For crisps alongside an existing desk lunch, start with an individually packed 25–35g option; choose a 45–50g bag if you want a larger packet. Pack information from Walkers UK, Tesco Groceries and ASDA Groceries shows why it matters to compare nutrition for the amount you will eat, then check the exact flavour’s ingredients, allergens and dietary statements.
If the packet is a side rather than the main snack, its net weight matters. Reviewed packs range from Walkers UK’s 25g Ready Salted packet to the 35g REAL listing at Tesco Groceries and the 45g McCoy’s grab bag at ASDA Groceries.
Look at the salt and energy for the amount you expect to eat. A bag labelled as two servings needs a different calculation from one labelled as a single serving. For context, the NHS advises adults to have no more than 6g of salt a day.
Choose by exact flavour and current packet, not by brand alone. The reviewed labels include specific vegan and gluten-free statements as well as ingredients and precautionary allergen information that differ between products.
Decide how much of the bag you intend to eat, then compare its nutrition and ingredients on that basis. Leave texture and flavour until after any dietary requirements have been checked.
| Priority | What to check | Your needs |
|---|---|---|
| Packet and serving size | Check net weight, servings per bag and whether the nutrition figures cover a serving or the whole bag. ASDA Groceries lists the reviewed McCoy’s 45g bag as one serving, but gives figures for the reviewed Seabrook 50g bag per half-bag. | I want a packet to go alongside lunch, not a larger bag that I might mistake for the same portion. |
| Nutrition for the amount eaten | Compare energy, fat and salt for the whole packet or the portion you plan to eat. Walkers UK lists 0.34g salt per 25g Ready Salted pack; ASDA Groceries lists 0.95g per 45g McCoy’s Salt & Malt Vinegar pack. These are different flavours and pack sizes. | Salt matters to me, so I will use the exact flavour’s pack figures rather than judge it by its name. The NHS advises adults to have no more than 6g of salt a day. |
| Ingredients and dietary labels | Read the exact packet’s ingredient list, highlighted allergens, precautionary statements and any vegan or gluten-free wording. Tesco Groceries labels the reviewed Seabrook Sea Salted 6 × 25g pack vegan and gluten-free; that statement does not cover every flavour. | I need to know whether this particular flavour meets my dietary requirements before I eat it. |
| Flavour and format | Once size and ingredients work for you, compare the stated cut, base ingredient and seasoning. Seabrook describes its potato crisps as crinkle-cut; Tyrrells also offers a lentil-crisp range. | For a quick lunch, I would rather pick a texture and flavour deliberately than assume every crisp packet is much the same. |
ASDA Groceries presents nutrition for the reviewed Seabrook 50g bag per 25g half-bag, while its reviewed McCoy’s 45g grab bag states one serving per pack. Reading only the serving column can understate what you eat if you finish a two-serving bag.
Check the net weight and serving count, then work out the figures for the amount you intend to eat.
Pack values differ: Walkers UK lists 0.34g salt for its 25g Ready Salted packet, while ASDA Groceries lists 0.95g for a 45g McCoy’s Salt & Malt Vinegar packet. The comparison involves different flavours and sizes, not a brand-wide rule.
Compare salt for the exact packet you plan to eat.
Ingredients and allergen statements are product-specific. For example, the reviewed McCoy’s Salt & Malt Vinegar listing includes barley, while a reviewed Seabrook Sea Salted pack is labelled vegan and gluten-free.
Read the current packet for the precise flavour and size, including any may-contain statement.
Tyrrells describes its Naked no-salt crisps as a 150g pack with five suggested 30g servings. Its pack format does not separate those servings for you.
If you choose that recipe for lunch, put the amount you want into a separate container beforehand.
These examples show why the individual flavour and pack format matter; a characteristic of one reviewed product does not apply to an entire range.
Walkers UK presents nutrition per 25g pack for its Ready Salted potato crisps.
Tyrrells offers hand-cooked potato crisps, a Naked no-salt option and lentil crisps.
KETTLE Chips describes its reviewed Lightly Salted potato crisps as suitable for vegans and vegetarians and gluten-free.
Seabrook’s reviewed crinkle-cut products include individually packed Sea Salted crisps and a larger Beefy bag.
The reviewed McCoy’s Salt & Malt Vinegar product is a 45g grab bag.
REAL offers selected flavours in 35g packs, including the reviewed salt-and-vinegar listing.
These McCoy’s multipacks offer separate bags that can be taken with a desk lunch. Check the weight and label of each flavour when deciding whether a bag suits the portion you want.

The multipack format lets you take one bag with lunch. Check that bag’s weight and nutrition panel for your intended portion, and read the current ingredients and allergen statements if milk or other allergens matter to you.

This is another multipack choice for taking one bag to a desk lunch. Use the individual bag’s nutrition figures for comparison, and check its current milk and precautionary allergen information before choosing it for a dietary requirement.

Its six 25g bags provide an individually packed option alongside lunch. Check the current packet’s flavour, salt figure and barley or precautionary allergen statements before selecting it.

A variety multipack offers a choice of bags for different lunches. Compare the nutrition for the particular flavour you take, and check each packet’s ingredients because dietary suitability can differ across a variety pack.

With six separate 25g bags, this multipack lets you take one packet to work. The flavours may have different ingredients, so read the individual packet’s nutrition and allergen information rather than relying on the multipack name.
No. ASDA Groceries lists the reviewed McCoy’s 45g Salt & Malt Vinegar bag as one serving but gives nutrition for the reviewed Seabrook Beefy 50g bag per 25g half-bag. Check both the bag weight and serving count before comparing whole packets.
Compare salt for the whole packet or the amount you expect to eat, using the exact flavour’s label. Walkers UK lists 0.16g per 25g Pickled Onion pack, while ASDA Groceries lists 0.95g per 45g McCoy’s Salt & Malt Vinegar pack. For context, the NHS advises adults to have no more than 6g of salt a day.
No. Look for a statement covering the exact product and read its ingredients and allergen information. Tesco Groceries labels the reviewed Seabrook Sea Salted 6 × 25g multipack vegan and gluten-free, but that does not establish the status of other flavours or brands.
Start with the net weight, serving count, nutrition panel and ingredients, including highlighted allergens. UK Government food-labelling guidance also identifies date information among the particulars required on prepacked-food labels. For an allergy or dietary requirement, check the current physical packet rather than relying solely on a retailer listing.
Recycle Now says crisp packets are not currently recyclable in home recycling collections. Check the packet’s instructions and local collection options before disposing of it.
