A heated throw warms the person instead of the room. For anyone who sits still for long stretches, who has arthritis that stiffens in the cold, or who is trying not to put the central heating on all afternoon, that is a genuinely useful trade. A throw drawing 100 watts over an afternoon costs pennies. Heating a whole house to keep one person in one chair comfortable does not.
The catch is that this is the one category in this section of the site with a real safety record behind it. Electric blankets are tested every year by trading standards teams, and a high proportion of the ones people bring in fail. That is worth knowing before you buy, and it changes what you should do with the blanket already on the bed.
How to choose a heated throw or electric blanket
Decide whether you are heating a chair or a bed. A throw goes over you in an armchair and is the right answer for daytime sitting. An underblanket goes beneath the sheet and warms the bed before you get into it. They are not interchangeable, and buying the wrong one is the most common mistake here.
Check it is machine washable, and at what temperature. Anything used daily by someone with limited mobility will eventually need washing. Many throws are washable at 30 degrees with the controller unplugged, some are not washable at all, and the listing does not always make it obvious.
Look for a timer and automatic shut off. Falling asleep under a throw is normal, not a mishap to design around. A unit that turns itself off after an hour or two removes the main risk of leaving one running all night.
Match the controller to the hands that will use it. Small flat buttons and tiny printed numbers defeat arthritic fingers in the dark. A chunky controller with clear settings is worth more than two extra heat levels.
Dual control if two people share the bed. One side warm and one side off is the whole point, and a single control double blanket causes more arguments than it solves.

Best overall: Silentnight Comfort Control Heated Throw
Silentnight is a long established UK bedding brand rather than an unbranded import, which matters more in this category than in most because you are buying a mains powered textile. The throw size suits an armchair and a sofa, and the control is a simple stepped dial rather than a menu.
The catch: the most expensive throw here by some margin. If the person will use it for an hour a day rather than all afternoon, a cheaper one does the same job. Around £45.

Best budget throw: Purus Heated Throw
Nine heat settings and a twelve hour timer at roughly half the price of the branded option. A sensible first purchase if you are not yet sure the person will actually use it, which is a real risk with anything that has to be plugged in and switched on.
The catch: at this price expect a shorter life and a thinner feel. Check the wash instructions on the listing before you commit, because budget throws vary. Around £23.

Best if it will need washing often: GOTCOZY machine washable heated throw
Sold specifically on being machine washable, which is the feature that matters most where there are spills, pets, or any degree of incontinence. A throw that cannot be washed is a throw that gets thrown away.
The catch: always detach the controller and follow the stated temperature. Washing a heated throw the wrong way is one of the ways the internal wiring gets damaged without anything looking wrong from the outside. Around £34.

Best for a shared double bed: Silentnight Dual Control electric blanket
Separate controls for each side, which is the only sensible arrangement when one person feels the cold and the other does not. An underblanket rather than a throw, so it warms the bed rather than sitting on top of you.
The catch: underblankets need to be fitted flat and secured, and a rucked blanket is both less comfortable and less safe. Not the right choice if the bed is remade daily by someone in a hurry. Around £38.

Best budget single underblanket: Status single electric under blanket
Three heat settings, single bed size, and the cheapest realistic way to take the chill off a bed before someone with stiff joints gets into it. Warming the bed for half an hour before bedtime is often all that is wanted.
The catch: basic controller and no timer at this price, so it relies on somebody remembering to switch it off. Around £16.

Electric blanket safety: what the annual testing actually finds
Trading standards teams run free electric blanket testing events every autumn, and the results are consistently poor. Oxfordshire County Council tested 920 blankets in its 2025 programme and 338 of them failed, which is 36.7 per cent, a higher failure rate than the previous year. These are blankets people were still using.
Separately, the Office for Product Safety and Standards published a product safety report covering five styles of electric over-blanket sold between September 2023 and October 2024, finding a serious risk of fire or electric shock arising from deterioration of the cable. Recalls of this kind are listed on the government product recall pages, which are worth checking against anything already in the house.
The practical rules that follow from this:
Replace anything more than ten years old. Age is the single strongest predictor of failure. If you cannot remember buying it, it is old enough to replace.
Never buy one second hand. You cannot see internal wear, and the person selling it usually cannot either.
Look before every use. Scorch marks, exposed elements, fraying fabric, a damaged flex or a cracked controller all mean it goes in the bin, not back on the bed.
Take it to a free testing event. Many county councils and fire and rescue services run them from October onwards. They cost nothing and they take minutes.
Who should not use one
This matters more for a mobility audience than for the general population, and it is usually buried in the instruction leaflet.
Anyone with reduced sensation in the skin, which includes many people with diabetic neuropathy or spinal injury, can be burned by a surface that feels merely warm to someone else. Anyone who cannot move away from the heat unaided, or who cannot operate the controller, should not be left with one switched on. Electric blankets and incontinence do not mix, because moisture and mains wiring are a dangerous combination, and a washable throw is not the same thing as a waterproof one.
Do not use an electric underblanket on top of a pressure relieving air mattress or an adjustable profiling bed unless the mattress manufacturer says in writing that you can. The heat can affect the mattress, and the folding action of a profiling bed puts repeated stress on the wiring.
If any of that applies, a hot water bottle with a cover, a microwaveable wheat bag or simply warmer bedding is the safer answer.
What it actually costs to run
Work it out rather than guessing. Take the wattage on the label, divide by 1,000 to get kilowatts, multiply by the hours you will use it, then multiply by your electricity unit rate in pence.
A 120 watt throw used for four hours is 0.48 kilowatt hours. At an example rate of 25p per unit, that is about 12p. A 60 watt underblanket warming a bed for half an hour is about 0.03 kilowatt hours, well under a penny. Check your own unit rate on a recent bill, because tariffs vary and the figure above is only an illustration.
The comparison that matters is not throw against nothing, it is throw against heating the room. That is where the saving is, and it is the reason these sell out every autumn.
Frequently asked questions
Can you sleep with a heated throw on?
You should not leave one running unattended overnight. Throws are designed for use while you are awake and sitting up, and the safe pattern is to use a timer or to switch it off before you settle. If the aim is a warm bed all night, an underblanket rated for overnight use is the correct product, and even then only if the instructions say so.
Can you wash a heated throw?
Many are machine washable at 30 degrees with the controller detached, but not all, and washing one that is not can damage the wiring invisibly. Check the label rather than the listing photograph, never dry clean, never tumble dry unless it says you can, and let it dry completely before plugging it in.
How old is too old for an electric blanket?
Ten years is the usual guidance, and the annual testing results support it. Local trading standards and fire services run free testing events from autumn onwards, and the pass rate on older blankets is poor enough that replacing an unidentifiable one is cheaper than finding out.
Is a heated throw cheaper than putting the heating on?
For one person in one room, almost always. A throw draws around 100 to 120 watts, which is a few pence an hour, against a gas boiler heating an entire house. It is not a substitute for adequate heating in cold weather, particularly for someone frail, but it does mean you can be comfortable in a chair without warming empty rooms.
Are heated throws safe for someone with dementia?
Only with supervision. The risks are switching it on and forgetting it, not being able to work the controller, and not moving away when it becomes too warm. If the person cannot reliably operate the control, treat the throw as something a carer switches on and off rather than as equipment the person manages themselves.
Can you use a heated throw in a riser recliner chair?
Take care with the mechanism. A throw draped over a chair that folds and tilts can trap the flex in the moving parts, which is exactly how cables get crushed and fail. Keep the cable clear of the mechanism, use the chair in one position while the throw is on, and check the flex regularly.
If cold and stiffness are the underlying problem, our guides to fireside chairs, circulation socks and bed wedges and backrests cover the rest of the picture.
