Cavity wall insulation for flats for Chelsea properties
We cover Chelsea and the SW3 postcode district, including nearby Battersea, Fulham and Pimlico. It is around 2 miles south-west of London.
Blocks of flats in Chelsea are surveyed as a whole, because the cavity runs across every flat in the building. Work on Chelsea rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer.
Before any material is chosen, exposure is checked. Much of Greater London sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
On compliance, in Chelsea 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.

Fire and height
For blocks, the material must suit the building's height and use. Non-combustible mineral wool is the usual choice; we confirm the system and its certificate limits in writing.
