Summary

Loft insulation is a relatively straightforward measure to install and can save around 30% of the heat loss from your home, and as much as 20% can be saved from your heating bills as a result.

This equates to £80 – £300 a year on your heating bills. Loft insulation helps to create an even temperature in your home – keeping your home warm in winter and cool in the summer.

Standards for loft insulation have increased since it was first introduced. In 1977 under the first building regulations standards, 25mm (1 inch) was recommended. Current building regulations now recommend 300mm (12 inches) or more, installed into modern new build homes.
