Martin arrived on time did a boiler service, replaced gas pipework for new hob and issued a gas safety certificate. Work done in a reliable tidy fashion and reasonably priced. Will use again.

Huge shoutout to Happy Heat for saving the day (and my sanity)! 🔥 They came out today to fit a brand new boiler and thermostat, and honestly… I’m almost excited for cold weather now. Almost. 😄

From start to finish, the service was spot on — friendly, professional, and no messing around. They explained everything in plain English (no confusing jargon), worked efficiently, and left everything clean and tidy. Bonus points for being genuinely lovely people too!

The new setup is working perfectly, and I can already tell it’s going to make a big difference. Warm house, happy me!

If you’re thinking about getting your boiler sorted, don’t even hesitate — Happy Heat absolutely nailed it. 👏🔥

If I could give 6 stars I would

If I could give 6 stars I would. Amazing service, Lauren had attended my house before for a quick job but this time when my water went cold at 8am, she was round within 2 hours. She gave me all the options and her honest recommendations, ended up getting a new boiler and best price I could find, including the high tech Hive installation and this power couple came bright and early, service with a smile, talked me through everything and didn't even know my house could be this warm and I'd been suffering and running up my bills for years. Can't recommend enough!

My elderly mother had a huge problem…

My elderly mother had a huge problem with her combi boiler on a Sunday evening leaving her with no hot water I called the company that evening and they answered the phone straight away.They came out early the next morning .Lauren who came out fixed the problem and went out of her way phoning around suppliers to pick up another part that we didn't expect that was needed and came straight back.As she new my elderley mother couldn't be without hot water.I felt she went above and beyond to make sure my mother had the hot water she needed.Besides being reassuring and professional their rates are very reasonable,I wouldn't hesitate to reccomend Happy Heat to anyone

I got several quotes for the job

I got several quotes for the job. Happy Heat were considerably cheaper than the others. I took a chance and it paid off.
Martin was very professional and efficient. He showed me another problem I had indirectly with the job. He repaired this at no extra cost.
I highly recommend this company and I will look no further if I need a plumber again. Cheers to Happy Heat

Massive thank you to happy heat

Massive thank you to happy heat. Awesome service, kind of last minute but they were happy to help for a new boiler fitting heading into winter as it wouldn’t have been good with our old one packing in. Pukka job.

5 stars plus

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

Hello Kit, Thank you for reviewing the service you received from Happy Heat 😊🙌

Rated 5 out of 5 stars

Great service - thank you

Martin and his team were very professional and reliable in the work they have done for us so far. We are glad to have picked them as our new service provider.
Martin is not the type of engineer that will do the bare minimum but more the kind of person that will go the extra mile to help you. Very knowledgeable and a friendly, considerate attitude.
