What changes this appliance’s cost?
Preheating, fan assistance and batch cooking shape oven use. The thermostat cycles, so rated power is not drawn continuously through every minute.
At the illustration above, one use consumes 2.40 kWh. Five uses would cost about £3.24 and twenty uses about £12.96 at 27p/kWh. Your unit rate and measured consumption produce the most useful estimate.
How this example is calculated
Energy equals watts ÷ 1,000 × hours used. The headline uses 27p/kWh and excludes the daily standing charge.
