Are Electric Blankets Expensive to Run? The Truth About Cost & Savings
Are Electric Blankets Expensive to Run?
Electric blankets are one of the most energy-efficient ways to keep warm during cold months. While many assume they consume a lot of electricity, the reality is that electric blankets use significantly less energy than traditional heating methods like radiators and space heaters.
How Much Does It Cost to Run an Electric Blanket Per Hour?
The cost of running an electric blanket depends on its wattage and electricity rates in your area. Most electric blankets use between 40W to 100W per hour.
Here’s a breakdown of the estimated cost per hour:
- Low setting (50W): £0.01 - £0.02 per hour
- Medium setting (75W): £0.02 - £0.03 per hour
- High setting (100W): £0.03 - £0.04 per hour
These costs are based on an average electricity rate of 34p per kWh (UK rates 2024).
How Much Does It Cost to Run an Electric Blanket for 8 Hours?
If you leave your electric blanket on overnight for 8 hours:
- Low setting (50W): £0.08 - £0.16 per night
- Medium setting (75W): £0.16 - £0.24 per night
- High setting (100W): £0.24 - £0.32 per night
Over a month, using an electric blanket for 8 hours a night would cost around £2.40 to £9.60, depending on the heat setting.
Are Electric Blankets Expensive to Run in the UK?
Compared to other heating options, electric blankets are one of the cheapest ways to stay warm. Here’s how they compare:
| Heating Method | Power Usage (per hour) | Cost Per Hour (approx.) |
|---|---|---|
| Electric Blanket (100W) | 0.1 kWh | £0.03 - £0.04 |
| Space Heater (2000W) | 2 kWh | £0.68 |
| Central Heating (Gas) | 3-5 kWh | £1.00 - £1.70 |
Electric Blanket vs Heater: Which is More Cost-Effective?
If you only need to heat yourself rather than an entire room, an electric blanket is far more cost-effective. Running a 2kW space heater for 8 hours would cost around £5.44 per night, while an electric blanket would cost as little as £0.08 - £0.32.
Are Heated Throws Expensive to Run?
Heated throws work similarly to electric blankets but consume slightly more electricity as they are larger. They usually use between 100W to 150W and cost around £0.05 - £0.06 per hour to run, making them a great alternative to central heating for keeping warm in a single space.
Are Electric Blankets Safe to Use?
Electric blankets are generally safe, but they must be used properly:
✅ Do not leave them on all day – This could increase wear and tear.
✅ Check the safety certification – Buy from reputable brands with CE or UKCA safety marks.
✅ Do not fold the blanket when switched on – This can cause overheating.
✅ Replace old electric blankets – If your blanket is more than 10 years old, it should be replaced.
What Happens If You Leave an Electric Blanket on All Day?
If you accidentally leave an electric blanket on for 24 hours, modern models with automatic shut-off features will turn off after a set period. However, older electric blankets without this function may overheat, which could be a fire hazard.
Are Electric Blankets Bad for Your Health?
There is no conclusive evidence that electric blankets cause cancer or harm kidneys. Some concerns about electromagnetic fields (EMFs) exist, but research suggests EMF exposure from electric blankets is minimal and not harmful.
How to Save Money When Using an Electric Blanket
💡 Use a Timer: Set your blanket to turn off automatically after 1-2 hours.
💡 Layer Up: Use a thicker duvet over the electric blanket to trap heat.
💡 Preheat Your Bed: Switch the blanket on 30 minutes before bed, then turn it off when you sleep.
💡 Choose an Energy-Efficient Model: Look for low-wattage blankets with automatic shut-off features.
Final Verdict: Are Electric Blankets Expensive to Run?
No, electric blankets are not expensive to run! They cost only a few pennies per night, making them one of the cheapest ways to stay warm compared to space heaters or central heating.
By using an electric blanket wisely, you can cut heating costs, stay cosy, and save money on your energy bills.
