An electric blanket is one of the cheapest ways to stay warm — warming you directly for pennies instead of heating the whole room. Here's how the types compare, plus safety and running costs.
Underblanket or overblanket?
- Underblanket / mattress cover: fitted under your sheet to warm the bed before and during sleep — the most popular type.
- Overblanket / throw: sits on top, so you can use it on the sofa too.
What to look for
- Size: single, double, king — with dual controls so each side sets its own warmth.
- Heat settings & timer to preheat then ease off.
- Safety features: overheat protection and auto shut-off — look for these as standard.
- Washable for easy care.
Running cost & safety
Electric blankets use very little power — typically a few cent per night — making them far cheaper than heating a bedroom. Always check for damage before use, don't fold it while on, and replace very old blankets.
