We cover Crawley and the RH11 postcode district, including nearby Horsham, East Grinstead and Haywards Heath. Crawley is one of the main towns we cover in West Sussex.

Small measures like this are often among the cheapest per pound saved, and they suit Crawley homes of every age. In Crawley homes this is often done on the same visit as a cavity fill, which saves a second trip.

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