About the Company

  • At Heat Geek, we are tackling one of the UK’s biggest carbon contributors: home heating.
  • Nearly 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.
  • We have already prevented over 1,000,000 kg of carbon from entering our atmosphere as of January 2026, and we aren’t 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 need passionate, talented, hard working people to be a part of this journey.

Equal Opportunity

  • 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.
  • Even if you don’t tick every box listed above, but are passionate about the work that we are doing and believe that you can make a positive impact here, we’d love to hear from you.
