Occasional car boot sale hosts
Count the portions that can be handed out without opening them. Keep the outer pack as well as the wrappers available wherever it carries ingredient or allergen information.
Who is buying the bars?
The right pack depends on whether you need several sealed handouts, particular dietary options or a smaller selection for known recipients.
Hosts serving people with different dietary needs
Check each flavour separately. A bar described as vegan or gluten-free can still contain nuts; those claims do not establish suitability for someone with a nut allergy.
Buyers choosing protein-style bars
Compare the stated protein amount per bar and the pack count with the number of people you expect to serve. Check allergens too: Nature Valley’s peanut protein bar, for example, contains peanut, soya and milk, according to Nature Valley UK.
What should you check?
Start with the sealed handout size, then check the label for every flavour. Consider how the bars will be offered before opening or repacking any food.
| Priority | What to check | Your needs |
|---|---|---|
| Sealed portions | Compare the bar count with the number of separately packaged portions. Nature Valley UK describes its 20-bar Crunchy Variety Family Pack as 10 two-bar portions; compare nutrition for the 42 g twin portion if that is what you will hand out. | I want enough sealed refreshments for the people I expect, without counting a twin portion as two separate handouts. |
| Ingredients and allergens | Read the exact flavour labels and any information on the outer pack. Check ingredients and allergen statements before offering bars to people with dietary restrictions; do not treat a range-wide claim as a label for every variant. | People choosing a bar should be able to inspect its ingredient and allergen information, particularly where nuts, milk, soya or cereals matter. |
| Dietary claims and nutrition | Check vegan, gluten-free or dairy-free wording on the exact pack. Compare sugars, fibre and protein using the labelled serving size; a 35 g single bar and a 42 g twin portion are different handouts. | I may want a particular dietary option or portion size, but I do not want a “protein” or “no added sugar” claim to stand in for the full label. |
| How food is offered | Decide whether bars will remain manufacturer-prepacked or be opened and repackaged. GOV.UK and Food Standards Scotland set out labelling requirements for food businesses selling prepacked-for-direct-sale food; the local authority can advise how registration rules apply to your activity. | If I plan to sell food regularly or change its packaging before sale, I need to check the applicable requirements before the event. |
Common buying mistakes
-
Counting every bar as a separate handout
Nature Valley UK lists its Crunchy Variety Family Pack as 20 bars arranged in 10 twin portions. Handing out unopened twin portions gives you 10 sealed handouts, not 20.
Check the packaging arrangement as well as the headline count, then choose a format that matches the portions you intend to offer.
-
Assuming a dietary claim settles allergy suitability
Fruit-and-nut bars can be marketed as vegan and gluten-free while still containing nuts. Other bars in this category list ingredients such as peanuts, milk and soya.
Keep the exact product’s label available and let recipients check it. Do not describe a bar as suitable for a particular allergy unless its current label supports that description.
-
Judging nutrition from the front of the pack
Serving sizes and recipes vary. In its November 2025 review of 458 snack bars from 10 major retailers, Action on Salt & Sugar classified 37% as high in sugars; that category figure does not describe every bar.
Compare the “of which sugars”, fibre and protein figures for the portion you will actually hand out, alongside its ingredients.
-
Opening or repacking bars without checking the rules
For a food business, packaging food before it is selected or ordered at the place where it is sold can bring it within prepacked-for-direct-sale labelling rules. GOV.UK and Food Standards Scotland describe requirements for the food name, full ingredients list and emphasised allergens.
If you intend to split, wrap or relabel bars, ask the relevant local authority which food-business and labelling requirements apply to your activity before the sale.
Brand and range references
These examples show formats and label details worth comparing; a brand’s range description does not replace the information on a particular pack.
Graze
Graze describes snacks made with ingredients including wholegrains, fruit and nuts, and says all its snacks are vegetarian and most are vegan.
- Ingredient-led options may be worth checking when a vegetarian snack is wanted.
- Check the count, ingredients and allergens of the specific multipack; the brand-wide descriptions do not establish those details.
Nature Valley
Nature Valley UK lists a Crunchy Variety Family Pack of 20 bars arranged as 10 twin portions in three flavours.
- The twin-portion format gives a clear count for handing out unopened packs.
- Nature Valley lists oats and soya for this pack, with possible nuts, peanuts and wheat; check the current pack because recipes can change.
Alpen
Alpen Light Chocolate & Fudge is a 19 g cereal bar; Weetabix Cereals lists 65 kcal and 4.2 g fibre per bar.
- Its per-bar figures allow comparison with the portion you intend to offer.
- Weetabix Cereals says this variant is not suitable for people with nut allergies; check its full label for other allergens.
Eat Natural
Morrisons lists an Eat Natural Salted Caramel & Nuts three-pack with each bar individually wrapped.
- The format suits a small number of separate handouts.
- The listed allergen information includes peanuts, almonds, milk and soya, so check the delivered pack before offering it.
Nakd
Ocado lists a nākd. fruit-and-nut variety box containing 18 × 35 g bars across six flavours, described as vegan, gluten-free and dairy-free.
- The named flavours provide a choice within one box.
- Fruit-and-nut ingredients still require an allergy check for each flavour; “no added sugar” does not mean the bars contain no sugars.
TREK
TREK describes its Protein Flapjacks as providing 9 g plant-based protein and its High Protein bars as providing 15 g; it describes all TREK bars as plant-based.
- The range offers protein-labelled formats for recipients seeking them.
- Check the exact multipack’s count, ingredients and allergens rather than applying range-level statements to every bar.

Questions about choosing and selling bars
Can I offer bars in their original wrappers?
Yes. Keeping bars manufacturer-prepacked helps preserve access to their ingredient and allergen information; retain the outer packaging too if it carries details needed to understand the individual bars. GOV.UK guidance for England, Northern Ireland and Wales and Food Standards Scotland guidance address the availability of allergen information when food is offered.
What changes if I open a multipack and repackage the bars?
If a food business packages food at the place where it is offered or sold before a customer selects or orders it, the food can fall under prepacked-for-direct-sale rules. GOV.UK guidance for England, Northern Ireland and Wales and Food Standards Scotland guidance require applicable PPDS food to carry its name and a full ingredients list with allergens emphasised. Check how the rules apply before changing the packaging.
Do I need to register to sell snack bars at a car boot sale?
That depends on whether the activity is a food business and how it is organised. GOV.UK says a local authority may decide that very limited, infrequent activity does not need registration; the Food Standards Agency says a new food business should register at least 28 days before trading. Food Standards Scotland says occasional provision is unlikely to need registration, while food businesses must register at least 28 days before opening. Ask the relevant local authority about your plans.
Are vegan or gluten-free bars suitable for someone with a nut allergy?
Not automatically. Ocado describes the nākd. Fruit & Nut Bars Variety Pack as vegan and gluten-free, but those descriptions do not remove its nut ingredients. Check the delivered wrapper and allergen statement for the exact flavour rather than relying on a separate dietary claim.
How can I compare sugars across different multipacks?
Read the “of which sugars” figure for the portion you will hand out, and check its serving size and ingredients. Nature Valley UK gives nutrition for a 42 g two-bar portion in its Crunchy Variety Family Pack, whereas Ocado lists the nākd. variety flavours as 35 g bars; comparing their per-serving figures without noting those different portions would be misleading.
