Party wall cavity insulation for Peckham properties

We cover Peckham and the SE15 postcode district, including nearby Brixton, Greenwich and Catford. It is roughly 3 miles south-east of London.

Most Peckham houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. For semi-detached and terraced homes in Peckham, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.

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.

On the rules side, in Peckham filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

What we need from you and your neighbour

The cavity is shared, so we talk you through notifying your neighbour before work. Filling is done from your side, usually through the loft. The survey confirms the wall is a cavity wall and not solid masonry, and checks for cables, flues and any gaps that would let fill escape.
