Sutton, Cheam and Carshalton are dominated by 1930s semi-detached homes — the classic UK property type for EWI. Most have suspended timber floors that benefit hugely from underfloor insulation, and lofts that need topping up to current 270mm standards. The right choice depends on your wall construction (solid vs cavity), property age, and whether external alterations are permitted. Our free survey identifies the most cost-effective option for your specific home.

Yes. As a TrustMark and PAS2030-19 certified installer we can deliver work funded under ECO4 and the Great British Insulation Scheme (GBIS) for eligible households. Local authority and council-led schemes also occasionally apply in Greater London.
