Excellent Heat Tech service

Heat Tech engineer George came the day after I called, to replace our water pump and check the boiler because the heating was not working properly. He was excellent and a credit to Heat Tech. I had never used the company before but had been recommended. They are just excellent and very helpful and accommodating and reasonably priced. I have no hesitation in recommending them and would certainly use them again.

I received a recommendation for this company, and used them for the first time to replace a faulty heating timer and a boiler service. The engineers did what they said they were going to do, when they said they were going to do it for a reasonable price. I am happy to recommend them without any reservations.

I have used Heat Tech for many years and now have had some radiators changed this week. The whole process was straightforward with a preliminary visit and quote through to the work being done on time and for a fair price. Every member of the team has been professional and competent. I highly recommend Mark and his team.

Fix problem with Vaillant boiler heating system and room thermostat

Central heating was intermittent and not responding to the thermostat. After having a couple of locally recommended engineers look at the system and fail to properly diagnose the fault I came across this Which site which contained many satisfying reviews. Talking to Mark on the phone it was very clear that he was the engineer I was looking for. As a retired engineer of 60 years in electronics development I found we could discuss my problem successfully. Heat-Tech engineer George, came over to checkout the system and found it not to be wired according to published standards and recommended that rewiring was needed to enable efficient fault finding. Subsequently he got the heating working but there were occasional fault modes occurring and a new electronics board was needed. After fitting a replacement board the system is now working correctly. Costs of labour and parts were good value and I would call them again if required. I'm pleased with the fast and competent service from the company and would recommend Heat-Tech as a first choice. Thank you Mark and George.

HeatTech are known on the Estate I live in and I had already had a recommendation. The work I needed doing was a new shower unit in my walk-in shower, a new kitchen tap with added water filter and a new cistern valve in one of the other bathrooms. The hardest part of the work for Sapphire, who did the shower was having to remove tiles in order to get the piping out without upsetting the other bathrooms using a power showers. Fortunately I had some tiles left from the original job about 30 years ago. She grouted those tiles really well and no-one would know anything had changed, except me, of course! Sapphire had two young helpers for the other two jobs. I am extremely happy with their approach to the work and the efficient and friendly manner in which it was done and would certainly recommend HeatTech. Helen Dean

Second time using Heat Tech and again excellent service. My elderly mum had no hot water but Mark diagnosed where the problem was, over the phone. Amazingly they were able to come out the same day and had the problem fixed within twenty minutes. They were very clear explaining what the problem was, which impressed my mum, as she has dementia and often struggles to understand people. Can’t rate them highly enough.

Gas Leak

Had suspicious smell of gas. I decided to phone Mark Ockenden of Heat Tech Services as his firm are registered Gas Safe Engineers. I have used their services for Gas boiler installation, maintenance and general plumbing for many years. I have found his staff, well qualified and highly effecient. Mark arrived on time. He tested for a leak and determined it was minor but needed to be attended to. He found the leaking valve, which was embedded in my fireplace surround. To avoid damaging the fireplace, he lifted carpet and adjacent floorboard, cut the pipe and capped it with a soldered repair - all with my agreement. He put everything back in place and it looks just as it was before the repair was carried out. As usual - excellent service.
