First time I used HEH for our boiler service. I walked into their office inquired about service. We agreed a date for service. Staff efficiently booked engineer appointment. On the day Engineer sent me a text half an hour before he due to come. Bren was very polite and pleasant. He explained about what kind of service he was going to do. He carried out the job very efficiently. Excellent. I would highly recommend HEH to anyone.

Leaking boiler

1st class service again from first call to job completion. Called HEH at 9am this morning to report a leak from our boiler and was given a two hr time frame for the engineer to attend. Also received a text message 10 minutes before the engineer arrived. Part replaced and boiler repaired by 12! Polite, efficient engineer who identified the problem immediately. No waiting for parts as he had them available and no mess. Price for the job brilliant. We would have paid the same just as a call out charge with other providers. We have also used HEH for our annual boiler service for years now and have never had a better service.

I called HEH around 10.30 this morning because of two leaking radiators. About an hour later an engineer turned up to repair them. Fantastic time scale. The engineer was extremely polite and efficient and was totally respectful of my property. Even though he had to go out to his van several times. He put shoe covers on each time he returned. I have used this company for many years and always find their service second to none. I would never have any hesitation is recommending them to anyone.

Replacement Boiler

We have been using HEH for a number of years for services and when the time came for a new boiler we trusted them to do the job. The surveyor came and explained what needed doing and shortly after his visit we received the quote which we happily accepted. On the day of the installation Jack and Dylan arrived on time and confirmed what they were doing. They worked steadily during the day and kept us informed about what was going on. The second morning Josh came to help with the brickwork for the new flue. All the lads were great and they cleaned up after themselves. I can't express how happy we were with the job they did.

I called this company yesterday because my boiler had stopped working, and they managed to send an engineer out first thing this morning. The repair was done quickly and professionally, and the boiler is now working perfectly again. The engineer was friendly, explained everything clearly. Really impressed with how fast and efficient the whole process was — highly recommend!
