With rising electricity prices in the UK, many people are now asking whether air fryers are actually cheap to run — especially in small kitchens where appliances are used frequently.
The good news is that air fryers are generally far cheaper to run than ovens, but running costs can vary depending on wattage, cooking time, and how often you use them. This guide explains exactly what it costs to run an air fryer in the UK, using realistic examples rather than marketing claims.
How Much Does an Air Fryer Cost to Run in the UK?
For most UK households, running an air fryer costs between 7p and 15p per use, depending on wattage and cooking time.
That makes air fryers one of the most energy-efficient cooking appliances for everyday meals.
UK Electricity Price Assumption (Important)
All examples below are based on an average UK electricity rate of ~28 p/kWh.
Actual costs may vary slightly depending on your tariff.)
Typical Air Fryer Running Costs (UK Examples)
🔹 Low watt air fryer (900–1200W)
- Typical cook time: 15–20 minutes
- Cost per use: ~7p–10p
🔹 Mid-range air fryer (1300–1600W)
- Typical cook time: 15–25 minutes
- Cost per use: ~10p–15p
🔹 Large / dual air fryer (1800–2200W)
- Typical cook time: 20–30 minutes
- Cost per use: ~15p–25p
For small kitchens and single-person cooking, lower wattage models are noticeably cheaper to run over time.
Air Fryer vs Oven: Running Cost Comparison
This is where air fryers really shine.
| Electric oven | ~30p–50p |
| Air fryer | ~7p–15p |
Air fryers heat faster, cook smaller portions, and don’t waste energy heating unused space — which makes them far more efficient for everyday meals.
Does Wattage Really Matter?
Yes — but not as much as people think.
Higher-watt air fryers:
- Use more power
- But it often cooks faster.
Lower-watt air fryers:
- Use less power
- May take slightly longer
In practice, overall running cost differences are usually small, but low watt models still make sense in:
- Small kitchens
- Flats with older electrics
- Homes cooking smaller portions

How Often You Use It Matters More Than Wattage
A high-watt air fryer used occasionally may cost less overall than a low-watt model used multiple times a day.
Typical monthly cost examples:
- Light use (3–4 times/week): £1–£2/month
- Daily use: £3–£5/month
- Heavy use (multiple times/day): £6–£8/month
For most households, air fryer running costs are negligible compared to ovens.
Tips to Reduce Air Fryer Running Costs
Preheat only when needed.
Many meals don’t require preheating — skipping it saves energy.
Avoid overcrowding
Overfilling increases cooking time and energy use.
Choose the right size.
Using a large air fryer for small portions wastes power.
Our Air Fryer Size Guide for Small Kitchens (UK) explains how to choose the right size for your kitchen.
Clean regularly
Grease buildup reduces efficiency and increases cooking time.
Are Air Fryers Cheap to Run in Small UK Kitchens?
Yes — and they’re often ideal.
In small kitchens:
- Portions are smaller
- Cooking times are shorter.
- Heat loss matters more.
That makes compact air fryers especially cost-effective for flats, studios, and smaller households.
Running Costs vs Other Small Appliances
Compared to:
- Mini ovens
- Microwaves (for full meals)
- Hobs for small portions
Air fryers often strike the best balance of speed, cost, and convenience.
While running costs are important, choosing an air fryer that actually fits your space matters just as much. Using an oversized model for small portions can waste both energy and counter space, especially in compact homes. Our guide to the Best Air Fryers for Small Kitchens (UK) compares models that balance size, efficiency, and everyday usability.
Final thoughts
For most UK households, air fryers cost pennies per use and are significantly cheaper to run than ovens. While wattage plays a role, how you cook and how often you use the air fryer matter more.
If keeping energy use low is a priority, choosing a right-sized, efficient model will save money over time — especially in small kitchens.
