Water pressure has never been so good.
Customer Service
Used Heat tech for the first time and they were able to fit us in on the same day. The engineer (Saphire) immediately understood what was needed and the whole job was done in half a day. As a result the water pressure from the mega flow doubled. We have lived here for 15 years and never had the pressure so good. Definitely will use them again.

We have been using Heat Tech for a number of years for plumbing and heating and cannot praise them enough. Mark has built a fantastic team and we have never been let down. Mark always puts himself out if we have anything urgent and his prices are usually very reasonable. We wouldn’t hesitate recommending Heat Tech to anyone that needs plumbing or heating services. Thanks Mark and team!

Fantastic service
Customer Service
I called Mark at Heat tech on Tuesday 13th, he arranged for George to come on Wednesday 14th. They arrived, as promised, at 8:30 am, the work was carried out within a couple of hours. They were so tidy and polite, the workspace was left clean and tidy after having two radiators removed from both sides of a wall. collateral damaged done to the floor in the dining room which was okay as floor is coming up anyway, but I was kept informed at all times as to what had to happen. The next good surprise was the invoice I received, very pleasantly surprised at the charge for the job. I was recommended Heat Tech by a neighbour and am so glad she did, any plumbing jobs I need doing in the future will be with Heat tech, and yes I will definately be recommending them to others in the future. Thank you again gentlemen for your stirling work

Impressive Company
Customer Service
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

First Class
Customer Service
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

Very prompt and efficient
I phoned Mark and he sent an engineer George round the same morning. The pump on our heating system was replaced. We are still working through other issues on an old heating system.
