New central heating system

The transition to our new central heating system from our old freestanding boiler was carried out with the greatest care, efficiency, expertise and professionalism we could have hoped for. From Richard’s first visit to completion by Dylan and his team the whole conversion was undertaken to the exact timescale we were given at the outset and with the minimum disruption to our routine. We cannot thank them enough.

I've been with HEH on a service plan for a number of years. Had a new boiler fitted through the company last year. Can't fault or their engineers. Today Billy completed a service. I received a text message to alert me the engineer was on his way. Work was completed to a high standard, he cleaned up after himself, checked all the radiators and even answered some questions about the working of the boiler and adjustments I can make to get the best out of the boiler. Would continue to highly recommend.

I called HEH for a second opinion having been advised that I needed a new boiler. The HEH fitter said the boiler was repairable which he did by replacing the burner seal. He also recharged the expansion vessel. He said the boiler was 12 years old and had a life expectancy of 16 years. The fitter was smart, polite and informative. I regard the service I received as workmanlike and honest. I would definitely return to HEH should I need them in future.

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.

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.

Recommended by my daughter. I made enquiries and had immediate call back and advice. I had a fractured outdoor pipe fixed end of January , and booked a boiler service which was done today. The plumber's are all very polite and and I feel very at ease with them in my home. Work done and no mess. I Will not hesitate recommending this plumbing company
