Cavity wall insulation for flats for Broadstairs properties
Our Kent coverage takes in Broadstairs (CT10) and nearby Ramsgate, Margate and Deal. It is around 40 miles east of Maidstone.
Blocks of flats in Broadstairs are surveyed as a whole, because the cavity runs across every flat in the building. For landlords and managing agents in Broadstairs, we survey in batches and return a result sheet and fixed price per address.
Exposure matters for every cavity wall. Much of Kent 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 Broadstairs 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.

Why one flat cannot usually be done alone
The cavity runs continuously across the building. The Energy Saving Trust notes that flats need agreement from the whole block. Filling one flat's walls in isolation leaves gaps, and the freeholder normally owns the structure.
