Air Fryer Annual Energy Bill: What It Really Costs

An air fryer will not wreck your energy bill, but it is not free either. A typical 1,500-watt model used for half an hour a day adds about £72 a year at the current price cap rate. Here is the maths, worked out step by step.

Key takeaways

  • A 1,500W air fryer used 30 minutes a day costs about £72.05 a year at 26.32p per kWh.
  • Used three times a week, the same air fryer costs about £30.79 a year.
  • The same meal in a 2,000W oven for 45 minutes costs about 39p, roughly double.
  • Real costs run lower than rated-power maths, because the element cycles on and off.
  • Cap rates change quarterly, so check your own bill.

The short answer: what an air fryer adds to your bill

For most households, an air fryer adds between £30 and £100 a year to the electricity bill. The most common case, a 1,500W model used for half an hour a day, costs about £72 a year, or roughly £6 a month.

All figures here use the Ofgem price cap rate of 26.32p per kWh, the average Direct Debit rate for England, Scotland and Wales from 1 October to 31 December 2026. Fixed tariffs differ, and Northern Ireland is not covered by the Ofgem cap.

The formula: three numbers decide your bill

The formula has three parts: your model's power in kilowatts, the time it runs in hours, and your unit rate in pounds per kWh. Multiply the three together for the cost of one cook, then multiply by the sessions in a year.

Find the wattage on the label: most air fryers are rated between 800W and 2,000W. Divide watts by 1,000 to get kilowatts, so 1,500W is 1.5kW, and turn minutes into hours, so 30 minutes is 0.5 hours. At 26.32p per kWh, one cook costs 1.5 x 0.5 x £0.2632, or about 20p.

Worked example: 30 minutes a day, every day

Take a 1,500W air fryer used for 30 minutes a day, every day. This is an illustrative pattern, not a measured average, for a household cooking one main meal in the fryer each evening. Daily energy use is 1.5kW x 0.5 hours, or 0.75kWh, which is 273.75kWh over 365 days.

At 26.32p per kWh, that is 273.75 x £0.2632, or £72.05 a year: about 20p a day, £1.38 a week, and about £6.00 a month. Wattage moves the result most: 800W costs about £38.43 a year, and 2,000W about £96.07.

Worked example: three times a week

Many households use the fryer only for quick midweek meals, or for foods such as chips and chicken. Take the same 1,500W model for 30 minutes a time, but used three times a week instead of seven: another illustrative pattern, not a measured average.

Three sessions a week is 156 sessions a year. Each uses 0.75kWh, so annual use is 117kWh, costing £30.79 a year at 26.32p per kWh. Each cook still costs about 20p; frequency matters more than wattage, because every extra session adds the same 20p.

Air fryer vs oven: the same meal, side by side

The fairest comparison puts the same meal in both appliances. A meal needing 30 minutes in a 1,500W air fryer and 45 minutes in a 2,000W oven, including heat-up time, uses 0.75kWh in the fryer and 1.5kWh in the oven: about 20p against about 39p.

Short cooks in a small cavity are why an air fryer usually beats a full oven.

Over a year at three meals a week, the fryer costs £30.79 and the oven £61.59, a saving of £30.79 a year. Daily, the oven would cost £144.10 against £72.05. The Energy Saving Trust agrees: a 600g chicken breast costs 14p in an air fryer and 20p in an oven.

The oven wins for bigger meals: it cooks a family roast or a week of batch cooking in one session, while a small fryer needs two or three runs.

Why your real bill is probably a little lower

These figures assume the fryer draws full rated power for the whole cook. In practice the element cycles on and off once the fryer is hot, so average power is lower, and the rated-power maths is a ceiling rather than a prediction.

The daily standing charge, about 54.83p a day under the current cap, is paid whether you cook or not, so it does not change when you switch appliances. Use the unit rate on your latest bill for your own answer.

How to keep the cost down

Match the appliance to the meal: the fryer for one or two portions and quick cooks, the oven for a crowd or several dishes at once. Keep the basket closed, since opening the drawer lets hot air out and the fryer must heat up again.

Cook in batches when the basket has room, and switch the fryer off at the plug when you are done. A simple 50-30-20 budget shows where food and energy sit next to the rest of your spending, and our guide to saving money fast on a low income covers quicker wins across the household.

Is an air fryer worth buying to save money?

An air fryer saves about £30 a year for a household swapping three oven meals a week, and about £72 a year for a daily swap. Against a £50 to £150 price, the saving alone takes one to three years to pay for the fryer.

That is not the whole calculation: fryers cook about a fifth faster than an oven and keep the kitchen cooler in summer. Buy one if you will use it often for small meals, and treat the energy saving as a bonus rather than the reason.

Frequently asked questions

How much does an air fryer cost to run per hour?

A typical 1,500W air fryer costs about 39p per hour at the current price cap rate of 26.32p per kWh. A smaller 800W model costs about 21p per hour, and a large 2,000W model about 53p. Most meals take far less than an hour, so a normal 30-minute cook costs roughly half the hourly figure.

How much does an air fryer add to your electricity bill per year?

It depends on the wattage and how often you use it. At 26.32p per kWh, a 1,500W air fryer used for 30 minutes a day costs about 72.05 pounds a year. Used three times a week, the same model costs about 30.79 pounds a year. Smaller models cost less: an 800W air fryer used daily for 30 minutes costs about 38.43 pounds a year.

Is an air fryer cheaper to run than an oven?

Yes, for the same small meal. The Energy Saving Trust found it costs 14p to cook a 600g chicken breast in an air fryer, against 20p in an electric oven. The gap comes from the smaller space to heat and the shorter cooking time. For a large family meal or batch cooking, a full oven can still be the better value because it cooks everything at once.

Do air fryers use a lot of electricity?

No. A 30-minute cook in a 1,500W air fryer uses 0.75 kWh, which costs about 20p at the current cap rate. Cooking takes about 3% of the average home's energy use, according to the Energy Saving Trust, so an air fryer is a small part of a household bill. How often you use it matters far more than the wattage on the label.

How can I work out what my air fryer costs to run?

Find the wattage on the label or manual, divide it by 1,000 to get kilowatts, then multiply by the hours you use it and by your electricity unit rate in pounds per kWh. For example, 1,500W for half an hour is 1.5 x 0.5 = 0.75 kWh, and at 26.32p per kWh that is about 20p. Use the unit rate printed on your own bill for the most accurate answer.
