For a portioned half-term snack, compare calories, pack weight and salt on the individual bag rather than choosing by a multipack label or a per-100g figure alone. Seabrook lists 81 kcal and 0.39g salt for an 18g bag of Salt & Vinegar Crunchies, while Walkers lists 96 kcal and 0.19g salt for a 22g pack of Oven Baked Sea Salt. The smaller bag has fewer calories but more salt per bag, so neither figure settles the choice on its own.
If you are stocking up for days at home or outings, individual bags make it straightforward to compare the amount in each snack. Check the calories, salt and allergen declaration for the particular flavour you choose.
If you are considering oven-baked crisps or smaller crisp-like snacks alongside conventional crisps, compare the bag weight as well as the calories. An 18g bag and a 22g bag are different portions.
A snack bought for use at home is a different question from food provided by a school. Check which UK nation and school arrangements apply before using a retail food label or promotion rule to make a school-food decision.
Start with the portion you expect to serve, then compare its nutrition information and the exact flavour’s dietary information.
| Priority | What to check | Your needs |
|---|---|---|
| Portion and calories | Read the kcal and weight in grams for one inner bag. Check how many bags the multipack contains; do not substitute a per-100g value for the portion you plan to serve. | I want to know how much one snack contains, whether I am packing it for an outing or keeping it in the cupboard for another day. |
| Salt and fat | Compare salt on the same per-bag basis as calories. Check the stated basis of any lower-fat claim: Walkers describes its Oven Baked Sea Salt crisps as having 50% less fat than regular potato crisps, but that claim does not describe their salt content. | A smaller calorie figure is not my only consideration. I want to see what changes when I choose a different bag size or crisp format. |
| Flavour and allergens | Check the ingredient list, allergen declaration and any may-contain statement on the exact flavour and current pack. Check vegetarian, vegan or gluten-free labelling for that product rather than assuming it applies across a brand. | If a child has ingredients to avoid, I need information for the bag I will actually serve, not another flavour in the range. |
| School context | Establish whether the food is for home, a parent-provided snack or food supplied by a school. For school-provided food, check the relevant nation’s requirements and the school’s arrangements. | I do not want to mistake rules about retail promotions for a decision about what a school can provide. |
Seabrook lists 81 kcal for an 18g bag of Salt & Vinegar Crunchies; Walkers lists 96 kcal for a 22g pack of Oven Baked Sea Salt. The lower number also describes a smaller portion.
Put grams, kcal and salt side by side for the individual bags, then choose the portion that fits the occasion.
The manufacturers list 0.19g salt for a 22g Walkers Oven Baked Sea Salt pack, 0.39g for an 18g Seabrook Crunchies bag and 0.53g for a 21g Walkers French Fries Ready Salted pack.
Read the salt figure on each inner bag or calculate it only when the label supplies the figures needed to do so.
Tyrrells lists 140–141 kcal per 30g serving for two lentil-crisp flavours. KETTLE Chips lists 516 kcal per 100g for Lightly Salted, while McCoy's lists 533 kcal per 100g for Salted. These are different labelled quantities, not equivalent snack portions.
Check the stated serving or bag weight before comparing a lentil, hand-cooked or ridged option with a smaller snack bag.
The Department of Health & Social Care’s guidance addresses specified retail promotions and placement for businesses selling to England. The Department for Education describes separate requirements for food provided in state-funded schools in England; school-food frameworks also differ elsewhere in the UK.
For school-provided food, check the nation, school type and current school arrangements rather than drawing a UK-wide conclusion from a retail rule.
These examples show why the labelled portion and flavour matter more to this choice than the brand name alone.

Six individual 22g bags provide portions for separate snack occasions. As this is a variety pack, check the nutrition and allergen declaration on each flavour rather than applying figures for Walkers Oven Baked Sea Salt to every bag.
No image available
This multipack supplies six 22g bags of one oven-baked flavour. Check the Cheese & Onion nutrition panel and allergen declaration specifically; the Sea Salt flavour’s figures do not establish this variant’s values.

Five 17g bags offer a smaller stated portion than the 22g oven-baked bags above. Compare kcal and salt per bag, and check the Sour Cream & Onion allergen declaration if ingredients need to be avoided.
No image available
This Barbecue multipack also contains five 17g bags, making the stated portion easy to compare with the other packs here. Check its own nutrition and allergen label rather than assuming it matches the Sour Cream & Onion flavour.
No image available
Six 20g bags offer another individually portioned savoury snack format. Check the Crispy Bacon flavour’s calories, salt, ingredients and allergen declaration before comparing it with potato crisps or other snack bags.
Not on that figure alone. Seabrook lists 81 kcal and 0.39g salt for an 18g bag of Salt & Vinegar Crunchies, compared with Walkers’ 96 kcal and 0.19g salt for a 22g pack of Oven Baked Sea Salt. Compare the portion weight and salt as well as the calories.
No: the cooking description does not state the salt content. Walkers lists 0.19g salt per 22g pack of Oven Baked Sea Salt, but other flavours and brands need their own label check.
No. Those labels address particular dietary criteria, not every ingredient or may-contain warning. Check the allergen declaration on the exact flavour and current pack before serving it to someone with ingredients to avoid.
No: retail promotion rules and school-food requirements address different settings. Department of Health & Social Care guidance concerns specified promotions and placement by businesses selling to England, while the Department for Education sets out separate requirements for food provided in state-funded schools in England. School-food frameworks differ across UK nations, so check the applicable nation, school arrangements and current requirements for the particular setting.
