Blown mineral wool insulation for Catford properties

If your property is in Catford or the SE6 district or nearby Blackheath, Greenwich and Beckenham, it is within our Greater London coverage. It is around 6 miles south-east of London.

Where a Catford property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. Most Catford 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 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 Catford 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.
