Underfloor insulation for Ammanford properties
If your property is in Ammanford or the SA18 district or nearby Llanelli and Carmarthen, it is within our Dyfed coverage. It is around 14 miles east of Carmarthen.
We check ventilation as carefully as insulation in Ammanford homes, because both matter for keeping a house dry. In Ammanford homes this is often done on the same visit as a cavity fill, which saves a second trip.
On compliance, if cavity wall insulation follows in Ammanford, 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.

Keeping the void ventilated
Air bricks under a suspended floor must stay clear so the timbers stay dry. Insulation goes between the joists, not across the void, and gaps at skirtings are sealed to stop draughts.
