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.

I have used HEH for many years and always been impressed by the quality of the service provided by this local family run company. I had my heating breakdown this week due to a faulty fan. HEH were prompt to respond to my phone call, came out to assess and ordered the new fan. This was fitted today and my heating is now back up and running well. All completed within a few days by efficient friendly staff. I can highly recommend this company for all gas services.
