Cavity wall suitability survey for Coleraine properties

Coleraine is among the towns we cover in County Londonderry, alongside Limavady, Magherafelt and Derry. It is about 27 miles east of Derry.

Buyers and sellers in Coleraine often book this check when a survey report or EPC raises questions about the walls. Every inspection point in Coleraine is photographed and logged, so you have a record to show a buyer, lender or contractor.

Local weather affects which walls can be filled. 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.

Cavity wall suitability survey in Coleraine: questions

Is there VAT on a cavity wall survey in Coleraine?

The survey is free when it is for an install quote. A standalone survey report is not insulation, so it is normally standard-rated for VAT, and the price you are quoted includes it.

Is my Coleraine home too exposed for cavity insulation?

Parts of County Londonderry get some of the heaviest wind-driven rain in the UK, so the survey is stricter and some walls are better left unfilled. The survey records the exposure of each wall before recommending a material, or recommending against filling.
