Cavity wall suitability survey for Purley properties
Our Greater London coverage takes in Purley (CR8) and nearby Coulsdon, South Croydon and Wallington. It is about 12 miles south of London.
A survey in Purley gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Buyers and sellers in Purley often book this check when a survey report or EPC raises questions about the walls.
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 Purley 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.
