Heat pump questions in Greater London

How many heat pump installers are there in Greater London?

114 installer listings have a business address in Greater London; 85 are recorded as registered for the Boiler Upgrade Scheme. They cluster in London (50), Edgware (4), Enfield (4) and Hounslow (3). Check each firm's current MCS and Ofgem status before relying on a grant.

Can I get the Boiler Upgrade Scheme grant in Greater London?

Yes. Greater London 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.

What types of heat pump do installers in Greater London fit?

All records in Greater London list air source; 4 also list exhaust air. Ask each firm to confirm its current technology scope and whether a system suits your home.

How do I choose between heat pump installers in Greater London?

78 of the 114 have Google reviews shown on their listing; Octopus Energy Services Limited has the most with 7,601. 4 have claimed ownership of their listing. Ask firms if they serve your postcode, check current certification and BUS registration, and compare itemised quotes after a heat-loss survey.

Do I need an EPC to get a heat pump grant in Greater London?

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 Greater London do my install?
