As a deep freeze grips the nation, UK households are seeking smart ways to stay warm and dry without sending their energy bills soaring. Condensation and mould become common battles in wintery conditions, but a device endorsed by Money Saving Expert founder Martin Lewis is set to offer a solution at a bargain price.
Why Martin Lewis Calls It a 'Savvy Swap'
Martin Lewis has frequently highlighted the benefits of dehumidifiers on his ITV show and BBC Sounds podcast. He champions them as a far cheaper alternative to using a tumble dryer for drying laundry indoors, labelling high-wattage dryers as costly "demon appliances".
He explains that while a tumble dryer can cost around £1 per cycle, a typical 200W dehumidifier runs for roughly 7p per hour. With the current Ofgem price cap setting the average electricity cost at 27.69p per kWh until March 2026, the savings are clear. Lewis describes the switch as a "savvy swap" for reducing moisture, preventing mould, and keeping energy costs low.
Aldi's Budget-Friendly Winter Warmer Range
This Sunday, 11th January 2026, Aldi launches its latest SpecialBuys 'winter warmer' collection. Alongside heated airers and draught stoppers, the star appliance is the Aldi Midi Dehumidifier, priced at £89.99.
The supermarket claims the unit can extract up to 12 litres of moisture per day, aiding in "speedy drying" and managing air humidity. It features a two-litre tank, adjustable settings, a 24-hour timer, and a quiet mode. For convenience, it also has wheels, a touch-screen display, and a drainage hose for continuous use.
A Timely Solution for Cold Homes
With snow affecting much of the UK and Ofgem's price cap recently inching up, Lewis's advice is more pertinent than ever. Using a dehumidifier to dry clothes and control damp can be a key strategy for cutting household costs during the coldest months.
While Martin Lewis does not endorse specific brands, Aldi's entry into the market provides a competitively priced option for shoppers looking to act on his expert money-saving tip this winter.
