M&S Slashes 20% Off 'Warmest' Duvet Coat, Now £88 in Winter Sale
M&S cuts 20% off popular Thermowarmth Duvet Coat

As the UK braces for another deep freeze, Marks & Spencer has delivered a timely winter warmer for shoppers, slashing the price of one of its most acclaimed coats.

The Deal: 20% Off a Winter Essential

Marks & Spencer has reduced the price of its popular Thermowarmth Quilted Duvet Coat by a significant 20%. The discount, active from 13th January 2026, brings the cost down from the original £110 to a much more accessible £88. However, retail experts warn that high demand means popular sizes are selling rapidly.

Why This Coat Is So Highly Rated

Designed for the harshest British weather, the coat features a generously padded, duvet-like design complete with a comfortable hood and advanced thermal insulation. It incorporates M&S's proprietary Stormwear technology, making it water-repellent and ideal for sudden winter showers.

The product has earned an impressive average rating of 4.8 stars from M&S customers. One enthusiastic reviewer stated it was the "warmest jacket I've ever owned", adding they constantly recommend it to friends and family. Another praised its practical length, useful hood for dog walking, and spacious pockets.

Considerations and Alternatives

While feedback is overwhelmingly positive, it's not universal. One customer noted an issue with the collar, finding it restrictive when the hood was down. For those seeking other options, the market offers alternatives like the Next Shower Resistant Padded Hooded Coat at £65 or the ASOS DESIGN oversized fleece-lined raincoat, currently on sale for £54.

This strategic price cut from M&S provides a compelling opportunity for consumers to invest in high-quality, weather-ready outerwear at a reduced cost, just as the season's coldest temperatures take hold.
