Cavity wall suitability survey for Preston properties

If your property is in Preston or the PR1 district or nearby Leyland, Chorley and Blackburn, it is within our Lancashire coverage. Preston is one of the main towns we cover in Lancashire.

A survey in Preston gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Buyers and sellers in Preston often book this check when a survey report or EPC raises questions about the walls.

Exposure matters for every cavity wall. 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 Preston 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.

Cavity wall suitability survey in Preston: questions

Is my Preston 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.

Do you cover Preston?

Yes. Preston and the PR1 postcode district are within our Lancashire coverage, along with nearby Leyland and Chorley.

Is the survey free in Preston?

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

Which building regulations route applies in Preston?

Preston is in England, so filling a cavity is notifiable building work and needs a building notice or competent-person self-certification. We confirm the route in writing on your quote.
