Your long-term facilities management partner
Managing large facilities requires a heating partner you can truly rely on, not just for a one-off fix, but for dependable, long-term support. At Happy Heat, we aim to be exactly that, your trusted experts for everything from emergency call-outs to proactive, continuous maintenance.
As a family-run business, we bring a consistent, friendly approach to every site visit, which genuinely helps build rapport with your site teams and staff. For absolute peace of mind in any environment, every professional we dispatch is DBS Enhanced checked.
"Happy Heat took over looking after our heating system from British Gas. Best decision we ever made. They are always on the end of the phone with good advice and practical solutions. As with all heating and boiler issues a quick and reliable service is what you need and that is exactly what you get from Happy Heat. Would definitely recommend them to anyone needing a boiler service or new installation. Excellent service at reasonable prices."
Sylvia Smith from Stephen Austin

"Have used many boiler / gas tradesmen in my life, and so happy to have finally used ones who I can so highly recommend. Had quotes for work done both in my office and at home, and the difference was astonishing. They are here to give you the best job, friendly service, and so professional, all for fair and extremely competitive prices. 5 stars plus for Happy Heat."
Alex from CH. Hausmann & Co.

It starts with a chat
Give us a ring and we'll quickly ask a few questions to diagnose the problem. If it's something simple, like low pressure, we'll help you fix it right there on the phone!
We'll book you in
If the phone fix doesn't cut it, don't fret! We'll schedule a visit to track down the gremlin living in the boiler to get that heat flowing again!
"Super-thankful for an excellent job at our church. Thoughtful, friendly, hardworking, problem-solving, optimistic and great fun. Highly, highly recommended!"

10-year warranty with all new Vaillant boiler installations
"We knew Martin from his visits as a British Gas engineer, who was always cheerful, helpful and friendly. When British Gas removed their care plans it seemed an obvious move to get Martin’s company to provide this for us instead. He now not only looks after our care plans (for three different boilers, located across our site), but is also our go to engineer for any gas work we need doing. Recently completing all the pipe work etc needed to remove a superfluous gas meter. He is always happy to advise, and work around our availability, I would not hesitate in recommending him to others."
Vicky from St Paul's Church
