Electric blankets are a cost-effective way to keep warm
There are several types of electric blankets, including underblankets, overblankets, and mattress protectors. Underblankets are placed directly on the mattress, providing warmth underneath the sleeper. Overblankets can be placed over the sleeper or inside the duvet cover, functioning as an additional top layer. Mattress protectors combine an electric blanket with a mattress protector, offering comprehensive heating for the entire bed.
The cost of running an electric blanket depends on several factors, including the blanket's wattage, the price of electricity in your area, the temperature setting, and how long you use it for. By using the timer and auto shut-off functions, you can control the cost of running your electric blanket. Additionally, a lower heat setting will use less electricity, and a blanket with a built-in thermostat will only switch on when needed to maintain the desired temperature.
Compared to other heating options, electric blankets are a more cost-effective solution for keeping warm. They are significantly cheaper than running central heating because they only heat a small area around you, rather than an entire room or home. Electric heaters, for instance, are less efficient and more expensive, with a typical 2kW heater costing 54p per hour to run. Similarly, infrared heaters, though cheaper than central heating, are still more expensive than electric blankets, costing around 30p per hour.
In conclusion, electric blankets are a cost-effective way to keep warm during the colder months. They are energy-efficient, inexpensive to run, and provide a cosy and comfortable sleeping environment without consuming excessive amounts of electricity. With their quick heat-up times and adjustable settings, electric blankets allow you to stay warm and save money on your energy bills.

Wattage, usage patterns, and energy-saving features affect running costs
Wattage, usage patterns, and energy-saving features all influence the operating costs of electric blankets.
Wattage is a crucial factor in determining the cost of running an electric blanket. Blankets with higher wattage ratings will consume more energy and be more expensive to run than those with lower wattage ratings. For example, a 150-watt blanket will cost under 4p per hour to run, while a 70-watt blanket will cost less than 2p per hour.
The usage patterns, such as the temperature setting and duration of use, also impact the running costs. Lower temperature settings and shorter usage durations will result in lower operating costs. For instance, a 250-watt blanket used at half power for five hours a night for 120 days will cost approximately 17p per night. Additionally, using the blanket for fewer months during the colder seasons will further reduce expenses.
Energy-saving features, such as timers, automatic temperature adjustments, and Intelliheat+ technology, can help optimise energy efficiency and minimise running costs. Timers allow users to preset a shutdown time, preventing the blanket from running continuously throughout the night. Automatic temperature adjustments enable the blanket to turn on only when needed to maintain the desired temperature. Intelliheat+ technology automatically adjusts the heat based on body and room temperature, maximising efficiency.
The price of electricity in your area also influences the overall cost of running an electric blanket. As of January 2025, the average electricity price in the UK was 24.86p per kilowatt-hour (kWh), according to Ofgem's price cap data. However, prices can vary by region and over time, so checking the current rates for your specific location is essential.
Despite the variations in wattage, usage patterns, and energy-saving features, electric blankets are generally considered a cost-effective option for staying warm. They are designed to warm up quickly and efficiently, consuming minimal electricity. When compared to alternatives like central heating, they offer a more targeted and economical solution for individual warmth.

Energy ratings, temperature settings, and duration of use impact costs
Electric blankets are generally designed to be low wattage, making them an energy-efficient option for staying warm. The cost of running an electric blanket depends on its energy rating, temperature setting, and duration of use.
The energy rating of an electric blanket is the maximum amount of electricity it uses when running on its highest temperature setting. Blankets with a higher wattage will use more energy and cost more to run than those with a lower wattage. Most blankets have an energy rating of 100-300 watts, with some double blankets using as little as 70W of electricity, costing under 2p per hour to run.
The temperature setting also impacts the cost of running an electric blanket. Lower settings use less electricity, so reducing the heat setting can help lower the cost. Additionally, blankets with automatic temperature adjustments that respond to body and room temperature changes can help maximise efficiency.
The duration of use also affects the overall cost. Using the blanket for fewer hours and only during the colder months can help reduce costs. For example, a 250-watt blanket used at half power for five hours a night for 120 days would cost approximately 17p per night.
To manage the running costs of an electric blanket, it is important to consider factors such as wattage, usage patterns, and energy-saving features. By adjusting the heat and timer settings and utilising the auto shut-off function, users can control the cost while still enjoying the warmth and comfort of an electric blanket.
