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 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.

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.

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.

Power flush & fitting 7 thermostatic control valves
Customer Service
Quality
Value
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).

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 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.

He was polite and took the trouble to explain the work as he went along. I would definitely recommend.

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.

Also, despite an unforeseen problem (with some pipework behind a plasterboard wall) Mark quickly dealt with it and kept to the original quotation.

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 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 quickly responded to our initial contact and arranged a time suitable to us. Mark was knowledgeable and polite most importantly Mark was honest what we were honestly expecting was a costly new boiler. It resulted in a very cheap, in comparison, fix. Highly recommend.

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 arrived punctually to replace the HW cylinder. He spent considerable extra time identifying issues that we were not aware of and fixed them e.g. installing a new pump and its valves, introducing a gate valve for the header tank in the airing cupboard and replacing a drain cock gland. Consequently he was with us from 9.30 am to 8 pm on a Friday evening. He kept us informed at all stages. He takes great pride in his work and as he said "I won't leave until the system is up and running efficiently". He is very curteous and approachable. He is an outstanding plumber and we will use him again.

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

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!

We had a problem where our heating system was making loud banging noises. Other heating engineers had been, and rather than getting to the root of the problem, tried to get us to spend large amounts of money. We called Mark, as he came highly recommended. We weren't disappointed. He spent two hours of his Saturday afternoon with us, as he looked to diagnose the problem. He identified it. Not only were we happy to give this friendly and professional man the work, but he also completed it to a very high standard. Highly recommended.

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.

Very professional and accommodating during the installation of our boiler. Was the only person able to replace our boiler in the same spot in the kitchen were others wanted to run pipes all over the house to put it in a place they thought was best. Our Combiboiler works perfectly and any issues along the way was resolved quickly. No job too big or small.
