Very professional company - fantastic work carried out

Heat Tech installed a new Vaillant boiler for us. Following a site visit, their initial quotation was issued very quickly, was in a clear format with various options available, and was very reasonable. We were able to book in the work very quickly. The young lady who carried out the work was excellent. She was very knowledgeable, polite and professional. My wife, in particular, was mightily impressed that a woman carried out the work! After the installation, we noticed that some air had built up in the radiator system, which we understand is quite normal when a new boiler is installed. Heat Tech returned very quickly to release the air etc. They also registered our guarantee for us directly with Vaillant. All in all, we are very happy indeed with the service offered by Heat Tech.

Many thanks to Mark for his extremely prompt and efficient service. Following a boiler breakdown we were visited by 0900 and the fault (a broken fan) quickly identified. A replacement part was speedily obtained and by 1100 hrs the boiler was back in operation. I would heartily recommend Heat Tech!

Mark's team had to switch out old boiler set up with loft tanks etc and replace with combi plus some extra rads. A big job that took all week for 2 people. Job completed as planned and all done efficiently. We had a few snagging problems but Mark made sure that one of his team came out to fix them quickly. Have used Mark before and will definitely use him again. Reliable service and good at diagnosing tricking problems!

I remain grateful to Mark for somehow squeezing me into his busy schedule at short notice when our gas boiler broke down last week. But equally appreciative of the highly efficient, thoroughly professional service received. Would definitely recommend.

Heat Tech services (Mark) installed a new boiler for me in the summer, which was done very efficiently. In September we started to have problems with the hot water as the new boiler kept cutting out. Mark couldn't have been more helpful in identifying the problem (failing Shunt Pump) and fixing it. He ensured that we weren't left with a problem. I wouldn't hesitate to use his services again.

Having not used this trader before, I was very impressed with the service provided and would highly recommend them. I needed someone to repair my toilet cistern as it was constantly trickling through the pan. They contacted me quickly to arrange my appointment and confirmed it in an email with details as to who to expect the following day. Neil came out as planned and fixed the problem. Excellent service.

What a brilliant service. Same day response (within hours). Mark came diagnosed the problem immediately and boiler parts were replaced within 2 hours. Very pleased with price charged. This is the first time we’ve used Heat Tech and we were really impressed by Mark’s depth of knowledge, professional approach and attitude. Sarah also was extremely helpful when taking our call. Can’t recommend highly enough.

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.

Really helpful. Excellent advice and service. We had a problem with the flow of cold water in our bathroom after we had left a tap on which resulted in our sink overflowing. I got in touch with Mark following a recommendation of a neighbour. He got back to me quickly and we spoke on the phone. He analysed what the problem probably was and resolved the problem.

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.

Neil and Ethan were on time, polite, informative, considerate and entirely professional. I cannot recommend Heat Tech enough. This is the third time I have had need of their services for different issues and each time they have worked efficiently, solved problems and not been too expensive. All of the staff that I have met have been an absolute credit to Mark who seems to run the business like a well-oiled machine. Thanks so much.

We've had a number of tradesmen, builders, etc. doing various bits on our house over the past few years, and more often than not we've been let down. Not so with Heat Tech! They came to do the job quickly and went above and beyond to make sure it was done properly. I wish everyone cared as much about delivering great service as Heat Tech does!

Kieran from Heat Tech serviced our boiler. He was prompt, polite, tidy and observed Covid guidelines. I appreciated receiving an email reminder that the service was due, along with confirmation of the appointment and email invoice to pay by Direct Debit. This is the second year I have used Heat Tech for my boiler service and expect to use them again the future.

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)
