Can I get the Boiler Upgrade Scheme grant in West Sussex?
Yes. West Sussex 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 West Sussex fit?

27 of the 41 have Google reviews shown on their listing; Denver Services Ltd has the most with 325. 2 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 West Sussex?
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 West Sussex do my install?
Some installers based in East Sussex, Surrey and Hampshire may serve West Sussex. Business address does not establish service coverage, so ask each firm whether it surveys and supports homes in your postcode.
