The Chain Advantage
It is a common comfort that the local independent cooks with more care than the corporate chain. The UK Food Standards Agency's hygiene rating register, all 605,000 establishments of it, says it is the other way around. Mega-chain sites top-rate at 89%. Independents at 78%. And the pattern is monotonic across the spectrum.

The Food Hygiene Rating Scheme covers most food premises that sell or supply food in the UK. Inspectors rate three areas (hygienic food handling, cleanliness and condition of the premises, confidence in management) and combine them into a single 0-to-5 score. We took the full FSA register, grouped premises by normalised business name to identify chains, and asked a simple question: does chain size predict hygiene?
We did not expect the answer to be quite so clean. As chain size goes up, the share of sites holding the top rating goes up too, monotonically, with no exception.
| Chain size | Sites rated | Mean rating | % top-rated | % poor (0-2) |
|---|---|---|---|---|
| Independent (1 site) | 335,876 | 4.65 | 78.0% | 3.1% |
| Mini (2-4 sites) | 56,433 | 4.58 | 74.1% | 3.6% |
| Small chain (5-9) | 19,459 | 4.58 | 74.3% | 3.6% |
| Mid chain (10-49) | 30,826 | 4.62 | 75.9% | 3.1% |
| Big chain (50-199) | 15,244 | 4.75 | 84.1% | 2.1% |
| Mega chain (200+) | 24,688 | 4.85 | 89.3% | 1.0% |
Eight chains have a clean sweep
Among chains with 50 or more rated sites, eight have a 100% top-rated record across every one of their premises in the FSA register: Five Guys (161 sites), Marks & Spencer (71), itsu (68), Waitrose (64), Boots (57), Giggling Squid (51), Admiral Casino (52), and the M&S Simply Food sub-brand (64). Several others come within a hair: Domino's Pizza (990 sites, 99.0% top-rated), Sushi Daily, Boots UK Ltd, and Nando's all sit above 99%.
| Chain | Sites rated | Mean | % top-rated |
|---|---|---|---|
| Five Guys | 161 | 5.00 | 100.0% |
| Marks & Spencer | 71 | 5.00 | 100.0% |
| itsu | 68 | 5.00 | 100.0% |
| Waitrose | 64 | 5.00 | 100.0% |
| Boots the Chemist | 57 | 5.00 | 100.0% |
| Giggling Squid | 51 | 5.00 | 100.0% |
| Domino's Pizza | 990 | 4.99 | 99.0% |
| Nando's | 275 | 4.99 | 98.9% |
| Starbucks | 645 | 4.98 | 98.0% |
| Aldi | 467 | 4.98 | 98.7% |
| McDonald's | 566 | 4.97 | 97.3% |
| Greggs | 1,505 | 4.96 | 96.5% |
And not all chains are equal
The chain advantage is not a corporate-everywhere result. Drop into the bottom of the 50-plus-site table and the pattern flips: a cluster of franchised convenience-store brands (Go Local, Family Shopper, Best One, Premier, Costcutter, Londis) sit between 4.0 and 4.3 on the same scale, with 6 to 14% of their sites rated 0, 1 or 2 for hygiene. The lowest-rated 50-plus-site chain in the FSA register is Dixy Chicken, with a mean of 3.77 and nearly one in five sites in the bottom three bands.
What separates the two groups is structure, not size. The top chains are corporate-owned or tightly-controlled franchise operations with central training, internal audits and a national brand to protect. The bottom group is dominated by loose franchise badges over independent stores, where the "chain" is a buying group and the local operator carries the practice. The advantage of size only kicks in when standardisation comes with it.
| Chain | Sites rated | Mean | % rated 0-2 |
|---|---|---|---|
| Dixy Chicken | 92 | 3.77 | 19.6% |
| Golden Dragon | 89 | 3.93 | 9.0% |
| Go Local | 192 | 4.00 | 13.5% |
| Family Shopper | 99 | 4.05 | 12.1% |
| Go Local Extra | 96 | 4.06 | 12.5% |
| Lucky House | 64 | 4.13 | 0.0% |
| Costcutter | 351 | 4.15 | 6.0% |
| Best One | 242 | 4.16 | 8.7% |
| Premier | 268 | 4.18 | 7.8% |
| China Garden | 81 | 4.19 | 4.9% |
| Londis | 480 | 4.28 | 5.6% |
| Caffè Nero | 520 | 4.60 | 3.3% |
What this isn't saying
It is not that every chain restaurant is better than every independent. 78% of independents in the register hold the top rating, which is most of them. The point is distributional, not personal: the share of independents that fall short of 5/5 is larger than the share of mega-chain sites that do. If you walk in to a random McDonald's, Greggs or Tesco branch you are more likely to find top-rated hygiene than if you walk in to a random independent.
It is also not the whole story of food quality. Hygiene ratings are about food handling and premises, not flavour, sourcing, ethics or anything else you might care about. Plenty of 4-rated independents will be cooking food a corporate kitchen could not match. But on the narrow question the FSA inspector is paid to answer, the chains win.
Methodology
Source: the UK Food Standards Agency's Food Hygiene Rating Scheme (FHRS) register for England and Wales (Northern Ireland follows the same scheme; Scotland is on a different Pass/Improvement Required scheme and is excluded from this analysis). We took every premise with a numeric rating of 0 to 5 (482,526 sites in our snapshot) and grouped premises into chains by lower-casing and stripping punctuation from the business name.
Buckets are by count of premises sharing the same normalised name: 1 (independent), 2-4 (mini), 5-9 (small chain), 10-49 (mid chain), 50-199 (big chain) and 200 or more (mega chain). The leaderboards restrict to chains with at least 50 rated sites so a handful of premises can't dominate the ranking. The normalisation is intentionally simple, which preserves cross-chain separation but does not merge name variants within a single chain (e.g. Tesco, Tesco Express and Tesco Extra are counted as separate chains). FSA data is published under the Open Government Licence.
Check any of these for yourself: browse every chain, look up your local authority, or search a specific restaurant.
