For a Bonfire Night snack bar described as high in protein, check more than the grams of protein on the front: the legislation published on legislation.gov.uk sets a threshold of at least 20% of the food’s energy from protein for that claim in Great Britain. Compare the portion you will actually eat, then check the current pack’s ingredients and allergen information before buying bars to share.
If the protein claim is the reason you are buying, compare protein with the bar’s energy rather than choosing by protein grams alone. Pack size matters too: check whether the figures refer to one bar or a multipack.
Vegan and gluten-free suitability answer different questions from protein content. Check the exact flavour’s current label for both the dietary wording you need and its nutrition information.
A portable bar is convenient to hand out, but guests may have different ingredient requirements. Read each current pack’s allergen declaration before sharing, particularly when choosing nut-based bars.
Start with the claim and serving size, then compare the rest of the label against the needs of the people who will eat the bars.
| Priority | What to check | Your needs |
|---|---|---|
| Protein claim | Check protein and energy for the same portion. The legislation published on legislation.gov.uk sets at least 20% of energy from protein as the threshold for a high-protein claim in Great Britain. | If I am shopping specifically for a high-protein bar, a protein figure on its own will not answer my question. |
| Portion and pack | Distinguish figures per bar from figures per 100 g. Check the weight of one bar and how many bars the pack contains. | I want to know what one bar provides when I take a snack out for the evening. |
| Other nutrition | Compare fibre, sugars, energy, saturated fat and salt on the same per-bar basis. Read any no-added-sugar wording alongside the sugars value. | Protein is not my only consideration; I want to compare the whole portion rather than one front-of-pack claim. |
| Ingredients and allergens | Read the current pack’s ingredients, allergen declaration and precautionary wording for the exact flavour. The Food Standards Agency’s guidance explains the requirement to provide allergen information. | Someone sharing these bars may need to avoid a particular ingredient, so I cannot assume that every flavour in a range will suit them. |
| Dietary suitability | Check vegan, dairy-free or gluten-free wording on the exact product where it matters. Do not treat any of these attributes as proof of a high-protein claim. | If I need a particular type of bar, I still want to assess its protein separately. |
Two bars can state similar grams of protein but differ in the proportion of energy that protein provides. The high-protein threshold published on legislation.gov.uk is based on energy share, not a fixed number of grams per bar.
Compare the protein and energy values for the same portion. Using kcal, multiply protein grams by 4 and divide by the portion’s total kcal to check against the 20% threshold.
A protein figure does not tell you the bar’s sugars, fibre or total energy. A no-added-sugar description does not mean that the sugars value is zero.
Compare the complete nutrition panels using the same serving basis, especially if the bars differ in size.
Ingredients and precautionary allergen wording can differ between products and flavours. Individually wrapped bars still need to be checked before they are offered to someone with an allergy.
Read the current pack and do not serve a bar to someone for whom its declared ingredients or precautionary wording are unsuitable.
Alpen’s cited No Added Sugar product is muesli, with nutrition stated for a 45 g serving. That does not make it an equivalent single-bar portion for an outdoor event.
Compare actual snack bars when a portable, individually portioned product is what you need.
These examples describe particular products or ranges, not every bar made by each brand; check the exact flavour and current pack before choosing.
Its Peanut & Chocolate protein bar is a 40 g portion; Nature Valley UK describes it as providing around 10 g protein and around 4 g fibre.
Tesco Groceries lists 10.4 g protein per 40 g bar for the Peanuts, Almonds & Salted Caramel variant.
The Original Oat Protein Flapjack is an oat-based option for shoppers comparing plant-based bars.
Tesco Groceries describes the Protein Peanut Butter Bar as having no added sugar and 7 g plant protein.
Graze’s Oat Boost products are flapjacks, so compare an exact bar’s label rather than assuming its range name establishes a protein claim.
Alpen’s cited No Added Sugar product is muesli rather than an individually portioned snack bar.
These Joybuy listings are multipacks of snack bars to compare for Bonfire Night. Check the nutrition and allergen details on the exact pack when deciding whether a flavour meets your protein and dietary requirements.

A multipack for taking individual bars to an event. Check the current pack’s milk and soya declarations; choose another option if you require a vegan or gluten-free bar.

This 12-bar pack offers a caramel-flavoured option for an outdoor gathering. Check the current milk and soya information and any precautionary wording for gluten, peanuts and nuts; it is not a vegan or gluten-free choice.

Consider this peanut-butter flavour only after checking that its ingredients suit everyone who may receive a bar. The pack contains 12 × 50 g bars; check the current peanut, milk and soya declarations. It is not a vegan or gluten-free choice.

A four-bar pack with a different portion size from the 50 g Grenade multipacks above. This option contains wheat and is not suitable if you need a gluten-free or vegan bar; check the current milk and soya declarations too.
No image available
This four-pack provides 40 g nut-flavoured bars for comparing with other single-bar portions. Check the current almond, peanut, milk and soya declarations before sharing; it is not a vegan option.
Not necessarily. For a high-protein claim in Great Britain, the legislation published on legislation.gov.uk requires protein to provide at least 20% of the food’s energy. Check the protein and energy values for the same serving rather than judging by protein grams alone.
Compare the stated fibre and protein per bar, then assess any high-protein claim separately. Nature Valley UK describes its 40 g Peanut & Chocolate bar as providing around 4 g fibre and around 10 g protein; the figures for another flavour may differ.
Check each current pack before offering it to anyone else. Nut-based recipes and their allergen wording differ, and a bar must not be served to someone for whom its declared ingredients or precautionary wording are unsuitable.
No. Those descriptions address different attributes; neither establishes that protein supplies at least 20% of the bar’s energy. No added sugar also does not mean zero sugars, so read the sugars value on the nutrition panel.
