UK experts urge lowering boiler flow temperature to 55–60°C to save up to 12% on gas and £112 yearly.

As winter heating costs remain high, UK experts recommend lowering a boiler’s flow temperature from 80°C to 55–60°C to cut gas use by up to 12% without sacrificing comfort. This simple adjustment, distinct from lowering the thermostat, improves efficiency and can save households up to £112 annually, especially when combined with other measures like draught-proofing. The change requires no equipment replacement and is part of broader advice to reduce energy bills.
