Food Hygiene Rating Scheme: What the Score on the Door Actually Means
How ratings from 0 to 5 are worked out, what a 3 really tells you, and why display rules differ across the UK.
The green and black sticker is one of the more successful pieces of public information in British life. Most people can tell you that 5 is good and 1 is bad. Rather fewer know what the number is measuring, how often it is refreshed, or why a well-regarded restaurant might be carrying a 3.
It is worth understanding, because the rating is more informative than it first appears and also more limited. It is a snapshot of an inspection, not a running assessment, and it says nothing whatsoever about whether the food is any good.
Where the Scheme Comes From
The scheme is run by the Food Standards Agency in partnership with local authorities. Ratings are published on the FSA ratings site, which is free to search and covers the whole UK, and the underlying inspections are carried out under food hygiene law.
Three Things Are Assessed

Officers score three separate elements: how hygienically the food is handled, the physical condition of the premises, and how well the business manages and records what it does. Each is scored, and the combined result is converted into the 0 to 5 rating.
The Management Element Surprises People
A kitchen can be spotless and still lose marks for having no written procedures, no records and no evidence of training. Because the three elements combine, weak paperwork alone can pull an otherwise good business down to a 3.
What Each Number Means
Five is very good, four good, three generally satisfactory, two improvement necessary, one major improvement necessary and zero urgent improvement necessary. The wording matters: a 3 is a pass, not a warning, though it does indicate that something was found.
Display Rules Differ Across the UK
In Wales and Northern Ireland, displaying the rating is a legal requirement with penalties for failing to do so. In England it remains voluntary, which is why an English business with a low score may simply not put the sticker up. The rating is still published online.
How Often Businesses Are Inspected
Frequency is risk-based. A high-risk business with a poor history is inspected far more often than a low-risk one with a strong record, and intervals can run to years at the low-risk end. A 5 from three years ago is a weaker signal than a 5 from last month.
Check the Inspection Date
The date is published alongside the rating and is the piece most people ignore. A business that has changed hands since its last inspection is effectively unrated, since the score attaches to the premises and the previous operation.
Requesting a Re-Rating
A business that has fixed the problems can request a re-inspection, usually after a set period and sometimes for a fee. This is the route back from a poor score, and it is why a low rating is not permanent.
Appeals and the Right to Reply
There is an appeals process where a business believes the rating is wrong, with a defined time limit. Separately, businesses can publish a short right to reply alongside their rating explaining what has since changed. Both appear through the local authority.
What the Rating Does Not Tell You
It says nothing about food quality, value, service or sourcing. A 5 tells you the kitchen was run properly on the day it was seen. Whether you will enjoy what arrives is a different question entirely, and one that a pub menu answers rather better.
Takeaways and Delivery Platforms
Delivery apps increasingly display ratings, and coverage varies. Where a rating is absent from an app it is worth searching the official site directly, particularly for dark kitchens operating several brands from one address.
One Address, Several Brands
Virtual brands frequently share a single kitchen and therefore a single rating. If four listings on an app all show the same score and the same postcode, that is generally what is happening, and it is legitimate.
Mobile and Market Traders

Vans, stalls and pop-ups are rated in the same way, with the rating attached to the operator rather than the pitch. Many display it on the van; the online search works by business name where they do not.
Schools, Care Homes and Hospitals
Institutional caterers are covered by the scheme too, and their ratings are searchable. For settings where texture-modified meals are prepared, hygiene sits alongside the separate question of whether food is being made to the right consistency under the IDDSI framework.
What Actually Causes Low Scores
In practice: pest activity, inadequate handwashing facilities, poor structural condition, raw and ready-to-eat food handled together, no temperature records and no documented system. Very few low ratings arise from a single unlucky finding.
Ratings Follow the Premises, Not the Chef
A change of management, a refurbishment or a new head chef does not alter the published score until the next inspection or a requested re-rating. This is the most common reason a genuinely improved business still shows an old, poor number.
Complaints Can Trigger a Visit
Local authorities investigate complaints about food premises and may inspect outside the normal cycle. Reports from the public are one of the routes by which problems between scheduled inspections come to light.
How the Score Is Calculated
Each element is scored on a scale where lower is better, the three are added, and a business must also not exceed a maximum in any single element. This is why one very poor area caps the overall rating regardless of the others, a mechanism that follows from the inspection framework in the Food Safety and Hygiene (England) Regulations 2013.
Using It Sensibly
Treat 5 and 4 as reassurance, 3 as adequate with something to note, and 2 or below as a reason to look at the date and at whether a re-inspection has happened. Then check the date before drawing any conclusion at all.
This is a general explanation, not legal advice. Food law changes, enforcement is carried out locally, and the requirements that apply to a particular business depend on what it does. Anyone running a food business should check current guidance and speak to their local authority environmental health team rather than rely on a summary.
