Electric blankets are cheap to run compared to central heating
Electric blankets are a cost-effective way to keep warm, especially when compared to the expense of running central heating. They are relatively cheap to run, with costs varying depending on the blanket's wattage, usage time, and local electricity rates. On average, a 100-watt electric blanket used for an hour costs around 2-3 pence in electricity.
The cost of running an electric blanket can be further reduced by using its adjustable heat settings efficiently. For example, setting the blanket to a lower temperature or using it for fewer hours will decrease its running costs. Some blankets also feature timers and auto shut-off functions, allowing you to control the duration of operation and prevent unnecessary electricity consumption.
Additionally, the insulation of your home plays a role in how much energy your electric blanket consumes. A well-insulated house will require a lower temperature setting on the blanket to achieve the same level of warmth. This means that you can keep your central heating at a lower temperature or even turn it off, resulting in significant energy bill savings.
According to the Energy Saving Trust, simply turning your thermostat down by one degree could save you up to 10% on your annual energy bill. This, combined with the low running costs of electric blankets, makes them a financially savvy choice for staying warm during the colder months.
It is worth noting that the price of running an electric blanket can vary depending on the energy provider and tariff you are on. However, with prices starting from as little as 2p per hour, electric blankets offer a cost-effective solution to staying cosy without breaking the bank.

Costs depend on blanket wattage, usage time, and electricity rates
The cost of running an electric blanket depends on its wattage, how long it is used for, and the local electricity rates.
Electric blankets with lower wattages are more energy-efficient and cost-effective. For example, a 70W electric blanket would cost under 2p per hour to run, while a 150W blanket would cost around 4p per hour. A 100-watt electric blanket costs around 2-3 pence for an hour of usage, according to the UK's average electricity price of 27p per kWh as of October 2023.
The usage time also impacts the cost. For example, a 150W blanket costs 44.7p to run for 12 hours. Using a blanket for fewer hours and at lower temperatures will reduce costs. Some blankets have adjustable heat settings and timers to help manage energy usage.
The local electricity rates also affect the cost. For instance, with an electricity price of 24.86p per kWh as of January 2025, the cost of running a 100W blanket for an hour would be around 2.5p.
Overall, electric blankets are considered economical, especially when compared to central heating, as they only heat a small area.
