The Ofgem price cap limits the unit rate and standing charge energy suppliers can charge for default tariffs. It is reviewed quarterly. The cap is on the rates, not your total bill · if you use more energy you pay more. The Q2 2026 cap for a typical household is approximately £1,738/year.
Ofgem defines typical domestic consumption as 2,700 kWh electricity and 11,500 kWh gas per year for a medium home. Smaller homes and flats use significantly less. Electric-only homes use more electricity as heating replaces gas.
Key actions include switching to a cheaper fixed tariff, improving insulation (loft, cavity wall, draught proofing), using a smart thermostat, replacing old boiler, fitting LED bulbs, and using appliances during off-peak hours if on a time-of-use tariff. Heat pumps can reduce heating costs significantly.
