How Much Electric Does Electric Blanket Use

Electric blankets are becoming increasingly popular in the UK as households look for ways to stay warm without relying solely on central heating. With rising energy prices, many people are asking how much electricity an electric blanket actually uses and whether it is a cost-effective way to stay comfortable during colder months. Understanding the power consumption of electric blankets can help homeowners, tenants and landlords make informed choices about energy use and heating efficiency.

Understanding Electric Blanket Power Ratings

Most electric blankets are designed to be highly efficient, using far less electricity than traditional heating systems. The average electric blanket has a power rating between 50 and 100 watts. This means that even when used for several hours, the overall consumption is relatively low compared to the kilowatts needed to run an electric heater or keep central heating switched on for extended periods. To put this into perspective, a one-hour use of a 100-watt electric blanket consumes just 0.1 kilowatt-hours of electricity.

Cost of Running an Electric Blanket in the UK

To calculate the running cost of an electric blanket, you can multiply its wattage by the number of hours used and then apply the current electricity tariff. With average UK electricity prices around 28 pence per kilowatt-hour, a 100-watt blanket running for 8 hours overnight would use 0.8 kilowatt-hours, costing approximately 22 pence. This is significantly cheaper than heating an entire bedroom with central heating, which can use several kilowatt-hours in the same timeframe. Over the course of a month, even with daily use, the cost of an electric blanket typically remains under £10.

Comparing Electric Blankets with Other Heating Options

One of the main advantages of electric blankets is their ability to deliver direct warmth without heating unused spaces. Central heating warms the entire property, which is often unnecessary if you are only using one room. Portable electric heaters consume much more electricity, often between 1,000 and 3,000 watts, making them more expensive to run. By comparison, electric blankets offer targeted heating at a fraction of the cost. This makes them especially appealing for people looking to reduce energy bills while maintaining comfort.

Different Types of Electric Blankets and Their Consumption

There are several types of electric blankets, including underblankets that fit beneath the sheet, overblankets that go on top of the bed, and heated throws designed for use on sofas or chairs. Underblankets generally use less energy as they provide consistent, direct heat. Heated throws often have a higher wattage but are still efficient compared to household heating appliances. Most modern electric blankets come with adjustable heat settings and timers, which allow users to limit consumption further by pre-warming the bed before switching the blanket off during sleep.

Safety Standards and Efficiency Features

All electric blankets sold in the UK must comply with strict safety standards, including British Standard BS 8433 for electric blankets and throws. Modern models are designed with energy-saving features such as thermostatic controls, automatic shut-off functions, and low-voltage technology. These features not only reduce electricity consumption but also provide reassurance for safe overnight use. Older blankets that lack modern safety features may use more electricity and pose safety risks, so replacing outdated models is strongly recommended.

Energy Saving Tips for Electric Blanket Users

There are several ways to minimise electricity use when relying on an electric blanket. Using the pre-heat function for 30 minutes before bedtime and then switching the blanket off can provide lasting warmth without the need for constant power throughout the night. Lower heat settings consume less energy and are often sufficient for comfort. Ensuring good insulation in the home, such as draught-proofing windows and using thicker duvets, can further reduce the need for prolonged electric blanket use.

Environmental Impact of Using Electric Blankets

From an environmental perspective, electric blankets are far more efficient than whole-house heating systems when used sensibly. Because they focus warmth directly where it is needed, they reduce wasted energy that would otherwise go into heating unused rooms. While any use of electricity contributes to overall household consumption, the small amount drawn by an electric blanket is a relatively sustainable option compared to other heating methods.

Final Thoughts

Electric blankets provide an affordable and energy-efficient way to stay warm in colder months. With most models using less than 100 watts of power, the running costs are minimal, often just a few pence per night. By choosing a modern blanket with safety features and using it wisely, households can cut energy bills and reduce reliance on more expensive heating systems. For UK homeowners, landlords and tenants alike, electric blankets represent a practical solution that balances comfort, safety and affordability.
