Best Electric Blanket UK 2026: 8 Blankets and Heated Throws Compared

Heat the Person, Not the House

This is the whole case for these things, so it's worth getting right. Every electric heater is 100% efficient: one unit of electricity in, one unit of heat out. What changes the bill is how much of that heat lands on you rather than on the walls, the windows and the empty half of the room.

A blanket or throw is the extreme end of that. It's lying on you, so almost nothing is wasted, and it draws a tiny amount of power to do it. The ones below that publish a wattage draw between 60W and 150W. A fan heater draws 2,000W.

Those are full-power figures, so treat them as the ceiling. On a lower setting a blanket's thermostat switches the element on and off, so it draws less than the headline wattage most of the time. We haven't measured by how much, and neither do the manufacturers publish it, so we've stuck to the numbers we can stand behind.

For the bed, the maths is even kinder, because you don't run it for long. Pre-warming a 150W underblanket for half an hour costs about 2p. Do that every night from October to February and the whole winter comes to around £3. The 60W Beurer is nearer £1.20.

Where it stops working: a blanket or throw keeps you warm while you're still. It does nothing for a cold bathroom, condensation on the windows or a house that's dropping to 12°C overnight. If your home is genuinely cold, that's a heating and insulation problem, and a throw is a way to spend less while you sort it, not a substitute for sorting it.

If you're working out whether to switch off a heater and sit under a throw instead, this calculator does the comparison for your heater and your hours:

Underblanket, Overblanket or Heated Throw?

These get called "electric blankets" interchangeably, but they're three different products for three different jobs.

If you only buy one, buy the underblanket. Most people's coldest moment is getting into a cold bed, and it's also the one where heating the whole house is the most wasteful: you're paying to warm the landing so that you can get into bed and go to sleep.

Single Control or Dual Control?

A double underblanket with one control heats the whole bed to the same setting. That's fine if you sleep alone or if you both like the same temperature. If one of you runs hot, get dual control: two controllers, one per side, so each of you sets your own. It's typically only a few pounds more, and it's the difference between one of you kicking the duvet off at 2am and not.

For a king or super king bed, dual control is close to essential, because you're warming a lot of mattress and one person almost always wants less of it.

Safety: What Actually Matters

Electric blankets have a reputation left over from decades-old kit. A modern blanket from a known brand with overheat protection is a very different thing, but the fire service still has clear advice, and it's worth following. This is from London Fire Brigade:

• Replace it at least every 10 years, and sooner if the fabric is worn or frayed, there are scorch marks, wires are poking through, the cord is damaged, or the control buzzes or smells when it's on.
• Unplug it before you get into bed, unless it has a thermostat control for safe all-night use. Check what your blanket's instructions say rather than assuming.
• Never use a hot water bottle at the same time.
• Don't use one with an air-flow pressure relief mattress, or if you use emollient creams. The MHRA warns that bedding with dried emollient residue on it can "rapidly ignite", and that applies to paraffin-free creams too, which catches a lot of people out.
• Don't buy second-hand. You can't see the wiring, and you don't know how it's been stored.
• Store it flat, rolled or loosely folded, never tightly folded or crushed, because creasing damages the wires inside.

When you're buying, stick to a brand you've heard of that states overheat protection or an automatic switch-off, and has instructions and a guarantee. Every pick below does. The very cheapest unbranded throws often don't say much about either, and that's reason enough to skip them.

What You Don't Need

• A super king blanket for a double bed. It won't fit properly, and the spare ends up bunched or tucked under the mattress. Creased wiring is exactly what the fire service's storage advice is there to prevent, so buy the size of your bed.
• App control or Wi-Fi. You're pre-warming a bed for half an hour. A timer on the controller does the job, and there's nothing to set up or update.
• Nine heat settings. You'll use two of them. Three or four is plenty on an underblanket; six is handy on a throw you sit under for hours.
• A heated mattress topper as well as a blanket. One or the other. Two heated layers is money for nothing and one more thing to replace in ten years.
• Anything second-hand, however cheap. The fire service is unambiguous on this one.

Where This Fits in a Warmer Winter

A blanket or throw is the cheapest warmth you can buy, but it's a personal fix. The whole-house fixes are slower and bigger, and they're what actually bring the bill down year after year: draught-proofing for a few pounds a door, thermal curtains, and loft insulation if yours is thin. If you do need to heat a room, our electric heater guide shows exactly what each type costs per hour.
