Shoppers choosing one crisp portion
If the bag is for one snack or lunchbox, its weight and whole-bag nutrition help you compare it with other individual packs.
Who is this for?
Shoppers checking dietary suitability
Check claims and allergen wording for the exact flavour and pack, particularly if your grocery order might include a substitute.
Shoppers managing substitutions
If flavour, portion size or ingredients matter, decide in advance whether a different crisp product would be acceptable.
What should you check?
Start with the portion you intend to eat, then check the exact recipe and how your retailer handles substitutions.
| Priority | What to check | Your needs |
|---|---|---|
| Whole-bag portion | Check the bag weight, whether it is listed as one serving, and the energy, fat and salt for that bag. Walkers UK lists 96 kcal and 2.8g fat for its 22g Oven Baked Sea Salt pack; Tyrrells lists 208 kcal and 11.7g fat for its 40g Lightly Sea Salted pack. | I’m choosing one snack, so I want to compare what is in the whole pack, not assume a 22g bag and a 40g bag are equivalent portions. |
| Ingredients and allergens | Read the ingredients, allergen statement and any precautionary wording for the exact flavour. Check a substitute separately rather than relying on the original item’s details. | If an ingredient or dietary claim determines my choice, I need the delivered pack to meet that requirement too. |
| Flavour and format | Check whether the product is a baked potato-based snack, sliced-potato crisp or tub, and whether the seasoning is the flavour you want. Compare pack sizes before choosing a multipack. | A plain sea-salt bag, a strongly flavoured crisp and a potato-based snack in a tub are different choices for my order. |
| Substitutions | Review the retailer’s substitution setting and any picker-note option. Tesco says it may offer an alternative when substitutions are allowed and the requested item is unavailable. | When only the selected flavour, portion or ingredient list will do, I would rather set clear preferences than assume a similar-looking crisp is interchangeable. |
Common buying mistakes
-
Treating every grab bag as the same portion
The individual product examples from Walkers UK, Seabrook Crisps and Tyrrells span 22g to 40g, so a per-100g figure alone does not tell you what is in the bag you plan to eat.
Compare the pack weight and whole-bag nutrition for each option.
-
Accepting a substitute without checking its label
A replacement flavour or recipe can change the ingredients, allergen wording and portion size. Similar crisp names do not establish the same dietary suitability.
If the exact item matters, set your substitution preference or leave a precise picker note where the retailer offers that option. Check the delivered pack before eating.
-
Assuming baked and hand-cooked mean the same recipe
Walkers Oven Baked Sea Salt is described as a potato-flake-and-starch snack, while the Tyrrells Lightly Sea Salted and Seabrook Sea Salted recipes described here use potatoes, oil and salt. The cooking description alone does not establish which pack meets your nutrition or ingredient priorities.
Choose the format you want, then compare the exact product’s ingredients, whole-bag nutrition and allergen wording.
Brand and product references
These examples illustrate different individual-pack recipes and sizes; a brand name alone does not establish the ingredients or suitability of every flavour.
Walkers
The individual-pack examples include Ready Salted, Oven Baked Sea Salt and Lightly Salt & Vinegar.
- Walkers UK lists 2.8g fat per 22g Oven Baked Sea Salt pack and 0.17g salt per 25g Lightly Salt & Vinegar pack.
- Those figures describe different recipes; check the exact flavour’s pack size, ingredients and allergen wording.
Tyrrells
Lightly Sea Salted offers a 40g hand-cooked pack listed by Tyrrells as one serving.
- Tyrrells lists 208 kcal, 11.7g fat and 0.26g salt per 40g pack.
- The product information says it may contain milk. Compare its 40g portion with smaller bags on a whole-pack basis.
KETTLE Chips
KETTLE describes its Lightly Salted product as gluten-free and suitable for vegans and vegetarians.
- The stated dietary claims apply to Lightly Salted, not automatically to other flavours.
- Check the size and format of the particular listing before treating it as an individual grab bag.
Seabrook
Sea Salted is a 31.8g crinkle-cut bag described by Seabrook Crisps as gluten-free and suitable for vegetarians and vegans.
- Seabrook Crisps lists 164 kcal, 9.7g fat and 0.4g salt per 31.8g bag.
- Check its whole-bag figures against the size of any alternative, rather than comparing unequal bags as though they were the same portion.
Pipers
Anglesey Sea Salt is a plain-flavour reference alongside Pipers’ other seasoned crisps.
- Pipers lists potatoes, sunflower oil and Anglesey Sea Salt PDO as its ingredients and labels this product gluten-free and suitable for vegetarians and vegans.
- Confirm the individual pack size and exact flavour when selecting a grocery listing.
REAL Hand Cooked Crisps
REAL lists a 35g Sea Salt bag as well as a larger format and separately flavoured products.
- REAL gives 1.3g salt per 100g for Sea Salt; use the selected bag’s label for a whole-portion comparison.
- Do not carry Sea Salt’s ingredient or dietary details across to another flavour: REAL’s Strong Cheddar & Onion ingredient list includes milk ingredients.
Joybuy product options

Questions about ordering crisps
Should I compare crisps per 100g or per bag?
Compare the whole-bag values first if you expect to eat one bag. Walkers UK lists 96 kcal and 2.8g fat for a 22g Oven Baked Sea Salt pack, while Tyrrells lists 208 kcal and 11.7g fat for a 40g Lightly Sea Salted pack; their different weights matter to that comparison.
Can my online grocery order include a different crisp?
Yes, where substitutions are allowed: Tesco says it may offer an alternative if the requested item is unavailable. Tesco also lets shoppers leave substitution preferences for the picker. If the exact flavour, size or ingredients matter, set those preferences and check any delivered alternative.
What allergen information should I check on delivered crisps?
Check the ingredients, allergen statement and precautionary wording on the exact pack before eating, including any substitute. UK guidance from the Food Standards Agency and Food Standards Scotland describes food businesses’ duties to provide information about regulated allergens; the wording can differ between crisp recipes and flavours.
