UK School Nut Policies: Everything Parents Need to Know
Last updated: April 2026
If your child has just brought home a letter telling you to keep nuts out of the lunchbox, you might assume there is a national school nut ban in the UK. There is not. No piece of legislation, no Department for Education rule and no Food Standards Agency regulation tells schools to ban nuts. What every state-funded school in England has, from September 2026, is a legal duty to publish its own allergy policy under Benedict's Law — and that policy can allow nuts, restrict them, or do something in between.
Around one in 50 UK children has a peanut or tree nut allergy, according to Allergy UK. That is one or two children in the average class of 30. The school's job is to keep those children safe without giving the rest of the class the false impression the building is somehow nut-free. The result is a patchwork of "nut aware" policies and packed-lunch guidance that genuinely varies school to school — and is about to be more consistent than it has ever been.
Here is what UK schools can and cannot do about nuts in 2026, what Benedict's Law actually changes, and what to send in the lunchbox if your school has asked you to keep nuts out.

Is there a nationwide school nut ban in the UK?
No. There is no UK-wide ban on nuts in schools. What schools do have is a duty under section 100 of the Children and Families Act 2014 to support pupils with medical conditions, including food allergies, and to have proper arrangements in place for them. How each school chooses to meet that duty has, until now, been almost entirely up to the head and the governing body.
That is why two children at primary schools five miles apart can come home with very different lunchbox letters. One school operates a strict no-nuts-in-the-building approach, written into the home-school agreement and enforced from reception upwards. The next is a much softer "we have children with allergies on roll, please take care with what you send in" letter, with no formal ban at all. Both are legally fine.
What is changing is consistency. From the start of the 2026/27 academic year, every maintained school and academy in England has to publish a whole-school allergy policy. The policy itself can still allow or restrict nuts on a school-by-school basis — but every school now has to have one, in writing, that parents can read.
What Benedict's Law changes from September 2026
Benedict's Law is named after Benedict Blythe, a five-year-old who died from anaphylaxis at his primary school in 2021. After a sustained campaign by his family and by the allergy charities, peers in the House of Lords voted in February 2026 in favour of an amendment that committed the government to introducing mandatory statutory allergy guidance for English schools.
From September 2026, every maintained school and academy in England has to:
- publish a whole-school allergy policy
- hold an individual healthcare plan for every pupil with a known allergy
- complete mandatory allergy awareness training for all staff
- keep in-date generic adrenaline auto-injectors on site for emergencies
The full statutory guidance is being consulted on and published in summer 2026, ahead of wider implementation in September. Importantly, the guidance does not require schools to be "nut free." Allergy UK, Anaphylaxis UK and the British Society for Allergy and Clinical Immunology have all consistently argued against blanket bans — the claim is impossible to enforce and gives parents and staff a false sense of security. The focus is whole-school awareness, individual risk assessments and a properly rehearsed emergency response. Scotland, Wales and Northern Ireland have their own arrangements; the English guidance is the most significant change to allergy management in UK schools in a generation, and the other nations are watching.
"Nut aware" vs "nut free" — what your school is probably doing
Most UK primary schools sit in one of two camps.
Nut aware (also called allergen aware)
The school does not claim to be nut free. There are children with allergies on the register, each one has an individual healthcare plan, staff are trained, and parents are asked to take reasonable care with what they send in. Risk is managed through awareness, not through a written ban. This is the position Allergy UK and Anaphylaxis UK both recommend for schools with mixed-age children.
No nuts in the building
A softer version of a school nut ban: the school explicitly asks parents not to send in nuts, peanut butter, hazelnut spreads (Nutella is the one named most often) or other nut-based products. The school still does not promise the building is nut-free, because it cannot. This approach is most common in nurseries and infant classes, where children are too young to manage their own risk.
"Nut free school" — the wording charities push back on
A small number of schools still describe themselves as nut free. Allergy charities push back hardest against this wording, because it cannot be guaranteed. A child can bring in a granola bar with traces of hazelnut without anyone noticing; a packed lunch can be made on a kitchen counter that had peanut butter on it that morning. The safety comes from awareness and a working emergency plan, not from the absence of every nut on the premises.
What schools can — and cannot — ask you not to send in
Most school packed-lunch policies share the same shortlist. In a nut-aware school the items most often flagged are: peanuts and tree nuts in any form, peanut butter, hazelnut chocolate spread, nut-based granola bars, trail mix, satay sauces, and cakes or biscuits with visible nuts.
Schools cannot search a child's lunchbox, confiscate food or refuse to let a child eat what they have brought in unless their behaviour policy is very specific about it. What they routinely do is contact parents and ask for a swap. If your child has been asked not to bring something in, that is the school using its policy, not national law.
Schools have more direct authority over food prepared on-site. School kitchens follow food safety regulations, manage allergens for pupils with confirmed allergies, and serve menus that meet the school food standards.
How to find out your school's nut policy
Three places to look first.
- The school website. Most schools publish their allergy policy and packed-lunch guidance in the parent information or policies section. Search the site for "allergy", "nuts" or "packed lunch."
- The induction pack from when your child started. Allergy and lunchbox guidance is usually one of the first things schools share with new families.
- The SENCO. If you cannot find it in writing, the SENCO (Special Educational Needs Co-ordinator) manages individual healthcare plans and will know exactly what the school's position is.
From September 2026, every English state-funded school is required to publish its allergy policy. If yours has not published one and the autumn term has started, ask — the whole-school policy is mandatory, not optional.
What an Individual Healthcare Plan actually does
If your child has a confirmed nut allergy, the most important document in their school life is the IHP. An Individual Healthcare Plan is drawn up jointly by the parents, the school and (where relevant) a clinician. It records the allergy, the trigger foods, the warning signs, the emergency action plan and the medication that needs to be on site. The British Society for Allergy and Clinical Immunology publishes free allergy action plan templates that GPs and consultants can fill in.
The plan should be reviewed at least once a year and any time your child's situation changes — new diagnosis, new medication, new school year. Under Benedict's Law, holding an up-to-date IHP for every pupil with a known allergy is a statutory requirement, not a courtesy. If the school does not have one for your child by the end of the first half-term, that is the question to put to the SENCO.
A nut-aware packed lunchbox: what to send instead
The good news is that the spreads aisle is in a much better place than it was three years ago. There are now several genuinely nut-free chocolate spreads on UK shelves, plus a wider range of seed butters, dairy dips and sweet alternatives that work in a sandwich without a nut anywhere near it.
The ground rule: look for spreads made in a dedicated nut-free factory, not just spreads with no nuts in the ingredients. Our complete guide to nut-free spreads in the UK covers every brand on the shelf, including the JimJams 1kg School Compliant tub designed for exactly this situation. For a deeper dive on why sunflower seed butter has become the default nut-free swap, our comparison of sunflower seed butter and peanut butter walks through the nutrition.
Beyond the spread, a nut-aware lunch can lean on hummus, cream cheese, jam, banana, mashed avocado, marmite, lean meats and tinned fish. Seed-based granola bars are easy to find, but check the back of the pack for "may contain" lines if your school's policy is strict. For a full week of ideas, our nut-free lunchbox ideas guide covers five days of swaps that kids will actually eat.
Frequently asked questions
Is there a UK law banning nuts in schools?
No. There is no UK-wide school nut ban. From September 2026, every state-funded school in England has to publish an allergy policy under Benedict's Law, but the policy itself can choose to allow or restrict nuts. The decision sits with the head and governing body, not with the Department for Education.
What is Benedict's Law?
Benedict's Law is the statutory allergy guidance for English schools that comes into force in September 2026, named after Benedict Blythe, a five-year-old who died from anaphylaxis at his primary school in 2021. It requires every school to publish an allergy policy, hold individual healthcare plans for pupils with allergies, train all staff in allergy awareness and keep in-date adrenaline auto-injectors on site.
Why don't allergy charities recommend full nut bans?
Allergy UK and Anaphylaxis UK advise against schools claiming to be "nut free" because the claim cannot be enforced — staff cannot check every lunchbox, every snack and every cake brought in for a birthday — and the wording gives parents and children a false sense of security. The recommended approach is a whole-school awareness culture combined with individual risk assessments.
Can a school confiscate a peanut butter sandwich?
Schools cannot search a child's lunchbox unless their behaviour policy specifically allows it. What schools routinely do is contact parents to ask for a swap. If your child's school has asked you to keep nuts out of the lunchbox, that is the school using its own policy, not a piece of national law.
My school does not have an allergy policy yet — what should I do?
From September 2026, every English state-funded school is legally required to publish an allergy policy. If yours has not, ask the SENCO or head teacher when it will be in place. Allergy UK, Anaphylaxis UK and BSACI all publish free model policies that schools can adapt, so there is no shortage of starting points.
