Which type of food business has the worst hygiene ratings?

It's a fair question when you're standing outside a chip shop deciding whether to risk it: which kind of food business is statistically most likely to fall short on hygiene? We took the official 0–5 ratings published by the Food Standards Agency and ranked seven common business types by their average score. The answer is less dramatic than the headlines you might expect, and that's the interesting part.

One thing to settle before the league table. Every single type below averages comfortably above 4 out of 5. So even the "worst" performer here is, on the whole, doing well — better than four out of five would suggest at a glance. A rating reflects the standards an inspector found at the last visit: kitchen cleanliness, how food is handled, and how well the business manages safety on paper. It isn't a verdict on the taste of the food, and it's certainly not proof that any particular venue is dirty today. If you want a refresher on what the numbers actually measure, see our guide to what each rating means.

The ranking, worst to best

Here are the seven types, ordered from the lowest average rating to the highest.

• Takeaways and sandwich shops — average 4.33; 60.9% rated 5; 0.3% rated 0.
• Other retailers — average 4.51; 71.2% rated 5; 0.3% rated 0.
• Restaurants, cafes and canteens — average 4.60; 75.2% rated 5; 0.2% rated 0.
• Pubs, bars and nightclubs — average 4.66; 76.8% rated 5; 0.1% rated 0.
• Mobile caterers — average 4.82; 88.2% rated 5; 0% rated 0.
• Hospitals, childcare and caring premises — average 4.84; 88.1% rated 5; 0% rated 0.
• Schools, colleges and universities — average 4.90; 92% rated 5; 0% rated 0.

So takeaways and sandwich shops sit at the bottom with a 4.33 average, while schools, colleges and universities top the table at 4.90. The gap between best and worst is real but modest — less than six-tenths of a point. Put another way: the difference between the most-scrutinised school canteen and the average kebab shop is about half a star. That's the gap that gets written up as "takeaways are the dirtiest". The data doesn't really support the panic.

Worth sitting with that takeaway figure for a second. 60.9% rated 5 means that if you pick a takeaway or sandwich shop at random, the most likely single outcome — by a wide margin — is the top score. The category sits at the bottom of the table not because most of them are poor, but because the minority that score 1, 2 or 3 pull the average down. A handful of low scores drag the mean further than a pile of 5s can lift it. That's how averages work, and it's why a low average for a whole category rarely tells you much about the place in front of you.

Why takeaways come bottom

A low-ish average doesn't mean takeaway owners care less. Several structural things push this category down, and almost none of them are about cutting corners on purpose.

• Tight spaces and a relentless rush. Plenty of takeaways and sandwich shops run out of small premises with cramped kitchens. Less room makes it genuinely harder to keep raw and ready-to-eat foods apart, store everything where it should go, and keep busy surfaces spotless on a Friday night when there's a queue out the door. A big restaurant kitchen has a designated chopping zone for raw chicken; a one-man chicken shop might have a single prep bench doing everything.
• Paperwork, not just the cooking. A large chunk of the rating comes from "management of food safety" — written procedures, temperature records, allergen information, being able to show an inspector that you actually control your hazards rather than just hoping for the best. Smaller, owner-run businesses sometimes have excellent practices in the kitchen but thin documentation, and that alone can knock a score down even when the place is spotless. The food was fine. The folder wasn't.
• High churn of staff and ownership. Takeaways change hands often, and staff turnover is high. Training and systems can quietly lapse in the gap between one owner's careful routine and the next owner finding their feet.

That last point matters because the score is only a snapshot in time. A new owner, a tightened cleaning rota, or simply getting the Safer Food, Better Business pack filled in properly can lift a rating sharply at the next inspection. Plenty of 1s and 2s become 5s once someone sorts out the records. If you're curious how an inspector actually arrives at the number, we've broken down how inspections work.

It's also why two takeaways on the same high street can be miles apart. One scores a 5 because the owner keeps a tidy diary of fridge temperatures and labels everything; the one next door, frying identical food, sits on a 2 because the inspector couldn't see any evidence of a system. Same trade, same street, wildly different score. The category average flattens all of that into a single misleading number.

Why schools and hospitals score highest

At the top of the table, schools, hospitals and care settings get a few built-in advantages that a corner sandwich shop never will.

• They feed people who can least afford a slip-up. Children, hospital patients and elderly residents are more vulnerable to foodborne illness, as the NHS makes clear, so these kitchens tend to run especially tight systems and are inspected with that risk firmly in mind. The stakes are higher, and everyone involved knows it.
• Bigger, more professionalised catering. Many are run by dedicated catering teams or outside contractors with formal written procedures, trained staff, and regular internal audits — which is exactly the "management" side of the rating that inspectors reward. The paperwork that trips up a busy takeaway is somebody's full-time job here.
• Purpose-built kitchens. A facility designed as a catering kitchen makes proper separation, cold storage and deep cleaning far easier than a converted shopfront ever could. Space solves a lot of problems before they start.

Mobile caterers also do well, at 4.82, which surprises people who picture a grease-streaked burger van at a car boot sale. In practice, a lot of mobile caterers are recently set up, work out of purpose-fitted trailers and units, and serve a short, well-rehearsed menu. A small menu means fewer ingredients to manage, fewer cross-contamination risks, and a routine the operator can do in their sleep. Simplicity scores well.

There's a subtler point hiding in the school figure too. 92% rated 5 is high, but it's not 100% — even the best-performing category in the country has roughly one in twelve premises sitting below the top mark. No type is a guarantee. That cuts both ways: a low-ranked category contains thousands of immaculate kitchens, and the top-ranked one still has rooms for improvement.

A worked example: same hunger, two choices

Say it's lunchtime and you've got two options near the office. A sandwich shop from the bottom-ranked category, and a cafe from the restaurants group sitting mid-table at 4.60. The instinct is to trust the cafe because "restaurants score better". But the category average is the wrong tool for choosing between two named premises. The sandwich shop might be one of the 60.9% holding a 5; the cafe might be one of the minority that don't.

The only way to know is to look up the two actual businesses and compare the real ratings, not the category they belong to. That's a thirty-second job. If they're genuinely close, you can compare them side by side and check when each was last inspected — a 5 from last month is worth more confidence than a 5 from three years ago, though both are valid until the next visit.

How to read this fairly

The honest headline is that type is a weak predictor for any individual venue. With 60.9% of takeaways already rated 5, the category average is dragged down by a minority, not the majority — and judging a specific shop by its category is exactly the mistake the data warns against. A few sensible moves:

• Look up the exact venue before you order or visit, then check the date of its last inspection so you know how current the number is.
• Use our statistics page to see the wider picture across the UK rather than relying on one figure.
• Read what the 0–5 scale actually measures, so a single number doesn't get taken out of context.
• Remember that high counts of low-rated businesses often just track population and density — a big city has more food outlets, so it has more of everything, including the few that score poorly.

That last point is worth holding onto when you see a scary-looking local statistic. A borough with "hundreds of businesses below 5" probably just has thousands of food businesses full stop. Raw counts follow population; rates are what you want to compare. If you're poking around your own area, the area pages break the picture down by local authority so you're comparing like with like.

And if you ever walk into somewhere and see conditions that genuinely worry you — not just a quiet kitchen, but visible filth, pests, or food being handled badly — you don't have to rely on the published rating at all. Here's how to report a food business to your local council, who can send an inspector to take a fresh look.

One last reminder, and it's the important one. HygieneCheck is an independent directory built on FSA open data; we're not affiliated with the Food Standards Agency. Ratings change every time a business is re-inspected, so the score you see today might not be the score next month — for better or worse, and often for the better once a struggling kitchen sorts itself out. Use the category averages to understand the landscape. Use the individual rating to make your decision.
