Cavity wall suitability survey for March properties
Our Cambridgeshire coverage takes in March (PE15) and nearby Wisbech, Ely and Peterborough. It is about 24 miles north of Cambridge.
Buyers and sellers in March often book this check when a survey report or EPC raises questions about the walls. Every inspection point in March is photographed and logged, so you have a record to show a buyer, lender or contractor.
Before any material is chosen, exposure is checked. Much of Cambridgeshire 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 March 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.

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.
