Are Devon homes good candidates for heat pumps?

Many are excellent candidates. Devon has a high proportion of homes on oil or LPG heating, where the savings from switching to a heat pump are largest. The mild South West climate means high efficiency.

How much could I save switching from oil in Devon?

Devon homeowners on oil heating often spend £2,000–£3,000 per year. A heat pump could reduce this to £600–£900. After the £7,500 BUS grant, payback can be as quick as 5–7 years.

Do rural Devon properties suit ground source heat pumps?

Rural properties with large gardens are ideal for ground source systems, which are more efficient than air source. While installation costs are higher (£15,000–£35,000 before grant), the long-term running costs are lower.

What about listed Devon properties?

Devon has many listed buildings. Air source heat pumps may need listed building consent for outdoor unit placement. Ground source heat pumps are invisible once installed, making them a good option where visual impact matters.
