How Much Does It Cost to Run Your Oven for 2 Hours?

Leaving your oven on for two hours isn’t just about preparing a meal—it also adds to your energy bill. On average, a typical electric oven uses around 3 kWh per hour when set to a moderate temperature. That means running it for two hours consumes roughly 6 kWh of electricity.

With the average UK electricity rate hovering around £0.30 per kWh, a two-hour oven session comes in at about £1.80. While that might not seem like much for a single use, it can add up—especially if you're roasting, baking, or using the oven frequently throughout the week.

Consider this breakdown for context:

  • 1 hour = 3 kWh = £0.90
  • 2 hours = 6 kWh = £1.80
  • 3 hours = 9 kWh = £2.70
  • 4 hours = 12 kWh = £3.60

These numbers can vary slightly depending on your oven’s efficiency, whether it's fan-assisted, and the cooking temperature. Older models tend to use more energy than newer, energy-rated ones. Also, keeping the door closed and avoiding unnecessary preheating can help reduce overall consumption.

For households watching their energy use, it's worth thinking about cooking habits. Batch cooking for a few days might make sense financially compared to daily use, as it reduces repeated heating cycles. And if you're baking several dishes, try to make the most of that warm oven instead of turning it on multiple times.

So while running your oven for two hours won’t break the bank, small choices in how and when you use it can lead to noticeable savings over time.
