'Gluten free' on UK menus: what the claims mean when eating out

Published 30 October 2026

“Gluten free”, “very low gluten” and “no gluten-containing ingredients” are not the same words. In England, Northern Ireland and Wales, the Food Standards Agency’s technical guidance says the rules for “gluten-free” and “very-low gluten” apply to all food, including a restaurant meal. This page is about those words. It does not replace the NHS, your GP, your dietitian or an allergy action plan. The kitchen note is gluten and coeliac disease when eating out.

Coeliac disease and a wheat allergy

The NHS describes coeliac disease as an autoimmune condition. The immune system attacks your own tissues when you eat gluten, which damages the gut so you cannot properly take in nutrients. Gluten is a protein in wheat, barley and rye, and coeliac disease affects at least 1 in every 100 people in the UK. Allergy UK says it is not an allergy or an intolerance. The technical guidance says the reaction is not the same as an allergic reaction, and that people with coeliac disease will not go into anaphylactic shock. The NHS says there is no cure, and that a gluten-free diet should help control symptoms. The treatment page says you are referred to a dietitian when first diagnosed. Speak to your GP before you change what you eat.

A wheat allergy is separate. The NHS lists wheat among the foods that most often cause allergic reactions, and says to tell restaurant and café staff. Allergy UK describes an IgE-mediated wheat allergy as a reaction to proteins in the wheat grain, which can include anaphylaxis. Your doctor or dietitian advises whether you also avoid rye, barley and oats. A gluten-free line does not answer that question.

The cereals a business must name

Cereals containing gluten are one of the 14 allergens. GOV.UK lists wheat, rye, barley and oats. The technical guidance names wheat, including spelt and Khorasan, plus rye, barley, oats and their hybridised strains. Spelt and Khorasan are wheat. They are not suitable substitutes for people with coeliac disease or a wheat allergy, and a reference to wheat is still required, for example “spelt (wheat)”. See the 14 allergens UK restaurants must declare.

GOV.UK says a restaurant must tell you if food contains any of the 14 allergens. Check the menu, call ahead, and ask again when you arrive, including if the ingredients changed. You can ask for another dish. They do not have to cook one. For loose food, the best-practice note says written information should name the specific cereal, and an allergen symbol needs the allergen name with it or a key that names it. The allergen guidance says written information plus a conversation works best.

“Gluten free” and “very low gluten”

The technical guidance says voluntary “gluten-free” and “very-low gluten” statements must meet Regulation (EU) No. 828/2014. In the food as sold to the final consumer, “gluten-free” means no more than 20 mg/kg of gluten, and “very-low gluten” means no more than 100 mg/kg. The NHS states the gluten-free rule as no more than 20 parts per million (ppm). It says these trace amounts will not cause a problem for most people with coeliac disease. Your doctor or dietitian decides whether that applies to you. No other statement may describe the absence or reduced presence of gluten. Food that contains oats specially produced, prepared or processed to reduce gluten can still use either statement if the rules are met, but the cereal must be indicated and emphasised.

A gluten-free statement is not an absolute claim. It stipulates gluten below 20 mg/kg. The allergen guidance says a free-from claim needs strict controls of ingredients, handling and preparation. If the kitchen uses wheat flour and cannot keep it apart in time and space, it should tell you, and it should not make a gluten-free or wheat-free claim. The best-practice note says the menu must show whether the cereal is in the dish or the dish is free from it.

“No gluten-containing ingredients”

“No gluten-containing ingredients”, often shortened to NGCI, is not “gluten-free” or “very low gluten”. The technical guidance says NGCI statements can mislead. They have been used for dishes that leave gluten-containing ingredients out, when the business cannot guarantee the food is gluten-free. Best practice is to avoid them, and to use “gluten-free” where strict controls keep the food to no more than 20 mg/kg of gluten. If NGCI is still used, the business should say the food is not suitable for people with coeliac disease.

Cross-contact

The NHS says cross-contamination can happen if gluten-free food and food that contains gluten are prepared together or served with the same utensils. The allergen guidance says gluten-free chips cannot be cooked in oil already used for battered fish. If that risk stays, the business should tell you it cannot provide an allergen-free dish. The PAL guidance names food touching, shared boards, a shared fryer and flour in the air.

“May contain” beside a gluten-free line

The consumer advice says there is no specific legal requirement to print “may contain”. The PAL guidance says to use it only when a risk assessment finds a risk that cannot be removed, and that “may contain allergens” can mislead because it names nothing. On loose food, staff can say it instead. The technical guidance allows “gluten-free” beside “may contain wheat”. Its example is barley cross-contamination tested below 20 mg/kg, which can still be a risk if you are allergic to other proteins in that cereal. Ask which cereal. See “may contain” labels.

What to ask

The NHS treatment page says that with coeliac disease you stop eating barley, rye and wheat, including spelt, cous cous, semolina, durum and bulgar. Unless a food is labelled gluten-free, that includes bread, pasta, cakes, pies, gravies and sauces. Malt flavouring and modified food starch can contain gluten, so read the label. The overview says most beers are made with barley. Allergy UK lists battered or breaded fish and meat, soya sauce, gravy and stock cubes among foods which contain or may contain wheat.

The NHS says oats do not contain gluten, but they can cause a reaction if produced with wheat, barley or rye, and a small number of people with coeliac disease react to pure oats. The treatment page says to discuss oats with your healthcare professional. If you include them, choose oats labelled gluten-free, and ask which product the kitchen uses.

• Is there wheat, rye, barley or oats in the dish, sauce, gravy, stock, batter or soya sauce?
• Do you mean gluten-free, very low gluten, or no gluten-containing ingredients?
• What else used this oil, fryer, toaster or board?
• Has the recipe changed, and who checked?

The consumer advice says to ask whether they offer a suitable meal, whether they can make one, how the food is handled, and whether equipment or ingredients could cross-contaminate it. They must give you allergen information. They do not have to offer another meal. On arrival, mention glazes, garnishes, sauces and oils. If you doubt they understand, do not eat there. The wording is in how to tell a restaurant about your food allergy.

Food packed before you choose it

Food packed on site before you choose it is prepacked for direct sale. The Food Standards Agency calls these rules Natasha’s Law. From 1 October 2021, the consumer advice says, the label needs a full ingredients list with allergens emphasised, and the label does not replace a conversation. GOV.UK says the name of the food should be there too. A boxed sandwich is a different case from a plate, and a takeaway needs allergen information before you buy and again when it arrives. Natasha’s Law and PPDS labelling is the longer account.

A search starts the question

A search chooses where to ask. It does not clear a kitchen. You can search for restaurants for a food allergy and search on the SafePlate homepage. Searching SafePlate is free. Record gluten, and record coeliac disease as well if that is your diagnosis. Bristol and Liverpool say who covers food businesses locally. The allergy-friendly restaurant guides collect those pages.

The usable allergy chef card, in 38 languages, is part of SafePlate Plus. The allergy chef card page is a preview. On the free site you see that preview only. It is not filled in with your foods, and you cannot hand it over or print it as your card.

Set up your foods before you search. This is not medical advice. Confirm the meal with the kitchen. In the UK, if you think someone is having anaphylaxis, call 999.
