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.
Compare the price per 100g or per kg for the exact packs you might buy, then choose a format that fits how your household serves crisps: individual packets for planned snacks, or sharing packs when you can portion and use them promptly. The Competition and Markets Authority cautions that familiar assumptions about which groceries cost less per unit are not always right. Before stocking up, check each flavour’s ingredients, allergen information and nutrition label.
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.
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.
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.
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.
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. |
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.
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.
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.
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.
These examples show formats and label details worth checking; a characteristic of one flavour does not necessarily apply across a brand’s range.
Its range includes individual multipacks as well as classic potato-crisp flavours. A Ready Salted 12 x 25g format illustrates the separately portioned option.
Tyrrells lists Lightly Sea Salted in 40g, 150g and 600g formats, giving households different pack sizes to compare.
The KETTLE Lightly Salted Sharers Box is a sharing-format reference for households comparing larger purchases.
Seabrook’s cited Sea Salted crinkle-cut crisps come in a 31.8g pack.
McCoy’s lists a Big Sharing range alongside its standard ridged crisps.
REAL’s direct shop lists 24 x 35g cases, a format for households planning repeated use of individual packets.
These Joybuy options cover individual multipacks and 150g sharing bags for the family-shop decision. Compare their current unit prices and check each chosen flavour’s label before buying.

Six individual 24g packets are an option for setting aside separate snacks. Compare the price per 100g with sharing packs, and check the pack’s ingredients and allergen statement for your household.

This 20-packet variety format suits a household planning a larger supply of individual snacks. Check the flavours in the pack against household preferences and read each flavour’s allergen information; compare its unit price with other formats.

This 150g bag is a sharing option when portions will be served at home. Tyrrells lists potatoes, sunflower oil and sea salt for this flavour and states “May contain Milk”. Compare its unit price with individually packed alternatives.

This 150g sharing bag offers a different flavour for crisps served together at home. Check its own ingredients and allergen label rather than relying on information for Tyrrells Lightly Sea Salted, and compare the two bags by unit price.

Six individual 22g packets provide a format for planned lunches or separate snacks. Compare the price per 100g with other multipacks and sharing bags, and check the flavour’s ingredients and allergen information.
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.
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.
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.
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.
