Cavity wall insulation for landlords for Eltham properties

We cover Eltham and the SE9 postcode district, including nearby Blackheath, Welling and Catford. It is around 9 miles south-east of London.

For commercial buildings in Eltham, the survey also considers building use and fire requirements before a material is specified. For landlords and managing agents in Eltham, we survey in batches and return a result sheet and fixed price per address.

Local weather affects which walls can be filled. 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.

In terms of approvals, in Eltham filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
