About us

Warmur is on a mission to accelerate home decarbonisation by making it easy for everyone to start that journey today. We help households get the most impactful energy and carbon saving measures for their budgets and circumstances. We’re building an innovative technology platform to help households visualise the effects of whole-home electrification, and help installers to streamline the process from contact with the customer to contract-ready jobs.

Our technologies are designed to take the pain out of the heating installation lifecycle, from decision making, through installation, to ongoing monitoring and support. Our core platform provides tools to make the process easier for both householders and heating engineers, including home energy modelling, customer and installer portals and APIs, and AI support tools tuned to provide practical advice around home heating.
