Choose afternoon crisps by the particular allergen or dietary requirement you need to check, rather than assuming that plain, potato-based or vegan crisps are free from it. For gluten avoidance, Seabrook and REAL state that their crisp ranges are gluten-free, while KETTLE labels individual products such as Thai Sweet Chilli gluten-free. Milk, soya and precautionary allergen statements still vary by flavour, so check the current packet before choosing.
Look for an explicit gluten-free statement on the crisp you plan to buy, rather than relying on its potato base. Seabrook states that its crisps and snacks are gluten-free and Coeliac UK accredited; REAL makes a gluten-free claim for its crisp range, while KETTLE labels individual flavours.
Read the ingredients and any precautionary statement for the exact flavour. The Food Standards Agency explains that wording such as “may contain” communicates possible unintended presence of a regulated allergen; a gluten-free claim does not settle a milk or soya requirement.
Check both claims on the particular product, then read its ingredients for other allergens that matter to you. KETTLE Thai Sweet Chilli, for example, is labelled vegan and gluten-free but contains soya.
Start with the claim that matches your dietary requirement, then check the exact flavour’s ingredients and precautionary wording. In Coeliac UK’s 2025 Shopping Habits survey, 3,785 members responded; the figures below describe those respondents’ views, not crisp shoppers generally.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten-free assurance | Look for a gluten-free statement on the exact product and current packet. The Food Standards Agency defines gluten-free as no more than 20 mg/kg in food as sold to the final consumer; check whether any accreditation you value is displayed. | I want a clear gluten-free claim rather than judging by the base ingredient. Among respondents to Coeliac UK’s 2025 Shopping Habits survey, 74.7% trusted the Crossed Grain Trademark more than a gluten-free statement, and 76.4% wanted all products labelled gluten-free to display it. |
| Other allergens | Read the highlighted ingredients and any “may contain” or factory statement for the exact flavour. Check each allergen you need to avoid; a gluten-free claim addresses gluten, not milk or soya. | Milk, soya or another allergen may determine my choice even when a crisp is labelled gluten-free. I need to assess both recipe ingredients and precautionary wording for the packet I’m buying. |
| Vegan and gluten-free claims | Confirm both claims for the same flavour, then inspect its ingredient list. KETTLE labels Thai Sweet Chilli vegan and gluten-free, but lists soya in its dried tamari sauce. | I’m looking for a vegan afternoon snack that also meets my gluten requirement; vegan wording alone does not answer my other allergen questions. |
| School-provided food | For food provided to pupils in state-funded schools in England, check the applicable School Food Standards and the school or caterer’s current arrangements. The Department for Education says updated standards are proposed from September 2027, subject to Parliamentary approval. | If the snack is being provided at school, I need to check the rules for that setting separately from a personal afternoon-snack purchase. |
A short-sounding flavour name does not establish what may be present through cross-contact. Walkers says its Ready Salted crisps are made in a factory that also handles milk, wheat, gluten, barley, soya, celery and mustard; McCoy’s Salted carries a “may contain” statement for milk, soya, gluten and mustard.
Check the current packet’s claims, ingredients and precautionary statement rather than choosing from the flavour name alone.
Gluten-free and milk-free are different requirements. Seabrook describes Cream Cheese & Chive as gluten-free, but its ingredients include whey powder (milk); KETTLE Sour Cream & Sweet Onion is gluten-free and lists milk ingredients.
Check milk in the ingredients and any precautionary wording for the exact flavour, even when gluten-free is stated prominently.
REAL says its crisp range is gluten-free, but Ham & Colman’s Mustard contains lactose (milk). Likewise, KETTLE Thai Sweet Chilli is labelled vegan and gluten-free while containing soya.
Use a range claim to narrow your options, then confirm the current label on the flavour and pack you choose.
The Department for Education says School Food Standards are legal requirements for food and drink provided to pupils in state-funded schools in England. That scope does not establish a UK-wide rule for every personal crisp purchase.
For a school-provided snack, check the applicable standards and the school or caterer’s current arrangements; for a personal snack, check the product against your dietary requirements.
These brand statements and product examples can help narrow a search, but suitability still depends on the exact flavour and current packet.
Seabrook says its crisps and snacks are gluten-free and Coeliac UK accredited.
REAL says its crisp range is gluten-free and vegetarian.
KETTLE gives dietary and ingredient information for individual flavours.
The listed recipes for Tyrrells Naked (no salt) and Lightly Sea Salted contain potatoes and sunflower oil, with sea salt added to the latter.
Check Walkers by flavour rather than assuming Ready Salted meets a particular free-from requirement.
McCoy’s product information needs checking flavour by flavour for ingredients and precautionary wording.
These Joybuy options include cassava, potato, taro and okra snacks for an afternoon break. Check each current packet against the free-from claims and allergens that matter to you; the base ingredient or flavour name alone cannot establish suitability.

A cassava-based chilli option if you want a change from potato crisps. The 250g pack may cover more than one afternoon snack; check its current dietary claims, ingredients and allergen wording against your requirements.

The product name identifies a vegan-labelled, flavoured potato crisp in a 150g pack. If you also need to avoid gluten or another allergen, check the exact packet’s claims, flavouring ingredients and precautionary statement.

A 50g taro-chip pack for someone considering a smaller afternoon snack. Do not infer gluten-free or vegan suitability from the taro base or sea-salt flavour; check the current packet for the claims and allergen information you need.

An okra-based alternative to potato crisps. If avoiding gluten, check the source of any malt syrup on the exact packet and look for the dietary statement you require; an okra base does not settle that question.
No. The Food Standards Agency defines gluten-free as no more than 20 mg/kg of gluten in food as sold to the final consumer. That definition does not establish the absence of milk, soya or other allergens; check the exact flavour’s ingredients and allergy advice.
It is precautionary allergen wording about possible unintended presence, rather than a declaration that the allergen was used as an ingredient. The Food Standards Agency gives “may contain” and factory statements as examples; check which allergens the wording names on your packet.
No. Walkers Ready Salted says its factory also handles milk, wheat, gluten and other allergens; McCoy’s Salted says it may contain milk, soya, gluten and mustard. Check the particular product’s claims, ingredients and precautionary wording instead of relying on its flavour.
No. A vegan label does not answer every allergen question: KETTLE Thai Sweet Chilli is labelled vegan and gluten-free, but its ingredients include soya. Check the ingredients and precautionary statement for the allergen you need to avoid.
Not for every personal snack purchase. The Department for Education says School Food Standards are legal requirements for food and drink provided to pupils in state-funded schools in England under the Requirements for School Food Regulations 2014. For a school-provided snack, check the applicable standards and the school or caterer’s current arrangements; updated standards are proposed from September 2027, subject to Parliamentary approval.
