Cavity wall insulation for flats for Esher properties
Our Surrey coverage takes in Esher (KT10) and nearby Walton-on-Thames, Sunbury-on-Thames and Epsom. It is about 13 miles north-east of Guildford.
Work on Esher rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer. Blocks of flats in Esher are surveyed as a whole, because the cavity runs across every flat in the building.
Exposure matters for every cavity wall. Much of Surrey 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 the rules side, in Esher 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.
