Mark Hopkinson Domestic Gas Heating Engineer

I have used Mark to install and service my boiler for several years. I trust him implicitly not only because I have complete faith in his technical expertise, but also because I have found him to be honest, fair and reliable - and a really nice chap. What more could anyone ask of a service provider?

I consider myself very lucky to have come across Mark, He is one in a million. I had a boiler installed two years ago, the installers convinced me that the new boiler and cylinder would not fit in the area where the existing one was. They put it in the cupboard in the small bedroom. I was never really happy with this arrangement but thought there was no other option. Recently, I saw a guy working near where I lived, I asked for his opinion, he put me onto Mark. After initial contact Mark, told me no problem to do what I required and would quote, this he did by the following day. Price was good so I went ahead. His work was exceptional, did everything I required, put everything back in place. I was impressed with his knowledge and experience. Finished the job when he said he would, no hidden Suprises, cleaned-up, also serviced my boiler and Gas fire. I have since called him back again to fit a new radiator, again good Job. Mark is a very affable, good humoured, friendly, and most of all a very experienced engineer I highly recommend him and will always use him for any future work.

Mark did a great job of fix my water tank by replacing the elements. He worked solidly on the job and cleared away any mess. I would definitely use him again in the future.

Contacted Mark late in the afternoon 2 days ago, regarding a leak I had discovered in our airing cupboard. He said he'd call in on the way home and have a look at the source. He confirmed our suspicions that it would be the water cylinder and said he'd let us know a price when he got back. He was unable to ring because of getting home late but called first thing yesterday morning to tell us a price. We agreed for the work to be done, as it was much less than we had anticipated, and he said he was able to fit us in today. He arrived on time and was polite and courteous. He set about draining the system and went out to get the cylinder from the supplier. Not out for long and cracked on with the job. After getting to a stage where it could be tested, there was a secondary fault identified with the ball valve in the loft tank, so a price was given and agreed on, and off he shot to get the part. New part fitted and on to a secondary test. Mark also found a faulty diverter valve (hasn't worked properly for as long as I can remember) and this was priced up. He had to shoot out again and just made it to the supplier before closing. The work is all complete within 48 hours of discovery, and all for less than we had originally anticipated just for the cylinder. Mark has also been able to advise on some preventative maintenance to mitigate the risk of a potentially expensive malfunction. All in all, very impressed with his professionalism and standard of work.

Mark attended to look at a leak in our loft and fit a hob. The parts needed for the leak were obselete, however, this did not stop him traveling to multiple suppliers until he found a stockist. He worked quickly and efficiently, when a problem occurred he was able to think outside the box to solve it. His work was excellent and we would thoroughly recommend him.

Mark is trustworthy, reliable , diligent and professional. He does what he says he is going to do, when he says he is going to do it, gor the amount quoted. After care is superb. Very pleased indeed with the advice, support and workmanship. Would definately recommend.

Mark came round to rewire our central heating controls and fit a Hive system. Whilst completing the work he noticed a problem with our Hot Water thermostat and replaced it for us. All his work was within the budget he quoted and he did not charge us anymore labour to resolve any of the extra issues. Our Heating is now working better than ever before we are so pleased with his work and he is a really nice guy too!! Would highly recommend.

Mark replaced our old boiler with a combi boiler. He did the job without a lot less fuss than we anticipated, no seeming problems and every thing was done professionally and very neatly. He was a nice pleasant man and polite. He explained how every thing worked and I would recommend him to do your jobs.

Mark fitted us a replacement gas boiler for a competitive budget. He did the work over two days and did not start before 10am which allowed us to be up and about without rushing in the morning. His work is professional to a high standard. He is easy to get along with and has a pleasant demeanor. If you need a new boiler I would recommend him to you.

Mark Hopkinson gave us a competitive quote, and importantly completed the job very neatly indeed (important as the new boiler would be installed in a newly refurbished Utility Room, and we did not want brand new surfaces etc to be damaged). He did an excellent job, even better than expected, exceptionally neat, and at a very competitive price. Really pleased with his work. Also liked that he did the job over 2 days - ensuring it was done to a high quality standard, not rushed, corners not cut. Looks great, works superb.

Gas boiler replaced at agreed time and within agreed budget. The reason I used Mark was because I knew that the work would fully comply with legal and trade requirements and be done to exacting standards. Eg:- spacing between pipe brackets is uniform. The standard of Mark’s workmanship goes beyond that I have experienced with tradesmen in the past. Would definitely recommend if you want a perfect job done.

Mark came recommended by neighbours and was able to provide a clear quote for replacing an existing boiler. He explained very clearly the options and benefits of different installations. Having made the decision Mark provided a clear timescale for the work which was completed on time. We are delighted with the system and due to Mark’s work have a 10 year parts and labour guarantee on the boiler. We would recommend Mark without any hesitation.

From the word go we knew we were in safe hands with Mark. A brilliant Gas and Heating engineer, he's incredibly knowledgeable, efficient and fitted us a brand new Worcester boiler at a competitive price. Mark is very thorough in his work and gave detailed explanations on how to work our new system. He was friendly, polite and a delight to have in our home. We are extremely pleased with the finished product and look forward to welcoming him back next year for our boiler's first service. We wouldn't hesitate in recommending his services to anyone. Thank you, Mark.

When Mark came to estimate the work needed he went into great detail as to what to expect on the days when the work would take place. He answered all of our concerns. When he started the work he was methodical and assured as to what was being done. It's not a clean job replacing a boiler but he kept the mess to a minimum. He said that a further part of work may be required relating to the gas supply pressure. He quoted that work seperately but as it turned out that work was not required. All the work was done more or less on schedule (by 1 additional day) but the quote there were no additional costs. Mark is an excellent and conscientious worker and I would not hesitate to recommend him for any work in this area.

I would not hesitate to wholeheartedly recommend Mark Hopkinson. He quoted for a power flush , fit one radiator, a change in a radiator pipe work and convert my heating to a closed system. He was professional and efficient. He worked methodically and completed the work with minimum fuss, mess and intrusion. As with all things, other issues cropped up and we had to change another radiator and add three bleed valves. Additionally he also went to my mothers house and a changed two port valve

I contacted Mark to replace radiator valves. The quote was very reasonable and the work was carried out efficiently. Mark was friendly and courteous and I would definitely contact him for future repairs etc to my heating system.

Mark came to replace our ageing back boiler with a new Combi boiler. He turned up when he said he would, kept us updated with progress and next steps and delivered a neat tidy new boiler installation. Highly recommended (good at Pop Master too!) Thanks Mark.

Mark was recommended to me and his work didn’t disappoint. He arrived as planned, was pleasant, very tidy and completed the work to fit a new boiler quickly and efficiently. I’d recommend him and his work.

I would not hesitate to wholeheartedly recommend Mark Hopkinson. He was professional and efficient. He worked methodically and completed the new boiler installation with minimum fuss, mess and intrusion. He was polite, respectful and helpful. I am very satisfied with this trustworthy professional being in my home.

Called Mark on a recommendation from a friend when my hot water started playing up (very low flow). Mark was prompt and professional and when later that day an additional issue occurred (which was only noticed once other was repaired), a quick call was all it took for Mark to finish his current job and come back to our boiler, diagnose the fault and source and fit the part that day. Now that is what I call service. Would definitely use him again, Nice guy.

Very pleased with the work carried out by Mark. Highly recommend him and we have a much warmer house

Mark came to fit new boiler in loft, and remove old back boiler. Was very professional and polite, explained in detail what was involved. Clean worker, excellent job, has been back to do yearly service. Very happy, would recommend.

Mark responded and serviced the boiler on the same day, very exceptional service. Tidy worker very reasonable price I would definitely recommend

Mark has regularly serviced our boiler and central heating system for a number of years and recently installed a new boiler for us. Yesterday, we had an emergency (unrelated) problem and Mark gave advice over the phone and arrived to assess the situation first thing this morning before returning to fix the problem once he had bought the appropriate parts. We are very grateful for his prompt, efficient service and excellent knowledge and skill.

Mark did what was agreed in his quote and to the price quoted. The power flush was quite prolonged due to the large amount ogf "rubbish" accumulated in the radiators, (witness all the large cold areas in the radiators) due to the previous house owners neglecting system maintenance and took a considerable time to clear. He was considerate at all times explaining everything needing to be done and kept to the quoted price. He was helpful and communicative all through the process. Nothing went wrong and the indication is that the system should work so much more efficiently in future having cleared cold areas in the radiators. The heating has not been used yet as the weather is too warm but the improvement should be very noticeable. I intend to let Mark know this when the time comes. No mess was left (Mark used adequate floor protection to avoid any mess).

My boiler needed a new pressure relief valve, pressure vessel and pressure gauge. I found Mark via this website and had a good experience. In all my communications with Mark he was polite, friendly and helpful. His replies were prompt and his explanations clear. He kept his appointments and arrived when he said he would. If there were any changes of plan he let me know. He worked quietly and without fuss and did not leave a mess. I was happy with his price and will definitely call Mark again for future work. Overall I am very pleased.

Mark came to repair a heating pump valve leak, and carry out a boiler service, he carried out the repair quickly and efficiently- and also went to get a new heating pump after he found a valve seized on the old pump, he provided one valve for no extra charge, he has a positive attitude and brilliant customer service provided. I would recommend Mark unreservedly, and will have no hesitation in calling Mark again when I need more work being done. Thank you.

Due to unforeseen circumstances, Mark was unable to spend as much time on the installation initially as he would have liked, but after resolving his workload, he installed the new boiler to a very high standard and we could not fault his workmanship. His cheery nature and 'can do' attitude was so refreshing, and he did everything possible to accommodate or requirements. The budget was kept to, with no hidden surprises, and everything regarding costs was fully explained prior to the work commencing. I would have no hesitation in recommending Mark as he is an extremely competent Gas and Heating Engineer, and in fact we have pencilled him in for our first boiler service when it is due.

Mark was a very competent plumber and knew exactly what he was doing so had complete trust in his workmanship. He cleaned up before leaving and we would definitely recommend him to friends and family.

Mark deserves 10 stars, not 5. He is friendly, knowledgeable and happy to help in any way he can. Professional, communicative and we will definitely be using his services again.

Mark provided a very competitive quote to replace our 18-year-old Glowworm boiler and instal a Worcester Bosch boiler, a new pump and valves. The work was completed to a very good standard and the system has run perfectly since. Although the job took a bit longer than expected due to some unforeseen complications, he kept to the original price and even provided an electrician to tidy up the wiring at no cost to us. He was polite and took the trouble to explain the work as he went along. I would definitely recommend.

Mark came to us Wednesday evening as we had no hot water/ heating and he found a fault in our boiler which he had to order a new part for. He fitted it Saturday morning and all was sorted. No call out fee and a very quick turn around from diagnostics to resolution. Very pleased to have hot water / heating again. We would highly recommend Mark. Thanks again

Our boiler failed and needs replacement. While Mark was fully booked and could not fit a replacement boiler for us this year, he kindly spent time on the telephone remotely diagnosing the problem so we could get our boiler working again. There was nothing in it for Mark, but he's just a very helpful and knowledgeable person. We are most grateful and are leaving this review to share our experience.

Mark fitted a new hot water tank and repaired the boiler. I am very happy with the work, everything works well. Mark always kept me up to date with progress and start and finish times. He kept to the estimated cost, there were no surprises. Mark was always friendly, courteous and professional.

Mark attended promptly although he was busy. He quickly diagnosed and rectified the boiler fault and also carried out a service afterwards. We were very pleased with Mark's work and his very reasonable charges. We would definitely use his services again

Mark was called because our mother had no hot water or heating because her boiler and programmer were not working. Mark visited at short notice despite working on another job. He diagnosed the problem and got the water working before coming back 2 days later to fit a new programmer and service the boiler as requested. Mark provided great service and value for money. We very much appreciated his work for our mother.

From initial visit and quote to installation of new boiler Mark answered all questions quickly and clearly. We found Mark to be very pleasant and friendly. All the work was carried out to a high standard and we are very pleased with what he has done.

1. Returned enquiry within 24 hrs 2. Met scheduled appointment and agreed outline costs at visit 3. Mark Hopkinson was one of three plumbers who responded to my Request for Quotation and was comfortably the lowest cost and appeared confident in doing the installation. 4. Following 3 above my RFQ was updated and he responded well to my required revisions some at zero cost and one (power flushing) at an acceptable cost. 5. The installation was carried out well despite some difficult work in restricted loft space, albeit taking slightly longer at 4 days than anticipated. Communication throughout was first class. He also offered the first annual service at zero cost. Will definitely use again.

Mark installed a new boiler for me. Everything from his initial visit to the quotation and subsequent installation was clearly explained, and questions and queries I had were quickly answered. I found Mark to be very pleasant and courteous, and he just efficiently got on with the job. Also, despite an unforeseen problem (with some pipework behind a plasterboard wall) Mark quickly dealt with it and kept to the original quotation. All Mark's work was carried out to a high standard, and I'm very pleased with my new Worcester boiler (which comes with the peace of mind of a 10 year guarantee). I highly recommend Mark, and will be contacting him again soon to fit a new gas cooker hob.

We found Mark on the Trusted Traders Which site, called him out to service our Worcester Bosch boiler. He was on time, very efficient and very polite, will be using him future.

Friendly, reliable service. Great quality work and prompt service. Would highly recommend . Mark came and fixed two leaks in the pipework and pump around my hot water tank. He was happy to come and quote the job, the quote was really reasonable and he was able to complete the job before I went on holiday! Mark is friendly and chatty and nothing was too much trouble! Fantastic service

I invited a number of quotes for a new replacement system boiler complete with smart thermostat. Mark was one who quoted and was competative as he is a sole trader and therefor VAT exempt on his turnover. We agreed a start date and payment terms and he duly arrived on the agreed date. The old boiler (some 40 plus years) was an old cast iron unit and very heavy located in a cupboard on the landing. He enlisted the help of a friend to remove it successfully. He organised scaffolding to access the outside roof to install the new flue and removed the old steel flue system. The new boiler was installed with neater pipework and the boiler condensate routed to the outside via a pump as the boiler is not on an outside wall. The smart thermostat was one he had not used before and it gave him some headscratching but he persevered and with the help of a friend had the unit working OK. The installation took a day longer than estimated but the end result was totally satisfactory. If you want a plumber that you can rely upon to do a good job in a friendly manner and explain all that he is doing then Mark is your man to employ.

I recently moved into my house and was confronted with a new boiler that needed to be connected to a smart app to work. Not helpful as it took 2 weeks to get an internet connection and I also have personal experience of this heating app and didn’t want it again. I found Mark through a local news magazine and rang him requesting a female friendly control panel. After the initial visit to assess the job he duly disconnected the existing system and installed a very female friendly control panel which I am very happy with. He also cleared the airlock in the water pipes... job done! I found Mark to be friendly and helpful and would definitely call upon him again in the future

Mark serviced our boiler. Competitively priced; came when agreed and did a thorough job. Would definitely call on again and would recommend.

Mark has carried out a number of gas heating jobs for me recently, boiler service, replacing a faultly motorised valve, installing new raditors and fernox magnetic cleaner. From the first time I met Mark it felt like I knew him for years. In my experience, finding quality tradesmen who are friendly, honest, reliable and professional is a rare thing, Mark ticks all these boxes. Thanks!

Mark has just fitted a new Worcester 38CDI combi-boiler into our home and a very professional installation was carried out on time, at a very competitive price. He was very helpful when quoting, recommending types of boiler and explained in detail what work was involved in removing old and installing new. I would recommend Mark as a very experienced and trustworthy engineer, who I shall use in future for annual servicing.

Checked for boiler fault. Returned with new circuit board. Fitted part and fault resolved. Mark was considerate, turned up when he said he would, problem sorted. Also excellent value.

Mark fitted a new combi-boiler in my mums house. He gave her a fully detailed summary of all work to be undertaken, estimated price and the timeframe the work would take to complete prior to the job. All of which he was true to his word. He was professional and trustworthy. He explained exactly what the job involved and was happy to explain anything or answer any questions my mum had. There was a blockage in the radiator system and Mark came back an extra day ...and stayed all day ..until it was sorted. The house is now lovely and warm and two radiators that havnt worked in a long time are now working perfectly! Mark has a natural manner about him that makes you feel completely confident in his work. He is very friendly and chatted to mum a lot..in fact she will miss seeing him everyday so she is very happy that he is going back one last time ! I would recommend Mark to everyone and I can completely understand why he is a Which Trusted Trader. Mark is awesome!

Mark carried out the work very well and was friendly too. I would recommend and use him for future works.

Mark recently carried out some work to both move and install some radiators at my home. He did a great thorough job and will definitely use his services again in the future. I can highly recommend him to others.

Mark come to fit a new gas cooker, he was round the same day to check to order in parts and was round as soon as they came in even though it was a Saturday, he couldn't have been more helpful, he was quick, efficient, tidy and easy to communicate with, Would highly recommend.

Mark recently installed a new gas hob in my kitchen. Whilst on site he also diagnosed, and rectified, an unconnected issue. All this despite being due to fly off on his holidays shortly after. Mark is professional, knowledgable and reliable. Highly recommended for when you require either a GasSafe engineer or need some general plumbing carried out.

Mark fitted our new boiler 3 years ago and has seviced it regularly over the years. Recently we called upon Mark's service due to our boiler not providing hot water. Mark was able to diagnose the probably and mend it in a speedy mannor. Mark was also good at advising how to prevent the probablem happening again. Mark always clears up ang mess he makes too anf is recognisable by his trade logo. I would recommend his services.

Mark assessed the problem with our heating the same day I rang, fixed an appointment and arrived on time. He worked quietly and efficiently, was pleasant and professional, and did a great job.

A friend put me in touch with Mark and I am very glad that he did! Mark did a site visit and talked me through the system that he recommended before following up with a detailed and competitive quote, We're chuffed to bits with the new boiler, we have proper hot water for the first time in goodness knows how long! Mark covered the carpets with dust sheets to protect them and left everything clean and tidy. A thoroughly decent chap - thanks Mark! :)

Mark is very knowledgeable about his trade and quickly diagnosed the problem with our boiler. He described the actions he was going to undertake and even undertook some additional, discretionary safety checks to ensure all was well. All this was undertaken at the initial quotation given. Mark is thorough in his work, professional in his approach and courteous in his manner. I have no hesitation in recommending him.

Mark was friendly and helpful. He explained what he was doing while he was moving the placement of the gas pipework to my new hob.

I found Mark on the Which? Trusted Traders website after we had been let down by another gas engineer who didn't turn up to fix our heating. Mark was very efficient and quickly sorted out our problem even though he had been working all weekend and was very tired. I would definitely recommend him.

Mark removed our old boiler and thermal store and replaced them with a new combi-boiler. His expertise and working ability was clearly evident throughout and he always made time to explain what was being done. His workmanship was excellent and we can highly recommend him.

I found Mark on the Herts CC website and I'm glad I did. What a nice man. Serviced my boiler and fixed a radiator that wasn't working. Friendly and professional. Really nice, genuine guy. I will certainly be recommending him to friends and family and definitely use him again myself. Thanks Mark

Mark came highly recommended from a friend in the gas fitting business and carried out a from scratch, full central heating installation in a 1930s 3 bed semi between 30th October -10th November 2017. He met with us, surveyed the house and made a recommendation for a system based on his extensive knowledge and experience. The Worcester Bosch 36CDI is a superb combi which we're very happy with. Quiet in operation and speedy in response it more than meets our needs. Having a full installation is quite a disruptive job with floors up etc but with Mark advising which room he was going to work on in advance, made living in the house whilst the work progressed, bearable. Mark took great care throughout the installation and always consulted on key decisions e.g. Position of radiators, flue etc. He kept us fully informed throughout the installation and was always friendly and reliable. We would highly recommend him- Brian Spiers and Carolyn Paskins

Friendly and professional, not surprised he gets a five star rating, and it's a five from me too. I would definitely use Mark again, and have no hesitation in recommending him.

I found Mark on the Which? Trusted Traders website and I am so pleased I decided to go with him! I wanted to have a gas safety check carried out on a house I am buying and I had called a few other companies, one of which tried to sell me something I didn't need! Mark was very professional and easy to talk to; he explained what the process involves and assured me that I didn't need to pay for the extra service that the other company had mentioned, therefore preventing me getting ripped off! He also updated me about the outcome afterwards as I wasn't actually present when the test was carried out because the current owners are still living there. I would thoroughly recommend Mark to anyone looking for a gas engineer! I have saved his number and will be using him again for our yearly boiler service and any other gas work we may need. Thanks very much Mark! I really love it when I receive good customer service!

A friendly trader who did a good job and was quick about it too. He gave advice for the future and didn't push me to get him back to do an extra job, although I would definitely use him again. Very impressed.

Mark kindly came round promptly one evening when I thought I had a gas leak via my gas hob. Mark came well equipped to test whether there was a leak and kindly put my mind a rest. A week later after I purchase my new gas hob Mark came round and installed it. His workmanship is very neat and he even showed me some of the safety features on the new hob. I have saved his details and would definitely use again.

Great service and a pleasure working with Mark. He has serviced our boilers for many years and has always given fair prices and an honest opinion.

Having read the reviews on this site relating to Mark, I decided to contact him for a service on my boiler. He did not disappoint. A friendly, experienced, tidy professional who responded to all my questions whilst completing a thorough service. Highly recommended.

Great job by Mark who just changed our boiler for us, turned up to quote when he said he would work completed on time and no hidden costs. Totally reliable and would highly recommend him.

I've used Mark to move a radiator, fit a thermostat and service my boiler. I've always found him considerate, efficient and punctual and leaves everywhere very tidy.

Mark was an unknown tradesman to us but we decided to go with him. He was very professional, knowledgable and very good at what he does. He gave really good solid advice. He repositioned and fitted a new boiler for us. His work is first class. I highly recommend him for any plumbing work. The only annoyance I had with him was we had to wait nearly 3 weeks for him to be free. This acts as a good indication of how sort after he is as a professional ! He arrived as promised and completed the work as agreed. Thanks for a great service. We will certainly use Mark again.
