I called Mark with the intention of asking for a quote to replace my boiler. As it is cannot be repaired I needed the work carried out quickly. 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.

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.

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.

I had my boiler serviced and the fan replaced as it was very noisy. George did the work and was very efficient and pleasant. The fan had to be got in and Mark/George provided good communication so I wasn’t wondering when it would be done. Best recommendation I can give is to say I will be using them again.

We needed a plumber who was qualified in working on unvented pressurised hot water systems to replace a pump, some radiator valves and venting equipment. This included draining the system and refilling, pressurising and testing. Fortunately we were aware of Mark Ockenden of Heat Tech Services from a previous job and knew him to be an excellent engineer for this type of work (and a wide range of others of course). Mark provides a very efficient and punctual service with excellent communications. We were able to discuss the job by means of emails with photos so he was fully prepared for the work on arrival. I felt very confident in Mark's skills and advice. The work was completed very quickly in a calm and tidy manner and the hot water system is working perfectly again.

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.

I almost feel reluctant to recommend as I don’t want him to get so busy he can’t come and rescue us! Having lived in the area 15 years our plumbing experiences have been pretty dire before meeting Mark. He is prompt, gets on with it and doesn’t over charge. This last job was a proper rescue job for a flood on a Sunday morning and he was there within the hour.

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.

I have used a number of different plumbing companies and individuals over the years and I have to say that Mark at Heat Tech is a clear cut above everyone we have ever used before. 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 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 needed to have a second boiler pressure gauge and filling loop installed as the existing controls were all in the loft and being in our seventies this was extremely difficult for us to access. We contacted HeatTech who gave us a quote which we thought was very reasonable and asked them to go ahead. The engineers arrived punctually were friendly and helpful and carried out the work quickly and efficiently. We can highly recommend this company and we will definitely use them again.

Full Boiler system extraction and system replacement - VERY professional

Outstanding job by Mark, Sapphire and the rest of the team. Very professional in the initial diagnosis of the old boiler system; transparent on what the problems were and the options open to me; competitive quote and invoicing process for the new combi boiler system which they recommended to replace my old system. The old boiler system was quite a antiquated installation but Sapphire and her team got to work straightaway and were simply excellent in extracting that and installing a fully functioning replacement Vaillant combi boiler and NEST thermostat system - and in a very fast and efficient time too. The Heat Tech team are highly recommended (they came recommended to me too), very trustworthy and I will continue to use their services in future.

Burst pipe late afternoon on Xmas Eve sorted quickly with no fuss. Subsequent boiler breakdown and replacement handled extremely professionally. Detailed explanations at every stage. Prompt arrival every morning, quiet except for instructions, and Covid protection guidelines adhered to by all workmen (and ladies!). Work completed on time and within budget. A small problem with the new boiler (Manufacturers' fault) was remedied quickly at no extra cost. Will be replacing British Gas insurance policy (as the earliest they could send an engineer was a minimum of 2 weeks!) with annual service by Heat Tech. Cannot recommend highly enough.
