Loft insulation for Swanley properties
Swanley sits in Kent, roughly 17 miles north-west of Maidstone. We work across the BR8 district, including nearby Dartford, Sevenoaks and Gravesend.
We check ventilation as carefully as insulation in Swanley homes, because both matter for keeping a house dry. In Swanley homes this is often done on the same visit as a cavity fill, which saves a second trip.
For regulations, if cavity wall insulation follows in Swanley, 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.

What we check
Existing depth and condition, ventilation at the eaves, water tanks and pipes that need insulating, downlighters that need covers, and storage boarding that needs raising so insulation is not crushed.
