Choose the exact pack by your essential requirement first: look for an explicit gluten-free or vegan statement where needed, and check ingredients and allergen wording separately if you need to avoid milk. For a night-shift break, compare salt on the same basis and consider how much of the pack you expect to eat; a plain or no-salt flavour is not automatically suitable for every allergy.
Check the exact flavour and pack for the claim you need. KETTLE Chips, Pipers and Seabrook each identify particular plain crisps as gluten-free and suitable for vegans, but those statements should not be assumed to cover every flavour.
Read salt per 100 g to compare products, then check the labelled serving and pack size. Tyrrells lists Naked (no salt) as a 150 g bag containing five 30 g servings, which makes the amount eaten during a break worth considering.
Check ingredients and precautionary wording on the chosen pack, even if the flavour sounds plain. Tyrrells says Naked (no salt) may contain milk, while Walkers lists several possible allergens for Lightly Salted.
Start with any dietary requirement that the pack must meet. Then compare nutrition values and pack sizes using the same measurement basis.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten and allergens | Look for an explicit gluten-free statement if required. Read the exact flavour’s ingredients and any “may contain” wording separately; a short ingredient list does not settle a milk-allergy question. | I need the pack, not just its plain-sounding flavour, to meet my gluten or allergen requirements. |
| Vegan suitability | Check the chosen flavour’s vegan statement and ingredients. A gluten-free range can include flavours made with milk: Joybuy’s Seabrook variety-box listing identifies lactose and cheese powder in its Cheese & Onion crisps. | If I want vegan crisps, a gluten-free claim alone does not answer that question. |
| Salt | Compare salt per 100 g before comparing differently sized bags. KETTLE Chips lists 0.7 g per 100 g for Lightly Salted, Pipers 0.94 g for Anglesey Sea Salt and Seabrook 1.3 g for Sea Salted, according to their respective product information. | I want to compare the plain options on the same basis, then check the amount in the portion I might eat. |
| Pack size | Read both the serving size and servings per pack. Tyrrells lists Naked (no salt) as 150 g with five servings; Seabrook lists Sea Salted as a 31.8 g bag. | A bag I can carry to work may still contain more than one labelled serving. |
Tyrrells lists only potatoes and sunflower oil as ingredients for Naked (no salt), but also says it may contain milk. Walkers Lightly Salted carries precautionary wording for milk, wheat, gluten and other allergens.
For an allergy or a gluten-free requirement, check the current pack’s claims, ingredients and precautionary wording rather than choosing by flavour name.
A value per serving and a value per bag describe different amounts when the bag contains several servings. Tyrrells lists five 30 g servings in its 150 g Naked (no salt) bag.
Use salt per 100 g for a like-for-like product comparison, then check the labelled serving against the amount you expect to eat.
Seabrook describes its crisps and snacks as gluten-free, but the Cheese & Onion flavour in a Joybuy variety-box listing contains lactose and cheese powder.
Check each flavour in a multipack for milk ingredients and vegan suitability, even when the range carries a gluten-free statement.
Department for Education school-food guidance concerns food and drink provided to pupils in state-funded schools in England. That is a different setting from an adult buying crisps for a night shift.
For a personal snack, focus on the exact pack’s allergen information, nutrition values and portion size rather than treating school-catering rules as a general retail ban.
Its Lightly Salted crisp offers a reduced-salt comparison within the Walkers range.
Naked (no salt) is a plain option made with potatoes and sunflower oil.
KETTLE identifies its Lightly Salted crisps as gluten-free and suitable for vegans and vegetarians.
Seabrook states that its gluten-free crisps and snacks are Coeliac UK accredited.
Pipers identifies Anglesey Sea Salt as gluten-free and suitable for vegans and vegetarians.
REAL states that its crisp range is gluten-free and vegetarian, with selected vegan recipes.
These options include plain salted crisps and more strongly flavoured packs for a night-shift break. Where a dietary claim is essential, check that claim and the allergen wording on the exact pack before choosing.

The manufacturer lists 0.7 g salt per 100 g. Check the current pack’s allergen wording if you need to avoid milk or another named allergen.

The pickled-plum flavour offers a different choice for a work break, but its flavour name does not establish free-from suitability.
Check the 100 g pack’s ingredients, dietary claims, allergen wording and salt value against your requirements.

Choose the truffle-and-rosemary flavour only if it suits your taste and the exact pack meets any dietary requirements you have.
For this 150 g pack, check the flavour-specific ingredients and allergen wording, as well as salt per 100 g and per serving.

This named flavour is an alternative to plain crisps for a night-shift break; confirm any vegan or gluten-free requirement from the exact pack rather than its flavour name alone.
The pack is 150 g. Check its ingredients, allergen statements, serving information and salt value before deciding how much to take to work.
No: a plain flavour name is not a gluten-free claim. KETTLE Chips identifies Lightly Salted as gluten-free, as Pipers does Anglesey Sea Salt and Seabrook does Sea Salted; check that the current pack is the same product.
No. Gluten-free and milk-allergen information answer different questions: the Cheese & Onion crisps in a Joybuy Seabrook variety-box listing contain lactose and cheese powder. Check each flavour’s ingredients and precautionary wording.
Compare salt per 100 g for a like-for-like product comparison, then check the serving and pack size. Tyrrells lists 0.02 g per 30 g serving for Naked (no salt), but its 150 g bag contains five servings; Walkers lists 0.17 g per 25 g pack for Lightly Salted.
Read the ingredients and any precautionary allergen statement for the exact flavour. Food Standards Scotland says food businesses must tell consumers when food contains any of the 14 allergens that must be declared under UK law; a “may contain” statement is a separate warning worth checking for your particular allergen.
No general restriction on an adult’s personal night-shift purchase follows from those rules. Department for Education guidance applies to food and drink provided to pupils in state-funded schools in England; it describes updated standards planned for September 2027 as subject to Parliamentary approval.
