Sustainable school uniform: the rule change that just widened the market
Laura Turner (owner & editor) at CWB flagged this one to me when I last spoke to her, and the more I looked at it the more I thought it deserved your attention. From the start of the September 2026 school year, state-funded schools in England can require no more than three branded uniform items. Secondary schools get a fourth only if one of them is a tie, and PE kit counts towards the limit. The aim is to bring the cost down for families, and it will. But it lands hard on the schoolwear specialists who built their businesses on badged items, and the Schoolwear Association has warned that small family-run firms are genuinely at risk. Supermarkets and the high street stand to pick up the share. That is the honest picture, and anyone selling you this as an unqualified good news story is not telling you the whole of it.
Here is the part almost nobody in our industry has noticed. Cap the compulsory branded items at three and the rest of the uniform becomes un-badged. Un-badged means the parent chooses, rather than the school's nominated supplier choosing for them. For the first time, fabric, durability and provenance become buying decisions in a category that has been a closed procurement loop for decades. That is a market opening, and it opens in September. One caveat worth saying out loud, because it keeps the rest of this honest: polyester is in school uniform for real reasons, not just commercial ones. It is hard-wearing, easy-care and affordable, and for a garment worn five days a week by a seven-year-old those are genuine virtues. Any brand competing on natural fibre has to beat polyester on durability and care, not just on conscience.
So who is actually making sustainable school uniform? The business I would point you at is One+All. A Stockport company that started in 1935 as a family knitwear manufacturer, they became 100% employee owned in 2015 and the first B Corp in the schoolwear market in 2020. Their current B Corp score is 136, against a pass mark of 80, and it is independently reassessed every three years, which matters more than any claim a brand makes about itself. Their purpose is written down as growing for the greater good, and the numbers behind it are not decorative. Accredited Living Wage employer since 2018 and Living Hours since 2022. An 8% employer pension contribution. A 2025 profit share of £3,750 per colleague. A founding member of the Greater Manchester Good Employment Charter, mentoring other local businesses through it. More than half of what they make relies on cotton fibre, and in 2025 they sourced 73% of it as Better Cotton, against a target of 50%. They also helped fund a 131Kw solar system at their exclusive supplier partner's factory in Bangladesh, and they publish their supply chain mapping and an annual human rights report rather than asking you to take their word for it.
Then there is the part that ties all of this back to the rule change: what happens when the uniform is outgrown. Citing independent research by My Nametags, One+All point out that 1.4 million wearable school uniform garments are thrown away every year. They give their retail customers up to five free recycling units so schools can start collecting preloved uniform, and they have teamed up with Barnardo's, Cancer Research UK, Sue Ryder and The Salvation Army so what comes back is either passed on to families who need it or recycled. That matters right now, because alongside the branded-item cap the statutory guidance expects schools to make second-hand uniform genuinely available rather than treat it as an afterthought. Uniform is already the most circular thing in a child's wardrobe. Barnardo's research found the average UK garment is worn about seven times, while the average school uniform garment is worn over 300. The infrastructure to close that loop is being handed to schools this term, and the manufacturers who already built it are the ones schools will lean on.
FREQUENTLY ASKED QUESTIONS
What are the new school uniform rules from September 2026?
Under the Children's Wellbeing and Schools Act 2026, state-funded schools in England cannot require a pupil to have more than three different branded uniform items. Secondary schools may require a fourth only where one of those items is a tie. Branded means anything carrying the school or trust name or logo, and anything that is only available from a particular supplier because of its colour, design or fabric. PE kit counts towards the limit. Extra branded items can still be offered, they just cannot be made compulsory.
Do the new uniform rules apply across the whole UK?
No. This measure applies to state-funded schools in England only. Scotland, Wales and Northern Ireland set their own uniform policy, so if you supply across the UK you will be working to different rules in different nations. Worth checking before you rewrite your range plan or your marketing.
Why is so much school uniform made from polyester?
Because it works. Polyester is hard-wearing, holds colour, washes at low temperatures, dries fast and costs less, all of which matter for a garment worn five days a week and washed constantly. That is why the category leans on it, and why a natural-fibre alternative has to compete on durability and easy care rather than on values alone. The more interesting question is usually not how to remove polyester but how to keep the garment in use for longer and give it somewhere to go at the end, which is where resale, take-back and recycling routes do more good than a fibre swap on its own.
