Martin Lewis says 3p per hour device 'on sale' at Asda for £18 keeps you toasty as temperatures drop

Martin Lewis says 3p per hour device 'on sale' at Asda for £18 keeps you toasty as temperatures drop Personal finance guru said some people who can't afford to keep their heating on at all need to consider how to heat their bodies up directly Personal finance expert Martin Lewis has urged people who are being hit with serious financial issues - to the point they can’t put their heating on - to consider a 3p-an-hour gadget. On his Money Show Live this week, Mr Lewis had experts in to discuss the current energy price crisis. The Ofgem Energy Price Cap currently stands at £1,723 per year for a typical dual-fuel household paying by Direct Debit (October 1 to December 31, 2026), which is a 4% (£60) increase from the previous quarter driven largely by high Middle East wholesale gas prices. However, major hikes are projected for early 2027: forecasts warn that the cap could jump significantly—by roughly 27% to 29%—taking the typical annual bill toward £2,187 to £2,215 from January 2027 onward if wholesale pressures persist. Viewer Cass said: “I don’t put my heating on at all. I simply cannot afford it.” Mr Lewis said that the fuel price situation has not yet hit the worst: “That’s before the 27% hike. And I think this is a real societal problem rather than just a money-saving problem. First thing I’d say is speak to your energy firm. They may well have grants or help or support, especially if you’re struggling and it’s going to be too cold to survive. If you have to: heat the human, not the home. I’m not saying you should do this. I’m saying we’re talking desperation stakes.” Mr Lewis said people could use electrical warming devices - which actually cost very little an hour - but instead of heating up a room or whole house. For example, he advised people to use an electric blanket, saying it’s 3p an hour. Asda do a Silentnight Winter Nights Electric Blanket currently on offer for £18, down from £30. He said: “ So, layered clothing—an inner layer, a mid layer, an outer layer that can keep you warm. Lots of different layers on top when you’re in the house. Put a hot water bottle in a sleeping bag. Sleep in that. Very well insulated. Make sure the hot water bottle isn’t scalding. It sounds weird. It’s true, isn’t it? Put your feet up. The coldest part of your house is the floor. So, have your feet on a table. It’s not quite as cold.” "But also about heating you. If you can’t put the central heating on: heated gloves, insoles, electric gilet—£12 to £30 quid. Plug in USB. Less than a penny an hour. Keeps you warm. Very localised heating. You’re not even heating the room, which is, you know, normally the cheaper way. "We heat the house. No, you just heat the room. No, we just heat the person. A microwave heat bag costs less than a penny to put it in the microwave and keep you warm. A hot water bottle boiled in the kettle is about 5p for a one-off. Stays warm if it’s well insulated. Make sure you know you’re putting a bit of cold water in so it’s not boiling. An electric blanket plugged into the mains is less than 3p an hour to run. Make sure you’re not sleeping in it unless it’s one that can be slept in at night." Ensure our latest money headlines always appear at the top of your Google Search by making us a Preferred Source.

He said: “We need to maintain some background heat in the house just to avoid any sort of condensation or damp in other areas of the property. Definitely protecting your house is important, but ultimately at desperation stakes, it’s not as important as protecting yourself. “I don’t want to be saying this, but I’m saying this. Listen, you might also find, “Hey, during the day I’m in by myself, I don’t want the central heating on, I like my heated gloves, and that works fine, and it can help me cut the cost.” All of that is wonderful, but when we get to the extreme point it is a problem. But I thought it was important back to that time to mention it, I’m afraid.”
