Excellent service
Very reliable company. Always arrives within the agreed window. Good communication. Always professional. I have used this company for several years. Firstly, to install a new boiler, and then for regular servicing, and the service is consistently excellent.

I had a radiator that wasn’t working. The engineer Billy, came early the next morning and sorted it out for me. He is also initiating another job to rectify the thermostat being on the wrong side and having a ‘boiler mate’ fitted for when it freezes so the boiler won’t stop. Brilliant service for a woman living alone. Many thanks.

Outstanding Service We cannot recommend this heating engineering company highly enough. From the very first visit, Andy, the boss, was fantastic. The girls in the office, emails and texts. Andy came out to us, calmly listened to the ongoing issues we were having with our water pressure and temperature, reassured us, and clearly explained two different options for resolving the problem. Everything was explained in detail, with no pressure at all. We were booked in promptly, and on the agreed day Andy arrived on time with Carl, the senior engineer. The work took two days, Jeorge joined the team and throughout the entire job the team were absolutely amazing. Every engineer we dealt with was polite, friendly, professional and clearly took pride in their work. They worked incredibly hard, kept us informed throughout, and went above and beyond to make sure everything was done properly. At the end of each day, they tidied everything up and left the place spotless. It really was a pleasure having such a professional and respectful team in our home. They genuinely couldn't do enough for us, and we are extremely grateful for all their hard work.

I had 7 radiators replaced and from the estimate to the finish, HEH were professional and thorough throughout the whole process. Little things like putting down plastic sheets where they walked through the house make a difference as well as friendly and courteous staff. Would definitely recommend.
