How to use a heated throw safely: 7 steps
1. Buy new, from a reputable seller
UK fire and safety advice is consistent on this: buy your heated throw new from a seller you trust, and avoid second-hand ones, which may be worn or may not meet current safety rules. Look for overheat protection and an auto shut-off timer as standard. If you inherit an old electric blanket, replace it if it’s around ten years old or more.
2. Check it before every season
When you bring it out for winter, lay the throw flat and look for frayed or damaged cables, scorch marks, discoloured patches, wires you can see or feel through the fabric, and a loose or damaged connector where the lead plugs in. If you spot any of these, or the controller smells hot, stop using it and contact the manufacturer.
3. Use it flat, not folded or bunched
Heated throws are designed to spread heat evenly across the surface. Folding one over on itself, wrapping it tightly round your body or bunching it up while it’s on can create hot spots. Drape it loosely over your lap and legs, keep the controller uncovered and away from the throw, and don’t put hot drinks, laptops or a hot water bottle on top of it.
4. Warm up high, then turn it down
Most throws heat fastest on the top settings. Use a high setting for the first few minutes, then drop to a low or medium setting for long sessions. Manufacturers generally recommend lower settings for prolonged use, and it’s cheaper too, because many throws draw less power on lower settings.
5. Always use the timer, and never sleep under it
Set the auto shut-off every time, even if you plan to be on the sofa all evening. Heated throws are made for the sofa rather than for sleeping under all night; if you want warmth in bed, an under-blanket designed for that job is the right tool. Take extra care with anyone who can’t easily feel heat or switch the throw off themselves, and keep it away from young children and pets.
6. Plug it in properly and unplug after use
Plug the throw straight into a wall socket where you can, rather than an overloaded extension lead. Keep the cable where nobody will trip on it or trap it under a sofa leg. When you’ve finished, switch off and unplug it at the wall.
7. Wash and store it the right way
Always detach the controller before washing, follow the care label (many throws are washed at 30°C on a gentle cycle) and let it dry completely before plugging it back in. Never dry clean a heated throw. In spring, store it flat or loosely rolled rather than tightly folded, so the heating wires aren’t creased.
How much does a heated throw cost to run?
You can work out the cost yourself in under a minute. Divide the throw’s wattage by 1,000 to get kilowatts, multiply by the hours you use it, then multiply by your electricity unit rate (it’s on your bill).
Under Ofgem’s price cap for 1 October to 31 December 2026, the average electricity unit rate for Direct Debit customers is 26.32p per kWh. A 100W throw running flat out for one hour uses 0.1kWh, so it costs around 2.6p an hour at that rate, and less on lower settings. For comparison, a 2kW portable heater uses 2kWh in an hour, which is roughly 53p. Your own tariff, region and settings will change the exact figures, so treat these as a guide.
The biggest savings come when the throw lets you keep the thermostat lower for the whole house. Warming just yourself on the sofa uses a tiny fraction of the energy needed to heat a room.

FAQ
Is it safe to leave a heated throw on all evening?
It’s fine to use one through an evening as long as you set the auto shut-off timer, use a lower setting once it’s warm and keep it flat rather than bunched up. Switch off and unplug it when you go to bed.
Can I sleep with a heated throw?
Heated throws are designed mainly for the sofa. If you want a warm bed, use an electric under-blanket made for beds and follow its instructions, usually warming the bed before you get in.
Can I use a hot water bottle with a heated throw?
No. UK safety advice is not to use a hot water bottle and an electric blanket or throw together, because of the risk of leaks and overheating.
How often should I replace a heated throw?
Replace it straight away if you see damage, scorch marks or a faulty controller. Otherwise, UK safety guidance suggests replacing electric blankets at least every ten years.
