Start with the Fairtrade mark: the Fairtrade Foundation says its classic black-background mark covers every ingredient in the bar that can be Fairtrade-certified. If you prefer a less intense cocoa flavour, compare the Fairtrade claims on Divine’s 70% bar and M&S’s 75% bar before considering an 85% option; check the current pack for ingredients, nutrition and allergens. Chocolate contains caffeine, so a midnight portion may not fit your routine if caffeine affects your sleep.
If Fairtrade is a requirement rather than a preference for general responsible sourcing, read the mark on the particular bar. The Fairtrade Foundation says its classic black-background mark covers all ingredients that can be Fairtrade-certified.
If you are unsure how much cocoa intensity you enjoy, compare the labelled 70% and 75% Fairtrade options before choosing an 85% bar. Check the exact pack for flavour additions and nutrition values too; cocoa percentage does not tell the whole story.
Chocolate contains caffeine. University College London Hospitals NHS Foundation Trust advises avoiding caffeine after 2pm in its sleep-hygiene guidance and explicitly includes chocolate, making a midnight portion a poor fit if caffeine affects your sleep.
Choose the certification scope you require first, then compare the particular bars for taste, label details and whether chocolate fits your late-night routine.
| Priority | What to check | Your needs |
|---|---|---|
| Fairtrade coverage | Look at the mark on the exact bar and read which ingredients it covers. The Fairtrade Foundation says the classic black-background Fairtrade Mark covers all ingredients that can be Fairtrade-certified; a general responsible-sourcing statement is not the same claim. | I want to know whether Fairtrade applies to the bar’s certifiable ingredients, rather than relying on a broad claim about the maker. |
| Cocoa and flavour | Compare the stated cocoa percentage and ingredients. Divine describes a Fairtrade 70% bar, while M&S describes Fairtrade 75% and 85% bars; check the nutrition panel per 100g on the current pack rather than treating cocoa percentage as a nutrition rating. | A less intense dark-chocolate flavour may suit me better than an 85% bar, or I may actively prefer the stronger cocoa taste. |
| Midnight timing | Consider when you plan to eat chocolate and whether caffeine affects your sleep. University College London Hospitals NHS Foundation Trust includes chocolate among caffeine sources in guidance advising people to avoid caffeine after 2pm. | If caffeine keeps me awake, I would rather have chocolate earlier than make it a midnight snack. |
| Allergens | Read the ingredients and precautionary allergen statement on the physical pack. The Divine 70% listing warns of possible gluten, milk and nuts; the M&S 75% and 85% listings flag milk, nut and peanut allergy unsuitability. | For an allergy, I need the current label for the exact bar, not an assumption based on its dark-chocolate name or an older online description. |
A maker’s sourcing programme or certified-cocoa statement does not, by itself, establish the Fairtrade status of a particular bar.
If Fairtrade is essential to your choice, check the exact product’s mark and what that mark covers before buying.
A higher cocoa percentage may change the flavour you experience, but it does not replace the ingredients or nutrition panel when comparing bars.
Pick a cocoa level you expect to enjoy, then compare sugars and saturated fat per 100g on the current packs.
Chocolate remains a caffeine source. University College London Hospitals NHS Foundation Trust advises avoiding caffeine after 2pm in its sleep-hygiene guidance.
If caffeine affects your sleep, have chocolate earlier or choose something else for a midnight snack.
Ingredients and precautionary statements matter for the individual bar, and the M&S product pages warn that product information can change.
For an allergy or intolerance, inspect the current physical pack and do not choose a bar whose declaration is unsuitable for you.
These brand and range details help distinguish a stated Fairtrade product claim from other sourcing or flavour choices; they do not establish the status of every bar a brand makes.
A brand to consider when comparing dark bars whose own product pages explicitly name Fairtrade ingredients.
A retailer range with product pages describing Fairtrade 75% and 85% dark-chocolate options.
A dark-chocolate range with distinct 74% and 100% cocoa products for shoppers comparing ingredients and cocoa levels.
An option for comparing a stated 70% cocoa bar with the brand’s own sourcing programme.
A range reference for shoppers comparing dark-chocolate formats and cocoa percentages.
These four listings offer 70% or 85% dark-chocolate options for comparing cocoa levels and variants. If Fairtrade is a requirement, check the current pack’s mark and its scope for the bar you choose.

A 70% cocoa option if you want to start below the 85% bars in this selection. For a Fairtrade requirement, confirm the mark and ingredient coverage on the current pack; check its allergen statement and consider whether chocolate’s caffeine suits your midnight routine.
No image available
Consider this 85% cocoa variant if you enjoy a stronger cocoa flavour. Check the current pack for the Fairtrade mark’s scope and allergen warnings; cocoa percentage does not tell you whether a late-night portion will suit your sleep routine.
No image available
Another 85% cocoa choice for someone who prefers an intense dark-chocolate flavour. Check the physical pack for the precise Fairtrade claim and for ingredients and allergen warnings before deciding whether this variant suits you.

This 70% cocoa bar adds raspberry flavour to the choice. Check the current pack for its exact Fairtrade claim and dietary suitability: the product information describes it as vegan-friendly but also gives a milk-allergen statement, so do not rely on the vegan wording for an allergy decision.
Read the mark on the exact bar and what it covers. The Fairtrade Foundation says its classic black-background Fairtrade Mark means all ingredients that can be Fairtrade-certified are Fairtrade-certified. Do not treat a general ethical- or responsible-sourcing statement as the same product claim.
Choose a cocoa level whose flavour you expect to enjoy, rather than assuming the highest percentage is the right choice. Divine describes a Fairtrade 70% bar and M&S describes Fairtrade 75% and 85% bars; compare their current ingredients and nutrition panels per 100g, and consider caffeine separately from cocoa percentage.
Yes. University College London Hospitals NHS Foundation Trust includes chocolate among caffeine sources in its sleep-hygiene guidance and advises avoiding caffeine after 2pm. If caffeine affects your sleep, have chocolate earlier or choose another midnight snack.
Do not assume so from either description. The Divine 70% product page warns of possible milk and nuts, while the M&S dark-bar pages flag milk, nut and peanut allergy unsuitability. Read the current physical pack for the exact product before choosing it.
No. The Department for Education’s school-food standards concern food provided in school settings in England, not a personal midnight snack bought for home. Its school-food guidance addresses chocolate and confectionery across the school day; it is not a UK-wide prohibition on buying chocolate.
