Yes, air fryers are significantly more energy efficient than traditional ovens. While exact savings depend on model and usage, most air fryers use about 1,400-1,700 watts compared to an oven's 2,000-5,000 watts. This means you're using less electricity for the same cooking task, especially when preparing smaller portions that don't require heating a large oven space.
The secret to an air fryer's energy efficiency lies in its compact design and rapid air circulation technology. Unlike conventional ovens that need to heat a large cavity, air fryers concentrate heat in a small basket where food cooks faster. This targeted approach means less wasted energy and quicker cooking times - perfect for busy households looking to save both time and money on electricity bills.
When you consider that most air fryers cook food 20-25% faster than conventional ovens, the energy savings become even more apparent. For example, cooking frozen chips might take 15 minutes in an air fryer versus 25-30 minutes in an oven. Over time, these minutes add up to substantial savings, especially if you use your air fryer regularly instead of firing up the oven for small meals.
Absolutely! Based on average UK electricity prices, running an air fryer costs about 7-10p per 30-minute use, compared to 20-30p for an oven. If you use your air fryer instead of the oven just three times a week, you could save around £50-£75 annually. For larger families or frequent cooks, the savings can be even more substantial when preparing multiple dishes using efficient appliances like those featured on airfryerrecipe.co.uk.
When asking "does air fryer use a lot of electricity", it's important to consider both wattage and cooking time. While an air fryer's wattage might seem high at first glance (typically 1,400-1,700W), its shorter cooking duration means less total energy consumed. An oven might draw 2,000-3,000W but needs to run much longer to achieve similar results, especially when preheating is factored in.
The difference becomes even more pronounced when cooking smaller portions. Heating a full-sized oven for a single serving of chicken or a handful of roast potatoes is incredibly inefficient. This is where air fryers truly shine - their compact size means no wasted energy heating empty space. For energy-conscious cooks exploring chicken recipes, the air fryer is often the smarter choice.
Calculating exact running costs depends on your electricity tariff, but as a general rule, air fryers cost about 20-30% of what an oven would for the same cooking task. Based on the current UK price cap (34p/kWh), a 1,500W air fryer running for 30 minutes costs approximately 17p. Compare this to a 2,500W oven running for 45 minutes at about 64p, and the savings become clear.
To get the most energy savings from your air fryer, there are several smart practices to adopt. First, avoid overcrowding the basket - proper air circulation ensures even cooking and prevents the need for extended cooking times. Second, consider batch cooking when possible; preparing multiple portions at once (like these easy recipes) maximises energy use.
Regular cleaning also plays a role in maintaining efficiency. A clean air fryer with unobstructed heating elements and fans operates more effectively than one caked with grease and food debris.

Additionally, using the right accessories (like racks or liners) can help cook multiple items simultaneously without compromising results.
In nearly all cases, yes. Even comparing an air fryer's peak wattage to an oven's doesn't tell the full story - it's the combination of lower wattage and shorter cooking times that creates the savings. For example, roasting vegetables might take 40 minutes in an oven but just 15 in an air fryer. When you factor in that many ovens require 10-15 minutes of preheating while most air fryers don't, the energy efficiency advantage becomes undeniable.
Let's look at some common cooking scenarios to illustrate the energy efficiency of air fryers. Cooking frozen chips typically uses about 0.35kWh in an air fryer versus 1.2kWh in an oven - that's 12p vs 41p at current rates. For chicken wings, you might use 0.4kWh (14p) in an air fryer compared to 1.5kWh (51p) in an oven. These savings quickly add up over weeks and months of regular use.
Another advantage is that air fryers don't heat up your kitchen like ovens do, which can lead to additional savings in summer by reducing the need for air conditioning. This makes them particularly useful for preparing summer recipes without turning your kitchen into a sauna. The contained cooking environment also means less heat loss to the surrounding area compared to an open oven door.
