Managing allergen compliance in a single restaurant is challenging enough. Across multiple sites with different kitchen teams, different supplier relationships, and dishes that vary slightly between locations, it becomes exponentially more complex.
Yet the legal requirement is the same regardless of scale. Every food business in the UK must be able to provide accurate allergen information to customers on request. And under Natasha’s Law any food pre-packaged on site for direct sale must carry full ingredient and allergen labelling.
Where multi-site operators get into trouble the most common failure point for multi-site operators is inconsistency. A dish may be nominally the same across all sites but small variations in ingredients mean the allergen profile differs between sites. When a customer with a nut allergy asks whether a dish is safe the answer may be different depending on which site they are in.
Building a consistent allergen management framework the solution is to centralise your recipe and allergen data while allowing for controlled site-level variations. This means maintaining a master recipe database that every site works from with a clear process for recording and approving any site-specific substitutions.
Every substitution needs to be assessed for allergen impact before it is approved. If a site wants to use a different supplier for an ingredient that supplier’s allergen declarations need to be checked against the original supplier’s before the substitution is permitted.
Staff training is part of the system.
technology solves the data problem but it does not solve the human problem. Allergen management in a hospitality environment depends on staff at every level understanding their role from the chef who checks ingredient labels to the front-of-house team member who handles customer allergen queries.
Practical steps for multi-site operators
Centralise all recipe and allergen data in a single system accessible to all sites. Establish a formal process for approving site-level ingredient substitutions. Require allergen declarations from all suppliers before approving them for use. Train all staff on allergen awareness. Conduct regular allergen audits across all sites.
