Who is this for?

Coeliac shoppers packing a snack

An individual bag is convenient for lunch or a journey, but its potato base alone does not establish gluten-free suitability. Coeliac UK advises checking seasoning and precautionary allergen information.

Shoppers looking for flavoured crisps

Seabrook describes its gluten-free range as Coeliac UK accredited and lists flavoured options. Check the specific flavour’s current pack rather than carrying a claim across the whole crisp aisle.

Shoppers buying individual bags by the case

REAL lists cases of 24 × 35g bags, while KETTLE lists gluten-free single-bag cases of 18 × 40g. Check the flavour and individual pack size before choosing a case.

What should you check?

Check the exact bag’s gluten-free and allergen information first, then compare its portion size and nutrition panel with how you plan to use it.

Priority What to check Your needs
Gluten-free labelling Look for an explicit gluten-free claim on the exact pack. Read its ingredients and any “may contain gluten” statement; Coeliac UK warns that seasoning and manufacturing can affect suitability. I need a crisp bag I can assess from its own current label, not from the fact that it contains potatoes or carries a familiar brand name.
Bag size Confirm the weight of each bag, not just the case size. Seabrook lists 25g Canadian Ham and 31.8g Beefy bags; REAL lists 35g bags and KETTLE lists 40g single bags. For a packed lunch, I want an individual bag rather than finding that the product I chose is a sharing bag.
Flavour Check the ingredients and allergen information for the chosen flavour. Repeat the check when buying a different variety or a pack with updated labelling. I would like a flavoured option without assuming another flavour from the same brand has identical ingredients or warnings.
Per-bag nutrition Compare figures for the bag you intend to eat. Seabrook lists 126 kcal and 0.4g salt per 25g Canadian Ham bag, and 160 kcal and 0.4g salt per 31.8g Beefy bag. If I buy these regularly, per-bag figures help me compare the actual portions rather than relying only on values per 100g.

Common buying mistakes

  • Assuming potato crisps are automatically gluten-free

    Coeliac UK notes that seasoning and the manufacturing environment can affect whether a potato crisp is suitable for a gluten-free diet.

    Choose a product explicitly labelled gluten-free and inspect the ingredients and precautionary wording on the flavour you are buying.

  • Applying one flavour’s label to another

    Ingredients and warnings can differ between varieties. McCoy’s Salted, for example, carries a “may contain gluten” statement in the brand’s product information.

    Check each flavour and pack separately, including products from brands you have bought before.

  • Mistaking a sharing bag for a grab bag

    Tesco and Waitrose list Tyrrells Naked-No Salt as a gluten-free 150g sharing bag. That does not make it an individual 25g–40g portion.

    Check the weight of each bag, particularly when a listing describes a case or multipack.

  • Relying on an old online description

    Tesco and Waitrose caution that recipes and allergen information can change, so a listing may not reflect the pack in hand.

    Use the listing to identify an option, then read the unopened pack’s current gluten-free, ingredient and precautionary information.

Brand references for coeliac shopping

Seabrook

Seabrook says its gluten-free crisp and snack range is Coeliac UK accredited.

  • Its Canadian Ham product page lists a gluten-free 25g bag; Beefy is listed as a gluten-free 31.8g bag.
  • Bag size, ingredients and nutrition are flavour-specific, so check the variety you choose.

REAL Hand Cooked Crisps

REAL says its range is gluten-free and lists individual 35g bags in cases.

  • Its shop lists several 24 × 35g case options.
  • REAL directs shoppers to each flavour pack for allergen details; check the current bag.

KETTLE Chips

KETTLE has a gluten-free collection of 18 × 40g single-bag cases.

  • The collection includes Lightly Salted; KETTLE separately describes its Lightly Salted product as gluten-free.
  • The separate product page concerns a sharer case. Check the exact 40g bag’s label and current availability.

Tyrrells

Tesco and Waitrose describe Tyrrells Naked-No Salt 150g as gluten-free, but that listing concerns a sharing bag.

  • The listed Naked-No Salt product contains potatoes and sunflower oil.
  • The listing does not establish the status of other Tyrrells flavours or grab-bag sizes; read each pack.

Walkers

Walkers products need checking by exact flavour and pack when shopping for a gluten-free crisp.

  • Walkers publishes ingredient and factory-handling information for Ready Salted.
  • That product information states the factory also handles wheat, gluten and barley; do not infer a gluten-free claim from the flavour name.

McCoy’s

McCoy’s Salted is not a choice for the gluten-free-labelled route described here.

  • Its product information states the ingredients and precautionary allergens for this flavour.
  • The Salted flavour says it may contain gluten. Assess any other McCoy’s product from its own current pack.

Joybuy product options

This Joybuy option is an 80g cassava-chip bag, rather than one of the smaller potato-crisp portions discussed above. Check its current pack against your coeliac-shopping requirements.

Tropical Sun Lightly Salted Cassava Chips 80g

Tropical Sun Lightly Salted Cassava Chips 80g

For a portable snack, note that this 80g bag is larger than the 25g–40g individual portions above and contains cassava chips rather than potato crisps. Before choosing it for coeliac shopping, check the current pack for an explicit gluten-free claim, ingredients and any precautionary gluten statement.

Questions about crisp labels

Are all potato crisps suitable for coeliac shopping?

No. Coeliac UK explains that seasoning and manufacturing can affect suitability even though potatoes are naturally gluten-free. Look for an explicit gluten-free claim and read the exact pack’s allergen information.

Can I rely on a simple-looking ingredient list instead of a gluten-free claim?

Do not rely on the potato base or a simple flavour name alone. Coeliac UK advises considering seasoning and possible cross-contamination, so check the current pack’s gluten-free claim and precautionary wording.

What if the pack says “may contain gluten”?

Do not use it for the gluten-free-labelled shopping route described here. Coeliac UK says that wording can indicate a manufacturing cross-contamination risk.

Should I recheck a crisp bag I buy regularly?

Yes. Tesco and Waitrose caution that recipes and allergen information can change. Read the current physical pack, even when you recognise the product.

Does one suitable flavour mean every flavour from that brand is suitable?

No. Check the exact flavour and pack. Tesco and Waitrose describe Tyrrells Naked-No Salt 150g as gluten-free, while McCoy’s says its Salted flavour may contain gluten; neither statement establishes the status of other products from those brands.
