Commercial cavity wall insulation for Coleraine properties

Coleraine sits in County Londonderry, around 27 miles east of Derry. We work across the BT52 district, including nearby Limavady, Magherafelt and Derry.

Per-address photo records for Coleraine properties make compliance files and EPC updates straightforward. Work on Coleraine 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 County Londonderry 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 Coleraine inserting cavity wall insulation needs a building control application to the council before work starts.

Funding in Northern Ireland

In Northern Ireland, the Affordable Warmth Scheme helps eligible households with a gross income under £23,000.

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.
