Cavity wall insulation for flats for Larne properties
Larne is among the towns we cover in County Antrim, alongside Carrickfergus, Newtownabbey and Belfast. It is about 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 landlords and managing agents in Larne, we survey in batches and return a result sheet and fixed price per address.
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.
In terms of approvals, 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.

Fire and height
For blocks, the material must suit the building's height and use. Non-combustible mineral wool is the usual choice; we confirm the system and its certificate limits in writing.
