final numbers: when your venue needs them and what late drop-outs cost.

At some point in the last month before your wedding, your venue will send a short email asking for your final numbers. It looks like admin. It is actually the moment your guest list turns into an invoice.

Once you give that figure, most venues and caterers charge for it whether everyone turns up or not. So it is worth knowing when the date falls, what counts, and how to get to a number you trust.

Why the figure matters

Bridebook's 2026 UK Wedding Report puts the average wedding at 74 guests for the ceremony, with around 21 more joining in the evening, and average spend at £20,604. A lot of that spend is charged per head: the meal, the drinks package, chair hire, sometimes even the linen.

So a couple of guests either way is not a rounding error. On a per-head menu, two empty seats you have already confirmed are two meals you pay for and nobody eats.

When the date falls

There is no standard. Every venue sets its own, and it will be in your contract or terms. Common points are:

• A first estimate when you book, which sets your minimum numbers.
• Final numbers somewhere between two and four weeks before the day, when the kitchen orders food and the venue plans staffing.
• Dietary requirements and the table plan, often due at the same time or a week later.

Find the date now and put it in your planning calendar. Then set your RSVP deadline at least a week before it, so you have time to chase anyone who has not replied. Our guide to chasing RSVPs covers how to do that without making it awkward.

What to check in your contract

Read the catering and numbers section of your venue contract before you send the invitations, not after. Look for:

Minimum numbers. Many venues have a minimum spend or a minimum guest count. If your numbers fall below it, you usually pay the minimum anyway.

What happens after the deadline. Can you reduce numbers at all once they are final? Some venues allow a small drop with notice. Many do not.

Adding guests late. Usually easier than dropping them, but check whether there is a cut-off and whether the per-head price changes.

Children and suppliers. Are children charged at a reduced rate, and from what age? Do your photographer, videographer and band count as meals, and at what price?

Evening numbers. The evening food often has its own figure and its own deadline. Ask separately.

If anything is unclear, email the venue and ask them to confirm in writing. Our guide to venue contracts has more on what to look for before you sign.

How to give a number you trust

Your final figure should be the guests who have said yes, not the guests you expect. That sounds obvious, but it is where most mistakes happen.

Count confirmed guests only. Anyone still pending on the deadline is not in the number until you have heard from them. Chase them first, then count.

Count every plate. Add children, suppliers who are eating, and yourselves. Couples forget to count themselves more often than you would think.

Match the numbers across everything. Your final number should agree with the table plan, the meal choices and the dietary list. If the venue has 80 meal choices and a table plan with 78 names, something is wrong, and it is easier to fix now than on the day.

Keep one list. When the guest list lives in a spreadsheet, the RSVPs in a group chat and the meal choices in an email thread, the totals drift. A single guest list where each person is marked confirmed, pending or declined gives you the number straight away. That is how Build The Day works: the RSVP updates the list, and the count is always current.

When a guest drops out after you have confirmed

It happens. Illness, a cancelled train, a babysitter who falls through.

Tell the venue anyway. Even if you are still charged, they need to know for the table plan and place cards.

Ask what they can do. Some caterers will reduce the charge if they have enough notice to change the order. There is no harm in asking politely.

Move the seat, not the whole plan. Swap a place card rather than rebuilding every table. Leave the gap if it is on the edge of a table, and nobody will notice.

Do not chase the guest for the cost. It is part of hosting. Let it go.

A simple timeline

• When you book: note the final numbers date and minimum numbers.
• When you send invitations: set the RSVP date a week or more before final numbers.
• One week before final numbers: chase anyone still pending.
• On the deadline: send confirmed numbers, meal choices and dietary needs together.
• After that: tell the venue about any change, however small.

Final numbers are one short email. Get the count right and the rest of the week before your wedding gets a lot quieter.
