Heat pump questions in Southampton
- How many heat pump installers are there in Southampton?
- 8 MCS-certified firms are based in Southampton itself, and 70 more across the rest of Hampshire will usually travel to quote. Gair Gas LTD is the most reviewed locally with 623 Google reviews.
- Can I get the Boiler Upgrade Scheme grant in Southampton?
- Yes. Southampton is in England, 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. Lower-income households in England may qualify for the fully funded Warm Homes: Local Grant through their council instead.
- Should I use a Southampton installer or one from elsewhere in Hampshire?
- 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 Southampton installer and one from elsewhere in Hampshire, 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 Southampton?
- 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.)
