Air fryer running costs UK depend on the power your appliance actually draws, how long it cooks and your electricity tariff. At the current average capped electricity rate of 26.32p per kWh in Great Britain, a 1,500W air fryer operating at full power for 30 minutes would cost about 19.7p. A typical shorter session may cost less because the heating element cycles and food often finishes within 15–25 minutes.
That is a worked estimate, not a promise about every machine. An air fryer rated at 1,500W will not necessarily draw that much electricity continuously, while large models and repeated batches can use more overall. Here is what an hour, half an hour and regular monthly use could cost, plus when an air fryer can save money against an oven.
Air Fryer Running Costs at a Glance
The table assumes a constant power draw and Ofgem’s October–December 2026 average electricity unit rate for capped variable tariffs paid by direct debit. Real cooking costs depend on thermostat cycling and other features, so treat these as simple upper-style estimates for sustained rated power, not measured performance figures.
| Power Rating | 15 Minutes | 30 Minutes | 1 Hour |
|---|---|---|---|
| 1,000W | 6.6p | 13.2p | 26.3p |
| 1,500W | 9.9p | 19.7p | 39.5p |
| 1,800W | 11.8p | 23.7p | 47.4p |
| 2,000W | 13.2p | 26.3p | 52.6p |
| 2,400W | 15.8p | 31.6p | 63.2p |
The electricity tariff used here comes from Ofgem’s published UK price-cap unit rates. Prices differ by location, payment method and tariff, and fixed-rate customers may pay more or less. Northern Ireland operates under different energy arrangements, so use your own bill rather than assuming the GB average applies.
How Much Does It Cost to Run an Air Fryer for 1 Hour in the UK?
At 26.32p/kWh, running a 1,500W air fryer continuously at full power for an hour costs approximately 39.5p. A 2,000W machine would cost approximately 52.6p under the same assumption. The arithmetic is power in kilowatts multiplied by time in hours, then by the unit price.
Most everyday recipes take less than an hour, and air fryers often cycle their heating elements. Consequently, the actual cost of a one-hour cooking programme may be lower than the continuous full-power figure. If your fryer has two drawers, check whether the rated wattage covers the whole appliance rather than adding both drawer labels incorrectly.
How Much Does It Cost to Run an Air Fryer for 30 Minutes?
For a 1,500W appliance at full output over 30 minutes, the calculation is 1.5kW × 0.5 hours = 0.75kWh. Multiplying by 26.32p gives 19.74p. At 2,000W, the same half-hour would be 1kWh, costing 26.32p.
Actual consumption can differ because the heating element may turn off once the cooking temperature is reached. Some recipes also need preheating; include that time when comparing appliances. You cannot establish a precise half-hour bill from the wattage printed on the product alone.
Air Fryer Electricity Consumption per Hour
Electricity use is measured in kilowatt-hours, or kWh, not simply watts. A 1,500W model draws 1.5 kilowatts when operating at that electrical input. If it stayed at that level for exactly one hour, it would use 1.5kWh. If it drew that power for only half the time, the total would be lower.
Many models quote a maximum or rated wattage, which is useful for estimating but does not reveal the entire heating cycle. The best way to understand your typical meals is to measure one cooking session with a correctly rated electricity monitor, if suitable for your appliance, rather than extrapolating from the label.
Are Air Fryers Expensive to Run UK?
For modest portions, they are often relatively economical. The Energy Saving Trust’s October 2026 cooking comparison gives an illustrative laboratory-tested cost of 14p to prepare a particular 600g chicken portion in an air fryer in Great Britain, compared with 20p for the same portion in an electric oven.
That does not mean every air-fried dinner costs 14p. A larger quantity, longer cook or repeated batches can change the figure. Air fryers are appealing precisely because they heat a smaller cavity and can finish certain meals more quickly, but their advantage is strongest when food fits comfortably into one load.
For a fuller assessment beyond electricity bills, our guide to whether air fryers are worth buying in the UK examines the convenience and practical trade-offs as well as running costs.
Air Fryer Running Costs UK: How to Calculate Your Own
The simple formula is watts ÷ 1,000 × hours × price per kWh. For example, a 1,800W fryer running at a steady full load for 20 minutes uses 1.8 × (20 ÷ 60) = 0.6kWh. At 26.32p/kWh, that is around 15.8p.
For an exact household estimate, look up your tariff’s unit price, note the cooking programme and measure actual consumption if possible. For gas or electricity charges, do not add the entire daily standing charge to the price of one meal. That charge is generally payable whether or not you switch on the fryer.
How Much Does an Air Fryer Cost to Run per Month?
Monthly costs mainly depend on how frequently you cook. If a meal uses 0.35kWh and you prepare one each day for 30 days, consumption is 10.5kWh, costing approximately £2.76 at 26.32p/kWh. Two such cooking sessions daily would cost around £5.53 for the month.
| Illustrative Use Over 30 Days | Monthly Energy | Estimated Cost |
|---|---|---|
| 0.25kWh, 15 sessions | 3.75kWh | £0.99 |
| 0.35kWh, 30 sessions | 10.5kWh | £2.76 |
| 0.50kWh, 30 sessions | 15kWh | £3.95 |
| 0.75kWh, 45 sessions | 33.75kWh | £8.88 |
These are example usage patterns, not measured results or a forecast of your particular bill. The cost of the food itself, cleaning and the appliance’s purchase price are separate. If you use the fryer instead of another cooker, some of its electricity cost replaces energy you would have spent anyway.
Do Air Fryers Make Your Electric Bill Go Up?
Yes, switching on any electric appliance adds electricity consumption. However, if the air fryer replaces cooking in an electric oven, your total electricity use for that meal may fall. The right question is how much additional electricity you use across all cooking appliances, not whether the fryer registers consumption on its own.
If you cook with both your oven and air fryer simultaneously, the saving may be smaller or disappear. Likewise, buying a fryer and using it for extra snacks will increase consumption compared with not preparing those snacks. What matters is whether it replaces another task and how efficiently it completes it.
Is an Air Fryer Cheaper Than an Electric Oven?
Often, for the same small portion. In Which?’s UK cooking tests, a roast chicken used 0.54kWh in the air fryer compared with 1.157kWh in a built-in electric oven. However, an oven can become competitive when it handles multiple trays simultaneously while a fryer requires several rounds.
A compact fryer is especially practical for smaller households. Our one-person air fryer size guide and two-person sizing guide explain how choosing enough usable basket space can help avoid unnecessary batches.
What About Gas Ovens and Microwaves?
A gas oven is a different comparison because gas typically has a substantially cheaper unit rate than electricity. Even if a gas oven uses more kWh for a meal, its total cost might still be competitive. Our air fryer versus gas oven running-cost guide explains why comparisons with electric ovens should not be copied across to gas.
For reheating soup, sauce or a single portion of moist leftovers, a microwave often uses less electricity than an air fryer. If you need a crisp result, the air fryer may be worth the additional energy. See our air fryer versus microwave energy comparison for more detail.
Does a Bigger Air Fryer Cost More to Run?
A larger fryer may have a higher rated power, but that does not automatically mean a higher cost for the same food. If its wider drawer cooks four portions in one programme while a small basket needs two programmes, the larger appliance could use less energy overall.
Household size matters. Our air fryer sizing guide for four people and family-of-five guide explore the trade-off between capacity, usable basket area and extra batches.
Practical Ways to Keep Air Fryer Running Costs Down
- Choose the appliance that fits your portion without needing unnecessary extra rounds.
- Follow recipe and manufacturer guidance on preheating rather than automatically adding extra minutes.
- Cook compatible foods together when there is enough space for airflow.
- Avoid repeatedly opening the drawer and losing heat.
- Compare energy use for the whole meal, including any hob or oven used for sides.
- Use a microwave for suitable quick reheating instead of running a longer hot-air programme.
- Check your actual tariff before applying national-average pence figures.
Never sacrifice safety to save electricity. Electrical Safety First’s UK air fryer advice explains the importance of avoiding overfilling, using a suitable plug and allowing appropriate ventilation.
Frequently Asked Questions
Is It Cheaper to Run an Air Fryer for 20 Minutes or an Oven for 40 Minutes?
It may be cheaper to use the air fryer, but you need each appliance’s actual kWh consumption to be sure. The oven may draw more power overall, while an air fryer can use less energy because it finishes sooner. Wattage and time estimates are only approximations.
Do Dual-Drawer Air Fryers Use More Electricity?
Running two heating compartments can use more power than operating one drawer, but the result depends on the model. Two compartments may also cook a main and side together, avoiding a second session. Check the total appliance rating and consider the complete meal.
Can a 1,500W Air Fryer Really Cost Under 10p per Use?
Yes, for some shorter cooking sessions. At full power for 15 minutes, the calculated cost is 9.9p using 26.32p/kWh. Thermostat cycling could reduce consumption, while preheating or longer cooking would increase it.
Final Verdict on Air Fryer Running Costs UK
For air fryer running costs UK, a useful rule is that a typical short programme can cost only a few pence to a few tens of pence. For example, a 1,500W model at continuous rated power costs around 19.7p for 30 minutes or 39.5p for one hour at Ofgem’s October–December 2026 average rate.
The best way to estimate air fryer running costs UK for your home is to compare your own electricity tariff with measured energy use and the quantity you cook. Air fryers can save money over heating a large electric oven for a small meal, but repeated batches, bigger portions and extra cooking appliances can change the outcome.
