Commercial cavity wall insulation for Horsham properties

Horsham is among the towns we cover in West Sussex, alongside Crawley, Haywards Heath and Burgess Hill. It is about 7 miles south-west of Crawley.

Work on Horsham rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer. Blocks of flats in Horsham are surveyed as a whole, because the cavity runs across every flat in the building.

Exposure matters for every cavity wall. West Sussex has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

For regulations, in Horsham 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.
