Q&A with the experts

Keeping the heat in: Thermal efficiency in older buildings.

Older buildings can be harder to keep warm, and it’s not always clear what improvements will work best or what changes are allowed.

This webinar, held on Tuesday, 17th February 2026, opened with an overview of practical retrofit strategies for older buildings.

Daniel Ayre, Historic Environment Team Leader at Winchester City Council, then explored how traditional buildings were constructed, and what that means for upgrades, retrofitting and planning considerations today.

The heart of the webinar was an open, interactive Q&A with Stuart Mills, lead retrofit adviser at WinACC for our My Home Made Better service.
