As the festive season sweeps across the UK, there’s one tradition that never fails to spark excitement among shoppers: the Boxing Day sales. And when it comes to a retailer that truly encapsulates the spirit of British high streets, Marks & Spencer (M&S) stands tall. Known for seamlessly blending the weekly food shop with stylish homeware and wardrobe staples, M&S has long been a go-to for those seeking quality, variety, and a touch of luxury—without breaking the bank.
In 2025, the M&S Boxing Day sale is, once again, poised to be a calendar highlight for bargain hunters and loyal customers alike. According to The Independent, the retailer’s extensive range is a key draw, with past sales offering up to 50% off across fashion, beauty, childrenswear, and home categories. Whether you’re looking to refresh your work attire, restock your skincare essentials, or give your living space a January makeover, the M&S sale has traditionally covered all the bases.
This year, the Boxing Day ritual is evolving. Gone are the days of braving early-morning queues outside brick-and-mortar stores. Instead, the digital age invites shoppers to browse deals from the comfort of their own homes—pyjamas on, Christmas leftovers within arm’s reach. As The Independent notes, the 2025 M&S Boxing Day sale will launch online on Christmas Eve, giving eager buyers a head start before physical stores reopen on December 27. This shift not only makes shopping more convenient but also allows customers to make the most of their Christmas vouchers without leaving the sofa.
When it comes to finding the best deals, the experts at IndyBest recommend a bit of preparation: jot down your must-haves, filter by category on the website, and always compare prices—especially for third-party brands. Their team has spent years dissecting Boxing Day events, ensuring the discounts highlighted are genuine and worthwhile. As they put it, "we bring you details of genuine savings on products we think you’ll love."
So, what can shoppers expect from M&S this Boxing Day? If history is any guide, the deals will be wide-ranging and generous. Past sales have featured three-for-two offers on the retailer’s renowned underwear lines, two for £50 on men’s shirts, nearly 50% off bedding, and up to 40% off lamps, mugs, and home accessories. Children’s clothing has seen reductions of up to 30%, while fashion discounts have reached as high as 50% off winter boots, knitwear, and coats. Beauty enthusiasts haven’t been left out either, with brands like Color Wow and Clinique making appearances in previous M&S sales.
But you don’t have to wait until Boxing Day to grab a bargain. As of December 19, 2025, several tempting deals are already live. For the little ones, Bella Freud’s latest addition—a kids’ knitted jumper emblazoned with the slogan "star"—is crafted from thick merino wool and promises both warmth and style. It’s one of those pieces that feels special, perfect for the winter months and festive gatherings alike.
Comfort seekers will appreciate M&S’s fleece dressing gowns, which have earned a reputation for being the cosiest (and most affordable) on the high street. Now reduced to less than £25, the long robe comes with a classic tie belt and practical pockets—ideal for lazy mornings or chilly evenings. And for those who love a good scent, M&S’s TikTok-viral fragrance collection is available as a bumper set of nine eau de toilettes, currently £20 off. These fragrances have been praised for offering budget-friendly alternatives to designer scents from YSL, Chanel, Marc Jacobs, and Sol de Janeiro.
Fashionistas can also rejoice: peplum styles are dominating wardrobes as 2025 draws to a close, and one standout knitted piece—adorned with hammered gold-finish buttons and a flattering V-neck—is now available at half price. Layer it over a long-sleeved tee or under a blazer for instant New Year’s glam.
Of course, the festive season wouldn’t be complete without a box of chocolate biscuits to share (or not) during a family movie night. This year, WalesOnline conducted a thorough taste test of Christmas chocolate biscuit selection boxes from Tesco, Aldi, Morrisons, and, of course, Marks & Spencer. The verdict? M&S’s "Outrageously Chocolatey Milk, Dark and White Chocolate Biscuits" box, though the priciest at £6.50, was the clear winner in both taste and variety.
The M&S box boasts 12 varieties—more than any competitor—and includes milk, dark, white, and marbled chocolate biscuits. With 24 biscuits inside, the box’s promise of "more chocolate than biscuit" rings true. In the taste tests, M&S scored an impressive 13 out of 15, outshining Tesco (11/15), Aldi (9/15), and Morrisons (9/15). The reviewer praised the "smooth-tasting chocolate" and noted that the "biscuit had a slight festive spice flavouring to it, which stood apart from the rest." Even the clementine-flavoured biscuit drew comparisons to Terry’s Chocolate Orange, with its "sweet and tangy" profile.
While Tesco’s box offered the most biscuits (26) and was a more affordable option—especially with a Clubcard—M&S’s superior taste and variety set it apart. Aldi’s and Morrisons’ offerings, though cheaper, were described as "disappointing" in both taste and selection, with Aldi’s chocolate leaving "an odd aftertaste" and Morrisons’ orange cream biscuit "completely lacking any flavour."
The reviewer concluded, "Overall, I much preferred the Marks and Spencer biscuits. Taking price and number of biscuits inside the box into account, though, Tesco also scored very high. It was definitely a more affordable option, especially if you have a Clubcard." Yet, for those seeking a truly indulgent treat, M&S remains the gold standard.
These insights highlight what makes M&S such a beloved fixture during the holidays: a commitment to quality, variety, and genuine value. The Boxing Day sale is more than just a shopping event—it’s a tradition that brings a little extra sparkle to the season, whether you’re hunting for a new winter coat, stocking up on beauty essentials, or simply sharing a chocolate biscuit with loved ones.
With the 2025 sale set to merge seamlessly into the January event, and with deals already rolling out online, now’s the time to make your list, check it twice, and get ready for some serious savings—and maybe a few sweet treats along the way.
