Navigating City of London (The Square Mile) EHO inspections with confidence
Independent food safety and HACCP support for City of London (The Square Mile) food businesses — built around the Food Hygiene Rating Scheme (FHRS) and how City of London Corporation Environmental Health actually inspects.
How food hygiene inspections work in London
London boroughs run some of the busiest Environmental Health teams in the country, and inspections are unannounced. High customer turnover, dense kitchens and heavy reliance on delivery platforms mean a single slipped control can show up quickly on your public FHRS score.
We build your HACCP, allergen controls and inspection readiness around how your specific borough team actually works — so the rating on your door reflects the kitchen you run on a normal Tuesday, not just on inspection day.
The City of London Corporation Environmental Health oversees one of the most commercially pressured square miles in the country — corporate contract caterers, fine dining venues, luxury cocktail bars and rooftop event spaces all running peak covers under intense scrutiny. High staff turnover, demanding client contracts and the concentration of premium operations mean allergen documentation and temperature controls need to hold under real pressure every service.
The rating scheme
City of London (The Square Mile) is assessed under the Food Hygiene Rating Scheme (FHRS) — a 0–5 score, where 5 is "very good" and anything below 4 sits beneath the threshold most diners look for. Your score is published on the FSA's public register at ratings.food.gov.uk as soon as the inspection is signed off.
Displaying your result
Displaying your sticker is voluntary in England, but Deliveroo, Uber Eats and Just Eat now surface FHRS scores in their apps, and most London diners check a rating before they book.
The legal standard
Compliance in City of London (The Square Mile) is set by the Food Safety Act 1990 and assimilated Regulation (EC) 852/2004, enforced by your London borough's Environmental Health team.

Inspection-ready
Flagged at inspectionHow this plays out in City of London (The Square Mile)
A corporate contract caterer in the Square Mile came to us when its food safety management system had grown out of step with its actual operation — records that looked complete on paper but did not reflect how the kitchen ran day to day. We reviewed the existing HACCP plan against the live menu and service pattern, rebuilt the documentation from the ground up and retrained the team so the system was genuinely embedded rather than filed away for inspections.
This scenario is a composite based on typical engagements Kitchen Tonic handles for UK food businesses — not a specific named client.
