The local picture
Home energy in Watford
Most homes in Watford 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 7,461 of the 42,650 homes in Watford — lower than the average for the East of England.
An estimated 4,491 households in Watford (10.8%) are in fuel poverty — living on a lower income in a home that’s expensive to heat. That’s higher than the East of England average of 9.3%, which is why grant funding here is so important.
