much more space, as the pipework was positioned more tidily against the walls. Sapphire, our lady plumber worked without a break over two days, until the job was done. All left neat and tidy. So pleased we are awarding Heat Tech the maintenance contract as well.

I called Mark Ockenden of Heat Tech Services on the morning of June 1st about a leak from a pipe in the kitchen. He arrived with colleague about two hours later, & solved the problem by repairing the pipe quickly & efficiently. I was very pleased to have the job completed so quickly.

Mark attended a water heater issue raised by my tenants. He attended when promised, had great communication throughout and resolved the problem on the day. I only researched the company online as now reside in Australia. I would recommend Mark (Heat Tech) to anyone as he is exactly the type of trusted tradesmen you want to deal with, will definitely use them again.

Mark and the team have replaced radiators for us and fitted a new boiler recently. They have done a fantastic job, arrived when they said they would, done a fantastic job and stuck to the quote. Highly recommended.

Mark responded quickly to my email regarding the central heating. Edin came round, identified the problem and replaced the faulty component. Excellent service throughout and at a reasonable price. Thank you!

I contacted Heat Tech Services in the morning in relation to a fault on my boiler, it wasn't producing hot water. Mark got in touch with me about half an hour later and at 2 pm I had an engineer at the door. He diagnosed the fault immediately and fixed it. The engineer even waited some 10 minutes for access while I returned home. Other companies were going to come the following week and, with 2 small kids at home and an elderly grandmother, I desperately needed hot water in the house. Honestly, I couldn't rate this company highly enough. I was so impressed with their service. I used them for the annual boiler service last year and will certainly continue using them in the future. Thank you, Heat Tech!

We were delighted with the speed and quality of the work, removing hot water cylinder and associated plumbing, fitting new thermostatic valves on all my radiators fitting the new boiler and commissioning the system.

Burst pipe late afternoon on Xmas Eve sorted quickly with no fuss. Subsequent boiler breakdown and replacement handled extremely professionally. Detailed explanations at every stage. Prompt arrival every morning, quiet except for instructions, and Covid protection guidelines adhered to by all workmen (and ladies!). Work completed on time and within budget. A small problem with the new boiler (Manufacturers' fault) was remedied quickly at no extra cost. Will be replacing British Gas insurance policy (as the earliest they could send an engineer was a minimum of 2 weeks!) with annual service by Heat Tech. Cannot recommend highly enough.

The inspection, testing and maintenance was conducted very professionally and under Covid rules well handled.
