Recognised by our peers
Proud Members of the Guild of Master Heat Engineers
The Guild of Master Heat Engineers is unlike any traditional accreditation scheme.
Rather than relying solely on exams or checklists, membership is based on peer recognition from some of the UK’s most respected heating engineers.
Inspired by the medieval guilds, where master craftsmen earned recognition from fellow masters, the Guild exists to help homeowners identify engineers who demonstrate exceptional technical knowledge, workmanship and an ongoing commitment to learning.
Being featured within the Guild means our work and professional standards have been recognised by experienced engineers who understand what good heating design and installation should look like.
For our customers, that’s another level of confidence that you’re choosing an engineer committed to quality, not shortcuts.

Here’s what local customers have to say about their experience with The Heating People.
Taking the guesswork out of heating design
Tired of the one-size-fits-all approach to boiler installation? So are we.
In the past, the physical size of your property and the number of radiators you had, was the only thing used to determine boiler size. And unfortunately, you’ll probably still find a lot of heating engineers using this crude method! But this is inaccurate. It wasn’t the right way to do it in the past. And it isn’t the right way to do it now.
Thankfully, you won’t find any of our engineers counting radiators. We install boilers and heat pumps the right way, following the industry standard (Part L of the Energy Efficiency Regulations). Our tailored service uses scientific calculations to match you with the perfect heating system for your home and lifestyle.
The Heating People are part of the Heat Geek Elite, and carry out heat-loss calculations as standard. We will calculate and recommend the most energy-efficient options for you. This will save you money, whilst helping you to reduce your carbon footprint.
We have over twenty years of experience in helping families with their heating and we provide outstanding quality workmanship alongside exceptional customer service.
