Managing dietary requirements at corporate events is one of the most practically complex elements of event planning — and the one most likely to cause problems if not handled systematically. This guide covers the process from data collection through to event-day execution, with specific attention to the requirements that matter most for London's diverse corporate event guest lists.
Step 1: Collect Requirements Early and Completely
Dietary requirement data collection needs to happen as early as possible — ideally at the point of event invitation, not as a separate follow-up. The longer the gap between invitation and data collection, the lower the response rate and the more likely you are to be chasing information the day before the event.
What to ask: any halal or kosher requirement; any vegetarian or vegan preference; any allergy covering the 14 mandatory UK allergens (particularly peanut, tree nut, gluten, dairy, eggs, sesame); any other significant dietary restriction. Use a standardised form or registration question — open text fields produce varied and sometimes ambiguous responses that require follow-up. Pre-defined categories with an "other" option produce cleaner data.
Step 2: Brief Your Caterer With Complete Data
Share the complete dietary summary with your caterer at least five working days before the event (longer for larger events). Include not just the numbers — "three halal, two nut-free, one coeliac" — but the format: is the nut-free requirement a preference or a severe allergy? Is the halal requirement from observant guests or a general preference? This context helps your caterer manage the requirements appropriately.
For events where some dietary requirements are not known in advance (guest lists that include clients or external guests), choose a caterer whose baseline output is already safe for the most common requirements. Vanda's Kitchen's certified halal, 100% nut-free kitchen means that every item served is safe for Muslim guests and guests with nut allergies without any special ordering. The unknown becomes manageable when the default is already inclusive. Read our allergy-friendly catering guide.
Step 3: Choose the Right Serving Format
For events where dietary requirements are diverse or where guest dietary information is incomplete, individual portion formats are significantly safer than shared platters. Individual portions allow each guest to check their own allergen information. They eliminate cross-contamination risk from shared serving. They ensure that dietary-specific items reach the right people without relying on staff to track and distribute them correctly.

Step 4: Communicate With Guests
For events with complex dietary requirements, communicate with guests about how their requirements will be accommodated. A simple line in the event confirmation — "dietary requirements collected at registration will be met; please confirm with [contact] if you have any concerns" — reduces anxiety and prevents guests from skipping the food out of uncertainty about whether their requirement has been captured.
Step 5: Event-Day Execution
On the day, ensure that the person receiving the catering delivery knows the dietary summary and can answer guest questions. For individual portions, ensure labelling is visible and guests can easily identify their items. Have a caterer contact number available in case of last-minute questions. For guests with severe allergies (particularly anaphylaxis risk), confirm their specific item with them directly rather than relying on them to identify it from general labelling.
When Things Go Wrong
If a dietary requirement is missed or a labelling error is identified before service, the correct response is to remove the affected item and contact your caterer immediately. Do not attempt to work around a mislabelled allergen item — the consequences of an allergic reaction at a corporate event are severe for the guest and legally significant for the organisation. Any caterer worth working with will have a rapid response process for exactly this scenario.
