Loft insulation for Dartford properties

Dartford sits in Kent, about 18 miles north-west of Maidstone. We work across the DA1 district, including nearby Swanley, Gravesend and Strood.

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

For regulations, if cavity wall insulation follows in Dartford, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
