Heat pump questions in Haverfordwest
- How many heat pump installers are there in Haverfordwest?
- 4 MCS-certified firms are based in Haverfordwest itself, and 4 more across the rest of Pembrokeshire will usually travel to quote. Green Warmth Ltd is the most reviewed locally with 24 Google reviews.
- Can I get the Boiler Upgrade Scheme grant in Haverfordwest?
- Yes. Haverfordwest 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 Haverfordwest installer or one from elsewhere in Pembrokeshire?
- 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 Haverfordwest installer and one from elsewhere in Pembrokeshire, 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 Haverfordwest?
- 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.)
