Cavity wall suitability survey for New Malden properties
If your property is in New Malden or the KT3 district or nearby Surbiton, Morden and Wimbledon, it is within our Greater London coverage. It is about 9 miles south-west of London.
Buyers and sellers in New Malden often book this check when a survey report or EPC raises questions about the walls. Every inspection point in New Malden is photographed and logged, so you have a record to show a buyer, lender or contractor.
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.
For regulations, in New Malden 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.
