Loft insulation for Salisbury properties

We cover Salisbury and the SP1 postcode district, including nearby Trowbridge, Chippenham and Swindon. It is about 34 miles south of Swindon.

Where a Salisbury home also has empty cavity walls, we can survey those at the same time. In Salisbury homes this is often done on the same visit as a cavity fill, which saves a second trip.

In terms of approvals, if cavity wall insulation follows in Salisbury, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
