Best Electric Blankets in the UK 2026
Electric blankets remain one of the most cost-effective ways to heat a bed in the UK, particularly as energy costs have risen sharply in recent years. A modern electric underblanket costs approximately 2–5p per hour to run at full power — heating a bed for 30 minutes before sleep costs a fraction of a penny, compared to hours of central heating at far greater expense. UK winters are reliably cold enough from October to April to make an electric blanket a practical rather than indulgent purchase, particularly in older housing stock with poor insulation. The market divides into two main types: underblankets (also called heated mattress covers or bed warmers), which sit under your fitted sheet and pre-heat the mattress; and overblankets or throws, which are used on top of the duvet or for sofa use. Underblankets are the more popular choice in the UK because they warm the sleeping surface directly and can be turned off once you're in bed. Modern electric blankets are far safer than older designs: they use low-voltage heating wires with automatic overheat protection, and all sold in the UK must meet BS EN 60335-2-17 safety standards. This guide covers five of the best electric blankets available in the UK in 2026.
What to Look For
- 1Choose between underblanket (beneath the fitted sheet, pre-heats the bed) and overblanket (used on top of the duvet): underblankets are more energy efficient for pre-heating; overblankets are more flexible for sofa and bedroom use
- 2Check the heat settings: more settings give finer control — look for at least 3 settings, with the best models offering 9 or more; dual-control blankets allow each side of a double bed to be set independently
- 3Look for automatic shut-off: all reputable UK electric blankets include auto shut-off after a set period (typically 9–10 hours) as a safety feature; do not buy any model without this
- 4Verify the blanket carries a British Standards kite mark or a recognised safety certification such as BEAB Approved — this confirms it has been independently tested to BS EN 60335-2-17
- 5Check the washing instructions: most modern electric blankets can be machine washed — check the maximum temperature and whether the controller must be removed first before washing

Honourable Mentions
Editor's Note
Electric blankets in the UK should be replaced every 10 years regardless of apparent condition — the heating elements and wiring degrade over time in ways not visible to the naked eye. The BEAB (British Electrotechnical Approvals Board) marking is the most recognised UK safety certification for electric blankets; CE marking alone does not confirm product has been tested to British Standards. Before storage at the end of winter, inspect the blanket for any signs of wear, fraying, or scorch marks; do not fold an electric blanket when storing — roll it instead to avoid kinking the heating elements. Never use an electric underblanket with an electric adjustable bed unless the blanket is specifically rated for use with adjustable bases, as repeated folding damages standard blanket wiring.
