Slow Cooker vs Air Fryer: Which Should UK Kitchens Choose? (2026)

Which is cheaper to run in the UK — a slow cooker or an air fryer?

A slow cooker costs about 20–30p for an 8-hour cook. An air fryer costs about 10–15p for a 20-minute cook. Both are far cheaper than a full-size oven.

Can an air fryer replace a slow cooker?

No. They do different things. Air fryers crisp and roast quickly. Slow cookers tenderise and develop flavour over hours. They complement each other.

Which is better for a family in the UK?

Both are worth having. A slow cooker is brilliant for batch-cooking family stews. An air fryer handles quick after-school meals and snacks.
