Happy Heating are a fantastic company
Lauren visited our home when our boiler completely broke and we needed a new boiler. She talked me through everything we needed and explained everything about the products.
Jamie was our boiler installer and I can’t thank him enough he went above and beyond to fit our new boiler and hive heater all in one day.
All rubbish was removed when Jamie left and there was no mess anywhere Happy Heating did a fantastic job and I would highly recommend them if you need a new boiler or just a repair or service.

Hi Andrea,
Thank you so much for taking the time to leave such a wonderful review.
We’re delighted to hear that Lauren was able to guide you through the options and explain everything clearly. We know that having a boiler break down can be stressful, so making the process as straightforward and hassle-free as possible is always our goal.
We’ll also be sure to pass your kind words on to Jamie. He takes great pride in his work, and we’re pleased to hear that the installation, Hive setup, and overall service exceeded your expectations. Leaving every home clean and tidy is something we feel is just as important as the installation itself.
Thank you again for choosing Happy Heat and for recommending us. It was a pleasure helping you, and we’re always here should you need any servicing, maintenance, or advice in the future.
Kind regards,
Martin, Lauren & The Happy Heat Team 🔥🏠

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!

Hi Dionne,
Thank you so much for taking the time to leave such an amazing review. Reading comments like yours genuinely means a lot to us.
We’re delighted Lauren was able to get to you quickly when you were left without hot water and help you explore all of the available options. We strongly believe in giving honest advice and helping our customers make the right decision for their home, so it’s wonderful to hear that came across during your experience.
It was a pleasure installing your new boiler and Hive controls, and we’re especially pleased to hear you’ve noticed such a difference in both the warmth of your home and the efficiency of your heating system. Knowing you’re now more comfortable and potentially saving money on your energy bills is exactly why we do what we do.
Thank you for your kind words about both Lauren and the installation team. As a family-run business, we take great pride in providing a friendly, personal service from first visit to final handover.
Your recommendation means the world to us. If we could give customers 6 stars too, you’d certainly get them for being such a pleasure to work with!
Warm regards,
Martin, Lauren & the Happy Heat Team 🔥🏠

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
