Cavity wall suitability survey for Morden properties

Our Greater London coverage takes in Morden (SM4) and nearby Mitcham, Wimbledon and Carshalton. It is about 8 miles south of London.

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

Local weather affects which walls can be filled. 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.

In terms of approvals, in Morden filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

Cavity wall suitability survey in Morden: questions

Which building regulations route applies in Morden?

How soon can you visit in Morden?

We arrange dates when you get in touch. Availability varies through the year, so we give you real dates rather than a promise on the website.

Is there VAT on a cavity wall survey in Morden?

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 Morden 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.
