From running costs to cooking time, we break down the key differences between air fryers and ovens so you can decide what works best for your lifestyle.
Air fryers have become a staple in many modern kitchens, offering a quicker, healthier way to cook everyday meals without sacrificing taste or texture.
An air fryer uses rapid air circulation technology to cook food from all angles using convection heat. This creates a crispy, golden texture similar to deep frying, but with significantly less oil. The compact design also means faster cooking times and greater energy efficiency compared to larger appliances.
Air fryers excel at cooking smaller items like chips, chicken nuggets, vegetables, and even reheating leftovers. They're perfect for quick meals, healthier snacks, or when you don't want to heat up the whole kitchen. Many models also offer settings for baking and grilling, adding even more versatility.
Conventional ovens are a kitchen essential, providing the space and flexibility to prepare everything from weeknight dinners to holiday roasts.
Most conventional ovens use either electric coils or gas heat to cook food from the bottom and top, with fan-assisted models offering improved heat distribution. They often feature multiple shelves, timers, and grill options. While slower to heat up than air fryers, they’re ideal for larger or more complex meals.
From casseroles and sheet-pan dinners to baked goods and Sunday roasts, conventional ovens can handle large portions and diverse cooking needs. They're especially useful when cooking for families or preparing multiple dishes at once, making them a cornerstone in most households.
Understanding how much electricity each appliance uses is key to evaluating long-term savings.
Air fryers typically operate between 800–2,000 watts, while conventional ovens range from 2,000–5,000 watts. This means air fryers generally consume less energy per minute of use, especially for smaller meals or snacks.
Due to their lower wattage and faster cooking times, air fryers can use up to 50% less energy per use than traditional ovens. For households using an air fryer regularly, this could translate to noticeable savings on monthly energy bills.
Cooking speed plays a huge role in determining overall energy consumption between the two appliances.
Because air fryers reach cooking temperature almost instantly and cook faster overall, they use less energy during a typical session. Ovens, by contrast, often require 10–15 minutes of preheating, which contributes to additional electricity use.
Air fryers don’t require preheating in most cases. Even when they do, it takes just a minute or two. Ovens, on the other hand, need significantly longer to preheat, especially if baking at high temperatures — making them less energy efficient for quick meals.
The upfront cost of an appliance can impact how soon you'll see a return on your investment through energy savings.
Air fryers start as low as £40 for basic models, while premium versions can cost up to £200. Conventional ovens are more expensive, with entry-level models starting around £200 and climbing well into the thousands for built-in or range units. This makes air fryers a more accessible option for budget-conscious buyers.
Beyond the purchase price, how much it costs to use and maintain your appliance adds up over time.
Running an air fryer for 20 minutes can cost as little as 6–10p, depending on your local energy rates. A similar task in an oven might use double the electricity, especially with added preheat time. Over a year, frequent oven use could add £50–£100 more to your energy bill than an air fryer.
Air fryers typically require less upkeep — just a regular clean of the basket and interior. Ovens need deep cleans, potentially costly replacement parts (like heating elements), and may incur callout fees for repairs. However, ovens tend to last longer overall, especially if properly maintained.
Air fryers are known for their speed and crisp results, but they have some limitations too.
Air fryers cook quickly, use less oil, and are ideal for small portions and quick snacks. They're great for reheating food and perfect for crispy textures like chips, chicken wings, and pastries.
Due to limited capacity, cooking large meals or multi-component dishes can be tricky. The texture isn’t always suitable for baked goods or dishes needing slow, even heat.
Traditional ovens offer versatility and consistency, but they’re slower and less energy-efficient.
Conventional ovens are great for roasting, baking, and cooking large quantities. You can use multiple trays and cook a full meal at once, making them ideal for families and batch cooking.
They require longer preheat times, use more energy, and may dry out smaller portions or delicate items. Cleaning can also be more of a hassle.
Choosing the right appliance depends on household size and daily routines.
For larger families or anyone regularly preparing full meals, a traditional oven remains the more practical option. However, an air fryer can be a great supplementary appliance for quick snacks, children’s meals, or when you don’t want to heat the entire oven. Many households benefit from owning both for flexibility.
Using less electricity generally leads to a smaller carbon footprint — but not all energy sources are equal.
Air fryers typically use less power and cook faster, meaning fewer carbon emissions per meal. If your home uses green or renewable energy, this benefit is even greater. Ovens use more electricity per use, so switching to an air fryer could contribute to a more sustainable household over time.
Environmental impact isn’t just about electricity — it’s also about what happens when appliances wear out.
Air fryers often contain more plastic and electronic components, which may be harder to recycle. Ovens, while larger and more durable, are typically made from metal and last longer with fewer replacements. Choosing high-quality, repairable appliances and recycling responsibly makes a difference, regardless of type.
Air fryers shine in specific situations where speed, convenience, and crispness are key.
If you’re cooking for one or two people, want quick snacks or meals, or are aiming to reduce oil without sacrificing crunch, an air fryer is a smart and energy-efficient choice. It’s perfect for busy professionals, students, or anyone with limited kitchen space who still wants freshly cooked food without the hassle.
Ovens remain essential for large meals and traditional recipes that require more space and steady, even heat.
If you often bake, roast, or cook for a family, a conventional oven offers unmatched flexibility and volume. It's also better suited for foods that require slower, more controlled cooking — like casseroles, roasts, and baked desserts. For many households, it’s still the primary workhorse in the kitchen.
Choosing between an air fryer and a conventional oven depends on your lifestyle, habits, and cooking goals.
Consider how often you cook, the size of your meals, energy usage, and the types of dishes you enjoy making. While an air fryer is ideal for speed and simplicity, ovens offer unmatched versatility. Your choice should reflect your household’s cooking patterns and priorities.
Absolutely — and for many homes, they do.
Using both appliances allows you to enjoy the strengths of each. Use your oven for weekend roasts or batch baking, and your air fryer for weekday dinners and reheating leftovers. This combined approach can save energy, speed up meal prep, and give you more flexibility in the kitchen without sacrificing quality or taste.
