What We Do

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!

Join Us!

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. – And we need passionate, talented, hard working people to be a part of this journey.

Your Mission

At Heat Geek, our ambition is to deliver a best in class customer experience - every homeowner and installer should feel genuinely looked after from the moment they sign up to long after their heat pump is running smoothly.

• Gathering customer insights
• Driving process improvements to prevent recurring issues
• Identifying installer and customer pain points

This is a hands‑on role with real ownership — you’ll see the direct impact of your work in the satisfaction of customers and installers alike. If you care deeply about getting things right for people, are curious about how systems work, and thrive in a fast‑moving startup environment — we’d love to meet you.

If you’re reading this and it resonates with you, we know that you are talented and could do this work anywhere. But we want you to do it HERE, with us, because we need persevering teammates who care about making a real difference in the world.
