How Much Does a Oven Cost to Run?

Updated March 2026. Default rate effective 1 April 2026 (Ofgem Q2 2026). Figures are typical estimates rather than model-specific guarantees.

A typical electric oven costs approximately 36p per hour of cooking and around £80 per year based on cooking for one hour, five days per week. The oven is one of the most energy-intensive kitchen appliances, but its thermostat means it cycles on and off rather than drawing full power continuously.

What Affects the Cost of Running a Oven?

Your oven running costs depend on: Oven type — fan ovens are roughly 20% more efficient than conventional ovens. Temperature — higher temperatures mean more energy. Cooking time — the thermostat cycles on and off, so the duty cycle is approximately 50% after preheat. Preheating — the first 10-15 minutes use the most energy as the element runs at full power. Size — a larger oven cavity takes more energy to heat.

Tips to Reduce Oven Running Costs

Use a fan oven setting where possible — fan ovens cook about 20% faster and at lower temperatures. Avoid opening the oven door during cooking as this drops the temperature by 10-15°C each time. Cook multiple dishes at once to make the most of the preheat energy. Consider an air fryer for smaller meals — it costs roughly a third as much to run.
