UK Coffee Chain Hygiene Ratings Ranked: Starbucks, Costa, Pret, and Caffe Nero Compared
8 min read
We ranked the UK's four biggest coffee chains by food hygiene rating using FHRS data across 2,982 inspected locations. Starbucks leads at 97.5% five-star. Caffe Nero trails at 70.7%. The gap is 27 percentage points, and the data reveals where and why.
TLDR
- Starbucks has the highest five-star rate among major UK coffee chains at 97.5% across 651 locations.
- Pret A Manger follows at 93.7% across 394 locations, with zero outlets rated 0, 1, 2, or 3.
- Costa Coffee scores 91.6% five-star across 1,432 locations. Only 4 outlets are rated 2 or below.
- Caffe Nero sits at 70.7% five-star across 505 locations. 114 branches are rated 4, and 34 are rated 3 or below.
- The gap between the best and worst performer is 27 percentage points on five-star rate.
- Smaller chains Coffee #1 (93.0%) and Black Sheep Coffee (90.2%) outperform Caffe Nero despite having a fraction of the locations.
- Every chain mentioned links to its live guide page with individual location breakdowns.
The UK's high street coffee market is dominated by four brands: Costa Coffee, Starbucks, Pret A Manger, and Caffe Nero. Together they operate nearly 3,000 inspected locations across England, Wales, and Northern Ireland.
All four are national brands with standardised menus, central training programmes, and corporate food safety teams. You would expect their food hygiene ratings to be similar. They are not.
We analysed FHRS data for all four chains across our database of 604,356 UK food establishments. The results show a 27 percentage point gap in five-star rates between the best and worst performer. That gap is wider than the difference between some of the best and worst performing postcodes in the country.
This is not a review of coffee quality. It is a data-led comparison of what food safety inspectors found when they walked into these premises. Every number below comes from official FHRS inspection records, cross-referenced in our database.

The rankings: how each chain performs
Here is how the four major UK coffee chains compare on food hygiene ratings, ranked by percentage of locations rated 5:
| Chain | Locations | Avg Rating | % Rated 5 | % Rated 4 | % Rated 3 or Below |
|---|---|---|---|---|---|
| Starbucks | 651 | 5.0 | 97.5% | 2.2% | 0.3% |
| Pret A Manger | 394 | 4.9 | 93.7% | 6.3% | 0.0% |
| Costa Coffee | 1,432 | 4.9 | 91.6% | 7.4% | 1.0% |
| Caffe Nero | 505 | 4.6 | 70.7% | 22.6% | 6.7% |
Starbucks leads with 97.5% of its 651 inspected UK locations holding a five-star rating. Only 2 locations across the entire estate are rated below 4. Pret A Manger is close behind at 93.7%, and notably has zero locations rated 3 or below. Every Pret branch in the country is rated either 4 or 5.
Costa Coffee, the largest chain by location count at 1,432 premises, scores 91.6% five-star. Its scale means even a small percentage of lower ratings translates to meaningful numbers: 14 Costa locations are rated 3 or below, including 2 rated at 2.
Caffe Nero is the outlier. At 70.7% five-star across 505 locations, it trails Starbucks by 27 percentage points. 114 Caffe Nero branches are rated 4. Another 21 are rated 3. Two are rated 2. Two more are rated 1. That gives Caffe Nero 34 locations rated 3 or below, representing 6.7% of its estate.
Why is Caffe Nero's gap so large?
A 27 percentage point gap between competitors operating in the same market with similar menus demands explanation. Three factors likely contribute.
First, the concentration of rating-4 locations. Caffe Nero has 114 branches rated 4. That is 22.6% of its estate. For comparison, Starbucks has 14 locations rated 4 (2.2%) and Pret has 25 (6.3%). A rating of 4 means 'good' and it is not a food safety concern. But the volume suggests a systemic pattern where Caffe Nero locations are consistently losing marks on one or more inspection criteria.
Second, the confidence in management sub-score. Our previous analysis showed that this sub-score is the most common reason businesses get capped at 4 instead of 5. It measures documentation quality, training evidence, and the inspector's assessment of whether the food safety management system is genuinely embedded. A chain with a high proportion of 4s is likely losing marks here rather than on structural or hygiene grounds.
Third, operational model differences. Caffe Nero locations tend to offer more extensive food preparation (paninis, pastries heated on-site, fresh food assembly) compared to a typical Starbucks outlet. More food handling steps means more inspection points. But Pret A Manger arguably has even more complex food preparation and still achieves 93.7% five-star, which suggests the gap is not fully explained by menu complexity.
How smaller coffee chains compare
The four major chains are not the only coffee brands in our database. Here is how three smaller chains perform:
| Chain | Locations | Avg Rating | % Rated 5 |
|---|---|---|---|
| Coffee #1 | 115 | 4.9 | 93.0% |
| Black Sheep Coffee | 82 | 4.9 | 90.2% |
| Esquires Coffee | 44 | 4.6 | 72.7% |
Coffee #1, with 115 locations primarily in Wales and the South West, matches Pret's five-star rate. Black Sheep Coffee, a rapidly expanding London-based chain with 82 locations, sits at 90.2%. Both outperform Caffe Nero despite operating at a fraction of the scale.
Esquires Coffee (44 locations) is the only smaller chain that sits in Caffe Nero's territory at 72.7% five-star. Four of its 44 locations are rated 3, and one is rated 2.
Scale alone does not explain performance. Costa operates nearly three times as many locations as Caffe Nero and still achieves a 21 percentage point higher five-star rate. The operational systems behind the rating matter more than the number of premises.
Coffee chains vs fast food: where do they sit?
For context, here is how the coffee chains compare to the largest fast food brands in our database:
| Chain | Locations | % Rated 5 |
|---|---|---|
| Domino's Pizza | 1,119 | 99.0% |
| Nando's | 379 | 98.9% |
| Starbucks | 651 | 97.5% |
| McDonald's | 887 | 97.3% |
| Greggs | 1,503 | 96.6% |
| KFC | 664 | 94.3% |
| Pret A Manger | 394 | 93.7% |
| Burger King | 411 | 92.9% |
| Costa Coffee | 1,432 | 91.6% |
| Caffe Nero | 505 | 70.7% |
Domino's Pizza tops the table at 99.0% five-star across 1,119 locations. Only 11 Domino's outlets in the entire UK are not rated 5. Nando's and McDonald's both sit above 97%.
Caffe Nero is the only major chain in this comparison that falls below 80%. The next lowest, Subway at 84.7% across 1,514 locations, still outperforms Nero by 14 percentage points. For a look at what a true lower-tail outlier looks like in fast food, see our Dixy Chicken hygiene ratings analysis. For the positive counterpoint: a fried chicken chain outperforming the UK takeaway average with zero sites at 0 or 1: see the Chicken Cottage FHRS benchmark.
The pattern suggests that the best-performing chains have standardised their food safety management systems to the point where individual location variation is minimal. When 99% of a chain's outlets score 5, the system is working. When only 71% do, something in the system is producing inconsistent outcomes.
What this means for consumers
A Caffe Nero five-star rating of 70.7% does not mean 30% of its outlets are unsafe. A rating of 4 is 'good.' A rating of 3 is 'generally satisfactory.' The risk to consumers is low at any major chain location.
But ratings do reflect what an inspector found on the day. A rating below 5 means the inspector identified areas for improvement. At 2 locations rated 1 ('major improvement necessary'), the inspector found significant problems that required urgent attention.
Consumers who check ratings before choosing where to eat or buy coffee can use our chain guide pages to see the rating for any specific branch. National brand reputation is not a reliable proxy for individual location performance. The data shows that even within the same chain, ratings vary.
Delivery apps in Wales and Northern Ireland are required to display FHRS ratings. In England, display is voluntary. Until that changes, checking the rating yourself before ordering is the only way to know. Use our hygiene rating checker to look up any business in seconds.
What this means for coffee chain operators
For multi-site operators, the chain rankings data reveals where your estate sits relative to competitors. A five-star rate below 90% across 50+ locations is a signal that food safety management systems are producing inconsistent results.
The most common lever for moving from 4 to 5 is the confidence in management sub-score. This means documentation, not deep cleaning. Temperature logs that cover the full operating day. Training records that are current. SFBB or HACCP plans that reflect actual practice rather than a generic template.
Continuous temperature monitoring is the single fastest way to improve this sub-score across a multi-site estate. A system that logs every five minutes replaces the two manual checks per day that most coffee shops rely on. It generates the evidence trail that shifts inspector confidence from 'adequate' to 'well managed.'
For Caffe Nero specifically, the data suggests an opportunity. Moving 114 locations from a 4 to a 5 would shift the chain's five-star rate from 70.7% to 93.3%, putting it in line with Pret and Costa. That is a documentation and systems challenge, not a structural one.
Common mistakes
- Assuming all major coffee chains have similar food hygiene standards because they are national brands.
- Treating a rating of 4 as equivalent to a rating of 5. A 4 means the inspector found areas for improvement.
- Judging a chain by its national average without checking the specific branch you visit.
- Overlooking the confidence in management sub-score as the key differentiator between a 4 and a 5.
- Believing that smaller chains automatically have worse ratings than large ones. Coffee #1 and Black Sheep Coffee both outperform Caffe Nero.
