Cavity wall suitability survey for Islington properties

Islington sits in Greater London, roughly 2 miles north-east of London. We work across the N1 district, including nearby Highbury, Holloway and Camden Town.

Buyers and sellers in Islington often book this check when a survey report or EPC raises questions about the walls. The written result for your Islington property is plain English: what we found, what it means and what, if anything, to do next.

Every elevation is judged on its own exposure. 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 Islington 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.
