It's one of those things most homeowners don't think about until the energy bill lands on the doormat. An industry report has put a number on it: around 7.6 million homes across the UK still have completely uninsulated walls, losing heat through them every day. If your Croydon house was built before the 1920s, there's a good chance it's one of them.
What insulating solid walls can do
The report, backed by the external wall insulation industry, says insulating solid walls can cut whole-house heat loss by up to 55%. That means warmer rooms in winter, lower bills month after month, and a home that's simply more comfortable to live in. Yet government attention has shifted heavily towards heat pumps and solar panels, leaving plenty of older properties still leaking heat.
Do it while the builders are in
If you're planning a house extension, loft conversion or major refurbishment in Croydon, this is a real opportunity. When the walls are already open and the scaffold's already up, adding proper insulation is far less disruptive than doing it as a separate job later, and the savings keep coming for years.
The key is working with builders who understand how older houses are put together. Solid walls need to breathe, and the wrong insulation in the wrong place can trap moisture and cause damp. We'll talk you through the sensible options for your house as part of the survey.
