For car boot sale refreshments, start with sealed bars that keep the information buyers need on each unit you intend to sell. Compare pack counts and bar sizes, then check the exact flavour’s ingredients, allergens, date and storage instructions; if your activity is a food business, the Food Standards Agency’s registration requirements also need attention before trading.
Who are you buying for?
Sellers offering sealed refreshments
Choose a pack with a suitable number of bars, and check what information remains on each wrapper if you plan to sell the bars separately. Business Companion’s guidance for England and Wales distinguishes prepacked food bought for resale from food packed for direct sale.
Sellers expecting protein-focused shoppers
Compare the declared protein and sugars for the exact flavour and bar size. For example, PhD lists 21 g protein and 1.2 g sugars for its 64 g Smart Bar Chocolate Brownie; those figures should not be applied to other flavours.
Sellers offering a vegan-labelled choice
Identify the vegan product separately, but still check its own ingredient and allergen declaration. A vegan label does not establish that a bar is suitable for someone avoiding a particular allergen.
What should you check before buying?
Check the units you would actually put on the stall before comparing flavours or nutritional declarations across packs.
| Priority | What to check | Your needs |
| Pack quantity |
Check the number of bars and weight per bar. Confirm that the pack format suits how you intend to offer them. |
I need enough individual refreshments for the stall without mistaking a larger box for larger bars. |
| Nutrition by flavour |
Read protein and sugars per bar for the named flavour and serving size. Check any sweetener warnings on its label. |
Some customers may ask for a particular protein or sugars figure; I want to describe the bar I am selling, not another flavour in the range. |
| Ingredients and allergens |
Check each flavour’s ingredient and allergen declaration. If selling bars separately, check what information remains available with each unit. |
I want buyers to be able to inspect the relevant information rather than relying on a broad label such as ‘vegan’. |
| Outdoor display |
Check package condition, date marking and the manufacturer’s storage instructions. Plan how to follow those instructions at the stall. |
The bars may be on display outdoors, so I need to know how the particular products should be stored. |
What can go wrong at the stall?
-
Assuming one dietary label answers every allergen question
A vegan or protein-bar description does not identify every ingredient a buyer may need to avoid. Ingredient and allergen information can also differ between flavours.
Keep the original packaging available and check the exact product declaration before describing a bar’s suitability.
-
Assuming an occasional stall needs no food-business checks
If the activity is a food business, the Food Standards Agency says registration with the local authority is required at least 28 days before trading. The requirements for a particular stall depend on its activity and location.
Ask the relevant local authority and event organiser what applies before the sale, and check the products’ storage instructions when planning your display.
Brand ranges to compare
Grenade
Grenade lists protein-bar bundles containing multiple packs on its UK range page.
- A 24-bar bundle is listed for buyers considering a larger order.
- Check the selected flavours’ own nutrition, allergen and storage information rather than applying range-wide descriptions to every bar.
PhD
PhD lists 12-packs in its Smart Bar range and a separate Smart Plant option.
- PhD lists 21 g protein and 1.2 g sugars for the 64 g Smart Bar Chocolate Brownie; its Smart Plant Salted Caramel listing states 20 g protein per bar.
- Confirm the particular flavour’s ingredients and warnings; the figures for one bar do not describe the whole range.
Barebells
Barebells lists both single-flavour 12-packs and a 12-bar selection box.
- Barebells states 20 g protein per bar for its Cookies & Cream product.
- Allergens vary by flavour: Barebells lists milk, hazelnuts and soy for Hazelnut Nougat, with additional possible traces.
Myprotein
Myprotein’s UK snack range includes protein bars, including Soft Protein Bar and Layered Bar products.
- The range offers different product lines to inspect for the stall’s intended selection.
- Check an individual listing and wrapper for pack count, bar size and flavour-specific information.
Quest
Quest Nutrition describes protein bars on its own range site.
- Quest’s own site describes bars with 20–21 g protein, depending on product.
- Check the UK retail product and its wrapper for the particular formulation, ingredients and labelling before offering it at a stall.

Frequently asked questions
Can I sell bars separately from a multipack?
Check what information remains available with each individual unit before offering it separately. Business Companion’s England-and-Wales guidance treats food bought by a separate business for later sale to consumers as prepacked; its prepacked-food guidance covers particulars including ingredients, allergens and date marking. Do not rely on information printed only on an outer pack when selling a bar on its own.
Do I need to register to sell protein bars at a car boot sale?
If your activity is a food business, the Food Standards Agency says you must register with the local authority at least 28 days before trading. Ask the relevant local authority whether your particular activity falls within that requirement, and check the event organiser’s conditions too.
Is a vegan protein bar suitable for someone avoiding allergens?
Not necessarily. Vegan status and allergen suitability answer different questions: check the ingredients and allergen statement for the exact bar rather than treating its vegan description as an allergen declaration.
What should I check before displaying bars outdoors?
Check each product’s date marking, package condition and storage instructions, then plan the display around those instructions. Food Standards Agency food-safety guidance identifies packaging, storage and distribution conditions, and shelf-life information as matters to consider.
