EPC Score Impact
+5 to +10 points
Loft insulation is one of the most cost-effective energy efficiency improvements. By adding or topping up insulation in your loft space, you can significantly reduce heat loss through the roof. Most homes lose around 25% of their heat through an uninsulated roof. The installation is straightforward and typically completed within a day. Government grants are often available through the ECO scheme for qualifying households.
Government funding may be available
The ECO4 scheme and Great British Insulation Scheme may cover the cost of loft insulation for qualifying households — free of charge.
