Commercial cavity wall insulation for Larne properties

Larne is among the towns we cover in County Antrim, alongside Carrickfergus, Newtownabbey and Belfast. It is around 18 miles north of Belfast.

Blocks of flats in Larne are surveyed as a whole, because the cavity runs across every flat in the building. For commercial buildings in Larne, the survey also considers building use and fire requirements before a material is specified.

Exposure matters for every cavity wall. Parts of County Antrim 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.

On compliance, in Larne 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.
