A guest asks how many calories are in today's special. Your colleague says it has to be on the menu now, "because of the new law". A supplier claims the opposite: that you can't print it without a certified lab behind it. Neither is quite right — and the real answer sits in one clause of an EU regulation almost nobody reads.
The problem isn't that there are no rules. The problem is that two very different rules get run together, and the wrong one keeps getting the attention. Regulation (EU) 1169/2011 — the law that governs food information for every hospitality business in the EU — treats allergens and calories in completely different ways.
Allergens are mandatory everywhere in the EU: fourteen substances, full stop, whichever member state your venue is in. Calories are the opposite: the regulation explicitly exempts "non-prepacked food" — exactly what a restaurant serves — from the mandatory nutrition declaration that packaged products carry. Member states MAY introduce a national rule of their own. At the time of writing, none has done so economy-wide.
Where the confusion usually comes from is the UK: since April 2022, English businesses with more than 250 employees have had to display calories on their menus. That's a real, strictly enforced British rule — and it isn't the EU, it doesn't apply to small venues, and it doesn't even apply to the whole UK.
This guide walks through the seven numbers that separate what's mandatory, what isn't (yet), and what happens if you do it anyway. At the bottom, you can work out what calorie labeling would actually cost your own menu — not in lost sales, but in hours.
Why "is it mandatory" is the wrong question
Most owners ask themselves one question: does the law make me do this? That simple yes/no doesn't actually exist. The real answer depends on which country your venue is in, how many staff you employ, and whether your country has used the opt-in in Article 44(2).
The second reason it's the wrong question: even with no legal requirement, there's still a reason to start anyway. More guests now search for a calorie indication before they book, and a menu that says nothing about it increasingly reads as dated next to one that does.
And the third: the fear behind the question — "if I add the number, I'll sell less" — is largely unfounded. The research further down in this guide shows exactly that. The real obstacle isn't lost revenue; it's the time it takes to work the numbers out.
The 7 numbers behind calorie labeling
The first two lay out the legal contrast, the next two the UK rule that keeps getting misapplied, then the proof that "voluntary" doesn't work, the effect on what a guest actually orders, and finally the clause that could flip all of it overnight. At the bottom, work it out with your own menu.
1. 14: what you already have to disclose
Fourteen substances — gluten, egg, fish, crustaceans, nuts, milk, soya, peanuts, celery, mustard, sesame, sulphites, lupin and molluscs — must be disclosed, verbally or in writing, for every dish on the menu, by every hospitality business in the EU. That's Annex II of Regulation 1169/2011, and it applies with no exception and no minimum size, in every EU member state.
That's the number to measure the rest of this guide against. Allergens aren't a grey area; they're black-and-white mandatory. If you don't have a watertight system for them yet, start there — the free allergen chart tool builds the per-dish overview in the same fourteen categories.
Calories sit in a completely different annex of the same regulation, and that's exactly where the confusion starts.
2. 0: how many EU member states require calorie labeling
Annex V, point 19 of Regulation 1169/2011 explicitly exempts "non-prepacked food" — what a kitchen cooks and serves — from the mandatory nutrition declaration that packaged products carry. For this law, a restaurant isn't a manufacturer; it falls under a different regime entirely.
Article 44(2) of the same regulation lets any member state reverse that with its own national measure. At the time of writing, no EU member state has done so economy-wide — Ireland came closest, and paused the process during Covid without ever restarting it.
Two categories in the same regulation, two completely different rules.
Allergens sit in Annex II of Regulation 1169/2011 and apply with no exception. Calories sit in Annex V, point 19 — explicitly exempted for restaurant meals, unless a country invokes Article 44(2) itself.
3. 250: the UK number you keep half-remembering
The UK is no longer an EU member, but it's the example most European owners actually know — through trade press, through a UK chain with a branch just across the border, or through a supplier active in both markets.
Since 6 April 2022, the Calorie Labelling (Out of Home Sector) Regulations 2021 require every hospitality business in England with more than 250 employees to display calories on every menu, menu board and online ordering page where a guest makes a choice. The rule covers restaurants, cafés, fast-food chains, pubs and caterers — but only counts businesses at 250 employees or above, full-time and part-time combined.
For nearly every independent venue in the EU, that means this simply doesn't apply — not because you're in the wrong country, but because your business is too small for a rule that only exists in England.
4. 2,000: the number that has to ride along on every menu
UK law doesn't just require the calorie figure per dish. It also requires the reference statement, wherever that figure appears: "adults need around 2,000 kcal a day". Without that context, a bare number — "640 kcal" next to a main course — is meaningless to most guests.
That detail is why calorie labeling without context tends to confuse more than it helps. If you ever choose to do this yourself — required or not — carry that reference line along with it: it costs one line, and it's exactly what gives the number meaning.
5. 8% vs. 95%: why "voluntary" doesn't work
Ireland already tried this in 2012 with a voluntary scheme: hospitality businesses could opt in to display calories, with no obligation. A Food Safety Authority of Ireland (FSAI) consultation found 95% of consumers supported calorie posting. The share of businesses that actually ran it: 8%.
Consumers wanted it. Businesses didn't do it — unless they were required to.

6. 47: what actually happens to an order
The fear behind calorie labeling is almost always the same: "if I add the number, I'll sell fewer desserts." A 2025 Cochrane systematic review, pooling 28 studies, gives the honest answer: in restaurants and cafés, guests exposed to calorie labels ordered on average 47 kcal less per order — roughly 7.8% of a 600 kcal reference meal.
Forty-seven kcal is less than one slice of bread. It isn't a collapsed dessert budget or an empty terrace; it's a small, measured effect that mostly shows up as slightly less sauce, a slightly smaller side choice, occasionally a skipped dessert. For most venues, that isn't a revenue problem — it's noise.
So the real cost of calorie labeling doesn't sit at the table. It sits in the kitchen, before the menu is ever printed: the working-out itself. That's exactly what the calculator further down this guide does for you.
7. 1 clause: how this becomes mandatory overnight
Article 44(2) isn't a dead letter. France already uses the exact same mechanism for other food information — its "fait maison" (homemade) label and its origin-of-meat requirement are both national additions bolted onto the same EU base regulation, introduced with no EU-wide warning beforehand.
That means any member state could decide tomorrow to make calorie labeling mandatory, with the rest of the EU unmoved — exactly what Ireland nearly did. "Not mandatory anywhere" is a fact about today, not a promise about next year.
The venues that already do this voluntarily aren't doing it out of fear of a fine that doesn't exist. They're doing it because being ready when the rule does land stops being a scramble — and because some of their guests are already asking for it today.
What calorie labeling would actually cost you
Not lost sales — you now know that number (forty-seven kcal, barely visible). The real cost is the time it takes to work out how many calories are in each dish, and to do it again every time the menu changes.
Fill in your own menu: how many dishes, how many minutes per dish, whose hourly rate, and how often your menu changes. If you already weigh out your dishes in the recipe costing tool, tick that box — the quantities are already known, and that cuts the time considerably.

This works from calculating calories yourself with standard nutrition tables, not a certified lab. Every amount is calculated in your browser; nothing is sent or stored.
This math is deliberately conservative: it assumes you calculate calories yourself from standard nutrition composition tables, not that you bring in a lab. For most independent venues that's realistic too — a certified lab is only needed if you want to make a hard, legally guaranteed claim.
Weigh the result against what one more month of vague answers at the table costs you, and against what it earns you the day your country does decide to make this mandatory.
What you can do today
You don't have to wait for a law that may never arrive — and you don't have to overhaul your whole menu overnight either.
Start with what's already mandatory
- Make sure your allergen chart is watertight for all fourteen substances — that isn't a choice, it's EU law.
- Link every dish on your menu to its ingredient list, so a kitchen change automatically shows up on the card.
- Train the team to answer allergen questions correctly out loud — writing it down isn't enough if nobody can explain it.
Trial calorie labeling small, before you do it everywhere
- Pick five to ten popular dishes and calculate those first — you'll learn the time per dish before tackling the whole menu.
- Carry the reference line ("adults need around 2,000 kcal a day") wherever you show a number — a bare figure with no context confuses more than it helps.
- Watch whether guests actually use it before you expand further.
Track the regulation, not the rumours
- Check yearly with your local hospitality federation whether your country has invoked Article 44(2) — that can change with no EU-wide announcement.
- Don't confuse the UK's 250-employee rule with an EU obligation that doesn't exist.
- Keep your per-dish calculations on file, so you're ready if the rule ever does become mandatory — the work will already be done.
The number that matters isn't the one you thought
Fourteen allergens are mandatory, everywhere, with no exception. Zero EU member states require calorie labeling economy-wide, today. Setting those two numbers side by side is the whole point of this guide — and it's exactly the distinction most owners never hear spelled out.
What you do about calorie labeling before it becomes mandatory is a choice, not a legal duty. The forty-seven kcal the research measures, and the eight percent Ireland's voluntary attempt reached, both say the same thing: the effect on your revenue is small, and the real barrier is the time it takes to work it out.
Work out that time with your own menu in the calculator above, start small with your most popular dishes, and keep an eye on whether your country ever invokes Article 44(2). By then, you'll already have a head start most of your competitors won't.
