The cheapest electric blanket found at the supermarket: what they offer.

According to The Sun: If you are trying to reduce your utility bills but don't want to freeze on autumn nights, an electric blanket could be your lifeline.

This week, we reviewed prices at major supermarkets and found a leader with the lowest prices on double options.

There is a suitable option for both a sofa and a bed.

Among the blankets for a double bed, the most affordable offer is from Morrisons - just £20, which is more than five pounds cheaper than the equivalent from Tesco.

The cheapest option: Morrisons for £20

Fine Elements heated blanket (double)

At Morrisons supermarket, the Fine Elements electric blanket (double) is offered for £20 - this is the lowest price for a double electric blanket this week.

The Fine Elements model has three temperature settings, a removable controller for convenient machine washing, elastic straps for securing to the mattress, and built-in overheat protection.

The power of this blanket is 70 W, providing quick heating and maintaining a stable temperature thanks to the built-in thermostat.

Why this is a great purchase for £20

• Three temperature levels provide easy control
• The removable controller allows you to wash the blanket in the machine
• Elastic straps prevent the blanket from slipping under the sheets
• Overheat protection and thermostat control for your peace of mind
• 70 W power for quick heating on cold nights

At this price, it's a great addition to your central heating - perfect for warming the bed before sleep and then turning off when you feel comfortable.

Best alternatives at Tesco and Asda

Tesco electric blanket, £25.25

Tesco is offering a double blanket through its marketplace for £25.25 this week.

It is made of 100% polyester, has three temperature settings, overheat protection, and a removable control for machine washing. The power of the model is 60 W, and its dimensions are 120 cm by 107 cm.

If you need a slightly less powerful option but with basic control, this is a decent purchase, although it is more expensive.

Slumberdown Cosy & Snug heated blanket, £40 (save £10) at ASDA

If you need a versatile option for both a sofa and a bed, the Slumberdown heated blanket will be a real discovery.

It has 10 temperature settings, a timer, a long 3 m cord, and a soft two-sided finish (sherpa on one side and silky fleece on the other).

Moreover, you can remove the cord and use it as a regular blanket.

This is not a fitted blanket, so it cannot be secured to the mattress, but it will be an excellent choice for lounging, working from home, or using on the couch.

What to know before purchasing

• Fitted vs. blanket: Fitted blankets (Morrisons, Tesco) are secured to the mattress and heat the surface of the bed. Blankets (Asda) are meant to be used on top - ideal for sofas and layering, not for a fitted bed.
• Temperature settings and timers: Three settings are simple and convenient for most sleepers. If you want precise heat control and automatic shut-off, the 10 temperature settings and hour timers on the Slumberdown blankets are the most advanced.
• Washing and care: Check for a removable controller - the Morrisons and Tesco models can be machine washed after removing the controller.
• Safety: Look for overheat protection as a standard feature. All three options have it. Always follow the manufacturer's instructions and do not use electric blankets with damaged cords or with certain medical devices unless recommended.

If you want to save on heating and just need a warm bed, buy the double blanket from Morrisons for £20 while it's available - it will fully meet the needs of most.

If you are looking for a comfy companion for the sofa or home office, the blanket from Asda with many features will be worth the expense.

Tesco offers a decent option if Morrisons runs out in your area.
