Loft insulation for Brighton properties

Our East Sussex coverage takes in Brighton (BN1) and nearby Hove, Rottingdean and Seaford. Brighton is one of the main towns we cover in East Sussex.

We check ventilation as carefully as insulation in Brighton homes, because both matter for keeping a house dry. Where a Brighton home also has empty cavity walls, we can survey those at the same time.

As for paperwork, if cavity wall insulation follows in Brighton, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
