How Much Electric Does Slow Cooker Use

Slow cookers have become a popular kitchen appliance in many UK households because they offer an easy way to prepare meals while saving both time and energy. With rising energy costs, it is natural for people to ask how much electricity a slow cooker actually uses and whether it is more cost effective than other cooking appliances. The good news is that slow cookers are among the most energy efficient kitchen appliances available, making them a practical choice for budget conscious households.

Understanding the Power Consumption of a Slow Cooker

Slow cookers work at relatively low wattages compared to ovens or hobs. Most models fall between 150 and 300 watts depending on their size and settings. This means that even if a slow cooker is left running for eight hours, the total energy consumption is still significantly less than an electric oven used for just one hour. For example, an average 200 watt slow cooker running for eight hours would use 1.6 kilowatt hours of electricity. By contrast, a typical electric oven can consume between 2 and 3 kilowatt hours in a single hour of cooking.

Calculating the Cost of Running a Slow Cooker in the UK

To understand the cost in real terms, you can multiply the power consumption by the average UK electricity tariff. At around 28 pence per kilowatt hour, an eight hour use of a 200 watt slow cooker would cost roughly 45 pence. This is extremely low considering it allows you to prepare a full family meal. Compared to oven cooking, which can cost over £1 for a similar dish, the savings over a month of regular use become noticeable. For people who batch cook or use a slow cooker several times a week, the annual savings compared to oven cooking can easily run into tens of pounds.

Comparing Slow Cookers with Other Appliances

When comparing the energy use of a slow cooker to other kitchen appliances, the benefits become clear. Electric hobs and ovens operate at much higher wattages, often in the range of 1,500 to 3,000 watts. Even air fryers, which are considered efficient, usually use between 800 and 1,500 watts. Microwaves use less power per minute, but because they are not always suitable for cooking larger meals, they are not a direct replacement. A slow cooker is designed to use steady, low levels of electricity over long periods, which allows it to achieve tender, well cooked results while keeping energy bills low.

Why Slow Cookers are Efficient

The efficiency of a slow cooker comes from its design. The insulated outer casing and tight fitting lid mean that very little heat escapes during cooking. Once the appliance reaches its steady cooking temperature, it uses only enough electricity to maintain that level. This contrasts with an oven, which cycles power on and off at high wattages to keep temperatures constant, leading to higher overall consumption. In practical terms, this makes slow cookers an ideal solution for households trying to manage both energy costs and meal preparation.

The Role of Cooking Times and Settings

Most slow cookers have at least two settings, low and high, with some offering additional functions such as keep warm. The low setting typically consumes between 150 and 200 watts, while the high setting uses closer to 250 to 300 watts. Using the low setting for a longer time usually consumes the same or less energy than cooking on high for a shorter time. Because the appliance is designed to run for several hours, it spreads its energy use more efficiently than other appliances, ensuring consistent cooking without surges in electricity demand.

Practical Examples of Energy Savings

Consider cooking a family stew. In a slow cooker, this might require six to eight hours on the low setting, using under 2 kilowatt hours of electricity in total. The cost is less than 60 pence at current tariffs. Cooking the same meal in an electric oven might involve two hours at 2 kilowatts per hour, resulting in 4 kilowatt hours of use and a cost of more than £1.10. Over time, the cumulative effect of these savings adds up, especially for families who prepare meals daily.

Environmental Benefits of Using a Slow Cooker

Reducing electricity use is not only beneficial for household bills but also helps lower overall environmental impact. By choosing to cook with a slow cooker instead of an oven, households can reduce energy consumption and their carbon footprint. Because the appliance uses low wattage over long periods, it contributes to more efficient household energy management, which is an important consideration for sustainability.

Final Thoughts

A slow cooker is one of the most economical appliances in the kitchen. With typical running costs of less than 60 pence for a full eight hour cook, it uses significantly less electricity than ovens, hobs or even some modern cooking alternatives. For households across the UK looking to reduce their energy bills without compromising on home cooked meals, slow cookers represent both a cost effective and environmentally conscious choice.
