Adding a Guest with Dietary Requirements After Catering Approval: What to Put in the Change Request

1. Identify the approved version before describing the change

Begin with the order reference and the written confirmation you approved. Identify that version by its quotation reference, revision label or the date and time of the confirmation message. Include the event date and your usual order contact so the amendment can be matched to the correct booking. If approval happened in a long email chain, attach or quote the relevant confirmation rather than expecting someone to reconstruct it.

State the scope in the first sentence: ‘The request below changes one guest’s meal; the remaining menu is unchanged, subject to your confirmation.’ Do not describe a new preference as already accepted. Separate your requested changes from the supplier’s confirmed changes throughout the conversation. This distinction matters when several colleagues are copied in and a proposed menu could otherwise be mistaken for an approved instruction.

2. Show whether the guest is additional or replacing a meal

The dietary meal count and the overall headcount answer different questions. Write whether this is an additional attendee, a replacement for someone who has withdrawn, or a different meal for an existing attendee. Then show the old and requested new quantities for every affected category. Avoid ‘add one vegan’ if you actually mean ‘replace one standard meal with one vegan meal’; the first wording can cause a duplicate order.

For a hypothetical individual-meal order, replacing one of 24 standard meals would give 23 standard meals and one requested dietary meal, with 24 meals overall. If the guest is additional, the request would be 24 standard meals and one requested dietary meal, with 25 overall. These are counting examples, not package sizes or availability claims. For shared trays, ask the supplier how the extra guest affects portions instead of assuming that a single-person adjustment is possible.

3. Get a precise requirement without collecting a health history

Ask the guest which ingredients must be excluded and whether they need you to raise any preparation or cross-contact requirements with the caterer. Keep a preference, an allergy-related request, an intolerance-related request and a religious requirement distinct rather than compressing them into ‘special diet’. The IACC guide to special diets in meetings supports structured collection of different dietary requirements and discussion with the venue about what can be accommodated.

Collect only information needed to assess and identify the meal. You do not need to request a diagnosis, medical records or an explanation of the guest’s beliefs. A private message and a guest or meal code can keep the working order clear without circulating sensitive details to an entire department. If the guest’s wording is unclear, ask them to clarify it; do not decide on their behalf that a less specific restriction will be enough.

4. Distinguish vegetarian changes from vegan changes

If the guest requests a vegetarian meal, confirm whether eggs and dairy are acceptable and record any other named exclusions. The Vegetarian Catering page is a starting point for menu enquiries, but the change request still needs the guest’s actual requirements. A vegetarian menu name does not establish that a dish is vegan or suitable for an allergy-related restriction.

If the approved meal includes egg or dairy components that the guest cannot accept, use Vegan Catering to discuss a different option rather than simply relabelling the existing meal. Ask the supplier to review accompaniments and dessert as well as the main dish. A vegan request does not automatically cover gluten or other allergens, so list any additional restrictions separately, even when they apply to the same guest.

5. Review the whole meal, not only the main dish

Use the approved menu as a component list. Mark the affected main, starch, vegetables, garnish, dressing, sauce, dip and dessert, then ask what remains unchanged and what needs replacing. If a lunch includes a separate snack or drink, check that too where the restriction is relevant. Do not assume that removing a visible ingredient addresses ingredients already used in a sauce or another part of the meal.

Ask for a named proposed replacement, not merely an assurance that ‘something suitable’ will be packed. A clear response could identify the revised main, the retained side and the replacement dessert, alongside any unresolved limitations. Keep proposed alternatives marked as pending until both the relevant requirements and the order implications have been checked. This gives the guest something concrete to consider without suggesting that a menu label alone settles suitability.

6. Record halal requirements in the guest’s own terms

Where the late request concerns halal food, ask what the guest needs confirmed about ingredients, sourcing, preparation and any supporting documentation. You can use Halal Catering as the menu enquiry route, while asking the supplier to respond to those specific points. Do not infer certification or accepted preparation practices from a page title, a photograph or the absence of pork.

If the supplier suggests a vegetarian alternative, take that suggestion back to the guest with the relevant ingredient and handling information. Do not treat it as an equivalent replacement without their agreement. Goode Catering’s dietary-requirements guide recommends following up when requirements are unclear and asking about menu changes, charges and relevant qualifications. That supports asking better questions; it does not verify any qualification held by your chosen supplier.

7. Separate gluten-related ingredients from handling questions

For a gluten-related request, identify the guest’s stated exclusions and ask about the ingredients throughout the meal, including sauces, coatings and accompaniments. The Gluten-Free Catering page provides a place to enquire about options, but you still need a response about the particular dishes and handling arrangements proposed for this amendment. If there is an allergy-related or coeliac-related handling requirement, record it explicitly rather than leaving the supplier to infer it.

Keep the ingredient question separate from the cross-contact question. A replacement ingredient or removal of a garnish does not establish how food is prepared, packed or served. Ask the supplier to explain the measures it can offer and the limits it cannot address. Do not translate that reply into an allergen-free or coeliac-safe guarantee. The guest and supplier need to resolve whether the actual arrangement is acceptable; the organiser should not make a medical safety judgement.

8. Agree how the revised meal will be packed and identified

Ask whether the amended meal will be individually packed, how its components will be identified, and whether any sauce or dessert will arrive separately. If the event uses shared platters, explain that setting and ask what serving arrangements would be needed for the requested meal. A separate box can help identify an order, but packaging alone is not evidence that the required preparation or cross-contact controls have been met.

Use a simple meal code that the receiver can match to the latest confirmation. Agree who will recognise that code and hand the meal to the guest, especially if a reception team receives the delivery before the organiser arrives. Avoid a public label containing unnecessary personal information. If the supplier cannot provide the requested identification or separation, resolve that limitation before approving the amendment, rather than relying on someone to recognise the food by appearance.

9. Recheck the amendment deadline and delivery window

Send the requirement promptly and ask whether the change can still be assessed and accepted. The Side Street article on last-minute catering changes describes confirming the exact adjustment, evaluating the implications and notifying the relevant teams once arrangements are settled. Its practical lesson here is to communicate the change immediately, not to assume another supplier shares its capabilities or terms.

Ask two separate timing questions: by when must you accept the revised proposal, and can the original delivery window still be retained? If the request arrives on the event day, Same Day Catering is an enquiry route for that day’s feasible menus and delivery arrangements. It is not confirmation that a dietary amendment to an approved order can be completed that day. Do not promise a special meal based on general same-day availability.

10. Obtain a revised total before seeking approval

Ask for the financial change and the revised overall total, including any affected packaging, delivery or service items. For a replacement, ask whether the removed meal changes the charge; for an additional guest, ask how the added quantity is priced. Neither a refund nor a surcharge should be assumed. Confirm any payment difference and when it must be settled, using the supplier’s actual response rather than estimating from a different menu.

Return the affected cost or menu decision to the original approver, or to a person authorised to approve it. A colleague’s helpful suggestion is not necessarily budget approval. If the total remains unchanged but the agreed menu changes, the organiser may still need to approve that substitution. The IACC guide includes extra charges, deadlines and last-minute arrangements among the points to discuss; it does not establish a universal fee or amendment deadline.

11. Send one change record and obtain a replacement confirmation

A useful catering order change request for dietary requirements keeps each affected item in a simple sequence: original value, requested new value, supplier response and approver. Include the quantity change, the precise restriction, the proposed replacement and any timing or cost question. Keep the unanswered items visible. This is more reliable than scattering updates across separate messages in which different people approve different parts of the meal.

After the proposal is accepted, request updated written confirmation identifying which earlier version it replaces. Check the final quantities by meal type, the accepted requirements and any unresolved or unsupported restrictions, the revised total, the delivery window and the agreed identification code. Ask who has received the amendment for preparation, packing and delivery. Acknowledging that a message was received is not the same as confirming that the requested change has been accepted.

12. Close the loop with the guest and the receiving team

Before confirmation, tell the guest that you have submitted the requirement and are checking what can be accommodated. Once the revised order is confirmed, share the agreed meal description and any relevant limitations privately. Give the receiver the current quantity breakdown and meal code, and make the superseded confirmation clearly distinguishable from the live version. At delivery, compare the received meal and label with that version; if something is missing or unclear, contact the supplier rather than guessing.

If the supplier cannot meet the requirement, explain the specific limitation to the guest and discuss an alternative they can accept. That might require a different arrangement rather than a substitute from the existing menu. Do not silently replace an unavailable dietary meal with a general vegetarian option or suggest that speed resolves a handling concern. The amendment is complete only when the accepted arrangement, its costs and its handover are clear—not simply when someone has offered a possible dish.
