How well do heat pumps perform in Plymouth?

Very well. Plymouth's average winter temperature of 6.2°C is one of the warmest in England, and milder air helps an air source heat pump run more efficiently.

How much does a heat pump cost in Plymouth?

Air source heat pumps typically cost £8,000–£15,000 before the £7,500 Boiler Upgrade Scheme (BUS) grant, which applies in England and Wales only. After the grant, many homeowners pay £500–£7,500. Prices vary by property, so get more than one written quote from MCS-certified installers.

Is it worth switching from gas in Plymouth?

The mild climate means lower heating demand, so gas bills may already be moderate. At the Ofgem price cap for 1 October–31 December 2026, a heat pump (COP 3.2) costs about £60–£100 a year less to run than a 90%-efficient gas boiler for a home using 9,000–16,000 kWh of heat a year, or around £170–£210 a year less if you also cap off the gas supply and stop paying the gas standing charge (about £108 a year). Expect the lower end of that range in Plymouth. Against the cost of a new gas boiler (about £3,000), payback on a heat pump at the median net cost of about £5,400 is roughly 11–14 years.

Can I combine solar panels with a heat pump in Plymouth?

Yes. Solar panels can supply some of the electricity your heat pump uses, mostly for hot water and in spring and autumn. In midwinter, when heating demand is highest, solar output is low, so most of your heating will still run on grid electricity.
