Existing insulation and guarantee check for Southall properties

Southall is among the towns we cover in Greater London, alongside Greenford, Heston and Hayes. It is around 11 miles west of London.

Buyers and sellers in Southall often book this check when a survey report or EPC raises questions about the walls. Every inspection point in Southall is photographed and logged, so you have a record to show a buyer, lender or contractor.

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