A single electric blanket warms your bed before you get in, and it is one of the cheapest ways to feel warm at night because it heats the bed rather than the whole room.
Prices checked on Amazon UK, 27 October 2026.
A single electric blanket warms your bed before you get in, and it is one of the cheapest ways to feel warm at night because it heats the bed rather than the whole room. Most single underblankets are smaller than the mattress, typically around 135 x 65cm to 150 x 80cm, and tie on with straps; fully fitted versions cover the whole mattress with an elasticated skirt. The details that matter are the number of heat settings, whether there is a timer or automatic shut-off, and whether you can machine wash it with the controller removed. This guide compares single underblankets from Morphy Richards, Silentnight, Dreamland and others, with every spec taken from the Amazon UK listing. Sharing a bed?

How much does a single electric blanket cost to run?
Electric blankets use little power compared with a heater. To work out the cost, divide the wattage by 1,000 and multiply by the hours of use and by the unit rate on your electricity bill; a 60W blanket on full for one hour uses 0.06kWh. Several listings, including Silentnight and Morphy Richards, claim running costs from about 1p per hour; those figures are the brands' own and depend on the setting and your tariff.
A timer, like those on the Morphy Richards (£29.99), TOPS (£29.89) and Dreamland (£59.99) blankets, means you can warm the bed and let it switch itself off.
What to look for in a single electric blanket
Size and fit. Underblankets that tie on are smaller than the mattress; fully fitted blankets cover it all. A standard UK single mattress is 90 x 190cm, so compare that with the size in the table.
Timer or auto shut-off. Electrical Safety First advises switching the blanket off before you sleep unless it has an automatic shut-off.
Heat settings. More settings give finer control; the Morphy Richards lists 9 and the Dreamland 6.
Washing. Most listings say the blanket is machine washable once the controller is detached. Check the wash temperature.
Safety marks. Look for overheat protection and approvals such as BEAB on the listing, and register the blanket with the maker.
Never with a hot water bottle. Electrical Safety First warns against using a hot water bottle and an electric blanket together.
How we chose these picks
We only included products that were in stock on Amazon UK with a single live buy-box price in pounds when we checked on 27 October 2026, read with a UK delivery address. We skipped listings showing low stock, no stock line or unclear details, and we avoided repeating products already featured in our other guides. Specs in the comparison table come from each product's Amazon UK listing, and a dash means the listing does not state that detail. Descriptions are based on what each listing says; we have not tested these products ourselves, and we have not used star ratings or review counts.

Frequently asked questions
What size is a single electric blanket?
Single underblankets in this guide range from 135 x 65cm to 150 x 80cm and sit on the mattress under your sheet. Fully fitted single blankets cover the whole mattress; the Dreamcatcher fully fitted blanket measures 193 x 91cm according to its listing.
How much does a single electric blanket cost to run?
Divide the blanket's wattage by 1,000, then multiply by the hours you use it and your unit rate per kWh. A 60W blanket uses 0.06kWh in an hour on full. Silentnight and Morphy Richards claim from about 1p per hour on their listings.
Can a single electric blanket be used on a double bed?
It will fit, but it will only warm the part of the bed it covers, so it suits one sleeper. If two people want heat, a double blanket, ideally with dual controls, is a better choice.
What is the lifespan of an electric blanket?
Electrical Safety First recommends replacing an electric blanket every ten years, and sooner if the fabric is worn, there are scorch marks, wires are visible or the control buzzes or smells.
