Commercial cavity wall insulation for Flint properties

If your property is in Flint or the CH6 district or nearby Deeside, Buckley and Hawarden, it is within our Clwyd coverage. It is around 15 miles north-west of Wrexham.

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

Exposure matters for every cavity wall. Parts of Clwyd face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

In terms of approvals, in Flint filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

Funding in Wales

In Wales, Warm Homes Nest offers free improvements to eligible low-income households, and ECO4 runs to 31 December 2026.

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.
