Tweedmill Pure New Wool Block Check Blanket review
By Tom Calder
A good pure new wool blanket is one of the most reliable ways to stay warm if the heating fails, holding its insulating power even when slightly damp and needing no power at all. It is heavier and pricier than a foil blanket, but a British-made one lasts decades and earns its place in the airing cupboard.

What we like
- Keeps you warm even when damp, is naturally breathable and is slow to ignite, so it is more forgiving than synthetics if you are heating a room by other means.
- Genuinely durable, lasting decades with basic care, so it doubles as everyday bedding rather than kit that only appears in a crisis.
- No batteries, power or setup, and works the instant you need it.
Worth knowing
- Bulky and heavy, so it belongs at home rather than in a grab bag or car kit.
- Quality British wool is not cheap, and coarser weaves can feel scratchy for sensitive skin unless you choose a softer lambswool or merino.

Our review
The Tweedmill block check throw is a 100% pure new wool blanket woven in Flint, north Wales, about 150 by 183 cm including the fringe. It needs no power, keeps working when slightly damp and is slow to catch fire, which makes it the most dependable warm layer in the house when the heating is off. The trade-off is weight, bulk and a cold-wash-only care label.
What it is
Tweedmill Textiles weaves this throw at its mill in Flint, Wales, from 100% pure new wool, in a two-tone block check with a fringed edge. Retailer listings give the size as about 150 by 183 cm including the fringe, which is enough to cover an adult on a sofa or lie across a double bed. Tweedmill does not publish a weight, and the care instruction is a cold wash only; most owners will spot clean and air it instead.
There is nothing to charge, switch on or run out. That is the whole point of a wool blanket in a preparedness kit: it is the layer that still works at three in the morning on the second night of a power cut.
Why wool, not fleece
Wool behaves differently from synthetic fibres in a cold, damp room. The Woolmark Company's fact sheet explains that wool can absorb up to 35% of its weight in moisture before it feels wet, and that as it absorbs it releases heat, "keeping the wearer feeling warmer and drier in cold damp conditions." Wool is also naturally slow to ignite and tends to smoulder rather than flare, which matters if you are heating a room with candles or a stove during an outage; our guide to candles in a power cut covers the fire risks.
A good wool blanket also lasts for decades with basic care, so it can be ordinary bedding rather than kit that only comes out in an emergency. The NHS and ambulance services advise several thin layers over one thick one when it is cold; a wool throw over a duvet, or over a thermal base layer, is exactly that.
How it compares
On the keeping warm page the puredown feather and down throw is lighter and lofts more, but down loses its insulation when wet and needs careful washing. A heated throw is warmer still but useless once the power goes. The Blizzard survival bag packs far smaller for a grab bag but is single-use. A hot water bottle under the wool throw is the combination that most households will reach for first.
Our verdict
Buy one per sofa or bed if your house loses heat fast and you have anyone vulnerable to the cold. Skip it for a grab bag or a car kit, where a foil blanket or bivvy bag does the job at a fraction of the weight, and skip it if anyone finds wool itchy, in which case a lambswool or merino throw is kinder on skin. Air it in spring, store it with a moth deterrent, and it will outlast most things in the cupboard.

Who shouldn't buy this
Don't buy this for packable warmth in a grab bag or car — a compact foil or synthetic emergency blanket is far lighter, cheaper and better suited to that. Wool is for staying put and staying warm at home.

Is the Tweedmill blanket made in the UK?
Yes. Tweedmill Textiles weaves it at its mill in Flint, north Wales, from 100% pure new wool.
How big is it?
About 150 by 183 cm including the fringe, according to retailer listings. Tweedmill does not publish a weight.
Can I machine wash a pure new wool throw?
The care instruction is a cold wash only. A gentle wool cycle in cold water with wool detergent is safest; hot water or a tumble dryer will felt and shrink it.
Does wool really keep you warm when damp?
The Woolmark Company says wool absorbs up to 35% of its weight in moisture before feeling wet and releases heat as it does so. It will not keep you warm if soaked, but it copes with a damp room far better than cotton or down.
