Blown mineral wool insulation for Slough properties
If your property is in Slough or the SL1 district or nearby Windsor, Maidenhead and Bracknell, it is within our Berkshire coverage. It is around 17 miles east of Reading.
Slough properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. Most Slough houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.
Wind-driven rain is the first thing the surveyor weighs up. Much of Berkshire 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 Slough 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.

When is it not the right choice?
Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.
What is included in Slough
- Cavity barriers where needed
