Loft insulation for Deeside properties
We cover Deeside and the CH5 postcode district, including nearby Hawarden, Buckley and Flint. It is roughly 11 miles north of Wrexham.
Where a Deeside home also has empty cavity walls, we can survey those at the same time. In Deeside homes this is often done on the same visit as a cavity fill, which saves a second trip.
As for paperwork, if cavity wall insulation follows in Deeside, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.
