Draught-proofing for Barry properties
If your property is in Barry or the CF62 district or nearby Penarth and Cardiff, it is within our South Glamorgan coverage. It is about 7 miles south-west of Cardiff.
In Barry homes this is often done on the same visit as a cavity fill, which saves a second trip. Where a Barry home also has empty cavity walls, we can survey those at the same time.
On compliance, if cavity wall insulation follows in Barry, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.
Funding in Wales
In Wales, Warm Homes Nest offers free improvements to eligible low-income households, and ECO4 runs to 31 December 2026.
Sources: Welsh Government: warmer and more energy efficient homes (July 2026); GOV.UK: extending the ECO4 end date, government response.
Ventilation still matters
Trickle vents, air bricks and extractor fans are there for a reason. We seal accidental gaps, not the ventilation your home needs to keep condensation down.
