Home energy in Wiltshire
A large share of homes in Wiltshire are off the gas grid, typically heated by oil, LPG or electric heaters. These are some of the most expensive ways to heat a home — and exactly what heat pump and off-gas grants are designed to replace.
That’s about 70,349 of the 231,750 homes in Wiltshire — higher than the average for the South West.
An estimated 21,977 households in Wiltshire (9.6%) are in fuel poverty — living on a lower income in a home that’s expensive to heat. That’s in line with the South West average of 9.9%.
