What the law says about gluten free labelling in the UK


Fast Facts:
⚡ Under UK law, food products must clearly identify any of the 14 major allergens, including gluten
⚡ If gluten is present in any form (Barley, Rye, Oats, Wheat) it must be clearly listed and emphasised such as being in bold, contrasting colours or underlined
⚡ Precautionary allergen labelling (PAL) should also be included if there is a risk of cross-contamination
⚡ Products labelled as ‘Gluten Free’ must undergo testing and contain less than 20ppm of gluten
⚡ Failure to comply can result in fines, product recalls, or other legal actions
⚡ Not all countries follow the same standards and regulations
📃 Allergen Identification Requirements
In the UK, allergen labelling is governed by both UK and retained EU legislation (which still applies in some cases even after Brexit, but UK-specific changes may occur over time) with updates from the Food Standards Agency (FSA). Any of the 14 major allergens must be clearly declared, regardless of how small the amount used.

🔎 Gluten Labelling Requirements
If a product contains any form of gluten (wheat, barley, rye, oats), the ingredient must:
- Be clearly listen in the ingredients list
- Have the allergen emphasised each time it appears (e.g. bold, underline, or contrasting colours🌈)
Many products also include an Allergen Advice Statement, but it isn't always an indication of whether that item does or doesn't contain gluten.
"Allergen advice: for allergens including cereals containing gluten, see ingredients in BOLD."
🧪 Gluten Free Labelling Standards
In order to be labelled as 'Gluten Free' or have a gluten free symbol, including the crossed grain symbol, a product must:
- Contain less than 20 parts per million (ppm) of gluten
- Meet the Codex Alimentarius standard for gluten free foods
- Be suitable for most people with coeliac disease r gluten intolerance

⚠️ Cross-Contamination & Precautionary Labelling (PAL)
When there's a risk of cross-contamination during production, manufacturers are encouraged to use Precautionary Allergen Labelling, such as:
"May contain gluten"
PAL should only be used when a real risk is present and must align with FSA guidelines. For people with coeliac disease, even tiny traces of gluten can cause harm, so products with 'may contain gluten' warnings should be avoided.

⚖️ Legal Enforcement
The Food Standards Agency (FSA) and Trading Standards enforce food labelling laws in the UK. They:
- Monitor and inspect manufacturers
- Investigate complaints and unsafe products
- Can issue fines, demand product recalls, or take other legal actions if allergen labelling laws are breached
🌍 International Labelling Differences
Allergen labelling laws differ worldwide:
- 🇦🇺 Australia - Zero-tolerance policy - gluten free means no detectable gluten
- 🇺🇸 USA - Focusses on wheat labelling, not all gluten sources
- 🇨🇦 Canada- Similar to the US, with some wheat-specific rules
Products labelled 'gluten free' abroad might not meet UK standards, so always check the label when travelling or ordering from overseas. Check out our Country guides for help label reading when travelling abroad.
🎯 Quick Recap
In the UK, food labelling laws are designed to protect consumers, especially those with allergies or coeliac disease. Allergen information must be clear and easy to find, with strict standards around gluten content for 'gluten free' claims. Understanding the rules - and how to read labels - empowers you to make safe, informed food choices, no matter where you shop.
