Heat pump questions in County Durham

How many heat pump installers are there in County Durham?
15 MCS-certified firms have a business address in County Durham, 12 of them registered for the Boiler Upgrade Scheme. 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 County Durham?
Yes. County Durham 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 County Durham fit?
All 15 installers in County Durham fit air source heat pumps, which suit the great majority of homes. None currently list ground source or exhaust air systems, so if you need one, look at neighbouring counties.
How do I choose between heat pump installers in County Durham?
10 of the 15 have Google reviews shown on their listing; DMH Electrical and Renewable Ltd has the most with 57. 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 County Durham?
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 County Durham do my install?
Yes — most firms travel 25 to 50 miles, so installers in Northumberland, Tyne and Wear, North Yorkshire and Cumbria will often quote in County Durham too. Distance mainly affects survey availability and aftercare response, so ask where their engineers are based.
