Dedicated kitchen versus gluten-free options: what to ask when you eat out

A dedicated gluten-free kitchen is one that does not cook wheat, barley or rye as part of ordinary service. Gluten-free options are dishes made without gluten ingredients in a kitchen that also handles gluten. Both can matter when you eat out. They are not the same thing.

If you have just been diagnosed with coeliac disease, or you are keeping a booking you made before you knew, that difference is often the first practical problem. A menu marked GF tells you about ingredients. It does not, on its own, tell you how the food was fried, toasted or plated.

Coeliac UK (opens in a new tab) describes coeliac disease as a serious autoimmune condition, not an allergy or a food intolerance. When someone with the condition eats gluten, the immune system attacks the lining of the gut. The charity says 1 in 100 people in the UK have coeliac disease, but only 36% are diagnosed, leaving 500,000 people who have it and do not yet know. The only treatment is a strict gluten-free diet for life.

Why a shared kitchen can still be a problem

Gluten does not need to be listed as an ingredient in your dish to cause trouble. Coeliac UK's advice on cross-contamination (opens in a new tab) is written for home kitchens, but the same risks show up in restaurants, hotels and work buffets: crumbs in shared spreads, a toaster used for ordinary bread, or a fryer that has already cooked battered food.

The charity's eating-out guidance (opens in a new tab) also tells people to check whether a separate fryer is used for gluten-free options, to speak to a manager so the request is treated as a health necessity rather than a preference, to confirm the order before eating, and not to eat the meal if they are still in doubt.

None of that means a shared kitchen can never get it right. Many do, with training, separate equipment and clear processes. It does mean you should ask how the food is prepared, not only whether a dish is listed as gluten-free.

What gluten-free means in UK law

In the UK, the words "gluten free" are regulated. Coeliac UK explains (opens in a new tab) that only foods containing 20 parts per million (ppm) or less of gluten can be labelled gluten-free. That law became mandatory in January 2012. The charity says this is a safe level for people following a gluten-free diet. The term can apply to specialist products such as breads and flours, including those made with gluten-free wheat starch, and to uncontaminated oat products.

The same threshold applies to food sold in catering, not only to supermarket packets. Coeliac UK's commercial guidance on gluten-free law (opens in a new tab) says a business needs to be able to prove that a product labelled gluten-free contains no more than 20ppm, in restaurants as well as in pre-packed food.

That is why the exact wording matters. The same page notes Food Standards Agency guidance on precautionary allergen labelling: businesses are advised not to use "no gluten containing ingredients" statements, and to use a "gluten free" claim instead, because that claim reflects controls that keep gluten at or below 20ppm. If a business still uses a "no gluten containing ingredients" statement, Coeliac UK says it should make clear that those foods are not suitable for people with coeliac disease.

A "may contain" warning is a separate issue. Coeliac UK says a food can in some cases be labelled both "gluten free" and "may contain wheat", which is aimed at people with a wheat allergy and can be confusing. The gluten-free claim should not be compromised, and the food is still expected to contain no more than 20ppm of gluten.

There is also a legal "very low gluten" label for certain specialist products with between 21 and 100ppm of gluten. Coeliac UK says foods are not currently labelled that way in the UK.

What the 100 Club means

On this site, the 100 Club means one thing only. The venue's own website says the kitchen or the menu is fully gluten-free, and we can point you to that page. It is not a review score, and it is not the same as a gluten-free pizza sitting beside wheat bases.

That is a higher bar than "we have options". It is also not a guarantee. We do not inspect kitchens, and we are not Coeliac UK. Staff and suppliers change, so you should still speak to the venue before you order. Our London 100 Club guide lists the London places we have checked against that rule, with sources and the date we last read them.

If you need a meal where gluten is not part of ordinary service, start there. If you are relying on options instead, the questions below are how you check the kitchen on the day.

Coeliac UK accreditation is not a dedicated kitchen

Coeliac UK runs Gluten Free Accreditation (opens in a new tab), which it describes as the only gluten-free scheme of its kind in the UK. It has been running since 2012. Being accredited means the venue and its staff have been through audits and training against the charity's gluten-free standards.

That is a strong trust signal for gluten-free options, not automatically a dedicated kitchen. Coeliac UK's pages for venues and caterers (opens in a new tab) say the accreditation trademark covers the gluten-free options on a menu, and that the scheme helps businesses meet the 20ppm rule when they serve those meals. An accredited restaurant may still cook wheat for other customers.

At accredited venues, Coeliac UK says you will not see disclaimer statements on menus, and that staff have been trained to follow the correct procedures. Staff can still change, so the usual questions help. Its Venue Guide (opens in a new tab) is for members.

In January 2026, the charity said more than 3,000 UK venues were Gluten Free Accredited. We treat that public badge as useful extra information, not as a substitute for the 100 Club, and we do not copy the members-only list.

Questions to ask in a restaurant

Coeliac UK's eating-out tips make a clear script. Use them in your own words.

Before you go, or when you book:

• Please may I speak to a manager or the chef about coeliac disease?
• Do you have a dedicated gluten-free kitchen, or gluten-free options in a shared kitchen?
• How do you avoid cross-contamination? Do you use a separate fryer for gluten-free food?
• Can you prepare this as gluten-free, to the 20ppm standard, rather than simply leaving the bread off?

When you arrive:

• I have coeliac disease. This is a medical need, not a preference.
• Please tell the kitchen before the food is prepared.
• Which dishes can you make safely today?

When the food arrives:

• Please can you confirm this is the gluten-free order?
• If anything still feels uncertain, do not eat it. Coeliac UK gives the same advice.

The Food Standards Agency says that, by law, UK food businesses must tell customers if they use any of the 14 regulated allergens. Those allergens include cereals containing gluten, namely wheat, rye, barley and oats. For restaurant and takeaway meals, which count as non-prepacked food, that information can be given in writing or verbally. FSA research published in 2025 (opens in a new tab) explains that legal duty, and current best practice: written allergen information that is easy to get, backed up by a conversation.

You are entitled to ask, even if the menu already has a GF mark. A symbol is about ingredients. The conversation is about how the dish will be cooked today.

Hotels, breakfasts and work events

The same distinction shows up away from restaurants. Hotel breakfasts often involve shared toasters, shared spreads and buffets where crumbs travel. Work lunches are often ordered by someone who does not eat gluten-free themselves. Coeliac UK says its accreditation scheme is also used in hospitality, education and healthcare catering.

A short written note to the organiser or hotel helps:

• I have coeliac disease and need food that is gluten-free, not only food without obvious pasta or bread.
• Please confirm who is catering, and whether they can prepare a gluten-free meal to the 20ppm standard.
• Please ask how they handle fryers, breakfast toast, spreads and buffet service.
• Please send me the allergen information. Food businesses must provide information on the 14 regulated allergens.

If the answers are vague, treat the meal as uncertain. Eat beforehand if you can, or look for a dedicated kitchen nearby. In London, that is what the London 100 Club guide is for.

Before you go

Menus, staff and suppliers change. We last checked the official sources linked here on 11 November 2026.

This page is not medical advice, and it is not a substitute for Coeliac UK. If you are newly gluten-free at home as well, The Gluten-Free Starter Pack is planned as a practical bundle with a shopping list, label notes and a few recipes.

FAQ

What is the difference between a dedicated gluten-free kitchen and gluten-free options?

A dedicated kitchen does not handle gluten as part of ordinary service. Gluten-free options are dishes made without gluten ingredients in a kitchen that also cooks gluten. The second can be done carefully, but it depends on process, training and the details on the day.

What does gluten-free mean on a UK menu or label?

Coeliac UK says only foods with 20 parts per million of gluten or less can be labelled gluten-free. That threshold applies to packaged food and to food sold in catering. A phrase such as "no gluten containing ingredients" is not the same claim.

Is Coeliac UK accreditation the same as a 100 Club kitchen?

No. Accreditation means a venue has been audited and trained against Coeliac UK's standards for serving gluten-free food. The charity says the trademark covers the gluten-free options on the menu. The 100 Club is only for venues that say the whole kitchen or menu is fully gluten-free.

What should I ask in a restaurant if I have coeliac disease?

Ask to speak to a manager or the chef, say that this is a medical need, and ask whether the kitchen is dedicated or shared. Check the fryer and other shared equipment, and confirm the order before you eat. If you are still unsure, Coeliac UK says not to eat the meal.

Do I still need to mention coeliac disease if the menu says gluten-free?

Yes. The FSA says you should be able to get allergen information, and Coeliac UK recommends explaining the need clearly and confirming the order. A menu mark does not tell you what happened in the fryer or on the pass that day.
