Marks & Spencer has launched a major school uniform sale, offering up to 20% off on a wide range of items including blazers, trousers, skirts, and polo shirts. The promotion is available both online and in stores until August 31, 2025, helping parents prepare for the new school year without breaking the bank.
Discount Details and Eligibility
The sale applies to M&S's core school uniform range, which includes durable, easy-iron fabrics and adjustable waistbands. Customers can save 20% on selected items such as blazers (reduced from £45 to £36), trousers (from £18 to £14.40), and skirts (from £16 to £12.80). Polo shirts and other essentials are also discounted. According to M&S, the offer is available to all customers, with no minimum spend required.
How to Access the Sale
Shoppers can take advantage of the discounts by visiting M&S stores or shopping online. The promotion code is automatically applied at checkout for online purchases, and in-store prices are marked accordingly. M&S recommends checking stock availability as popular sizes may sell out quickly. The company has also extended its returns policy for school uniforms, allowing exchanges until October 31, 2025.
Additional Back-to-School Offers
M&S is not alone in offering back-to-school deals. Competitors such as Tesco, Asda, and John Lewis have also launched promotions on school uniforms and stationery. However, M&S's sale is particularly notable for its focus on quality and durability. The retailer's school uniform range is designed to withstand frequent washing and active play, with features like stain-resistant fabrics and reinforced seams.
Parents are advised to compare prices and check for additional discounts through loyalty programs or credit card offers. M&S also offers a free school uniform fitting service in selected stores, ensuring children get the right size.
