Cavity wall insulation for landlords for Farnham properties
If your property is in Farnham or the GU9 district or nearby Godalming, Camberley and Guildford, it is within our Surrey coverage. It is roughly 10 miles west of Guildford.
Blocks of flats in Farnham are surveyed as a whole, because the cavity runs across every flat in the building. For landlords and managing agents in Farnham, we survey in batches and return a result sheet and fixed price per address.
Wind-driven rain is the first thing the surveyor weighs up. 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.
In terms of approvals, in Farnham 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.

How we work with portfolios
One contact, one schedule. We survey in batches, return a simple sheet per address, and book installs around your tenants. Access arrangements and tenant notices are handled with your agent if you prefer.
