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.

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
