Commercial cavity wall insulation for Purley properties

If your property is in Purley or the CR8 district or nearby Coulsdon, South Croydon and Wallington, it is within our Greater London coverage. It is roughly 12 miles south of London.

Blocks of flats in Purley are surveyed as a whole, because the cavity runs across every flat in the building. Per-address photo records for Purley properties make compliance files and EPC updates straightforward.

Before any material is chosen, exposure is checked. 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 the rules side, in Purley 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.

What is different on commercial jobs

Access is planned around opening hours, often with towers or MEWPs. Material choice takes account of building use and fire requirements, so non-combustible mineral wool is often specified. Work is usually standard-rated for VAT unless the building qualifies for a relief, which we confirm on the quote.
