Dietary Requirements Guide for Event Caterers

Managing dietary requirements is a non-negotiable part of professional event catering. It's not a nice-to-have — it's a legal obligation and, for guests with serious allergies, potentially a matter of life and death.

This guide covers the practical steps every UK caterer should follow: the legal requirements, how to collect information effectively, kitchen protocols for safe preparation, and how to manage service on the day.

UK Allergen Law: What You Must Know

Under UK food law (retained EU Regulation 1169/2011 and the Food Information Regulations 2014), caterers must provide allergen information for all food they serve. This applies whether you're serving a plated dinner, a buffet, or canapés at a drinks reception.

The 14 major allergens

You must be able to declare the presence of these 14 allergens in every dish:

1. Celery (including celeriac)
2. Cereals containing gluten (wheat, rye, barley, oats)
3. Crustaceans (prawns, crab, lobster)
4. Eggs
5. Fish
6. Lupin
7. Milk (including lactose)
8. Molluscs (mussels, oysters, squid)
9. Mustard
10. Tree nuts (almonds, hazelnuts, walnuts, cashews, pecans, Brazil nuts, pistachios, macadamia)
11. Peanuts
12. Sesame
13. Soybeans
14. Sulphur dioxide and sulphites (at concentrations above 10mg/kg or 10mg/litre)

Your legal obligations

• Know your ingredients — you must be able to identify which allergens are in every dish, including sauces, dressings, garnishes, and marinades
• Provide information on request — for plated service, your staff must be able to tell guests about allergens. For buffets, written information must be displayed
• Keep records — maintain allergen matrices for your menus and recipes
• Train your staff — everyone handling or serving food must understand allergen risks
• Natasha's Law (October 2021) — applies to pre-packed for direct sale food (relevant if you sell boxed lunches, grab-and-go items, or pre-wrapped foods at events)

Failure to comply can result in enforcement action from your local authority, and in the worst case, criminal prosecution if a guest suffers harm.

Step 1: Collect Requirements at Booking

Don't wait until the last minute. Build dietary information collection into your booking process from day one.

Booking form template

Include these fields on your booking form or client questionnaire:

• Total guest count
• Number of vegetarian guests
• Number of vegan guests
• Guests requiring gluten-free meals
• Guests with nut allergies (specify which nuts)
• Guests with other specific allergies (free text field)
• Guests requiring halal meals
• Guests requiring kosher meals
• Any other dietary needs or preferences
• Deadline for final dietary information (state this clearly — typically 14 days before)

Best practices for collection

• Make it the client's responsibility to collect and provide dietary information from their guests — put this in your contract
• Provide a guest dietary form they can distribute — make it easy for them
• Chase at the 3-week mark if you haven't received final information
• Get specifics — "nut allergy" isn't enough. Which nuts? How severe? Is it airborne or contact/ingestion only?
• Confirm in writing — email back the dietary summary for the client to verify before you plan the menu

Step 2: Plan Menus for All Groups

Good dietary menu planning isn't about making sad alternatives. It's about designing dishes that genuinely work for every guest.

Menu planning principles

• Design dietary dishes as dishes in their own right — not as afterthoughts. A "vegan option" that's just the main course minus the meat is lazy and obvious
• Build from the bottom up — start with a naturally vegan or plant-based dish and add animal products for the standard version where needed
• Use naturally free-from ingredients — a risotto can be naturally gluten-free and dairy-free (use olive oil, vegetable stock). That's cleaner than adapting a wheat-based dish
• Cross-utilise where possible — if your starter is naturally vegan and gluten-free, that covers multiple groups with one dish and simplifies service
• Plan for the unknowns — always prepare 2–3 extra dietary meals. There's always a guest whose requirements weren't communicated

Catering for specific groups

Vegan: No animal products whatsoever — check stocks, sauces (Worcestershire contains anchovies), wines (some are fined with egg or milk), butter, cream, honey.

Gluten-free: Avoid wheat, rye, barley, and standard oats. Check soy sauce (contains wheat — use tamari), stock cubes, thickeners, breadcrumbs, and dusting flour. Use certified GF alternatives.

Halal: Meat must be halal-certified. Source from a certified halal supplier and keep certification documentation. No alcohol in cooking (including wine reductions and vanilla extract containing alcohol).

Kosher: If strictly required, this typically needs a kosher-certified caterer or kitchen. At minimum: no mixing of meat and dairy, no pork or shellfish, kosher-certified meat. Discuss the level of observance with the client.

Nut allergies: This is the highest-risk category. Remove nuts entirely from the menu where possible. If any dish contains nuts, strict separation in prep and clear labelling is essential. For severe allergies, consider whether a nut-free kitchen is necessary for the event.

Step 3: Prepare Safely — Cross-Contamination Prevention

Cross-contamination is the biggest risk in event catering kitchens, especially when you're preparing multiple dietary variants simultaneously.

Kitchen protocols

• Prepare allergen-free dishes first — before allergens are open in the kitchen
• Use separate, clearly labelled equipment — chopping boards, knives, pans, utensils. Colour-coding works well
• Separate storage — keep allergen-free ingredients away from standard ingredients. Use sealed, labelled containers
• Clean down between tasks — if you prepare a nut dish then a nut-free dish on the same surface, cleaning alone isn't sufficient. Use dedicated surfaces or prepare in sequence with full clean-down
• Check every ingredient — read labels on every delivery. Suppliers change recipes. A stock cube that was gluten-free last month might not be today
• Cover and label dietary dishes — cling film with a clear label: "VEGAN", "GF", "NUT-FREE". Never rely on memory
• Separate serving utensils — a shared spoon between a standard and a nut-free dish defeats the purpose

Staff training requirements

Every member of your kitchen and FOH team should:

• Know the 14 major allergens
• Understand cross-contamination risks and prevention
• Know the allergen content of every dish on that event's menu
• Know what to do if a guest reports an allergic reaction (call 999, check for auto-injector, preserve food samples)

Document your training. Environmental health officers will ask for records during inspections.

Step 4: Label and Serve Clearly

How you communicate allergen information during service depends on the service style.

Plated service

• Table plan with dietary flags — mark which guests at which tables have dietary requirements
• Plate identification — use a discreet marker (a specific garnish, a coloured cocktail stick, or a small flag) to distinguish dietary plates from standard ones
• FOH supervisor briefing — the supervisor should have a list of dietary guests by name and table number
• Verbal confirmation — when serving a dietary dish, the waiter should confirm with the guest: "This is the gluten-free main course — is that correct for you?"
• Never leave it to the guest to flag — your team should know who needs what before they sit down

Buffet service

• Clear labelling on every dish — dish name plus allergen information (at minimum, list which of the 14 allergens it contains)
• Separate serving utensils — one per dish, no sharing
• Position allergen-free dishes away from their allergen counterparts — don't put the nut-free salad next to the walnut-topped one
• Station a staff member at the buffet who can answer allergen questions
• Provide an allergen matrix — a printed sheet listing all dishes and their allergen content. Keep one at the buffet and one with the FOH supervisor

Canapé service

• Brief every waiter on which canapés contain which allergens
• Use separate trays for allergen-free canapés — never mix standard and free-from on the same tray
• Waiters should announce each canapé when offering it: "This is smoked salmon on rye — contains fish and gluten. Would you like one?"
• Have a designated allergen-free option that's safe for the broadest range of dietary needs

Step 5: Document Everything

Documentation protects you legally and operationally.

What to document

• Allergen matrices for every menu (which dishes contain which allergens)
• Client dietary correspondence — keep all emails confirming dietary requirements
• Supplier certifications — halal certificates, organic certifications, allergen declarations from suppliers
• Ingredient labels — keep labels from key ingredients for each event (especially for high-risk items)
• Staff training records — who was trained, when, on what
• Incident reports — if any allergen incident occurs, document everything immediately: what happened, what the guest ate, what action was taken, who was involved
• Temperature logs — food safety documentation for each event

Record retention

Keep allergen documentation and event records for a minimum of 12 months after each event. Keep training records, insurance documents, and incident reports for at least 3 years. Your local authority environmental health team may request these during routine inspections.

Building Your Reputation for Dietary Excellence

Caterers who handle dietary requirements well earn referrals. Guests with allergies remember the caterer who made them feel included rather than difficult. That reputation spreads.

Showcase your dietary capabilities in your marketing — mention your allergen training, your approach to inclusive menus, and your kitchen protocols. When listing on platforms like FolkAir, highlight your experience with dietary-inclusive catering. It's a genuine differentiator.
