Final numbers keep changing: quoting a wedding so a shrinking guest list doesn't cost you

The quote went out for 110. Eight weeks before the wedding it's 96. At the final-numbers deadline it's 88, and on the day 81 people sit down.

Which of those did you price?

Almost every wedding caterer has had some version of this, and it's worth taking apart properly, because the instinct on both sides is wrong. The couple assumes fewer guests means a proportionally smaller bill. Plenty of caterers respond with a blanket "no reductions" that's harder to defend than they think.

Why a smaller wedding barely costs less

Food scales with numbers. Almost nothing else does.

The staff you've committed to the date don't get cheaper when two tables disappear — a server looking after ten covers still works the full shift, and a chef doesn't prep a proportionally shorter day. Equipment hire works the same way: one tableware hire firm's published terms charge half the order for cancelling inside fourteen days and allow no reductions at all inside five. Some menus don't scale by the head at all. A whole hog roast costs what it costs whether sixty or ninety people eat from it.

Then there's the part that never shows up on a costing sheet. You held that Saturday. If you turned down another booking for it, that's gone whatever happens to the guest list.

The honest counterweight: if you use agency staff, some agencies let you cancel for nothing until a day or two before. So the "staff are committed" argument is strongest for your own team and freelancers who've kept the date for you, and weaker if you could genuinely have stood someone down.

As a rough guide to how much a missing guest actually saves you, published food-cost benchmarks for catering mostly put ingredients somewhere between a quarter and two-fifths of the price. None of them are specific to weddings, so treat that as a starting point for your own figures rather than an answer.

What other caterers' terms actually say

Fifteen sets of published booking terms from fourteen UK businesses — independent caterers, plus a few venues with in-house or linked catering for comparison — show a clear pattern. A caveat first: that's a sample of businesses that publish their terms, it leans towards England, and several share near-identical wording. It's a picture, not a survey.

• The deadline ran from about ten days to four weeks before the event, and two weeks was the most common.
• A minimum number of some kind appeared in twelve of the fifteen.
• After the deadline, nine charged the confirmed or minimum number, either explicitly or by clear implication. Three left any reduction to the caterer's discretion, and three didn't say. None offered a partial credit.
• Before the deadline, most said nothing at all about reductions.
• Late increases were generally welcome, billed afterwards and occasionally with a supplement for labour.
• Deposits were either a fixed sum, from £100 to £1,000, or a percentage, from 20% to 50% — and nearly all were described as non-refundable.

The pattern worth noticing is that flexibility tends to run one way. Numbers can go up late; they can't come down. That's commercially understandable. It's also exactly the shape of term that consumer law looks hardest at.

What the law says, which isn't the same thing

Common terms aren't necessarily fair ones, so it's worth keeping these apart.

There's no 14-day cooling-off period on a dated catering booking. The Consumer Contracts Regulations give most consumers fourteen days to cancel a contract made remotely or away from your premises, but regulation 28(1)(h) exempts catering where the contract provides for a specific date. A wedding booking does. You can still offer a cooling-off period if you want to, and some caterers do.

But "non-refundable" isn't a magic word. Under the Consumer Rights Act 2015, an unfair term in a consumer contract isn't binding on the customer. The CMA's guidance on unfair terms, revised in July 2026, is specific about the things wedding caterers' terms most often contain:

• Deposits. A genuine deposit that secures a booking can be kept, as long as the customer is told early and clearly when it won't be refunded — and it "will not normally be more than a small percentage of the price". A large prepayment kept regardless of circumstances is more likely to be unfair.
• Cancellation charges. These are more likely to be unfair if they don't allow for what the business saves by not delivering, what it can recover by re-selling the date, or the benefit of being paid early. A sliding scale can be fair, provided it's never disproportionate. A Scottish court upheld a 75% cancellation charge on its facts, helped by a clear table showing how the charge rose.
• Paying for something you no longer supply. A term is more likely to be unfair if the customer always pays in full whatever savings the business makes.

Weddings have had specific attention. In 2016 the CMA wrote to more than a hundred wedding and event venues about cancellation terms, and in 2018 Scottish trading standards officers reviewed 57 venues and found non-refundable deposits and charges of up to 100% commonplace.

So is charging for the final number fair?

Here's the honest position: nobody has ruled on it. Neither the CMA's guidance nor any court decision we could find deals with final-numbers clauses directly. What follows is a reading of the general principles, not settled law, and if a clause matters a great deal to your business it's worth a solicitor's hour.

On those principles, a final-numbers charge looks on reasonably firm ground when:

• The deadline sits where your costs actually commit. If food is ordered and staff confirmed at two weeks, a guest who drops after that saves you close to nothing, and charging for them is close to your real loss.
• Reductions before the deadline are credited in full. The couple has a genuine way to avoid the charge.
• It's explained at booking, prominently, with the reason.
• It isn't one-sided. If late increases are welcome, the treatment of late reductions should at least be explained on the same terms.

And it looks weaker when a minimum is fixed at quote stage months ahead and charged whatever happens, when "no reductions" kicks in as soon as the balance is paid eight weeks out, or when reductions are left entirely to your discretion with no explanation of how you'll decide.

Writing a clause that holds up

Putting that together into something you'd actually use:

1. Quote per head, with a stated minimum — and say in a sentence what the minimum is for. "Our minimum covers the staff, equipment and preparation that don't change with numbers."
2. Set the deadline from your own supply chain, not from habit. Work back from when you order food, confirm staff and confirm hire. If that's twelve days, don't write four weeks.
3. Credit every reduction before the deadline, in full, on the next invoice.
4. After the deadline, charge the confirmed number, and put the reason in the terms rather than leaving the couple to assume you're being awkward.
5. Keep the deposit small, and state exactly when it becomes non-refundable.
6. Say what happens to late increases, so the terms read as a rule rather than a one-way ratchet.
7. Collect dietary requirements with final numbers. For food that isn't prepacked, you must be able to tell customers if any of the 14 allergens are in a dish, so the final-numbers form is the natural place to ask. (In Scotland the regulator is Food Standards Scotland rather than the Food Standards Agency.)

None of this makes the conversation with a couple whose numbers dropped enjoyable. It does mean you're pointing at something they agreed to, that made sense when they agreed to it, rather than defending a rule.

Where grafter.ly fits

When a wedding enquiry comes in, grafter.ly lists what you still need to ask before you can price it: the date, how many guests, the venue and whether it has a kitchen, the style of service, dietary requirements and a budget per head. The quote is then built per head from your own price list.

Two things it doesn't do, so you're not relying on them. The date and the guest count are kept as the customer's answers rather than as fields anything counts down from, so your final-numbers deadline still belongs in your diary. And when numbers change, you change the per-head quantity yourself — on a new quote if they haven't accepted yet, or on the invoice before it goes out. You can try it free for 30 days, no card to start.

The short version

• A missing guest saves you the food and very little else.
• Most caterers use a minimum and a deadline, most often two weeks out, and charge the confirmed number after it.
• There's no 14-day cooling-off on a dated catering booking, but unfair terms still aren't binding.
• Put the deadline where your costs commit, credit reductions before it, keep the deposit small, and explain all of it at booking.
• Nobody has ruled on final-numbers clauses specifically, so the fairest version is also the safest one.
