Who is choosing these bars?

Car boot sellers offering wrapped snacks

Keep each bar with its own ingredient and allergen information so visitors can check the flavour they are offered. If selling food amounts to operating a food business, check the applicable registration and labelling duties before trading.

Vegan or dairy-free shoppers

Plant-based bars may meet a dietary preference while still containing peanuts, soya or wheat, or carrying precautionary warnings about other allergens. Check the particular bar rather than relying on the front-of-pack description alone.

Shoppers comparing protein per bar

If protein content matters for the refreshment on offer, compare the stated amount for an individual bar as well as its ingredients. The word “protein” in a product name does not tell you how much one bar provides.

What should you check before buying?

Start with the dietary requirement the bar must meet, then check the individual serving and how its label will stay with it at the sale.

PriorityWhat to checkYour needs
Dietary requirement Check the exact flavour’s dietary claim, ingredients and “may contain” statement. Vegan, dairy-free and gluten-free describe different requirements; none is a blanket allergy assurance. I need to offer a bar that matches a named requirement, while leaving visitors with the information to check any allergens they must avoid.
Protein per bar Compare protein and energy on the same per-bar or per-serving basis, noting the bar size. Do not substitute a per-100g figure for what one bar provides. For a protein-focused snack, I want to know what is in the individual bar I will hand over, not just its product category.
Packaging and flavours Check whether each bar has its own wrapper and whether a multipack contains different flavours. Keep the correct ingredient information with each bar. A mixed box might suit general refreshments, but I would use individually checked flavours when offering a bar for a specific dietary requirement.
Selling food Establish with the local authority whether the activity is a food business and check the organiser’s conditions. The Food Standards Agency says a new food business must register at least 28 days before trading or food operations start. In England, Wales and Northern Ireland, applicable food prepacked for direct sale needs its name and a full ingredients list with allergens emphasised. If I plan to sell or pack refreshments, I need to check the rules for that activity before the event rather than assume they are the same as bringing snacks for personal use.

What can go wrong?

  • Assuming vegan means suitable for every allergy

    Barebells Vegan Fudge Brownie contains wheat and soya and carries warnings about milk, peanuts, tree nuts and sesame. Myprotein’s vegan Peanut Butter Protein Bar contains peanuts.

    For a person avoiding a named allergen, check the ingredients and precautionary statement on the exact flavour’s wrapper.

  • Using one mixed-box description for every bar

    Grenade says flavours in its selection box can vary and directs buyers to the individual packaging for allergen information.

    Keep every wrapper with its bar, or choose a single, individually checked flavour for a particular dietary requirement.

  • Assuming protein bars contain similar amounts of protein

    Product statements differ: Tesco describes its Nakd Cherry bar as providing 6g of protein, while Barebells states 15g for its Vegan Fudge Brownie bar and PhD states 20g per serving for Smart Plant.

    Compare the amount per actual bar alongside its ingredients and serving size.

  • Packing food for sale without checking the rules

    Food Standards Agency guidance says food-business registration is required before a new business starts trading. In England, Wales and Northern Ireland, the stated ingredient and allergen-labelling requirements for food prepacked for direct sale can apply at temporary outlets.

    Before making, portioning or packing food to sell, ask the relevant local authority which requirements apply and check the event organiser’s conditions. Keep bought-in bars in their original packaging.

Relevant brands and retailers

Brand ranges and retailer categories can help narrow a search, but suitability for a dietary requirement rests with the particular product and flavour.

Grenade

Grenade offers protein bars and mixed selection boxes.

  • Grenade describes its protein-bar range as providing over 20g of protein per bar.
  • Its selection box can contain varying flavours and carries warnings covering several allergens; check each wrapper separately.

PhD

PhD’s Smart Plant range offers vegan protein bars.

  • PhD states that Smart Plant provides 20g of protein per serving on the product page supplied.
  • The listed Salted Caramel ingredients include soya protein and peanut paste, so its vegan description does not establish suitability for avoiding those ingredients.

Myprotein

Myprotein lists a vegan Peanut Butter Protein Bar.

  • Its UK product page states 8g of plant protein per bar.
  • It contains peanut ingredients; Myprotein says it is not suitable for people with peanut or nut allergies.

Quest

Quest describes protein bars on its US-facing website.

  • Check the ingredients and allergen statement of any particular UK-sold Quest bar rather than applying general US range descriptions to it.

Barebells

Barebells offers a Vegan Fudge Brownie protein bar.

  • Barebells states that this 55g bar provides 15g of protein.
  • The product contains wheat and soya and carries precautionary warnings for milk, peanuts, tree nuts and sesame.

Tesco

Tesco is a retailer with snack-bar listings, including Nakd Cherry Protein Bars.

  • Tesco lists the Nakd Cherry bar as vegan, gluten-free and dairy-free.
  • The same listing says it contains peanuts and may contain soya and nuts; check the individual product, not just the shopping category.

Frequently asked questions

Is a vegan protein bar automatically suitable for someone avoiding milk?

No. A vegan description does not replace the exact flavour’s allergen statement: Barebells Vegan Fudge Brownie carries a precautionary warning for milk, as does Myprotein’s vegan Peanut Butter Protein Bar. Check the individual wrapper against the person’s stated requirement.

Does gluten-free mean nut-free or dairy-free?

No. Tesco lists Nakd Cherry Protein Bars as gluten-free and dairy-free, but says they contain peanuts and may contain soya and nuts. Check each allergen requirement separately.

Can I use a mixed selection box for free-from refreshments?

Only after checking the individual bars against the requirement you intend to meet. Grenade says flavours in its selection box can vary and directs buyers to each wrapper for allergen information; a box-level description cannot stand in for every flavour’s label.

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

If the activity is a new food business, the Food Standards Agency says it must be registered with the local authority at least 28 days before trading or food operations start. Ask the relevant local authority whether your planned activity is a food business, and check the event organiser’s conditions.

What changes if I pack food myself before selling it?

In England, Wales and Northern Ireland, Food Standards Agency guidance requires applicable food prepacked for direct sale by a food business to carry its name and a full ingredients list with allergenic ingredients emphasised; temporary outlets can fall within its scope. Check how the rules apply to your packing and selling arrangement with the local authority before trading.
