Existing insulation and guarantee check for Peckham properties

Our Greater London coverage takes in Peckham (SE15) and nearby Brixton, Greenwich and Catford. It is about 3 miles south-east of London.

Buyers and sellers in Peckham often book this check when a survey report or EPC raises questions about the walls. A survey in Peckham gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

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.

On compliance, if cavity wall insulation follows in Peckham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

How to tell if a house already has cavity insulation

Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
