How well does solar work in South West?
The South West gets some of the most sunshine in England, which makes it one of the best regions for solar. Many rural homes here are off the gas grid, so solar paired with a heat pump can make a big difference to running costs.
Covers Cornwall, Devon, Somerset, Dorset, Wiltshire, Gloucestershire and Bristol.
What does it cost?
Prices across England are fairly similar. A typical 3 to 4 kW system for a three-bedroom home costs around £7,300 installed, according to MCS data from February 2026, with no VAT to pay until 31 March 2027. See our full cost guide.
Grants and loans in South West
If your household is on a lower income, your council may be able to fund solar panels through the Warm Homes: Local Grant. All homeowners should be able to apply for low and zero-interest loans under the Warm Homes Plan once details are published later in 2026. Check what you could get.
