Who is choosing these bars?

Car boot sale sellers stocking sealed refreshments

Individually wrapped bars can be displayed without preparing food at the stall. Keep each product's ingredients and allergen information accessible so customers can check the bar they are buying.

Buyers comparing calories

Compare the declared kcal for one bar alongside its weight. A claim such as “natural”, “no added sugar” or “high protein” does not replace the nutrition panel.

Sellers offering dietary choices

A clearly labelled vegan or gluten-free option may broaden the choice at a stall. Check its ingredients and allergen statements separately: neither claim means a bar is nut-free.

What should you check before stocking them?

Start with the serving customers will actually buy, then check dietary labels, allergens and how the bars will be sold.

PriorityWhat to checkYour needs
Calories per bar Compare kcal for one wrapped bar and note its weight. Use the per-100 g value if you also want to compare bars of different sizes on the same basis. I want customers to see the amount in the portion they will eat, without mistaking a smaller bar for a like-for-like nutrition difference.
Sugars and claims Read total sugars per bar as well as any “no added sugar”, protein or fibre claim. Check the nutrition panel rather than treating one claim as a verdict on the whole bar. A fruit bar may suit the display, but I do not want to describe it as low in sugar just because it has no added sugar.
Ingredients and allergens Check the current wrapper for ingredients, declared allergens and may-contain statements. Read vegan and gluten-free claims alongside that information. Customers need to be able to check the exact bar before choosing, particularly when a mixed display includes nuts, milk, soya or cereals containing gluten.
Stall arrangements Keep manufacturer-sealed bars in their labelled wrappers. If you pack food yourself before sale, check whether prepacked-for-direct-sale labelling rules apply; ask the relevant local authority about registration for your activity. Before I put refreshments on a stall, I need to know which requirements apply to the way and frequency with which I sell them.

Common stocking mistakes

  • Choosing from front-of-pack claims alone

    Action on Sugar's 2025 snack-bar audit reported that 37% of the bars it reviewed met UK front-of-pack thresholds for high sugars and 55% for high saturated fat. A protein or fibre claim does not describe those other values.

    Compare kcal, sugars and saturated fat using the nutrition panel, and keep the serving size in view.

  • Calling a no-added-sugar bar low in sugar

    Tesco's listing for Nakd Berry Delight gives 17 g sugars per 35 g bar despite its no-added-sugar claim.

    Describe the claim accurately and let customers inspect the total-sugars figure rather than substituting one statement for the other.

  • Making allergens hard to check in a mixed display

    Customers choosing between different bars need the ingredients and allergen statement for the particular product they pick up. A vegan or gluten-free label does not answer every allergy question.

    Leave bars in their original wrappers, avoid an unlabelled mix of loose products and check current packaging when restocking. Food Standards Agency guidance sets out additional ingredients and allergen-labelling requirements where a food business packs food for direct sale.

  • Assuming a temporary stall is exempt from food-business rules

    Food Standards Agency guidance says food-business registration can apply to temporary stalls. Its guidance on very limited and infrequent food activity says the local authority may decide registration is unnecessary; that is not an automatic exemption from providing safe food.

    Ask the relevant local authority what applies to your activity before stocking food for resale.

Brand and product-line references

These examples describe particular listed products, not every bar made by each brand or the products available in the Joybuy selection below.

Graze

Waitrose lists Honey Oat Boosts at 129 kcal per 30 g bar; Tesco lists Cherry Bakewell Oat Boosts at 131 kcal per 30 g bar.

  • Both listings describe these oat-bar products as high in fibre.
  • Check the current wrapper for allergens: the reviewed Honey variety contains oats and soya flour, while Cherry Bakewell contains almonds.

Nakd

Tesco lists Berry Delight as a 35 g fruit-and-nut bar with 133 kcal per bar and vegan, gluten-free and dairy-free claims.

  • Its labelled dietary claims offer a different choice from the reviewed oat bars.
  • It contains cashews. The same listing gives 17 g sugars per bar, so its no-added-sugar claim should not be read as a low-sugar claim.

Nature Valley

Nature Valley lists its Protein Peanut & Chocolate bar at 196 kcal, about 10 g protein and about 4 g fibre per 40 g bar.

  • Consider this particular bar when its declared protein amount matters more to the selection than choosing from the lower-kcal examples above.
  • The product contains peanuts, soya and milk ingredients; check the current pack for the complete allergen statement.

Eat Natural

Waitrose lists Dark Chocolate Almonds, Cranberries & Coconut at 193 kcal per 40 g bar.

  • The listing describes this fruit-and-nut product as gluten-free and a source of fibre.
  • It contains almonds and peanuts; inspect the wrapper for its full allergen and may-contain statements.

TREK

TREK describes Cocoa Oat as a vegan protein flapjack and gives 227 kcal and 9 g protein for a 50 g bar.

  • Its stated plant-protein content may be relevant when comparing labelled protein amounts.
  • An ASDA listing describes a 40 g Cocoa Oat pack. Check the weight and nutrition panel of the version you intend to stock before comparing per-bar figures.

Alpen

Alpen's referenced UK product page describes its muesli range.

  • If considering an Alpen snack bar, compare the exact product's current wrapper and per-bar nutrition panel rather than using muesli information.

Snack bars on Joybuy

These oat, cereal and fruit-flavoured bar multipacks are options to assess for a car boot sale refreshment display. Compare each pack's current per-bar nutrition and allergen label before choosing stock; the retailer-listed examples above are not calorie figures for these separate listings.

Graze Oat Boosts Lemon Blueberry, four 30 g bars

Graze Oat Boosts Lemon Blueberry, 4 × 30 g

A four-bar oat option for the refreshment display. Compare kcal on the current 30 g bar label; the product information identifies oats and soya among its allergens and advises checking the pack for further warnings.

Graze Protein Bites Cocoa, Vanilla Oat Squares, four 30 g bars

Graze Protein Bites Cocoa, Vanilla Oat Squares, 4 × 30 g

For a 30 g oat-square option, check the current per-bar kcal and protein figures rather than judging it by “Protein Bites” in the name. The product information identifies oats and soya as allergens and advises checking the pack for other warnings.

Special K Dark Chocolate Snack, six 21.5 g bars

Special K Dark Chocolate Snack, 6 × 21.5 g

The stated 21.5 g bar is smaller than the 30 g and 35 g examples discussed above. Compare both kcal per bar and per 100 g; the product information identifies wheat, barley, oats, milk and soya among the allergens.

View on Joybuy
Graze Oat Boosts Cherry Bakewell, four 30 g bars

Graze Oat Boosts Cherry Bakewell, 4 × 30 g

This is the same named variety as the Tesco-listed example, but use the current pack's kcal figure when stocking it: the supplied product information gives a different per-bar figure from that listing. The product information identifies oats and almonds.

Kellogg's Strawberry Nutri Grain Bars, six-pack, 222 g

Kellogg's Strawberry Nutri Grain Bars, 6-pack, 222 g

A strawberry bar multipack to compare by the nutrition information for one bar, not only the 222 g pack weight. The product information identifies wheat, soya and milk allergens and advises checking the wrapper for may-contain statements.

Questions about selling snack bars

Can I call these bars “low calorie”?

Use the declared kcal per bar rather than treating “low calorie” as an established claim for these products. Waitrose lists Graze Honey Oat Boosts at 129 kcal per 30 g bar, Tesco lists Graze Cherry Bakewell Oat Boosts at 131 kcal per 30 g bar and Tesco lists Nakd Berry Delight at 133 kcal per 35 g bar; check the current pack of any bar you stock.

Does “no added sugar” mean a bar is low in sugar?

No. Tesco lists Nakd Berry Delight as having no added sugar but gives 17 g total sugars per 35 g bar. Check total sugars on the nutrition panel when that distinction matters to your selection.

Do I need to register to sell sealed bars at a car boot sale?

Food-business registration can apply to a temporary stall, according to Food Standards Agency guidance, so ask the relevant local authority about your planned activity before selling. Its guidance says the authority may decide that very limited and infrequent food activity does not need registration. Food Standards Scotland states that food businesses in Scotland must register with their local authority at least 28 days before opening.

What allergen information should customers be able to check?

Keep manufacturer-prepacked bars in their original labelled wrappers so customers can inspect the ingredients and allergens for the exact product. If a food business packs food before it is selected for sale, Food Standards Agency guidance says prepacked-for-direct-sale food must carry its name and a full ingredients list with allergenic ingredients emphasised.

Is Nakd Berry Delight suitable for every vegan or gluten-free customer?

No single dietary claim establishes suitability for every customer. Tesco lists Nakd Berry Delight as vegan and gluten-free, but it contains cashews; customers should also inspect the current pack's full allergen and may-contain statements.
