Identification and stopping of leak
Customer Service
We had a leak somewhere under the kitchen floor but did not know what it was. We were unable to turn the water off. Mark arrived when he said he would and found the problem. We were delighted that he managed to fix the leak without taking up the floor despite the fact that this meant he had to work in a small and uncomfortable space. He cleaned up thoroughly, including taking out some broken concrete rubble left by a previous contractor. Clearly, we are very pleased!

Leaking tap
Customer Service
Our tap had been leaking, vibrating and humming for a while. I called Mark from Heat Tech at a neighbours recommendation and am really impressed with the service we received. The team were over to replace our tap sooner than originally discussed and were knowledgeable and efficient. The team were covid secure, which was reassuring. Very happy with this company and will be using for any future work.

Terrific Experienced Advice
I had an issue with my boiler/heating system that my UW engineer could fix and he advised an expensive power flush. 5 minutes on the phone to Heat Tech Service and they had the issue pin pointed to a pump. They gave me great confidence if I cant resolve this through my insurance I will willingly use them.

Fast response
Customer Service
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.

Quality work, a pleasure to deal with
Customer Service
Mark was recommended to me in 2019 and since then he has carried out a variety of jobs for me, including boiler service and repair, replacement shower and leaking taps. Mark has a very competent team who are easy to deal with and get on with the job - really good value for money.

Boiler not working no hot water
Customer Service
Extremely happy and very impressed with Heat Tech Services. We rang this company on a Sunday afternoon and Mark from Heat Tech arrived the next day, early Monday morning. Mark was professional & very knowledgeable. Our problem with our boiler was resolved and have also used heat tech services to service our boilers. This was completed by Marks team who were once again professional, efficient & friendly. Excellent workmanship would highly recommend.

Excellent service
Customer Service
I was lucky enough to be introduced to Mark when I first moved to Rickmansworth in 2014. He and his team had done work for my son, so I had no hesitation in asking him to do some things that were that needed here. He installed a new Combi boiler, with all that that involved, disposing of the old boiler and enormous tank. He also took away an old radiator and replaced it with a new one on the opposite side of the room. Since then, he and his team have regularly serviced the boiler. Mark has an excellent work ethic which he passes on to new members of his team. I have no hesitation in recommending Heat Tech.

Great work, quick response, safely done
Customer Service
Rang one day, engineers came the next day (after sending photos to help diagnose problem before visit). Work carried out carefully and thoroughly, problem solved. Covid-safe practice throughout - keeping distance, wearing masks, etc. Pleasant and polite too. Well done Heat-Tech. A good job at a fair price, as usual
