Amazon's self-heating blanket that 'doesn't cost a penny to use' back in stock for £38

With the freezing temperatures set to continue in the weekend and the latest Ofgem price cap increasing household bills by up to £150 in 2025, there’s never been a more vital time to invest in home essentials that keep you warm. One incredibly popular product, known as the Silentnight self-heating blanket, previously sold out completely at Amazon, but it has just come back in stock at two retailers - and it doesn’t cost a penny to run.

Unlike electric blankets that cost a few pence an hour to stay powered, this Silentnight self-heating blanket uses a heat reflecting foil layer to keep you nice and toasty when bundled up. A super-fluffy sherpa lining keeps the blanket comfortable, making it perfect for these freezing winter nights.

The blanket previously sold out completely at Amazon, but it’s recently come back in stock for customers to purchase once again for a price of £37.99. It’s also available at Sleepy People if you’re looking for an alternate way to pick it up.

Ideal for curling up on the sofa, keeping warm in bed during cold nights, or draping over your lap while working from home, the Silentnight blanket is fully machine washable, ensuring it stays fresh throughout the season. This feature is particularly useful for households with children or pets.

An ideal solution for staying warm without racking up the heating bill - the self-heating throw is said to be 'warm, cosy and worth the price'. The only colour option is a dark grey but that should effortlessly complement any decor when artfully draped over a chair or layered on the bed. If you're after another colour, consider Dunelm's Silky Soft Faux Fur Throw that comes in orange, pink or black for £55.
