Best electric blankets & heated throws UK (2026)

Heating the person instead of the house is the cheapest warmth there is — 1p–4p an hour against 50p+ for a plug-in heater. Here’s how to choose, and six picks from brands that pass the safety testing.

TL;DR

For the sofa, get a heated throw (~3p/hour) — the Silentnight Comfort Control is the safe default, the Bauer is the value pick. For bed, get an underblanket (~1p–2p/hour) — Silentnight’s double for most people, a dual-control king if you and your partner disagree about temperature (everyone does). Always buy from a brand with UKCA marking and overheat protection; this is not the category for the cheapest thing on the page.

Throw or underblanket? Pick by room, not by price

A heated throw is a normal fleece blanket with fine heating wires through it — you wrap it round yourself on the sofa, and it moves wherever you do. An electric underblanket straps to the mattress under your bottom sheet and turns a cold bed into a warm one before you get in. Throws run 100–160W; underblankets 60–100W. At the current ~26p/kWh cap that’s 3–4p an hour for a throw and 1–3p for an underblanket — and both cycle off once warm, so real-world usage is lower still. An evening under a throw costs less than boiling the kettle twice.

The honest sequencing for a cold house: blanket first, thermostat second, heater last. If everyone’s under a throw by 8pm, the heating can go off an hour earlier — that’s where the real saving lives, and it’s why we treat this page as the first purchase on the site, not an accessory.

Heated throws — for the sofa (and everywhere else)

#1 Best throw for most people

Silentnight Comfort Control Heated Throw (120×160cm)

Silentnight is the brand the group tests keep coming back to, and this is their standard-setter: stitched channels to prevent hot spots, Heatsafe overheat protection, and a proper fleece that’s pleasant even unheated.

The 2-hour auto shut-off is the right kind of nannying — it covers the fall-asleep-on-the-sofa case that causes most electric blanket accidents.

#2 Value pick

Bauer Professional Heated Throw (120×160cm)

Regularly the cheapest name-brand throw with a full-length timer — the 1–9 hour range means it works as a bed overblanket on a schedule, not just a sofa wrap.

The detachable controller turns it into an ordinary throw for summer, which is the difference between a gadget and a blanket you own for years.

#3 Bigger & smarter

Minky Luxury Heated Blanket (180×135cm)

The pick if two of you share a sofa blanket — the extra width matters more than any spec. Minky’s thermostat also genuinely cycles: it stops drawing power at temperature and only reheats when it cools.

Quoted running cost is ~4p/hour flat out; in practice the cycling brings a warm evening in well under that.

£39.99

Electric underblankets — for the bed

#1 Best underblanket for most

Silentnight Comfort Control Electric Blanket (Double)

The classic. Pinsonic channels keep the wires flat and evenly spaced, the straps actually hold it in place, and it pre-warms a double bed in minutes for pennies.

Put it on when you head up to brush your teeth; the bed is warm when you are. That habit alone lets most people drop the bedroom radiator entirely.

#2 Budget bed warmer

EMtronics Heated Underblanket (Double)

Does the one job — warm bed, cold room — at the lowest sensible price with the safety basics (overheat cut-off) present. Thin wires you can’t feel through a sheet.

No timer, so it’s a switch-on-then-off-at-bedtime blanket rather than a schedule-it one. At this price, fair trade.

£18.99
#3 King & couples

Dreamcatcher Fully Fitted King with Dual Control

Two controllers, one per side — the feature that ends the thermostat war. Fully fitted like a sheet, so it stays put on a king mattress instead of migrating.

Each side heats independently; one of you can run setting 3 while the other switches off entirely.

£49.99

The safety bit (read this one)

Electric blankets are involved in around 40 UK house fires a year, and almost all involve blankets that are old, damaged, creased into storage folds, or bought unbranded. The rules that matter: buy UKCA/CE-marked brands with overheat protection; check each autumn for scorch marks, frayed fabric or exposed wire; never use with a hot water bottle; don’t tuck a throw in tightly or pile heavy things on a running blanket; and replace after ~10 years. Everything on this page has overheat protection and auto shut-off as standard.

Frequently asked questions

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

Very little. A heated underblanket draws 60–100W, so an evening hour costs roughly 1p–3p at around 26p/kWh. A heated throw draws 100–160W — about 3p–4p an hour. Warming the person, not the room, is the cheapest heat in the house.

What is the difference between an electric blanket and a heated throw?

An electric (under)blanket fits on the mattress under your sheet and pre-warms the bed. A heated throw is a normal soft blanket with heating wires, used on the sofa or over you in bed. Throws are the more versatile buy; underblankets make cold bedrooms civilised.

Can you leave an electric blanket on all night?

Only if the manufacturer explicitly says so — look for all-night or timer-controlled models. Most makers recommend switching off or using the auto-off timer once you're in bed. Never use one with a hot water bottle, and replace any blanket with visible wear or scorch marks.

Are electric blankets safe?

Modern UK-sold blankets with overheat protection, auto shut-off and UKCA/CE marking are very safe when used per the instructions. The fires that do occur are overwhelmingly from old, damaged or misused blankets — replace every 10 years and check for scorching or frayed fabric each autumn.
