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.

When part of my heating system failed in December I groaned to myself as finding a good engineer in winter is usually difficult. However, from my previous experience of Heattech, I knew they would help if they could. I rang Mark and he asked me for a few details and James came round the next day to fix the problem for a very reasonable price. It's helpful that they take the trouble to ensure they have the right parts with them as best they can as fixing it in one visit saves a lot of inconvenience. Highly recommended

Mark has been working for us for some years now, always boiler services and installation of two boilers at our different addresses in the past year. Not just boilers but complete refurbishment of bathroom, utility room, wet room and all kitchen work. I have no hesitation in joining the other testimonials for Mark in stating that his work could not be better, often offering better advice and solutions to any problems that might arise. Frederick

James and George had the dubious pleasure of fitting a new toilet pan and bath mixer tap to ancient plumbing (lead pipes) as well as removing some redundant pipework and replacing the monoblock tap in the kitchen. They were polite, friendly, did a great job and were scrupulous in cleaning up and disposing of waste. I'll certainly be using Heat-Tech again when I next need any plumbing or heating work.

I would have no hesitation in recommending Mark and his team and feel very lucky to have worked with such an honest, reliable expert in his field. The whole team are exceptionally reliable, polite and considerate tradesman. I felt very comfortable leaving my wife and young child to work with Mark directly and he is always over delivered on everything. As the saying goes in life "you get what you pay for" and HeatTech is well worth the investment.

Mark was recommended by a friend a few years ago and he has since fitted a number of new and replacement central heating radiators. I had always found Mark and his team to offer a very efficient and reliable service and earlier this year decided to ask him to take over our boiler service as our existing contract had become ridiculously expensive. The service took place last week and it was quite a revelation to see the thoroughness of the work carried out compared to the work carried out previously.

A new word is needed as 'plumber' is not good enough
Customer Service

Mark is a revelation. After being mucked around by plumber after plumber, to finally find someone who does such novel things as 'turn up when they agree to' and 'do the job that they said that they will do' is a revolutionary experience for me. Really, he should not be called a plumber but something grander. Maybe a 'Water and gas containment and direction engineer'. Mark was presented with a range of problems ranging from a boiler service that was three years overdue to a shower that had leaked ever since it was installed (causing damp in the room below). In all, he had more than half a dozen problems to attend to over his first two visits and to say that everything went perfectly would not be true. But that just adds to the experience. Things in life go wrong, but it is how we deal with them that is the mark (excuse the pun) of what and who we are. Mark dealt with a problem when one thing didn't go right and instead of making an excuse, said "I have mucked up" and proceeded to put it right. I strongly recommend Heat Tech for anyone who wants not only wants a competent Water and Gas Containment and Direction Engineer but also expects good timekeeping, a responsible attitude towards his work and a fair reasonable price.

Mark from "Heat Tech" did an excellent job getting to the root of the problem with our (somewhat elderly) boiler and persevered by initially renewing the 'Thermo-Coupler' and then replacing the boiler's gas valve (which he had to go and obtain from one of his suppliers, on a Saturday). The work was all done very efficiently and swiftly - and thankfully, we now have hot water and heating again which was very important to us, as my husband has complex health issues. Along with being very knowledgeable about all kinds of boilers (including the not so new-fangled ones!) - he was friendly, courteous and respectful at all times. I would always recommend him.

Great service from Mark and Heat Tech over the past couple of weeks to fix a faulty combi boiler. I received an immediate response to my initial enquiry and a visit was booked for the same week. Some parts needed to be ordered and these were fitted the following week, completely fixing the issues we'd been experiencing. Mark has also been great at suggesting options for ways to improve our set up and avoid potential issues in the future. Would thoroughly recommend Heat Tech and very glad of the recommendation from a friend in the first place!

We used Heat Tech after putting out a request on Streetlife (as we wanted to use a local company) and we were so pleased we did. Our Hob had been leaking gas which resulted in it being cut off by British Gas, so it was imperative to replace it. The level of service was second to none, Mark was extremely helpful, reliable,efficient and the cost was competitive, I wouldn't hesitate to use the company again and we were able to Keep it Local.

Heat Tech came to us via recommendation, They replaced our OLD boiler system and added a radiator, while we went on holiday. The job was completed before we returned. We came back to a clean & tidy flat. Mark came back to explain the Programmer on the boiler and to check we were satisfied with the jobs done. Good work, excellent service, very good communications. Highly recommend. Andrew & Trudy

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.
