Best electric blankets 2025
Matt has been putting products through the mill for more than a decade, from complex heating systems, to his true passion, bikes and bike accessories
We've tested electric blankets ranging in price from around £35 to £150, so we can bring you the best for warmth and value this winter.
We use precise temperature measurements taken with a thermocouple to help you steer clear of the models that barely heat up after 20 minutes, and point you towards those that will be nice and toasty just as it's time to slide between the sheets.
We also measure heat distribution and running costs, and enlist a user panel to assess the comfort of each blanket.
Our testing has found four Best Buy blankets and a Great Value one that offers plush comfort, speedy heating and competitive running costs – at a price that won't give you nightmares.
Electric blankets are not the same as heated throws, which can be a great option if you want a warm blanket for snuggling under in front of the TV, rather than staying warm in bed.
How we test to find you the best
Heating speed and evenness
We test how quickly and evenly electric blankets heat up. The best will be toasty in less than 10 minutes, the worst will take longer than 20 minutes and still have cold spots.
Energy costs and safety
The cheapest electric blankets cost just 2p an hour to run. The most energy-guzzling can cost four times as much.
Comfort and ease of use
We check the blankets for comfort to make sure there are no uncomfortable protruding wires. We also assess how easy they are to attach to a mattress.
We also test...
We check all blankets for electrical safety, although it's important that you always follow the manufacturer's instructions.

Dates tested: Ocotber 2025, October 2024, August 2023, October 2022. Page last checked October 2025. We're not able to show every retailer, and cheaper prices may be available.
Cost per hour is based on using the throw on its highest setting at the current electricity unit price of 26.35p/kWh, because our repeated testing has taught us that this is the setting you're more likely to use.

How we test electric blankets
We've designed a test that captures how quickly and evenly each blanket heats up. We also factor in how comfortable each blanket is, according to a panel of volunteers.
We regularly revisit the electric blankets on sale to see if there are any more popular models that need testing, and when we find them, we do so.
Heating speed and evenness
- Heat-up time We attach temperature sensors to six different locations on each electric blanket and record how quickly each blanket heats up over a five-minute and 20-minute period on their highest setting. The best blankets heat up twice as fast as the poorest. We've also seen some that heat up quickly initially, only for the increase in heat to rapidly taper off.
- Heat distribution Using the six temperature sensors, we record how evenly each blanket heats up. There are big differences here: most heat fairly evenly, but there are a fair few with irregular hot and cold spots.
- Responsiveness Once the electric blanket has reached its maximum temperature, we lower the temperature setting and record how responsive each blanket is.
We've tested a lot of blankets on their lowest settings over the years, and we've found that by and large, these are incredibly ineffective. You'll only see real differences in performance at the highest settings, which is what we use in all our heating speed and evenness tests.
Comfort and ease of use
- Comfort A panel of five volunteers assesses each electric blanket for comfort. There's quite a big difference in how cosy each one feels and how they feel to lie on under a sheet. Underwires are more noticeable in some of them.
- Ease of use We assess how straightforward they are to attach to a thick double mattress.
- Power cord length Manufacturers often don't list the length of the power cords for electric blankets, so we record these figures and tell you how they compare with the average.
Energy use and safety
- Energy use We attach each electric blanket to an energy monitor and record how much energy it uses when running on its highest setting. Prices range from 2p to 7p an hour. While some manufacturers and other online reviews list the cost for the lowest settings, our testing found that this results in such low temperature increases that we don't think it's a realistic setting for keeping warm.
- We used the RS PRO energy meter, £28, from RS Components. If you're interested in measuring your electric blanket or other appliances around your home, you can buy similar meters starting from around £18 from popular retailers such as Amazon and Screwfix.
- Safety After testing, each electric blanket has a full electrical safety test conducted on it.

What is better than an electric blanket?
If you want to keep warm in bed without shelling out for an electric blanket, a cheaper option is a hot water bottle.
The good news is that you don't need to splash out on a pricey one – our testing discovered that paying more doesn't mean you'll stay warmer. Instead, you'll want to invest in a thicker cover, as this is the biggest factor in ensuring your bottle retains heat for longer.
See how the running costs of an electric blanket compare with the cost of boiling your kettle for a hot water bottle in our guide: Hot water bottle or electric blanket, what's best and cheapest for keeping you warm in bed.
Are electric blankets safe?
If you buy your blanket from a reputable UK retailer, as we did for our tests, then it should be safe.
But take extra care if you buy from an online marketplace, as in the past we've found some stocking potentially unsafe electric blankets that can't be sold legally in the UK.
As part of our test, we conduct a full electricity safety test on each blanket. To date, every single one we've reviewed has passed.
Any risk posed by electric blankets tends to come from disreputable online sellers, or old blankets that have become worn and unsafe. If you have an old electric blanket that's showing signs of wear or has visible wires, it could be time for a change.
Is it OK to sleep with an electric blanket?
The London Fire Brigade emphasises that electric blankets can be a safe and cost-effective way to stay warm, provided they're used correctly.
It's recommended that you inspect blankets regularly for signs of wear, such as frayed fabric, exposed wires or overheating connectors, and unplug them before bed unless they have a thermostat for safe overnight use.

What should I look for in an electric blanket?
- How comfy is it and can you feel any wires?
- What are the running costs?
- How long is the cord to ensure you can plug it in without needing a messy (and potentially dangerous) extension lead?
- What's the heat-up time?
- How good is the heat distribution?
- What size is it and will it fit my bed?
We record all these key things to look for in an electric blanket in our reviews, above.
How much does it cost to run an electric blanket?
On their highest settings, we've found that electric blankets cost anywhere between 2p and 7p an hour to run.
Electric blankets in general don't use a lot of electricity, but there are still significant differences between certain models. If you have an electric blanket on every night for three hours, for six months of the year, the most expensive to run would cost you about £30 in energy, while the cheapest would cost about £10.
It's also worth knowing that claimed running costs for electric blankets are usually based on the blanket's lowest power setting. Our repeated testing over the years has found that this setting hardly heats the blankets up at all. That's why our reviews give you the running costs measured from each blanket's highest setting.

How to wash electric blankets
You shouldn't need to wash your electric blanket very regularly, but may wish to give it a clean after heavy use.
Most electric blankets can be washed, but you should check the manufacturer's instructions before doing so.
Remember to remove the cable before washing, and use a low-temperature gentle setting on your washing machine.
