That’s how many homes need retrofitting between now and 2050 if the UK is going to meet its energy efficiency goals.
The challenge isn’t just carrying out the work. It’s knowing where to start, which homes need attention first, and whether retrofit projects are actually delivering the results they’re supposed to.
Lucy Lyons, Co-Founder and CEO of Kestrix and a Forbes 30 Under 30 honouree in 2024, joins us on the UK Construction Podcast to explain how her company is using drones, thermal imaging, and AI to create what she describes as the “Google Maps of heat loss”. By turning aerial data into detailed 3D models, the platform helps housing providers identify heat loss, prioritise investment, assess retrofit opportunities, and measure outcomes across thousands of properties.
The conversation explores social housing, EPC assessments, retrofit funding, AI in construction, energy efficiency, and the role technology could play in helping the UK tackle one of its biggest infrastructure challenges.
