How to make older homes more energy efficient

If you’ve been wondering how to make older homes more energy efficient, this webinar is for you.

Keeping the heat in: Thermal efficiency in older buildings.

Sometimes it’s unclear what improvements will work best on older buildings. They can be harder to keep warm, and you also need to consider 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.
