Harrow is sprawling 1930s semi-detached suburbia — the classic UK property for EWI. Stanmore and Pinner have larger detached Tudor-revival homes; central Harrow has post-war infill where loft and cavity insulation usually take priority. 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.
