- Not any more. Since 28 April 2026 a valid EPC is no longer required to apply for the Boiler Upgrade Scheme. If your home doesn't have one, your installer instead supplies a utility bill or fuel receipt dated within the last three months plus photographs of the existing heating system. (The council-run Warm Homes: Local Grant in England still uses the EPC — it's for homes rated D to G.)
- Can installers from outside Carmarthenshire do my install?
- Yes — most firms travel 25 to 50 miles, so installers in Pembrokeshire, Ceredigion, Powys and Swansea and Neath Port Talbot will often quote in Carmarthenshire too. Distance mainly affects survey availability and aftercare response, so ask where their engineers are based.
