Loft insulation for Swindon properties

Swindon is among the towns we cover in Wiltshire, alongside Chippenham and Trowbridge. Swindon is one of the main towns we cover in Wiltshire.

We check ventilation as carefully as insulation in Swindon homes, because both matter for keeping a house dry. In Swindon homes this is often done on the same visit as a cavity fill, which saves a second trip.

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