Loft insulation for Potters Bar properties

We cover Potters Bar and the EN6 postcode district, including nearby Borehamwood, Hatfield and Cheshunt. It is about 7 miles south-east of St Albans.

We check ventilation as carefully as insulation in Potters Bar homes, because both matter for keeping a house dry. In Potters Bar 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 Potters Bar, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
