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

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.

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.
Customer in Buckinghamshire Posted on 04/11/2023 , work completed 25/10/2023
The trader replied (on 08/11/2023)
We are very sorry that you felt our service was not up to scratch. Expansion vessels are particularly prone to failing after a few years and this can happen at any time, even shortly after a service. At the time of the service the vessel air pressure was low, which is not unusual (and one of the reasons why regular servicing is important). It was topped up with air in the usual way. If the internal bladder, which is impossible to see, had been weak, it may have been the final straw which caused it to split a few days later. We did try to re-inflate it when you called us back but it had clearly failed, so unfortunately it to be replaced. Sorry but these things do happen sometimes.
Great service!

Fix problem with Vaillant boiler heating system and room thermostat

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.

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.

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.

Leak by hot water cylinder

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.

We have the top of the range Home Care cover through British Gas. We were left without hout 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.

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.

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.

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.

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.

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.

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!!!

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.

Marc was very accommodating in setting up the appointment and the fact that my mother is not comfortable with people in her home.

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.

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.

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 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.

I'd used HeatTech before (after finding them on TrustedTrader) after they managed to fix two faulty valves then had meant we had no heating in the house so was fairly confident they could address the issue that the underfloor heating has stopped working. After a quick call with Mark we had figured out what the problem was (another faulty valve) he came around and replaced the value. Two of his team came round a couple of days later to make good. Hopefully this valve will last a while but can't fault HeatTech's work. They arrived when they said they would, identified the issue and fixed it and made good. Would use again

He installed a new Combi boiler, with all that that involved, disposing of the old boiler and enormous tank. He also took away an old radiator and replaced it with a new one on the opposite side of the room. Since then, he and his team have regularly serviced the boiler. Mark has an excellent work ethic which he passes on to new members of his team. I have no hesitation in recommending Heat Tech.

We had 2 issues (Blocked bathroom sink and a broken radiator valve) - He and his team turned up at the agreed time, got straight to work and resolved both issues with amazing efficiency. Totally professional. Extremely pleased and will be getting Heat Tech to take over my annual boiler checks if they can fit me in.

I have been using Heat-Tech for installation and servicing of my central heating boiler since 2013. Also general plumbing. Just had another annual comprehensive boiler service carried out in the usual efficient way. What I like about Heat-Tech is that if I want clarification or help on any c/h or plumbing matter during the year I just have to phone Mark. He is either instantly available with advice or phones me back very promptly.

I have used Heat Tech for several years for regular boiler maintenance, and for occasional urgent repairs. Mark has always sought to be dependable, and if unable to do the work himself, has monitored the work of members of his team to ensure all has been done adequately. I am more than happy to recommend Heat Teach, and would say that I endeavour to use them whenever possible, knowing that repairs and advice will come with experience, a professional approach and wise judgements.

We have used Heat Tech for our last two services and have been impressed both times. We noticed we have a leaking valve and unsure how long it had been like that, also unsure what to do in this Covid situation we called Mark and thankfully said he could come and fix it. He came and fixed the problem and we maintained social distance. Continue to be happy with their service and would 100% recommend them to other people. Thank you Mark.

Heating system was losing pressure in 2-3 hours, and Mark tried to seal the leak, which was believed to be in the concrete screed below wooden tiled flooring. This, in spite of 2 attempts, did not work, so we asked for the cheapest alternative, which was to have new piping to the 4 radiators affected. Because of the time of year we were anticipating it to be done in 4 weeks but, in fact, it was started within a week and completed in under 2 days. Mark was on a short holiday and his staff did the work very swiftly and we felt were efficient, tidy and charming. Mark came and checked the work done on his return. Finally, the cost of the work was good value for the time involved.

We have been using Heat Tech for many years now for servicing and repairs and wouldn't dream of going anywhere else. Mark and his team have always been completely dependable and very professional. My last issue was that our heating system broke down on Christmas Eve (just gone). Whilst I knew that this would be an awkward time to expect anyone from Heat Tech to do anything, Mark came round on his way back from Christmas shopping to have a look at the problem, which wasn't an easy one to diagnose or repair. Nonetheless, across three visits that day, Mark managed to solve the problem, replaced a faulty valve and get us up and running with a fully working heating system again over Christmas! Needless to say, we were delighted and relieved, and despite the time of year, the bill was very reasonable too. I would have no hesitation (and frequently do) to recommend Heat Tech to anyone that like us, truly values a reliable, professional and totally trustworthy service from any contractor.

Mark was recommended to me and with good reason. He was the third plumber/heating engineer to attend in the 8 days we were without heating or hot water. Expensive solutions had been diagnosed by the others e.g. new boiler! They say that planning is the key to success... In advance of the appointment, Mark asked me to send photos of the boiler, the pump the immersion valve etc. On the day of the appointment he attended with his (very polite, articulate and proficient ) young apprentice. They were outstanding. Heating system drained, pump replaced, radiators warm and hot water restored within 90 minutes of arrival. Having received the photos, he had been able to ensure that he had all possible parts on board should they be required. I am very impressed by the professionalism of all aspects of Heat Tech, not least as the problem was swiftly identified and fixed at a fraction of the cost I had been advised by the companies.

Our heating/hot water system failed us over the bank holiday.... no hot water. I phoned Mark at 8.30 am on Tuesday, and he was at our place by 9.45, diagnosed our problem, and had replaced the faulty part in 40 minutes. This is exemplary service ..... I know Mark has a very full work schedule. I also admire the fact that Mark was accompanied, as he has been on previous occasions, by an apprentice ( on this occasion a young woman) who he was instructing and giving hands on experience while he worked. On the whole highly skilled and experienced trades people who work for us are reluctant to take on apprentices ..... it's easier just to do the work yourself, and the paper work is daunting. Some of these are near retirement, and a lifetime of experience will go with them. So well done Mark for passing on your skill to the next generation.

Around lunchtime we realised that we had lost heating and hot water. Looking at the boiler it was obviously dead. We called Mark Ockenden at Heat Tech and he called back within 20 minutes. He came to the house as soon as he had completed his other work for the day. It was clearly a difficult problem to resolve but he persisted and a replaced transformer got our boiler working again.

Our gas boiler failed on the Saturday morning before Christmasand would not reignite. This required a call out and action to avoid not having heating over the Christmas period with little time to resolve the problem.

He analysed that it was a control valve problem and replaced the part from his stores in the van which avoided further delay or a return visit.

Mark was honest to say that he is so busy that he cannot commit to a boiler installation in the next week or so. However, what he did give me was unbiased, valuable advice during a long telephone conversation and this advice has been very helpful in my decision for my new boiler.

I selected HeatTech on the recommendation of a neighbour. Communications were good - when the engineer was delayed by his previous job he rang in plenty of time to explain that he was going to be late and why; if only more tradespeople would do this. When he arrived, the engineer was polite and effected the service efficiently. I certainly plan to use HeatTech again and am happy to recommend them.

On the recommendation of a neighbour, I arranged for HeatTech to provide an annual service for my boiler. Arranging the appointment was easy. On the day, the engineer realised that he would not complete his previous job in time to meet the appointment time for me, so called with an explanation and a revised ETA - if only more tradespeople would do this. He met the revised ETA and carried out the service efficiently. I will use HeatTech again and, like my neighbour, am happy to recommend them.

I have used Heat Tech over the past 3 years to repair a boiler then annually service the boiler and prepare gas safety certificates together with installation of a new radiator. He is reliable, professional and courteous and I would recommend his company.

Heat Tech completed a boiler annual service and safety check. It was the first time we'd used them and we selected them primarily because they were local in Chorleywood. Very pleased with their professionalism and service. When booking Mark called me back as promised, he arrived when he said he would and completed the work quickly and was clear, patient and polite in explaining what needed to be done. Will use again and would recommend to others.

Everything about Heat Tech left me feeling pleased that we decided to invite Mark and his team to help us out. They telephoned us when they said they would, arrived punctually to do the work, were considerate and polite in explaining what needed to be done and completed the work very professionally. Also Mark resolved what could have been quite a complex repair very quickly and straightforwardly - saving us potentially a lot of money in the process. So we now have a fully functioning hot water system, a repaired toilet cistern and discovered someone in whom we have a lot of confidence. This was the first time we have used Heat Tech - I will have no hesitation in working with them again when we need some heating or plumbing expertise.

My toilet flush was getting worse and worse and eventually I decided to look for a plumber. I realised that Heat Tech, who serviced my boiler, also did general plumbing. Mark came the same day I rang him and sorted it all out. Couldn't ask for better service!

I found Mark on the Which Trusted Traders' site and rang him for help. I had been left without hot water for a week after the company I have insurance with for maintenance on our central heating, supposedly serviced our boiler. Their engineer returned to my house four times and each time failed to remedy the problem. Mark spotted what was wrong almost immediately and the hot water was back within the hour. He even fixed a problem with my outside tap while he was here. I cannot recommend him highly enough. Needless to say I have cancelled the contract with the heating insurance company and I will be using HeatTech for all future maintenance. Megan S.

Mark was recommended to us a few years ago by another of his clients and we've been contacting him for all our plumbing needs since then. From fitting new boilers, to repairing redundant (but still live) mains supply pipes leaking into our kitchen, to replacing troublesome toilet seats, his service is always completely satisfactory, perfectly prompt in an emergency and very pleasant. I wouldn't hesitate in recommending him to others. In fact, I already have done.

Would recommend using Mark and his team. Mark came and discussed options on new heating system explaining to this "old lady " in great understandable detail. The work was done while I was away and I came back to a very warm clean house. Thank you George. Mark again explained the running of the boiler. Mark is a very pleasant person to deal with. I understand from my neighbours that the whole team were very friendly and considerate. Thanks everyone. Not the cheapest but certainly the best. Will certainly keep using Heat Tech.

Mark and his team fitted a new boiler and hot water tank in four days. They were prompt, tidy, and explained all the work they were doing. Prior to the work, mark had explained the alternative solutions. Whilst at the top end of the estimates I had, I would not hesitate to recommend them as the result has given me an excellent system.

My central heating stopped working and Mark was able to tell me over the phone how to get it working again until he could he could come and fit a new motor to a motorised valve.

We had a new heating system installed with a combi boiler and some replacement radiators. This also involved taking away all the old water tanks and piping. The job took a week and we were delighted with the quality of the work and the team were polite, clean and tidy and a joy to have around. The new system works beautifully and we would recommend Heat Tech unreservedly.

We are SO relieved to find a heating engineer that is honest and professional. Just before Christmas, we very nearly fell victim to an unscrupulous plumber who insisted that a new boiler was our only option when ours failed. The hard sell made us very uncomfortable so friends recommended we call Mark. Thank goodness we did! Mark was able to identify the problem immediately - and very kindly took the time to explain how he was going to fix it. Thanks to his knowledge and skill, our boiler is now up and running and there was no question we needed a new one! I'm so grateful for Mark's honesty and have absolutely no hesitation in recommending him.
