Radiator replacing

Having replaced our hot water tank previously we asked Mark to quote to replace most of our 37+ year old radiators including new thermostatic valves plus adding new valves to our relatively new towel rail radiators. Most of the radiators were non-standard sizes by modern designs. Mark's quote was competitive and he was able to program the work to be done in the summer. He did the work within the 3 day timescale quoted and was able to adapt the existing pipework to fit the replacements in a way that looks very nice. Once again we were highly satisfied with his work and we can recommend him for all things heating related.

Mark had serviced my 22 year old boiler for last 2 years. This year it was time to get a new one installed. Mark quoted me for a new Worcester Bosch. I agreed to quote and we arranged an installation date. On installation day Mark arrived with dust sheets to protect my carpet. He is a very knowledgeable engineer. I am very happy with the end result. The new boiler is so quiet compared to the old one which was 24 years old when she passed on 😢 Can highly recommend Mark.

New boiler installation. I have used Mark for years. He regularly serviced my old bolier (26 years old) and has now installed my new boiler. Arranged and completed an amazingly efficient and tidy job within quoted timescale. All paperwork and guarantee fully explained and paperwork provided. 5 star recommendation.

Mark efficiently completed a few jobs and was able to accommodate me at short notice. He takes great care to ensure everything is working correctly before leaving and is very knowledgeable. As always Mark was professional, cheerful and reasonable. I will definitely use Mark again.

Mark came round on the same day we called him to discuss a leaking Hot Water tank. He identified quickly that the tank required replacing and also suggested moving its location to give us more space around it. The quote was provided later that same day and the work was done the following week on an agreed day. As he was draining the central heating to replace the tank he included replacing a failed plinth radiator. Mark's work was to a high standard and he ensured that everything was covered to avoid dirt and water. We cannot praise him highly enough and have already asked him to return later in the year to quote for replacing several very old radiators. It is clear Mark is a tradesperson who is not only capable but is also prepared to offer sensible suggestions to improve the overall job. The work was completed within the allocated day and for the agreed cost.

Called Mark to repair a leaking drain down stop cock and he repaired it with the minimum of fuss. Have used Mark for over four years for both plumbing repairs and boiler servicing, and on each occasion I have always received exceptional and friendly service, and this was no exception. I would recommend him without hesitation.

Mark replaced and fitted a new hot water cylinder, corrected the pipework which was prone to airlocks and replaced some damaged sections of pipe. Mark is very approachable and knowledgeable and works to a very high standard. Communication throughout was always very clear. All the work areas were kept clean and he tidied up afterwards. This is the second time I have used Mark and would have absolutely no hesitation in using him again.

Mark replaced four radiators, removed a fifth radiator and capped pipes and also serviced the boiler. He installed all the radiators perfectly level always checking with me the locations I would like them to be fitted and altered pipework very neatly. Mark works to a very high standard and is really approachable. He kept the areas clean and tidied up afterwards. He stayed very late as not to leave me without hot water or heating and made sure everything was working correctly before leaving. I would have no hesitation in using Mark again.
