Heat Yourself, Not the House: What an Electric Blanket Really Costs to Run vs Central Heating

The trend
The clocks have gone back, the storms have arrived, and Britain is reaching for the electric blanket. Look Into’s UK Demand Index found electric blanket searches rose 54.0% week on week to 15 October 2026, the biggest jump of all 20 products it tracks. Hot water bottles (+27.1%) and smart thermostats (+35.6%) weren’t far behind.
Look Into’s own reading of it is spot on: these are products “bought to heat a person rather than a room”. So, does that actually save money? We ran the numbers.
The energy prices right now
From 1 October to 31 December 2026, Ofgem’s price cap for a typical dual-fuel household paying by Direct Debit is (Ofgem):
| Unit rate | Standing charge | |
|---|---|---|
| Electricity | 26.32p per kWh | 54.83p per day |
| Gas | 7.97p per kWh | 29.68p per day |
Worth knowing: the government has removed VAT from electricity bills from 1 October 2026 to 31 March 2027, which makes electric gadgets a bit cheaper to run this winter. Gas still carries 5% VAT. These are averages across England, Scotland and Wales; your exact rate depends on region, meter and tariff.
How to work out running costs yourself
The formula is simple:
Watts ÷ 1,000 × hours × unit rate = cost
Every appliance lists its wattage on the box or the label. That’s the maximum; blankets on a low setting or with a thermostat cycle on and off and use less.
Worked examples (at 26.32p/kWh)
These use round-number wattages for illustration. Check the rating on the actual product you buy.
| Appliance (example wattage) | Cost per hour at full power |
|---|---|
| 60W single electric blanket | about 1.6p |
| 120W double electric blanket | about 3.2p |
| 150W heated throw | about 3.9p |
| 2,000W (2kW) electric fan heater | about 52.6p |
The maths is brutal for plug-in heaters: a 2kW fan heater costs over 30 times more per hour than a 60W blanket.
And central heating?
Gas is cheaper per unit, at 7.97p per kWh, so whole-house heating is harder to compare. How much gas your boiler burns depends on your home’s size, insulation, the boiler’s efficiency and the weather. As an illustration only: a boiler drawing an average of 10kWh of gas in an hour (not unusual for a family home on a cold evening) would cost around 80p for that hour, plus whatever runs the pump.
Even if your house uses half that, you’re still paying many times more than the pennies a blanket costs. The catch is that the blanket only warms you.
When heating yourself makes sense
Good fit:
- Working from home alone all day in a house built for four.
- An hour on the sofa before bed, when the heating’s already gone off.
- Pre-warming a bed for 20–30 minutes so you can keep the bedroom cooler.
- Older relatives who feel the cold more but live in a big, hard-to-heat home.
Not a replacement for:
- Keeping rooms warm enough to prevent damp and mould. Cold, under-heated rooms breed condensation, so pair this with our beat the damp guide.
- Babies, young children, or anyone who can’t feel heat properly or can’t switch the blanket off themselves. These users shouldn’t use electric blankets.
What to look for
- Overheat protection and auto shut-off (often 1–12 hour timers). Non-negotiable.
- Multiple heat settings and, on doubles, dual controls so each side sets their own.
- Machine-washable with the controller unplugged.
- Underblanket vs overblanket vs heated throw: underblankets go under the sheet and warm the bed; heated throws are for the sofa.
- Check the UK safety basics: a UKCA or CE mark, and buy from a reputable retailer.
Safety: don’t use a blanket that’s creased, scorched or more than about 10 years old. Store it rolled, not folded tightly, and never use it alongside a hot water bottle.

The pairing that works
The cheapest warm evening in Britain this winter probably looks like this: heating set a degree or two lower, a heated throw on the sofa, an electric underblanket on for half an hour before bed, and a hot water bottle as backup. A smart thermostat (the other big riser this month) helps you heat only the rooms and hours you need.
The verdict
At October 2026 prices, an electric blanket costs a few pence an hour to run, a fraction of a plug-in heater and much less than heating the whole house for one person. It won’t replace your boiler, but used smartly it lets you turn the dial down. That’s why searches have rocketed.
