Grant and funding check across Dyfed
We cover 6 towns in Dyfed, including Llanelli, Ammanford, Carmarthen, Aberystwyth, Haverfordwest and more.
Funded schemes in Wales open and close through the year, so we check what is running now rather than relying on old leaflets. If a Dyfed household does not qualify, you can still have a free survey and a fixed private price, with no obligation.
Building Regulations in Wales
In Wales, filling an existing cavity is also notifiable building work under the Building Regulations as they apply in Wales. A registered installer normally self-certifies it through a competent person scheme; otherwise a building notice goes to your council's building control before work starts. Welsh rules can differ from England's, so the notification route is confirmed in writing on your quote.
Funding in Wales
- Warm Homes Nest offers free improvements, including insulation, to eligible low-income owner-occupiers and private renters; eligibility was widened to some households without means-tested benefits.
- Green Homes Wales has been piloting advice and interest-free loans for households above the Nest and ECO4 income thresholds.
- ECO4 runs until 31 December 2026 across Great Britain, including Wales.

If you do not qualify
On a suitable wall, the Energy Saving Trust says most households recoup the cost of cavity wall insulation within about five years, and installing it in a home is currently zero-rated for VAT. We give a fixed price after a free survey.
