Heat pump questions in Cardiff
- How many heat pump installers are there in Cardiff?
- 6 MCS-certified firms are based in Cardiff itself, and 2 more across the rest of Cardiff and the Vale of Glamorgan will usually travel to quote. Heatforce (Wales) Ltd is the most reviewed locally with 564 Google reviews.
- Can I get the Boiler Upgrade Scheme grant in Cardiff?
- Yes. Cardiff is in Wales, where the Boiler Upgrade Scheme gives £7,500 off an air-to-water or ground source heat pump (£2,500 off air-to-air, £5,000 off biomass). Your MCS-certified installer applies and deducts it from the quote, so you never handle the money. Homes off the gas grid heated by oil or LPG get £9,000 between 21 July 2026 and 31 March 2027.
- Should I use a Cardiff installer or one from elsewhere in Cardiff and the Vale of Glamorgan?
- A local firm is easier to get a survey from and quicker for aftercare, but pricing is set by the job, not the postcode. Get a quote from at least one Cardiff installer and one from elsewhere in Cardiff and the Vale of Glamorgan, and make sure both are Boiler Upgrade Scheme registered if you want the grant deducted.
- Do I need an EPC to get a heat pump grant in Cardiff?
- 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.)
