You've seen the sticker. Green and black, a number from 5 down to 0, usually stuck to the door or propped in the window of a café or takeaway. Most people assume every food business has to show it. They don't. Whether displaying that rating is a legal duty or just a polite gesture depends entirely on which part of the UK the business sits in, and that single fact catches out a surprising number of people.
So let's sort out who must, who needn't, and what you should do when there's no sticker to be seen.
The split across the four nations
There isn't one UK-wide rule here, which is the root of most of the confusion. Food hygiene is devolved, so each nation runs its own version of the scheme with its own legislation behind it.
In Wales and Northern Ireland, display is mandatory. By law. A business covered by the scheme has to show its sticker somewhere customers can see it clearly before they walk in or order, and hand the rating over if asked.
In England, display is voluntary. The Food Standards Agency leans on businesses hard to do it, and most decent ones do, but no law forces them.
Scotland runs a different scheme altogether, and display there is also voluntary. More on Scotland below, because it doesn't even use the same wording.
That's the shape of it. Two nations where the sticker is compulsory, two where it's a choice. If you only remember one thing, make it that.
Wales: the rating must be on show
Wales brought in mandatory display back in 2013, and it's been the model other places look at. A business has to display its sticker in a spot where you'd reasonably notice it before entering or buying — the front door, a window, near the till. Not tucked behind the cigarettes or face-down in a drawer.
The rules go further than just sticking it up. The displayed rating has to be the current one. If a business is reinspected and the score changes, the old sticker comes down and the new one goes up. Showing a stale rating, or one that's been doctored, is an offence in its own right.
Enforcement falls to the local authority, and they can issue fixed penalty notices to businesses that don't comply. A café that simply hasn't bothered to put its 5 in the window can be fined for it, which feels harsh until you remember the whole point is that customers shouldn't have to go digging to find out who's clean.
One quirk worth knowing: the duty sits with businesses that deal directly with the public — restaurants, takeaways, shops, the places you actually visit. A food factory that only supplies wholesalers isn't display-bound in the same way, because no walk-in customer is ever going to see its door.
Northern Ireland: mandatory too
Northern Ireland followed Wales and made display compulsory under its own legislation. The principle is the same. Show your rating, keep it current, don't fake it. Local district councils handle enforcement and can penalise businesses that don't play along.
If you're moving between Belfast and, say, Liverpool, this is the gotcha. The same chain restaurant might legally have to show its rating in one city and be free to hide it in the other. Same brand, same food, different rulebook.
England: voluntary, and what that really means
Here's where people get the wrong end of the stick. In England a business is under no legal obligation to display its food hygiene sticker at all. The FSA encourages it, retailers' bodies encourage it, and a strong rating is genuinely good for trade — a 5 in the window is free advertising. But a business with no sticker isn't breaking any law.
This matters because a missing sticker tells you almost nothing on its own. A spotless deli with a hard-won 5 might just have lost its sticker, or never put one up, or be run by someone who finds the whole thing a bit naff. Meanwhile a place with a low rating has every incentive to keep the sticker out of sight, and in England it's perfectly entitled to.
So don't read too much into an empty window. A scenario worth picturing: you're choosing between two sandwich shops on the same street. One proudly shows a 4. The other shows nothing. Your gut says go with the 4 — but the second shop might actually be a 5 that hasn't got round to displaying. The honest answer is you can't tell by looking, which is exactly why the public register exists. Check both on the ratings directory and decide on facts, not on who had stickier sticky-tape.
There's been talk for years about making display mandatory in England to match Wales. It keeps coming up. As things stand, though, it hasn't happened, so voluntary it remains.
Scotland: a different scheme entirely
Scotland doesn't use the 0-to-5 number that the rest of the UK does. It runs the Food Hygiene Information Scheme, which gives a business one of two results: Pass, or Improvement Required. That's it. No sliding scale.
Display of the Pass certificate is voluntary. A business that's cleared the bar can show it if it likes, but isn't compelled to. And because the wording is different, a Scottish certificate sitting in a window won't look like the green-and-black sticker you'd see in Cardiff or Carlisle — don't expect a number on it.
If you're used to the star-style ratings and you cross the border, this trips you up. "Improvement Required" sounds alarming but really means the inspector found things that need fixing rather than anything that necessarily made the food dangerous on the day. Our glossary spells out the difference between the two schemes if you want the detail.
The one rule that's universal: no fakes
Across the whole UK, displaying a false rating is an offence. A takeaway that scored a 2 and prints itself a shiny 5 to stick on the door has broken the law, full stop, regardless of nation. This is the one place where England's "voluntary" stops being permissive — you don't have to show anything, but if you do show something, it has to be true.
People occasionally spot this in the wild. A sticker that looks slightly off, a number that doesn't match the place's reputation, a laminated home-made-looking thing rather than the proper FSA design. If you suspect a rating's been faked, that's worth flagging to the local authority — our guide on how to report a food business walks through it.
What you should actually do
The honest takeaway is that the window sticker is a convenience, not a guarantee, and outside Wales and Northern Ireland you can't count on it being there. So treat the public record as your real source.
You can look up any food business by name, town or postcode here, or on the FSA's own ratings.food.gov.uk. Either way you'll see the official rating, the date the inspection happened, and — for the English-style scheme — the breakdown behind the score. That breakdown is the bit a sticker can never give you. A flat number of 3 hides whether the problem was grubby surfaces or sloppy paperwork, and those are very different things to a customer.
A few practical habits that save you grief:
- Check the date alongside the rating. A 5 from four years ago is reassuring but old; standards drift, staff change, kitchens get tired. A recent inspection tells you more.
- Don't panic over a missing sticker in England or Scotland. Look it up instead of guessing.
- If a sticker and the online record disagree, the online record wins. The data held by the local authority is the authoritative version; the sticker is just a copy of it that may be out of date or, occasionally, wrong.
The numbers also reward a bit of context. Plenty of perfectly good businesses sit at 4 rather than 5 because of a single fixable issue — a missing temperature log, a fridge a degree too warm on the day. A 4 is not a warning sign. If you want a sense of what's normal in your area, the statistics page shows how ratings are distributed, and you'll see that most places cluster near the top.
A quick worked example
Say you're organising a buffet for a kid's birthday and you're picking a caterer in Newport. Wales, so by law any premises you visit should be showing its rating. If one of them isn't — no sticker anywhere — that's a small red flag, because in Wales they're supposed to. You'd be within your rights to ask to see it, and a confident, clean business will happily produce a 5.
Now run the same job in Bristol. England. None of the caterers are obliged to show anything, so an absent sticker means nothing at all. Here you'd skip the window entirely and go straight to the ratings directory, pull up each one, and compare. Same decision, completely different method, purely because of which side of the Severn you're on.
That's the whole thing in a nutshell. The sticker is helpful where it's compulsory and unreliable as a signal where it isn't — and the register behind it is the same trustworthy source no matter where you are. Use it, and the question of whether a particular café could be bothered to put a sticker up stops mattering very much.
If you'd rather browse than search, the map and near me tools let you see ratings for everywhere around you at a glance, which is handy when you're standing on an unfamiliar high street trying to decide where lunch is coming from.
