Boiler service and timer replacement
Customer Service
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.

Thank you so much
Brilliant. We had no water. We called Mark. Within 2 hours he sent a lady plumber and her assistant. She found the problem, went out to buy a spare part, returned, and all was completed, with running water from all taps and showers working again much faster than I thought - just 90 minutes. This is definitely a company I will recommend.

Excellent Service
Customer Service
The email the day before reminding me that the Service was due to be carried out was very helpful and assuring. The Engineer, Ian, arrived on time and carried out a full Service within the schedule and budget. No hidden extras. Ian was extremely pleasant and approachable and a pleasure to deal with. I have no hesitation in calling on the services of this Company for any future problems that may arise.

Rare Nowadays
Customer Service
Tap started leaking - Heat Tech Responded quickly - Efficiently and fair price. I continue to spread the word for this company, they well deserve the business. He once came out on a Saturday night 6.00pm and fixed a leak for me. They put the customer first - a bit of a rarity today!

Great diagnosis and work
Customer Service
Mark came out to my house and fixed something my my heating very quickly and well. I asked him to diagnose a water pressure issue which I’d had a quote on from another contractor and he gave me a much better solution which was very cost efficient. The team did a great job of this - awesome to meet a female plumber also!

Speedy and efficient service
Customer Service
Many thanks to Sapphire and the team for the speed and efficiency of rerunning gas pipework following leak. Having anticipated being without gas for weeks, Heat Tech had me up and running in days. They kept me informed throughout. Punctual and courteous.

Power Flush
Customer Service
I called Heat Tech and spoke to a very nice person called Sarah who explained Mark the engineer would be calling me back to ask a few questions about what was needed as my radiators were not working sufficiently. Mark called back and we discussed the procedure for a power flush for my heating system, which is 30 years old, so I wasn’t expecting miracles but that’s what I got. The job was booked in and two very professional guys called Neil and Lewis arrived, very polite and easy to talk to and they started the job. I also had to have a new circulation pump fitted. The guys worked hard as my rads were very gumped up but that didn’t bother them they cleared them and my radiators are working brilliantly. I was chuffed and so pleased I’ve found Heat Tech and will be definitely using them again. It’s was so refreshing to have the work carried out so professionally by experienced people. A big thank you to the Heat Tech Team from start to finish.

First Class again
Customer Service
Heat Tech installed my boiler with other works in March 2012. They have serviced my boiler installation ever since and always carry out a first class job at a very reasonable price. Their general plumbing is also of a high standard. Great, reliable service. 100% recommended.
