UK experts urge 18–21°C thermostat settings to cut heating bills, saving up to £145 yearly.

Experts across the UK recommend setting thermostats to 18°C to 21°C to balance comfort and energy efficiency, with lowering the temperature by just one degree saving up to £145 annually. They warn against raising the thermostat higher to heat homes faster, as boilers operate at a constant rate, and oversetting wastes energy. Consistent use of timers, draught-proofing, using heavy curtains, and wearing extra layers are effective no-cost ways to reduce heating bills. These measures help households save money amid rising energy costs, with annual heating expenses now about £600 higher than in 2022.
