School Uniform Sale Dates 2026

Whether you're buying for primary or secondary school, uniform costs can really add up.

According to moneysavingcentral.co.uk's predictions, here's what's coming up:

Don't forget — there are other great ways to save on school uniform too. Preloved clothing sites such as Vinted, eBay, and Facebook Marketplace often have secondhand uniforms at a fraction of the price. Many schools also hold uniform swaps at the end of the year — a brilliant way to pick up nearly-new items for free. Don't forget your local charity shops too!

If you have a loyalty card with any of these retailers, make sure you have it handy at the till to make the most of any extra points or rewards on offer!
