Safety concerns and risks
Electric blankets are a cost-effective way to keep warm during the winter. However, there are several safety concerns and risks associated with their use:
Fire Risk
The main disadvantage of an electric blanket is the risk of fire. They are not suitable for use on all types of beds, including bunk beds or water beds. Electric blankets should never be used with other materials that could be flammable, including bed linens or comforters. It is also important to avoid pinching or twisting the blanket, as this could damage its internal connections.
Electric Shock and Short Circuits
The presence of electrical elements woven into the fabric of electric blankets poses a risk of electric shock if the blanket is damaged or faulty. It is important to regularly inspect the blanket for any signs of wear and tear, exposed wires, or damage to the wiring. Damaged blankets should not be used and should be replaced.
User Safety
Electric blankets can pose a danger to children who may not understand the risks associated with their use. It is recommended that young children do not use electric blankets and that they are never placed in an infant's cot. Additionally, electric blankets should not be used on wet bedding or with mattresses that have heating pads.
Misuse
Misuse is one of the common causes of accidents associated with electric blankets. It is important to read and follow the manufacturer's instructions for use and care of the electric blanket. Blankets should be unplugged when not in use and care should be taken when washing and drying to avoid damaging the wiring.

How to calculate running costs
Electric blankets are a cost-effective way to keep warm during the winter. They are designed to heat up quickly and distribute heat evenly over their surface, allowing you to turn down or turn off your central heating system.
To calculate the running costs of an electric blanket, you need to know its wattage and the cost per unit of electricity in your area. Most electric blankets have a wattage between 60W and 150W, although some can go as high as 200W. You can usually find this information in the product description or instruction manual.
Once you know the wattage, you can calculate the kilowatt-hours (kWh) used by dividing the wattage by 1,000. For example, a 150W blanket uses 0.15 kWh (150/1,000 = 0.15).
Next, multiply the kWh by the cost per kilowatt-hour of electricity. According to Ofgem's January 2025 price cap data, the average price of electricity in the UK is 24.86p per kWh. So, for a 150W blanket, the calculation is 0.15 x 0.2486 = 0.037p. This means it costs just under 4p to run a 150W electric blanket for one hour.
It's important to note that the cost of electricity can vary depending on your energy provider and tariff. You can find the exact unit price on your energy bill.
Additionally, the amount of time you use the electric blanket will impact the overall running costs. It is recommended to only use the blanket for a short period, around 10 to 30 minutes, before switching it off. Many electric blankets have timers that can be preset to switch off automatically.
By following these steps and considering your usage patterns, you can calculate the approximate running costs of an electric blanket.
