The local picture
Home energy in Southampton
A large share of homes in Southampton 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 29,214 of the 111,050 homes in Southampton — higher than the average for the South East.
An estimated 10,779 households in Southampton (9.8%) are in fuel poverty — living on a lower income in a home that’s expensive to heat. That’s higher than the South East average of 8.2%, which is why grant funding here is so important.
