Loft insulation for Daventry properties
Daventry is among the towns we cover in Northamptonshire, alongside Northampton, Market Harborough and Wellingborough. It is roughly 12 miles west of Northampton.
Small measures like this are often among the cheapest per pound saved, and they suit Daventry homes of every age. In Daventry 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 Daventry, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
