The UK's Cleanest and Dirtiest Areas for Food Hygiene

Food hygiene standards vary significantly across the UK. Some local authorities have over 90% of their businesses rated 4 or 5, while others fall well below the national average. We have analysed the data from over 600,000 food businesses to identify the patterns.

The Cleanest Areas

The local authorities with the highest average food hygiene ratings tend to share common characteristics: they are often smaller or rural authorities with fewer businesses to inspect, and they typically have well-resourced environmental health teams.

You can see the full up-to-date list on our Cleanest Local Authorities ranking. The top authorities consistently achieve average ratings above 4.8, with over 95% of businesses rated 4 or 5.

The Lowest-Rated Areas

Authorities at the bottom of the rankings tend to be in larger urban areas with high concentrations of food businesses, particularly takeaways and smaller restaurants. These areas often face challenges including:

• Higher turnover of food businesses, meaning less time to embed good practices
• Greater diversity of cuisine types, some with different food safety traditions
• More businesses per EHO, meaning longer gaps between inspections
• Higher proportion of small businesses with limited resources for food safety management

Regional Patterns

Looking at the data by country, some broad patterns emerge:

• England – Wide variation between authorities. Rural and suburban areas tend to perform better than large cities. London boroughs show particularly wide variation.
• Wales – Generally strong performance, partly attributed to the mandatory display requirement introduced in 2013 which incentivised businesses to maintain higher standards.
• Northern Ireland – Consistently good performance, also benefiting from mandatory display since 2016.

What Drives the Differences?

Several factors influence food hygiene standards at the local level:

1. Inspection frequency – Areas with more frequent inspections tend to have better compliance. Businesses that know they will be inspected soon are more likely to maintain standards. See authorities with the oldest inspections.
2. Mandatory display – Wales and Northern Ireland, where displaying the rating is legally required, have seen improvements since the law was introduced.
3. Business demographics – Areas with more takeaways and small restaurants relative to larger chains tend to have lower averages.
4. Local authority resources – Councils with more EHOs per business can inspect more frequently and provide more guidance.
5. Consumer awareness – In areas where consumers actively check ratings, businesses are more motivated to maintain high standards.

The Big Picture

Despite the variation, it is important to note that the vast majority of UK food businesses meet acceptable hygiene standards. Over 70% of businesses nationally hold a rating of 5 (Very Good), and fewer than 1% hold a rating of 0 or 1.

The differences between areas, while statistically significant, are relatively small in absolute terms. Even in the lowest-rated authorities, the majority of businesses still achieve a Good or Very Good rating. The data should be used not to avoid entire areas, but to make informed choices about individual businesses wherever you are.
