- How many heat pump installers are there in Southampton?

- Can I get the Boiler Upgrade Scheme grant in Southampton?
- Yes. Southampton is in England, where eligible properties can receive £7,500 for an air-to-water or ground-source heat pump (£2,500 for air-to-air; £5,000 for biomass). An MCS-certified, Ofgem-registered installer applies and deducts an approved grant from the quote. The £9,000 uplift from 21 July 2026 to 31 March 2027 is only for eligible off-gas-grid homes replacing oil or LPG with air-to-water or ground-source heat pumps. Lower-income households in England may also qualify for the council-run Warm Homes: Local Grant, subject to its separate rules.
- Should I use a Southampton installer or one from elsewhere in Hampshire?
- Compare firms that confirm they cover your postcode. Ask each about survey availability, aftercare response, a room-by-room heat-loss calculation and an itemised quote, and verify current Boiler Upgrade Scheme registration if you plan to use the grant.
- 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.)
