The Best Electric Blankets in the UK Reviewed

Here’s our detailed breakdown of the top 10 energy-efficient models perfect for British homes.

1. Silentnight Comfort Control Electric Underblanket

The Silentnight Comfort Control Electric Underblanket is a classic for a reason. It perfectly embodies the British desire for value and reliability, offering a straightforward solution to a cold bed without any unnecessary frills. This fitted underblanket is aimed squarely at the cost-conscious user who wants dependable warmth.

Its performance is admirably straightforward. With three heat settings, it provides enough flexibility for most, and the fast heat-up feature is a godsend on those properly nippy evenings. The microfleece material is soft to the touch, and users consistently praise the elasticated straps that keep it firmly in place all night long. For peace of mind, it includes essential overheat protection and an auto shut-off function. Its key selling point is the phenomenally low running cost – at around 1-3p per hour, it’s one of the most economical ways to stay warm. Whilst it may lack the bells and whistles of premium models, this is a solid choice for an affordable winter bed warmer.

• Pros: Remarkably cheap to run, foolproof and straightforward controls, machine washable for easy care.
• Cons: Only three heat settings, functional rather than luxurious feel.
• Best for: Budget-conscious households looking for a reliable, no-frills bed warmer with exceptionally low running costs.

2. PROALLER Heated Blanket

Positioning itself as a versatile and luxurious heated throw, the PROALLER Heated Blanket is an excellent all-rounder for anyone wanting to stay cosy on the sofa. Its reversible design is a real highlight, combining soft flannel on one side with plush sherpa fleece on the other for a genuinely thick and comfortable feel.

This warming blanket offers impressive customisation for its price point. With ten distinct heat settings and a timer that can be set for up to nine hours, you can dial in the perfect level of warmth for any situation. The generous 160x130cm dimensions mean it’s easily large enough for two people to share. Safety is also well-covered with UKCA certification and overheat protection. With a claimed running cost of around 3p per hour, this heated throw provides a brilliant, energy-efficient way to heat yourself instead of the whole room.

• Pros: Very economical to run, luxuriously thick reversible fabric, comprehensive safety features.
• Cons: Neutral beige colour might not suit all interiors, lacks zoned heating of premium models.
• Best for: Couples or individuals seeking a high-value, comfortable, and safe heated throw for the living room or home office.

3. Slumberdown Sleepy Nights Electric Blanket

The Slumberdown Sleepy Nights Electric Blanket is another contender for the “no-nonsense warmth” award. It’s a heated underblanket designed for pure practicality, focusing on efficiently warming your bed so you don’t have to blast the central heating all night.

This warming pad is a model of simplicity. Its three heat settings are more than adequate for taking the chill off your sheets or providing sustained warmth through the night. Where it really inspires confidence is in its safety credentials, boasting BEAB approval (a high standard for UK electricals) and a two-year guarantee. Reviewers, including those at The Guardian, have noted the effectiveness of its generous elasticated straps, which prevent the dreaded midnight bunching. Maintenance is a doddle thanks to the detachable controller and machine-washable fleece cover. The only real drawback for couples is the single controller, which means you’ll have to agree on a temperature.

• Pros: Excellent energy efficiency, BEAB-approved for safety, practical design with secure straps.
• Cons: Single controller for the whole bed, polyester fleece is functional but not plush.
• Best for: Individuals or couples with similar temperature preferences who are looking for a safe, reliable, and cost-effective bed warmer.

The 9-hour auto-off timer and ETL certification add reassuring layers of safety, making it a reliable choice for extended use. Whilst it’s a bit heavier than a standard throw, that extra weight adds to its cosy, comforting feel. This is a brilliant heated throw for anyone prioritising coverage and customisation.

• Pros: Exceptionally soft dual-sided fabric, 10 heat levels for precise control, and a generous size.
• Cons: Large size may be excessive for solo use, slightly heavier than non-heated throws.

It’s an energy-efficient choice, with its 120W power translating to a running cost of around 3.6p per hour. This is an efficient warming device for shared beds.

• Pros: Dual controls for personalised warmth, comprehensive safety features, and secure corner ties prevent slipping.

7. LIVIVO Electric Heated Blanket

With six heat settings and a choice of 1, 3, or 9-hour auto shut-off timers, it offers excellent control and safety. Whilst its 160x120cm size is more suited to one person than two, this is the perfect energy-efficient option for anyone who wants their home comforts to have a touch of glamour.

Head-to-Head Comparison: Key Features

Running Costs & Energy Efficiency

This is, for many, the main event. Almost all models reviewed here are exceptionally cheap to run, typically costing between 1p and 4p per hour. The Silentnight Comfort Control stands out at the lowest end, potentially costing just 1p per hour on its lowest setting. Throws like the Cosi Home and PROALLER are also fantastically efficient at around 3p/h.Bottom line: Any of these options will be vastly cheaper than using central heating, making an energy-efficient warming device a wise investment.

Heat Settings & Control

Control ranges from the beautifully simple to the impressively complex. The Silentnight and Slumberdown models offer a basic, foolproof three-setting system. At the other end, the Homefront underblanket is the clear winner for control enthusiasts, with nine heat settings, ten timer options, dual controls, and zoned heating. For throws, the Mia&Coco and Cosi Home offer a superb ten heat settings. Bottom line: If you share a bed, a dual-control model like the HAUSPROFI is essential to keep the peace.

Fitted Underblankets vs. Heated Throws

This is a crucial choice. Underblankets like the Homefront and Silentnight are designed purely for the bed. They fit securely under your sheet, pre-warming the mattress to create a cosy cocoon. Heated throws, such as the Cosi Home and Dreamland models, are far more versatile. You can use them on the sofa, in your home office chair, or as an extra layer on top of your duvet. Bottom line: Choose an underblanket for dedicated bedtime warmth. Opt for a heated throw if you want a flexible warming solution you can use all around the house.

Material & Comfort

All the models here prioritise a soft touch, but there are degrees of luxury. The polyester fleece on budget models like the Slumberdown Sleepy Nights is perfectly functional. Models like the PROALLER Heated Blanket with its flannel and sherpa combination feel significantly more plush. For sheer indulgence, the faux fur of the Dreamland Hygge Days is unmatched. Bottom line: For pure tactile pleasure, a dual-sided sherpa or faux fur throw is the way to go.

Models with BEAB approval, like the Slumberdown, offer an extra layer of confidence, as this is a recognised UK safety mark.

Frequently Asked Questions (FAQ)

Q: How much does an electric blanket cost to run in the UK?

A: Far less than you might think. Most modern, energy-efficient models cost between 1p and 4p per hour to run. Compared to central heating, which can cost upwards of £1-£2 per hour to heat a whole house, using a personal warming device to heat yourself directly is a massive money-saver.

Q: Is it safe to leave a warming blanket on all night?

A: Yes, provided it’s a modern blanket with the correct safety features. All the models on our list have overheat protection and an automatic shut-off timer, meaning they will turn themselves off after a set period or if they detect an unsafe temperature. Never use an old or damaged blanket overnight.

Q: What is the difference between an underblanket and a heated throw?

A: An underblanket, like the Silentnight Comfort Control, fits onto your mattress like a fitted sheet and warms the bed from underneath. A heated throw (or over-blanket) like the Cosi Home is a loose blanket you can use on top of your duvet or anywhere else, like the sofa.

Q: Can you wash an electric blanket?

A: Yes, all the models featured here are machine washable. You detach the controller(s) and power cord, then you can pop the blanket itself in the washing machine on a gentle, low-temperature cycle. It’s a crucial feature for maintaining hygiene.

Q: Which is the best energy-efficient electric blanket?

A: Whilst all our picks are highly efficient, the underblankets tend to be slightly more so as your duvet traps the heat. The Silentnight and Homefront models, reportedly costing as little as 1-3p per hour, are exceptionally economical choices.

Q: Are heated throws better than central heating for saving money?

A: Absolutely. The principle is “heat the person, not the space.” A 150W heated throw costs pennies per hour, whereas a typical gas boiler uses thousands of watts. Using a personal warming device can let you turn your central thermostat down by several degrees, resulting in significant savings on your energy bills.

Q: Do I need dual controls on my bed warmer?

A: If you share a bed, it is highly recommended. People have very different ideal sleeping temperatures, and dual controls, found on models like the HAUSPROFI underblanket, allow each person to set their side of the bed independently. It’s a minor feature that prevents a lot of arguments.

Q: What safety marks should I look for on an electric blanket UK model?

A: Look for CE or UKCA marking, which shows it meets UK and European safety standards. An even higher standard to look for is the BEAB (British Electrotechnical Approvals Board) Approved mark, which indicates rigorous third-party safety testing.

---

Final Verdict

In the face of rising energy costs, investing in an electric blanket has shifted from a cosy luxury to a shrewd financial decision for UK homes in 2025. It provides targeted, efficient warmth for pennies, allowing you to stay comfortable whilst turning down the central heating.
