Choose a flavoured crisp for a gluten-free diet by checking the exact pack for a clear gluten-free claim, then reading its ingredients and precautionary allergen statements. Coeliac UK warns that seasonings can contain wheat flour or barley malt extract, while a “may contain gluten” statement signals a cross-contamination risk. A potato base or familiar flavour alone does not establish suitability.
If you want a flavoured variety, check its seasoning, gluten-free claim and precautionary statements rather than relying on the potato base. Coeliac UK notes that flavoured seasonings can contain wheat flour or barley malt extract.
A gluten-free claim does not settle whether a flavour suits someone avoiding milk, soya or celery. The ingredient information for Seabrook Cheese & Onion, KETTLE Sour Cream & Sweet Onion and REAL Roast Ox illustrates why the exact flavour matters.
Salt & Vinegar or Cheese & Onion is not a suitability category. Walkers Salt & Vinegar carries a precautionary statement for wheat and other cereals containing gluten, so check the current pack even when the flavour is familiar.
Start with the claim on the exact flavour, then read the seasoning ingredients and allergen statements. Check other allergens separately if they matter to your household.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten-free assurance | Look for a gluten-free claim on the exact product. Check whether a recognised assurance mark applies to that pack, rather than assuming it covers every flavour. | I want a clear signal for the flavour I am buying. In Coeliac UK’s Shopping Habits 2025 survey of 3,785 members, 74% of respondents trusted its Crossed Grain Trademark more than a gluten-free statement; that figure measures trust, not crisp suitability. |
| Seasoning ingredients | Read the full ingredient list, including flavouring components, for wheat or barley. Coeliac UK notes that wheat flour and barley malt extract can be used in crisp seasonings. | A potato-based crisp appeals to me, but I need to know what is in its flavouring before choosing it for a gluten-free diet. |
| Precautionary statements | Check for “may contain gluten” and related cereal warnings. Coeliac UK says such a statement identifies a cross-contamination risk considered by the manufacturer. | Even if I do not spot wheat in the ingredients, I want to avoid treating a gluten precautionary warning as assurance of suitability. |
| Other allergens | Check the exact flavour for milk, soya, celery and any other allergens relevant to you. Read its ingredients and precautionary information separately from its gluten-free claim. | Gluten is not the only ingredient I need to consider when choosing cheese, cream or savoury flavours for my household. |
Coeliac UK notes that flavouring can include wheat flour or barley malt extract. The potato base does not establish the suitability of the finished crisp.
Read the seasoning ingredients and look for a clear gluten-free claim on the exact pack.
Coeliac UK describes this statement as a cross-contamination warning. Walkers Salt & Vinegar and McCoy’s Salted are product examples with gluten-related precautionary information.
Do not treat a familiar flavour or an ingredient list without an obvious gluten cereal as a reason to disregard the warning.
KETTLE Sour Cream & Sweet Onion and Seabrook Cheese & Onion have gluten-free statements but contain milk ingredients. REAL Roast Ox also lists milk, soya and celery in its flavouring.
Check each additional allergen you need to avoid against the current ingredients and precautionary information.
Tyrrells Sweet Chilli & Red Pepper and Sea Salt & Cider Vinegar have different ingredient and allergen information; the latter lists barley malt vinegar.
Use brand information to identify products to examine, then make the decision from the current pack for the exact flavour.
These brand statements and product examples help narrow the label checks; they do not replace the information on the pack you buy.

KETTLE Chips states that its Sea Salt & Balsamic Vinegar and Sour Cream & Sweet Onion products are gluten-free.
REAL states that its crisp range is gluten-free. Treat this as the manufacturer’s range claim and check the product you intend to buy.
Tyrrells flavours need individual assessment for gluten-free shopping rather than a brand-level assumption.
Assess Walkers flavoured crisps by the exact product’s ingredient and precautionary statements.
McCoy’s Salted and Cheddar & Onion product information calls for pack-level checking by anyone shopping for a gluten-free diet.

No. Coeliac UK explains that the statement identifies a cross-contamination risk considered by the manufacturer. An ingredient list without an obvious wheat ingredient does not cancel that warning.
The Food Standards Agency states that food labelled “gluten-free” must contain no more than 20 mg/kg of gluten as sold to the final consumer. The claim does not mean the food is free from other allergens.
Yes. KETTLE Chips identifies its Sour Cream & Sweet Onion flavour as gluten-free but lists milk ingredients; Seabrook Cheese & Onion also contains milk. Check milk suitability independently of the gluten-free claim.
