Excellent service from HeatTech. They were very helpful with my problem over the phone, got in touch when I had asked them to, quickly arranged a visit to sort the problem out, and worked quickly, efficiently and tidily to carry out the work. No hanging around, had the relevant parts to hand, and charged a reasonable price

Heating system was losing pressure in 2-3 hours, and Mark tried to seal the leak, which was believed to be in the concrete screed below wooden tiled flooring. This, in spite of 2 attempts, did not work, so we asked for the cheapest alternative, which was to have new piping to the 4 radiators affected. Because of the time of year we were anticipating it to be done in 4 weeks but, in fact, it was started within a week and completed in under 2 days. Mark was on a short holiday and his staff did the work very swiftly and we felt were efficient, tidy and charming. Mark came and checked the work done on his return. Finally, the cost of the work was good value for the time involved.

I had a combi boiler installed by Heat Tech Chorleywood, replacing an older boiler and water tank. An excellent experience from first to last. A very thorough survey, followed by a clear and professional quotation from Mark; responsive and intelligent customer relations; and a team of installers (Sapphire and Edin) who absolutely knew what they were doing, took an obvious pride in the quality of their work, didn't cut any corners, worked their socks off, and did a superb job. On the basis of this experience, Heat Tech Chorleywood gets my enthusiastic recommendation.

Boiler broke down, no heating or hot water. Heat Tech reviewed the problem within 48 hours and diagnosed the issue which was fully explained. They then proceeded to book us into the earliest slot a week later when the problem was resolved. They were highly professional, efficient and good value for money. We would definitely recommend Heat Tech and will be booking them for our annual service.

Had a pipe leak in my downstairs ceiling crawl space. Heat Tech responded to my request the next day, located the leak and repaired it. From the time I contacted them (voicemail) to when it was repaired was ~24 hours. They were very reasonably priced and friendly and I would have no concerns recommending them.

On Thursday we had the power off all day for our electrician to update our control panel. It was the coldest day of the year so we couldn't wait to switch the boiler back on when the work was complete. Unfortunately, the boiler failed to function. Mark responded to our call that evening but couldn't identify the problem over the phone. At 9.00 the next morning his team arrived and got the boiler working again. They were polite and efficient and adhered to the Covid guidelines. We have a warm house again, for which we are extremely grateful.

Great Job
My mother had a problem with her heating/water, lives on her own and is elderly. I was told that heat tech was very good and reliable. I phoned Mark and he sorted the problem within two days, as soon as he could. My mother was delighted and his work was excellent and he was polite and tidy. The problem was fixed within 2 hours. We would recommend without doubt.

Used Heat Tech for the first time for a boiler service and will certainly use them again. Booking was quick, price was as expected, and the booking of the appointment and the visit by Heat Tech engineers was fantastic. This is the best service our boiler has had in 5 years! (Previously British Gas)

Exemplary Boiler Fitting

We engaged Heat Tech Services to replace our old boiler with a new one. The service provided was exemplary in all respects. In fact, the new boiler was delivered to us on the previous evening, ensuring an early start on the Thursday. Sapphire arrived promptly and her work - with the able assistance of Seb - was first class in all regards. She quickly found solutions to a couple of minor problems and completed the fitting speedily, neatly and efficiently, and left the work area spotless. Moreover, she explained the working of the boiler clearly and patiently and was unfailingly pleasant and polite. I will have no hesitation in engaging this company for future work.

We contacted Marc at Heat tech to a boiler service at my mothers house through personal recommendation (my mother’s neighbour). Marc was very accommodating in setting up the appointment and the fact that my mother is not comfortable with people in her home. Sapphire, the technician, turned up on time and set to work immediately on servicing the boiler. We hardly noticed she was there and upon completion she explained what she had done and how we should pay. This worked extremely well for us, the boiler is now safe for the winter and my 94 year old mother remained totally unstressed by this process.
