Who is choosing the crisps?

Car boot sale sellers serving mixed dietary needs

Sealed packs let visitors inspect the ingredients and allergen information for the flavour they choose. If the selling activity is a food business, the Food Standards Agency says allergen information must be provided for food supplied.

Buyers looking for gluten-free crisps

A potato-based crisp is not automatically suitable for someone avoiding gluten. Coeliac UK notes that seasonings can contain wheat flour or barley malt extract and that packs may carry precautionary gluten wording.

Vegan buyers checking other allergens

A vegan claim helps identify an option without animal-derived ingredients, but it does not answer whether the crisp contains an allergen such as soya. Check the exact flavour’s ingredient and allergen statement.

What should you check before buying?

Start with the requirement the crisp needs to meet, then check the exact pack rather than relying on a flavour name or a single front-of-pack claim.

PriorityWhat to checkYour needs
Gluten-free identification Look for a gluten-free claim on the exact product. Read the ingredients and any precautionary gluten statement; Coeliac UK notes that crisp seasonings can contain wheat flour or barley malt extract. I need to identify a gluten-free option without judging it by the potato base alone. In Coeliac UK’s 2025 Shopping Habits survey, 74.7% of its 3,785 member respondents said they trusted the Crossed Grain Trademark more than a gluten-free statement; that measures trust, not crisp-buying demand.
Other allergens Check the full ingredients and allergen wording for the specific flavour. KETTLE Chips lists tamari soy sauce in Thai Sweet Chilli, despite labelling it gluten-free and vegan. Someone avoiding soya needs more information than a gluten-free or vegan claim provides.
Vegan suitability Look for an explicit vegan statement on the exact flavour. Seabrook labels both Beefy and Sea Salt & Vinegar as suitable for vegans; a flavour name alone cannot settle the question. I want visitors seeking a vegan crisp to be able to recognise the appropriate pack without guessing from its name.
Information at the table Keep each flavour in its labelled pack, or retain matching product information where the label can be checked. For food businesses, the Food Standards Agency says allergen information is required for both prepacked and non-prepacked food. If I offer several flavours, visitors need to see which ingredients and allergen statements belong to the crisp they are considering.

Common selection mistakes

  • Assuming potatoes or a plain flavour mean gluten-free

    Coeliac UK notes that flavourings may contain wheat flour or barley malt extract, while manufacturing cross-contact can lead to a “may contain gluten” statement.

    When gluten avoidance is required, choose an exact product labelled gluten-free and check its current pack before offering it.

  • Reading vegan or gluten-free as free from every allergen

    KETTLE Chips labels Thai Sweet Chilli gluten-free and vegan, but lists tamari soy sauce among its ingredients.

    Find out which ingredient must be avoided, then read the complete statement for that flavour.

  • Overlooking precautionary wording on a short ingredient list

    Tyrrells Naked lists potatoes and sunflower oil but also says “may contain milk”. Walkers Ready Salted states that it is made in a factory that handles several named allergens.

    Assess precautionary and factory statements alongside the ingredients when selecting for an allergy-related requirement.

  • Separating crisps from their labels

    Without the matching pack, visitors cannot readily check the manufacturer’s ingredient and allergen information for each flavour.

    Offer sealed, labelled packs where practical and keep the relevant information available if crisps are served differently.

Brand and flavour references

Dietary claims and allergen statements differ by flavour, so these examples are starting points for checking the exact pack, not claims about every product from a brand.

Pipers

Pipers labels Anglesey Sea Salt gluten-free, vegetarian and vegan.

  • For this flavour, Pipers lists potatoes, sunflower oil and Anglesey Sea Salt PDO.
  • Check other flavours separately; these claims do not establish their milk or other allergen status.

Seabrook

Seabrook says its crisps and snacks are gluten-free and Coeliac UK accredited.

  • Seabrook labels Beefy and Sea Salt & Vinegar gluten-free and suitable for vegetarians and vegans.
  • A gluten-free range claim does not establish whether a particular flavour meets another allergen requirement.

REAL Hand Cooked Crisps

REAL describes its crisp range as gluten-free and vegetarian, with six recipes suitable for vegans.

  • The brand provides flavour-specific information to consult when choosing a pack.
  • Its statement about six vegan recipes does not make every flavour vegan.

KETTLE Chips

KETTLE Chips labels Thai Sweet Chilli gluten-free and suitable for vegans and vegetarians.

  • The product offers a labelled vegan and gluten-free flavour to consider.
  • Its ingredients include tamari soy sauce, so it is not a choice for someone avoiding soya.

Walkers

Walkers Ready Salted needs a product-specific check when visitors have allergen requirements.

  • Walkers states that Ready Salted is made in a factory that also handles milk, wheat, gluten, barley, soya, celery and mustard.

Tyrrells

Tyrrells Naked is a no-added-salt flavour, but its short ingredient list does not settle a milk-related choice.

  • Tyrrells lists potatoes and sunflower oil as its ingredients.
  • The same product says “may contain milk”; do not presume it meets a milk-free requirement.

Questions about serving and selling crisps

Are all potato crisps suitable for a gluten-free diet?

No. Coeliac UK notes that seasonings can contain wheat flour or barley malt extract and that packs may carry “may contain gluten” wording. Where gluten avoidance is required, choose an exact product labelled gluten-free and check its current pack.

Does vegan mean free from other allergens?

No. KETTLE Chips labels Thai Sweet Chilli vegan and gluten-free, yet lists tamari soy sauce in its ingredients. Check the exact crisp against the allergen the visitor needs to avoid.

Should I put crisps into bowls at a car boot sale?

Sealed original packs make it easier for visitors to check the matching ingredients and allergen statement. If the activity is a food business and crisps are served outside their packs, the Food Standards Agency’s guidance still requires allergen information for non-prepacked food.

Do I need to register before selling crisps?

If the activity is a new food business, the Food Standards Agency registration service says it must register with its local authority at least 28 days before trading. Whether a particular occasional car boot sale counts as a food business depends on the activity; ask the relevant local authority rather than assuming registration is, or is not, required.
