The local picture
Home energy in Lewes
Most homes in Lewes are on mains gas, but a significant minority rely on electric, oil or LPG heating. Both groups can qualify for support: boiler replacements for gas homes, and heat pump funding for homes off the grid.
That’s about 8,105 of the 46,920 homes in Lewes — higher than the average for the South East.
An estimated 3,932 households in Lewes (8.4%) are in fuel poverty — living on a lower income in a home that’s expensive to heat. That’s in line with the South East average of 8.2%.
