About the Company
- At Heat Geek, we are tackling one of the UK’s biggest carbon contributors: home heating.
- 20% of all UK carbon emissions stems from home heating – and that contribution is even bigger on a global scale.
- At Heat Geek, we are changing that.
- By simplifying a traditionally complex industry and revolutionising the technology used by installers, we’re making low-carbon heating mainstream.
- As of July 2026 we have prevented 2,600,000 tonnes of carbon from entering our atmosphere, and we're not stopping there!
- People are at the core of who we are and what we do.
- From decreasing homeowners’ energy bills to help with the cost of living, to empowering talented heating engineers to perform outstanding installations, to ensuring a greener world for all of us, we believe in the power of what we can all do together.
- We believe great teams are built from different ways of thinking, learning, and living, and as such, we strive to build an organisation where people can show up as themselves.
