Eating out with a peanut allergy in the UK
Published
Eating out with a peanut allergy in the UK means treating peanut as its own food, saying the word, and getting an answer about the actual dish. Peanuts are one of the 14 allergens businesses must tell you about. The Food Standards Agency’s entry for peanuts describes them as a legume that grows underground, which is why the same food is called groundnut. It names biscuits, cakes, curries, desserts, sauces such as satay, groundnut oil and peanut flour as places peanuts are used. This article is the practical version of that list for a restaurant, a cafe and a takeaway. It is not permission to eat any particular meal, and it is not a substitute for your own allergy plan or your doctor.
Chris Faulkes, who built SafePlate, is anaphylactic to peanuts. That is why a peanut allergy is not a footnote on this site. It does not make a kitchen safe, and it does not tell you how your own body will react. If you think someone is having anaphylaxis, the NHS says to call 999. The steps are in what to do if you have an allergic reaction in a restaurant.
Peanut is not the tree-nut list
UK allergen law lists peanuts separately from tree nuts. The tree nuts named in the rules are almond, hazelnut, walnut, cashew, pecan, Brazil nut, pistachio and macadamia. A kitchen that has removed walnut has not, by that fact, removed peanut. “Nut allergy” is easy for two people to hear as two different lists. We say peanut, and we say groundnut as well if the menu uses that word. If you also avoid tree nuts, say those names too. The peanut allergy eating-out guide and the tree nut guide are written as a pair for that reason.
Lupin is another legume. Some people with a peanut allergy are also told to avoid it, and many are not. GOV.UK notes that lupin includes lupin flour. If your specialist has told you to avoid lupin, ask about flour in pastries and gluten-free bakes, and use the lupin guide. If they have not, do not invent a new ban at the table from a general article. Sesame is a separate allergen again. It matters on buns and in tahini, and it has its own sesame guide. A peanut question does not cover it.
Where we ask about peanut
Satay is the obvious sauce. The misses are the garnish on a salad, the chopped nuts on a pudding, the biscuit base under a dessert, and the oil in a fryer. Groundnut oil is peanut oil. The legal category in the non-prepacked guidance is “peanuts and products thereof”. Unlike fully refined soybean oil, which is a stated exception under soya, that peanut entry does not list a refined-oil exception. So we ask which oil they cook with, and what else is cooked in it. We do not decide from the word “vegetable”.
Whether highly refined peanut oil is a problem for you is a clinical question. Restaurants use different oils, and an article cannot see the bottle. Do not treat this page as clearance to eat food cooked in groundnut oil. Ask what they are using. If they do not know, choose something else or leave. The Food Standards Agency says that if you doubt the staff understand your allergy, do not eat there.
The same applies to peanut flour in a bake, and to a curry or stew where the peanut is in the sauce rather than on top. A menu title can say “salad” and still send the leaves out with a peanut dressing. Ask about the dressing, the garnish and the pan, not only the main word on the menu.
What to say, in a UK restaurant
The Food Standards Agency’s ordering advice is the spine of the conversation. Call ahead if you can. Be clear that it is a peanut allergy, and give examples: satay, groundnut oil, peanut flour, chopped peanut as a garnish. Ask whether they can offer a suitable meal. If they cannot, ask whether they can prepare one. Ask how food is handled, and whether a fryer, board or sauce could cross-contaminate the plate. Ask if the recipe has changed. They must give you allergen information. They do not have to invent a new dish.
When you arrive, say it again to the person serving you, and ask them to check with the kitchen rather than reading the menu title back to you. Remind them about oils and garnishes. There is a fuller version of this conversation, for any allergen, in how to tell a restaurant about your food allergy.
- Is there peanut, groundnut, satay or peanut flour in this dish, the sauce or the garnish?
- Which oil are you cooking with, and what else is cooked in it?
- Are peanuts stored or chopped near this meal?
- Has anything been substituted today?
- Please tell me what the kitchen said after they checked.
“May contain peanuts” is a voluntary precautionary warning. The Food Standards Agency says there is no specific legal requirement to use that wording. If it is there, read it as a warning about cross-contamination, not as a dare. If it is not there, you still ask about the fryer. Silence is not a dedicated kitchen.
Packed food is a different label from the plate
If you are buying food that was packed on the premises before you chose it, such as a boxed sandwich, Natasha’s Law means you should see a full ingredients list with peanut emphasised if peanut is an ingredient. That is the grab-and-go counter. It is not the steak cooked after you order. A takeaway has to give you allergen information before you pay and again when the food arrives. If you are ordering for a table, ask them to mark the container that was made for the peanut allergy, so it is not handed to the wrong person in the hallway.
What a search can and cannot tell you
You can search for restaurants for a food allergy with peanut on your list, and you can search on the SafePlate homepage. Searching SafePlate is free. Places come from public map data. An allergy score stays unknown until a menu or a visitor note mentions the food. Unknown means the file is empty. It does not mean the kitchen has been cleared, and it does not mean the kitchen is unsafe. It means you still have the conversation above.
The usable allergy chef card, in 38 languages, is part of SafePlate Plus. Free use of the site includes a preview of the allergy chef card, with sample wording, not a card filled in for you and not a card you can print as yours. A card the kitchen has not read does not change the pan. Someone still has to check the dish and tell you what they found.
The questions do not change between cities. What changes is who you would contact if the information was wrong, and where emergency departments are. The guides for London, Manchester, Birmingham and Bristol cover that local picture. None of them names a restaurant as safe for a peanut allergy. If you were given wrong or missing allergen information, report it to the local food safety team after you are safe, not instead of getting medical help.

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.
