Cavity insulation top-up for Lisnaskea properties

Lisnaskea sits in County Fermanagh, roughly 12 miles south-east of Enniskillen. We work across the BT92 district, including nearby Irvinestown and Enniskillen.

If a wall in Lisnaskea is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. Most Lisnaskea houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.

Wind-driven rain is the first thing the surveyor weighs up. Parts of County Fermanagh 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 Lisnaskea 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.

How do I know if my walls need a top-up?

Cold patches on internal walls, a thermal image showing uneven heat loss, or an EPC that says 'filled cavity' when parts of the house feel colder are all signs. Extensions are a common cause: the new wall is insulated as built, but the old wall it joins may have been left partly empty.
