Loft insulation for Durham properties

Our County Durham coverage takes in Durham (DH1) and nearby Chester-le-Street, Stanley and Bishop Auckland. Durham is one of the main towns we cover in County Durham.

Small measures like this are often among the cheapest per pound saved, and they suit Durham homes of every age. We check ventilation as carefully as insulation in Durham homes, because both matter for keeping a house dry.

In terms of approvals, if cavity wall insulation follows in Durham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
