Cavity wall work in Armagh

We cover Armagh and the BT61 postcode district, including nearby Portadown, Craigavon and Lurgan. It is roughly 11 miles south-west of Craigavon.

Every elevation is judged on its own exposure. Parts of County Armagh 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.

For regulations, in Armagh 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.
