Heat pump questions in East Sussex

How many heat pump installers are there in East Sussex?
38 MCS-certified firms have a business address in East Sussex, 33 of them registered for the Boiler Upgrade Scheme. They cluster in Brighton (8), Eastbourne (5) and Hove (3). MCS certification is a condition of listing here, and it's what every UK grant scheme requires.
Can I get the Boiler Upgrade Scheme grant in East Sussex?
Yes. East Sussex 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.
What types of heat pump do installers in East Sussex fit?
Every installer in East Sussex fits air source heat pumps, and 5 also install exhaust air systems. Air source suits most existing homes; ask about the alternatives if you have the outside space or an unusual property.
How do I choose between heat pump installers in East Sussex?
28 of the 38 have Google reviews shown on their listing; Paynes Heating and Plumbing Services Ltd has the most with 261. Get two or three quotes, check the BUS badge if the grant matters, and ask each firm for a heat-loss survey before they price the job.
Do I need an EPC to get a heat pump grant in East 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 East Sussex do my install?
Yes — most firms travel 25 to 50 miles, so installers in Kent, Surrey and West Sussex will often quote in East Sussex too. Distance mainly affects survey availability and aftercare response, so ask where their engineers are based.
