Allergenius · System overview
What is allergen software?
Allergen software is a digital system that helps food businesses track, manage and display allergen information for every dish they serve. It replaces paper allergen matrices, printed folders and verbal communication with a live, centralised solution that is always accurate and always accessible.
In the UK, food businesses are legally required to provide allergen information to customers. Allergen software makes meeting that obligation straightforward — and removes the everyday risks that come with manual, paper-based approaches.
Allergenius is allergen software designed specifically for UK food businesses. It covers all 14 allergens recognised under UK law, generates a live digital menu accessible via QR code, and updates in real time whenever a recipe or ingredient changes — all from a simple, no-training-required dashboard.

Everything you need from allergen software
Allergen Tracking
All 14 allergens, every dish
Assign any combination of the 14 UK allergens to each dish on your menu. Your allergen data stays consistent, centralised and current — no spreadsheets, no folders.
Live Digital Menu
QR code your guests can trust
Your allergen software generates a unique QR code linked to a live digital menu. Guests scan it on any smartphone and see every dish's allergen information instantly — no app needed.
Real-Time Updates
Change a recipe, update in seconds
Swap an ingredient, update a supplier or launch a new dish — your allergen data updates immediately. Every guest scanning your QR code sees the latest, accurate information.
Guest Allergen Filter
Let guests find what's safe for them
Your digital menu lets customers filter by their specific allergy or intolerance — instantly seeing only the dishes that are suitable for them. Far safer and clearer than asking staff.
Compliance Ready
Built around UK allergen law
Allergenius allergen software is designed with Natasha's Law and the FSA's 2025 guidance in mind — helping you meet your legal obligations without the administrative overhead.
Simple to Use
No technical knowledge needed
Add dishes, assign allergens, publish your menu. That's it. Allergenius is built for busy food businesses — not IT teams. Most venues are live within the same session.
Allergen software vs. doing it manually
Paper systems and spreadsheets can't keep pace with a real kitchen. Allergen software can.
When a recipe changes, a paper allergen sheet can't update itself. When a guest asks a staff member, the answer depends on who's on shift. Allergen software removes both problems — keeping your allergen data accurate, live and directly accessible to everyone who needs it.

Allergen software & UK food law
Food Information Regulations
Allergen information must be accessible
UK food law requires businesses to provide customers with accurate allergen information. The expectation — supported by FSA guidance — is that this information should be proactively available, not locked behind a verbal request to staff.
Natasha's Law · Oct 2021
Labelling for pre-packaged food
All food pre-packaged for direct sale must carry a full ingredient and allergen label. Allergenius allergen software helps you maintain the accurate records needed for compliance across everything you prepare and sell.
FSA Guidance · 2025
Allergens should appear on the menu
The FSA's 2025 guidance asks food businesses to display allergen information directly on the menu presented to customers. Allergenius makes this practical — with a live, guest-facing digital menu that's always accurate.
