Owen's Law: the case for written allergen information on menus

Last updated: April 2026 · ~9 min read

Owen's Law is a proposed UK reform that would make it legally required for hospitality venues serving non-prepacked food to provide allergen and ingredient information in writing at the point of order, not just verbally when a customer remembers to ask. It is backed in principle by the Food Standards Agency, but it is not yet law. This guide explains where it stands, what it would require, and why forward-thinking operators are adopting it early.

1. What Owen's Law would require, in one paragraph

For any food that is not prepacked (the plate you cook to order, the buffet dish, the canapé at a wedding, the set menu at an event), Owen's Law proposes a binding obligation that the venue display written allergen and ingredient information on the menu (or on a directly linked written medium) at the moment the customer chooses what to eat. Verbal assurance from a server, however confident, would no longer be sufficient on its own. The 14 regulated allergens would be the same list already used for prepacked food and under Natasha's Law.

2. Why it exists

The law is named after Owen Carey, who died on his 18th birthday in April 2017 after a severe dairy reaction to a grilled chicken burger at a Byron Burger restaurant in London. Owen told staff about his allergy and asked about allergens, but he was not told that the chicken had been marinated in buttermilk. Verbal Q&A at the table failed. Owen's family, led by his sister Emma Kocher and his father Paul Carey, launched the Owen's Law campaign to close the exact gap that killed him: reliance on spoken information in a noisy restaurant, under time pressure, with no written backup the diner can see.

3. Where the reform stands today

• April 2017 Owen Carey dies on his 18th birthday after an allergic reaction to buttermilk-marinated chicken.
• 2019, inquest Coroner issues a Prevention of Future Deaths report highlighting the inadequacy of verbal-only allergen information.
• December 2023, FSA Board vote The Food Standards Agency Board formally voted in favour of recommending that written allergen information be provided in non-prepacked settings, aligning the FSA with the Owen's Law position.
• 2024, government engagement Defra and the FSA opened consultation / call-for-evidence on mandatory written allergen information for non-prepacked food. Industry adoption accelerates ahead of any statute.
• Today Owen's Law is FSA-supported best practice, not statute. Major chains and independents are adopting written allergen disclosure voluntarily, and local authority Environmental Health Officers routinely reference it in inspections as the expected direction of travel.

4. How Owen's Law relates to Natasha's Law

These two reforms are not in competition, they complete each other. Together, they would cover every way food reaches a customer in the UK.

For catering operators, the practical implication is simple: the recipe that underpins your PPDS label is the same recipe that will underpin your Owen's Law menu disclosure. If your recipe book is accurate and live, you are already most of the way there. If it is a patchwork of spreadsheets and chef memory, you will be rebuilding it under pressure when the law lands.

5. The 14 allergens, same list as Natasha's Law

Owen's Law would use the same 14 allergens that are already regulated under the Food Information Regulations 2014 / retained Regulation (EU) 1169/2011:

• Celery
• Cereals containing gluten
• Crustaceans
• Eggs
• Fish
• Lupin
• Milk
• Molluscs
• Mustard
• Peanuts
• Sesame seeds
• Soybeans
• Sulphur dioxide & sulphites
• Tree nuts

6. What "written information at the point of order" actually looks like

Watch out: verbal assurance alone, even confident, well-trained verbal assurance, is specifically what Owen's Law is designed to move beyond. Staff should point to the written source and confirm, not replace it.

7. Why adopting Owen's Law early is a business decision, not a compliance one

• Guest trust scales. Written disclosure reduces anxiety for allergen-aware diners, and that cohort is growing. Venues that publish their matrix openly convert better with higher- spending groups (family parties, corporate events, weddings).
• Liability exposure drops. Coroner reports and civil cases have repeatedly highlighted verbal-only allergen information as a failure mode. A dated, live, written disclosure is the single most defensible artefact your ops team can produce.
• Menu changes stop being risky. If your allergen matrix is generated from your recipes, a supplier spec change that adds celery to a gravy updates the matrix automatically, not three weeks later when a guest is hospitalised.
• You beat the rush. Operators who wait for legislation will have four to eight weeks to rebuild their menus, train staff, and print materials. Operators who adopt early treat it as a design choice and do it once, calmly.
• The EHO already expects it. Many local authority inspectors already reference Owen's Law in inspections as the expected standard. Meeting the letter of Natasha's Law plus the spirit of Owen's Law is the safer posture.

8. Operational checklist for venues

1. Hold a canonical recipe for every dish, with compound ingredients (sauces, stocks, marinades) broken down to allergen level.
2. Map each recipe to the 14 allergens plus any "may contain" cross-contact risks you genuinely cannot control in your kitchen.
3. Generate the customer-facing allergen matrix from that recipe database, not from a separate document that can drift.
4. Publish the matrix in one of the three FSA-aligned patterns (menu icons, physical matrix, QR code to a live page).
5. Re-run the matrix every time a supplier changes a spec or a chef edits a recipe. Keep a dated archive so inspectors and incident reviews can reconstruct what was on the menu and when.
6. Train front-of-house to point to the written source, confirm the guest has seen it, and escalate any ambiguity to the kitchen lead, never to "best guess".
7. Treat "vegan", "gluten-free" and "dairy-free" menu claims as separate flags, not synonyms for allergen safety.

9. Where Havenue fits in

Havenue was built for the world Owen's Law is pointing towards. The Safety Engine maps every ingredient in every recipe to the 14 regulated allergens, keeps your allergen matrix in lockstep with your recipe book, and regenerates the customer-facing documents (allergen-annotated menus, kitchen-ready event orders, PPDS labels) the moment anything changes upstream.

When Owen's Law becomes statute, the operators running on Havenue will not be rebuilding anything. They will be printing an up-to-date matrix that has always been there. That is the point.
