HEH replaced my boiler 12 years ago and have been servicing it ever since. It was done this morning. The engineer was very polite and helpful.

Great service as always. Contacted on the web over the weekend had a response the same weekend to confirm attendance the afternoon of the next working day They attended and couldn't rectify, requiring a Worcester bosch engineer. They arranged for Worcester to contact us, which they did in an hour Excellent service recommended

Under floor heating

I used HEH to move the boiler and to install under floor heating at the same time as part of a garage conversion. Work needed to be carried out urgently. Even though the job was quoted for 4 days they did it over 3 days by sending more man power so they could squeeze me in. Work was carried out to an exceptional standard and when they could have upselled even though it was not needed, they did not. If you are looking for a trustworthy firm who will come in and do the job to a high standard and not charge more then what is required then use HEH.

I have used HEH for many years and have always been impressed by the quality of the service provided by this local family run company. We had a new boiler fitted, the guys were exceptional from start to finish, polite, efficient and very professional. All completed with minimal disruption, I can highly recommend this company wouldn’t use any one else. ⭐️⭐️⭐️⭐️⭐️

Dave & his assistant replaced 2 radiators for us. They arrived on time, were very pleasant. They worked hard & were extremely tidy. On a positive note they noticed a mark on one of the radiators & insisted that it wasn’t acceptable & will replace it as soon as possible. We have used this company many times & would definitely recommend them.

I have use HEH for years for my boiler service. Have been meaning to replace my thermostat since I moved into a new property and asked if they could provide this service. They could, and as usual it was a brilliant job. I was messaged when they were on the way. The chap who completed the job was friendly, informative and undertook the job efficiently. He respected my house and was very considerate of the cat! Thanks again for great work.
