Cavity wall suitability survey for Nelson properties

Our Lancashire coverage takes in Nelson (BB9) and nearby Colne, Burnley and Accrington. It is about 21 miles east of Preston.

The written result for your Nelson property is plain English: what we found, what it means and what, if anything, to do next. A survey in Nelson gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

Before any material is chosen, exposure is checked. Parts of Lancashire 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.

As for paperwork, in Nelson filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

What the surveyor checks

Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.

Cavity wall suitability survey in Nelson: questions

Is the survey free in Nelson?

Yes when it is for an install quote. Standalone reports for Nelson buyers, sellers or landlords who do not need an install quote are priced before you book.

Is my Nelson home too exposed for cavity insulation?

Parts of Lancashire 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.

Is there VAT on a cavity wall survey in Nelson?

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.

Do you cover Nelson?

Yes. Nelson and the BB9 postcode district are within our Lancashire coverage, along with nearby Colne and Burnley.
