Who is each format for?

For a large family shop, the useful pack size depends on whether crisps are going into separate lunches, being served at home or bought for someone with specific dietary requirements.

Households planning packed lunches

Individual packets make it easier to set aside snacks for school, work or travel. Compare their total weight and unit price with sharing bags rather than judging value by the number of packets.

Families sharing crisps at home

A larger bag or tub allows you to serve portions from one pack. Consider how soon the household will finish it after opening, as well as its unit price.

Households checking dietary suitability

Check the exact flavour and pack before buying several at once. Ingredients, dietary claims and precautionary allergen statements can differ between products from the same brand.

What should you compare?

Start with a like-for-like weight comparison, then decide whether the portions and flavours will work for your household. A case is worth considering only if you can use and store its contents.

Priority What to check Your needs
Comparable value Compare the displayed £/100g or £/kg using the same unit. Check which loyalty or multibuy conditions apply to each price. The Competition and Markets Authority warns that assumptions about the cheapest grocery option per unit are not always right. Will the larger bag or multipack give me a lower unit price for the crisps I will actually use?
Pack format For multipacks and cases, check packet count and weight per packet; for sharing packs, check total weight. Consider storage and how quickly an opened pack or a case of one flavour will be used. Separate packets suit lunches I need to plan ahead. For snacks served together at home, I can portion a sharing bag instead.
Ingredients and allergens Read the ingredients and any precautionary allergen statement for every chosen flavour. Check dietary labels on the exact product, not just the brand name; GOV.UK identifies crisp packets as prepacked food whose listed allergens appear in the ingredients information. If someone in my household has an ingredient or dietary restriction, I need to check each flavour before buying it in quantity.
Nutrition per portion Read both per-100g and per-serving figures, noting the labelled serving weight. For a sharing bag, compare those figures with the portion you intend to serve rather than assuming it matches the label’s serving. When I serve crisps from a larger bag, I want to compare salt information for the amount put out, not just for 100g.

Common buying mistakes

  • Assuming the largest pack costs less per gram

    A lower shelf price and a lower unit price are different things. The Competition and Markets Authority says familiar assumptions about grocery unit prices are not always right.

    Compare the displayed price per 100g or per kg for the exact packs, including any conditions attached to a promotion.

  • Buying a case before settling on a flavour

    A case commits the household to many packets of the chosen flavour. If preferences change, some may go unused.

    Try a smaller pack when preferences are uncertain. For a repeat purchase, check the case’s total weight, best-before information, storage needs and delivered unit price.

    A delivery charge can affect the unit-price comparison, and unused packets can become waste.

  • Relying on a brand-wide dietary description

    Ingredients and precautionary allergen statements can vary by flavour. Walkers Ready Salted, Tyrrells Lightly Sea Salted and McCoy’s Salted have different product-specific statements on their cited brand pages.

    Read the current label for the exact pack and flavour, including any “may contain” wording relevant to the household.

  • Comparing nutrition without considering portion size

    A labelled serving in an individual packet may differ from the amount served from a sharing bag, so the per-serving figures may not describe the portions being compared.

    Check the labelled serving weight alongside the per-100g figures, then compare them with the portions you plan to put out.

Brand and product-range references

These examples show formats and label details worth checking; a characteristic of one flavour does not necessarily apply across a brand’s range.

Walkers

Its range includes individual multipacks as well as classic potato-crisp flavours. A Ready Salted 12 x 25g format illustrates the separately portioned option.

  • The Walkers Ready Salted product page lists its ingredients and states vegetarian suitability.
  • That flavour’s page also notes factory handling of several allergens; check the particular pack and flavour before buying.

Tyrrells

Tyrrells lists Lightly Sea Salted in 40g, 150g and 600g formats, giving households different pack sizes to compare.

  • The cited flavour lists potatoes, sunflower oil and sea salt as ingredients.
  • It carries a “May contain Milk” statement. Its larger formats should still be compared by unit price.

KETTLE Chips

The KETTLE Lightly Salted Sharers Box is a sharing-format reference for households comparing larger purchases.

  • KETTLE labels this specific Lightly Salted product gluten-free and suitable for vegans and vegetarians.
  • Check other flavours and boxes individually rather than extending those labels to the entire range.

Seabrook

Seabrook’s cited Sea Salted crinkle-cut crisps come in a 31.8g pack.

  • Seabrook labels this flavour gluten-free and suitable for vegetarians and vegans.
  • Its product page lists 0.4g salt per 31.8g bag and 1.3g per 100g; use the label of any other flavour for that flavour’s figures.

McCoy’s

McCoy’s lists a Big Sharing range alongside its standard ridged crisps.

  • The separate sharing range provides another format to consider for crisps served at home.
  • The cited Salted flavour may contain milk, soya, gluten and mustard; check each flavour’s own label.

REAL Hand Cooked Crisps

REAL’s direct shop lists 24 x 35g cases, a format for households planning repeated use of individual packets.

  • REAL states that its range is vegetarian and gluten-free.
  • Check the chosen flavour’s allergen information, and compare a case’s delivered unit price with other formats before ordering.

Questions about buying crisps in quantity

How do I compare crisp value for a large family shop?

Compare the displayed price per 100g or per kg for the exact packs, accounting for any loyalty or multibuy conditions. The Competition and Markets Authority cautions that assumptions about which groceries cost less per unit are not always right, so do not decide from shelf price or pack size alone.

Where should I check allergens on a packet of crisps?

Read the ingredients list and any precautionary allergen statement on the exact flavour and pack. GOV.UK identifies packets of crisps as prepacked food and says that regulated allergens present in the product are clearly labelled in its ingredients list.

Can I assume every flavour from a brand has the same dietary labels?

No. Check the exact product and flavour: KETTLE labels its cited Lightly Salted product gluten-free and suitable for vegans and vegetarians, while Seabrook makes those statements for its cited Sea Salted product. Neither example establishes the ingredients or labels of another flavour.

What should I check before buying a large sharing pack?

Check its unit price, best-before information and storage instructions, then consider how soon you will use it after opening. Tyrrells advises storing its cited Lightly Sea Salted product in a cool, dry place; portioning and resealing an opened bag can help you manage what remains.
