Cavity wall suitability survey for Boston properties

If your property is in Boston or the PE21 district or nearby Spalding and Skegness, it is within our Lincolnshire coverage. It is roughly 27 miles south-east of Lincoln.

The written result for your Boston property is plain English: what we found, what it means and what, if anything, to do next. A survey in Boston 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. Much of Lincolnshire sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

As for paperwork, in Boston 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 Boston: questions

Will you tell me if I do not need any work?

Yes. If the findings show nothing needs doing, or a cheaper fix such as clearing a gutter will do, we say so.

Which building regulations route applies in Boston?

Boston 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.

Is the survey free in Boston?

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

Is there VAT on a cavity wall survey in Boston?

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.
