Best electric blankets: warm and comfy picks for single, double and king-size beds

Keep your bed cosy, toasty and warm this winter with our pick of the best electric blankets, including tried-and-tested recommendations from Mumsnetters.

Electric blanket on a bed

As temperatures drop and the nights draw in, a cosy bed is shooting up Mumsnetters’ lists of priorities. What could be more delicious than snuggling into a pre-warmed bed at the end of a busy, chilly winter’s day?

An electric blanket will quietly heat up your bed to the perfect level of toastiness, and keep it that way while you sleep. If your partner happens to prefer cooler temps, many modern electric blankets feature dual controls meaning one side of the bed can be arctic while the other’s tropical. 

There’s also the matter of central heating bills. With energy companies in crisis and prices set to soar this winter, an electric blanket is a wise investment that will allow you to keep warm all night for pennies - there are even blankets with settings just for cold feet, how’s that for energy efficiency? 

With a huge array of products on the market, we’ve done the legwork for you and rounded up Mumsnetters’ favourite electric blankets in a range of categories. 

Here are the best electric blankets to buy in the UK in 2021.

1. Best overall electric blanket: Dreamland Scandi Underblanket

Dreamland Scandi electric blanket

Price: £70 | Buy now from Argos

"Yes you need a mattress topper! I swapped to the new Dreamland Scandi topper. It has elasticated corner straps rather than fitting like a bed sheet. Heated mattress toppers are life changing - I've been using them for 2 years" - MustBeThin

For an electric underblanket that heats up fast and keeps you at just the right level of cosiness all night, the Dreamland Scandi is our pick for the best electric blanket. Its 'intelliheat' technology actually monitors the temperature of your body and bedroom and adjusts itself accordingly, so there’s no fiddling with the settings once you’ve warmed up. The double-size blanket comes with dual or single controls, and the king- and super-king blankets come with dual controls only. The corner straps mean the blanket will stay put without the faff of tucking in an elasticated skirt, plus you can turn it over and use it as a standard mattress topper during the warmer months. 

Key specs

  • Electric blanket type: Underblanket
  • Auto-off timer: Yes
  • Dual controls: Available
  • Material: Polyester
  • Size range: Single to Super king-size

2. Best budget electric blanket: Silentnight Comfort Control Electric Blanket

Silentnight Comfort Control electric blanket

Price: From £19 | Buy now from Amazon

"Love mine it is a Silentnight one" - AutumnColours9

For a basic, no frills electric blanket, the Silentnight Comfort Control is a winner. It’s smaller than a mattress so it only heats up the bit you sleep on, and it's held in place by elasticated straps that go right under the mattress. With running costs from 1p per night, it’s the bargain that keeps on giving. 

Key specs

  • Electric blanket type: Underblanket
  • Auto-off timer: Yes
  • Dual controls: No
  • Material: Polyester
  • Size range: Single to king-size

3. Best electric blanket with a timer: Snuggledown Intelligent Warmth

With a timer, dual controls and nine different heat settings, the Snuggledown Intelligent Warmth electric blanket lets you customise its heat to fit your needs. It’s thicker than other brands, with two layers of padding, one of which is removable. It costs from 1p for eight hours of use, and the double and king sizes come with dual controls. 

Key specs

  • Electric blanket type: Underblanket
  • Auto-off timer: Yes
  • Dual controls: Yes

4. Best fast heat electric blanket: Slumberdown Perfectly Warm Dual Control Electric Underblanket

Slumberdown Dual Control electric blanket

Price: £68 | Buy now from Argos

"I found it after lots of research and it's great. Very easy to use and heats up quick. It's the same price as your single and my husband just doesn't turn his side on" - phenomenalcat

"I love it. On the highest setting it heats while I brush my teeth and it's safe to leave on while you are in bed on the low settings. It's dual control so across the whole bed but dh doesn't plug his side in. He does get a bit annoyed by the bit of plastic socket on the edge of his side of the bed though. I use it pretty much every night November-March and sometimes more!" - fruitpastille

This Perfectly Warm electric underblanket by Slumberdown heats up fast, making your bed gloriously warm. It has elastic straps that fit under your mattress, which makes it trickier than other styles to put on, especially if you have a large or heavy mattress.

Brilliant for those with chilly feet or toasty partners, Mumsnetters love the ability to choose separate settings for each quarter of the bed.

Key specs

  • Electric blanket type: Underblanket
  • Auto-off timer: Yes
  • Dual controls: Yes
  • Material: Polyester
  • Size range: Single to super king-size

5. Best fleece electric blanket: LIVIVO Heated Electric Overblanket

LIvivo electric blanket

Price: £45 | Buy now from Amazon

"It's amazing. So snuggly and warm and machine washable" - Bubblysqueak

If you’re after something a little different to a traditional electric blanket that goes under your bedsheets, a heated throw or overblanket like this one from LIVIVO could be just right for you. It comes in four colours, is made from soft fleece and is machine washable. It can be used anywhere there’s a plug socket so it’s perfect for keeping you toasty in bed, in your living room or while you work from home. 

Key specs

  • Electric blanket type: Overblanket
  • Auto-off timer: Yes
  • Dual controls: No
  • Material: Polyester

6. Best washable electric blanket: Cosi Home Luxury Heated Throw

Cosi Home electric blanket

"I have 2 ... one for bed and one for the sofa..... Best things ever! Used daily and wash well too" - CrazyDuchess

Looking just like a fleecy blanket, this Cosi Home heated throw will be at home in any room of the house. Available in four colours, it washes well at 40 degrees and has nine heat settings so you can achieve the perfect temperature. It’s got a nine-hour timer, overheat protection and an auto-off function, so even if it does get left on there’s no danger of a scorched sofa. 

Key specs

  • Electric blanket type: Heated throw
  • Auto-off timer: Yes
  • Dual controls: No

7. Best dual control electric blanket: Dreamcatcher Electric Underblanket

Dreamcatcher electric blanket

Price: £50 | Buy now from Amazon

"You need to get a dual control one with a skirt or tuck in bit just like a fitted sheet. This will keep it fitted snuggly to the mattress so it doesn't move around and become lumpy" - ZacharyQuack

"We have the dual control one too. My side will be on maximum and DH won’t have switched it on. It’s the best present I’ve ever been given. Apart from my heated throw. That comes a close second" - LooksLikeImStuckHere

A dual control electric blanket is divided into two halves of the bed, meaning you and whoever you happen to be sharing with can set the heating to your liking. Mumsnetters recognise this as a recipe for marital bliss, and this dual control blanket from Dreamcatcher is a brilliant choice for those with a partner who has a very different microclimate to their own. It’s fully fitted with an elasticated skirt, so it’ll stay in place all night. At 2p an hour, it’s more expensive to run than other blankets, but at 16p for eight hours it’s still much cheaper than having the central heating on. 

Key specs

  • Electric blanket type: Underblanket
  • Auto-off timer: Yes
  • Dual controls: Yes
  • Material: Polyester
  • Size range: Single to king-size

8. Best electric underblanket: Homefront Fitted Electric Blanket

Homefront electric blanket

Price: £85 | Buy now from Amazon

"I love mine (it's one that goes under your sheets.) Our house was very cold and quite often I would get into bed early to watch TV on the tablet rather than sit up in the living room" - Jamaisjedors

With an ultra-soft fleecy finish, this underblanket from Homefront will make bedtime even cosier. With separate settings for your body and feet, this one is also a great choice for those with arthritis or circulation problems.  It fits to your bed with an elasticated skirt for minimal shifting around, plus it has 10 timer settings. Our favourite thing about this blanket is that the controls light up - an ingenious touch, perfect when you need to adjust the temperature in the middle of the night.

Key specs

  • Electric blanket type: Underblanket
  • Auto-off timer: Yes
  • Dual controls: Yes
  • Material: Polyester
  • Size range: Single to super king-size

9. Best luxury electric blanket: Dreamland Alaskan Husky Faux Fur Heated Throw

Dreamland electric blanket

Price: £100 | Buy now from Amazon

"I baulked at the price but it has been very useful, not least when I had flu and the builders were coming and I had to be at least partly functional all day. I sat on the sofa under it all day snoozing and pretending to be up and about" - 9uncturedicycle

Costing less than 1p per night to run, this expensive-looking throw is a luxury that earns its keep. Despite its luxe looks, it can be chucked in the washing machine to keep it at its best.  It’s supersoft, and it works well as a normal throw - the fact it warms up is an added bonus. If this level of soft and cosiness seems like a one-way ticket to falling asleep on the sofa, you’ll be glad of its auto shut-off and a timer that can be set for between one and nine hours. 

Key specs

  • Electric blanket type: Heated throw
  • Auto-off timer: Yes
  • Dual controls: No
  • Material: Faux fur
  • Size range: One size (120x160cm)

How to buy the best electric blanket 

The main types of electric blanket are:

  • Underblanket: This fits under your bedsheets and warms your bed up from below
  • Dual control: An underblanket with two separately controlled halves - one for each person in the bed
  • Heated throw: Looks and works like a throw, can be plugged in and used in any room
  • Overblanket: Similar to a heated throw, an overblanket is designed to be a layer between you and your duvet

The best style for you will depend on what you want to use the blanket for. If you need cosiness overnight only, an underblanket is best. But if you’re looking to keep warm during the day too, a heated throw is a more versatile option. 

Are electric blankets safe to use?

Yes, although earlier versions of electric blankets were a fire hazard, modern electric blankets typically have safety features like overheat protection and auto-off timers. However, most aren’t suitable to be used with memory foam mattresses. Electric blankets should have a UK safety standard mark.

Are electric blankets expensive to run?

No - they’re far cheaper than running central heating at night, and costs start from less than 1p for eight hours. 

Are electric blankets washable?

Yes, most electric blankets on the market in 2021 are machine washable. Simply unplug the blanket from the power cable and the fine wires within are safe to go in the washing machine. Make sure the blanket is completely dry before using it again. 

What is the best electric blanket to buy? 

The Dreamland Scandi Underblanket is our pick for the best electric blanket to buy. We love its ease of use, quick warm-up time and temperature-regulating technology. 

How we chose our recommendations 

We spent several hours sifting through Mumsnet's forums for recommendations from our users on the electric blankets they rate most highly. We were also on the lookout for poor reviews of products to avoid.

We consulted recommendations from experts, consumer websites and print media and made sure we included brands that regularly appeared in top 10 lists.

We then looked at reviews for each of our longlisted heated throw blankets to check that previous customers were satisfied with their purchases.

By doing this, we whittled our longlist down and chose a selection of products that we think offer something for everybody.
