Loft insulation for Barnes properties

Barnes sits in Greater London, around 6 miles south-west of London. We work across the SW13 district, including nearby Chiswick, Putney and Fulham.

In Barnes homes this is often done on the same visit as a cavity fill, which saves a second trip. We check ventilation as carefully as insulation in Barnes homes, because both matter for keeping a house dry.

In terms of approvals, if cavity wall insulation follows in Barnes, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.
