Existing insulation and guarantee check for Acton properties
If your property is in Acton or the W3 district or nearby Chiswick, Shepherds Bush and Willesden, it is within our Greater London coverage. It is about 6 miles west of London.
Buyers and sellers in Acton often book this check when a survey report or EPC raises questions about the walls. A survey in Acton 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 Acton, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

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.
