Comparison: Best Electric Over Blanket Double (Updated | Dec 17th)

An electric over blanket is a thick, fleecy blanket that lies on top of you for direct warmth, similar to a regular duvet. An electric under blanket, or mattress protector, is fitted to your mattress and heats the bed from below. Over blankets are generally more flexible and can be used on the sofa, while under blankets provide consistent, all-night warmth from underneath.

Prioritise models with overheat protection, which automatically shuts the blanket off if it gets too hot. A detachable controller and fully machine-washable blanket are essential for easy cleaning and maintenance. Ensure the product has a clear safety certification, such as a UKCA or BEAB mark, indicating it meets strict safety standards.

Most quality double over blankets offer dual controls, allowing each person to set their own preferred temperature and timer. Look for at least three to six heat settings to provide enough flexibility for different levels of cold. A digital controller with a timer function is a valuable feature for energy efficiency and peace of mind, allowing you to set it to switch off automatically.

The material affects both comfort and heat retention. Fleece and plush polyester are popular for their softness and excellent insulation properties. For a more luxurious feel, consider a blanket with a cotton or microfibre top layer. Check the care instructions to ensure the material is durable enough for regular machine washing.

No, they are generally very energy-efficient and cost much less to run than central heating. A typical double over blanket uses very little power, often costing just pennies per night to run on a low setting. Using the timer to heat the bed for an hour before sleep and then switching to a low setting or off is the most cost-effective method.

Always check the manufacturer’s instructions, but most modern blankets are designed for easy care. You must first detach the controller and all cords before washing. Most can be machine washed on a gentle, cool cycle and should be air-dried or tumble-dried on a low heat setting, as high heat can damage the internal wires.

For a standard double bed (135cm x 190cm), you should look for a blanket specifically labelled as ‘Double’. It’s wise to check the exact dimensions of the blanket to ensure it provides adequate coverage and drape over the sides of your mattress. Some brands offer ‘Super King’ size blankets which can provide extra width and luxury on a double bed.

The main differences lie in features, materials, and build quality. Premium models often have more heat settings, ultra-fast heat-up times, and more advanced digital controllers with timers. They also tend to use softer, higher-quality materials and may offer a longer warranty for greater peace of mind.
