Cavity wall suitability survey for Archway properties

We cover Archway and the N19 postcode district, including nearby Holloway, Muswell Hill and Chalk Farm. It is around 4 miles north of London.

The written result for your Archway property is plain English: what we found, what it means and what, if anything, to do next. Every inspection point in Archway is photographed and logged, so you have a record to show a buyer, lender or contractor.

Wind-driven rain is the first thing the surveyor weighs up. Much of Greater London 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.

For regulations, in Archway 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 Archway: 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.

Is there VAT on a cavity wall survey in Archway?

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 Archway home too exposed for cavity insulation?

Much of Greater London is in the more sheltered driving-rain zones, but exposed and coastal sites are still checked carefully. The survey records the exposure of each wall before recommending a material, or recommending against filling.

Do you cold-call in Archway?

No. We only come out when you have asked us to. If someone cold-calls offering free insulation, check before you agree to anything.
