Martin Lewis shares energy-saving hack that could slash bills this winter

Martin Lewis has urged viewers to carry out a simple five-minute check that could save them hundreds of pounds on their energy bills this winter. The MoneySavingExpert founder shared the advice during the latest episode of his ITV programme, The Martin Lewis Money Show Live, as he tackled growing concerns about soaring household costs. Lewis told viewers the key to saving money this winter is getting off what he jokingly calls the "pants cap" - officially the Energy Price Cap. He explained: "For all but those on pre-payment meters, where sadly there's little choice, I'd urge people to get off the Cap, use a whole-of-market comparison site to find their cheapest fix.

"That will instantly cut people's bills." The finance expert warned that many households have become "complacent" on the capped rate, wrongly assuming it's the cheapest option. In reality, he said, switching to a fixed deal can often save hundreds - particularly for those willing to compare across the entire market rather than sticking with their current supplier.

Martin added: "While I'm urging people to do a comparison right now, as savings are potentially large, for those on a Price Cap tariff currently, it's important for people to be aware that sites will show your savings compared to the current Price Cap."

He said many comparison sites now show real-time savings estimates, allowing users to see how much they could cut from their bills instantly.

For most households, the process takes just five minutes and could reduce annual energy costs by hundreds of pounds - especially before the winter chill fully sets in.

"Between the 1st October and the 31st December, the energy price cap is set at £1755 per year for a typical household," he said.

"However, some energy companies are offering tariffs that are up to 18% cheaper than the cap, which would mean up to £315 off your annual price cap bill."

Lewis, who founded MoneySavingExpert.com, regularly warns consumers that small checks like this can make a big difference over the course of the year.

The 52-year-old presenter said it's vital to take advantage of current fixed-rate offers before prices shift again.

He reminded billpayers that pre-payment meter customers sadly have fewer options, but those paying by direct debit or on credit meters can often find meaningful savings by switching now.

The latest Energy Price Cap, set by regulator Ofgem, limits how much suppliers can charge for each unit of gas and electricity, but it does not cap total bills. Prices are still affected by overall usage - meaning anyone on the cap can still end up paying more if they use more energy.

Martin's final piece of advice was clear: take five minutes to check, compare, and switch if possible. As he's long warned viewers, "doing nothing" is often the most expensive choice of all.
