The average UK couple now spends around £272 on every guest, according to the Hitched Wedding Industry Report, published in January 2026 and based on 2,020 newlyweds. That is an average across the whole wedding budget, so it takes in far more than the meal. But it is a useful way to think about what each place at your wedding is worth, and it means every guest who has not replied is a small financial question mark sitting on your spreadsheet.
Most couples think of late RSVPs as an annoyance. They are really a budget problem, a time problem and, in the final fortnight, a pressure problem.
What does a late RSVP actually cost?
A late reply costs you money when it forces a guess on your final numbers, time every time you have to chase it, and calm in the last few weeks when you need it most. Here is how each of those adds up.
The money: paying for empty chairs
Your caterer will ask for final numbers before the day, often a few weeks ahead, and whatever you give them is usually what you pay for. Check your own contract for the exact date. If ten guests are still silent at that point, you either guess they are coming and pay for them, or guess they are not and risk them arriving to no seat and no meal.
Many couples choose to pay rather than risk it. On the Hitched average of £272 a head, ten unanswered guests represent £2,720 of planned spend that may never be used. The same report found 56% of couples went over their original budget, so that is money most weddings do not have spare.
The time: the hours nobody counts
Chasing is slow work: find the number, write something polite, wait, check, update the list. Do that for 30 guests and you lose several evenings in the month you can least spare them, the one with the final dress fitting, the seating plan and the speech you have not started. It also tends to land on one person, who quietly becomes the RSVP department.
The pressure: the final fortnight
The last two weeks should be about the wedding itself. Instead, many couples spend them refreshing a list and working out who still needs a nudge, or who has not mentioned an allergy. In thortful's wedding report, a survey of 500 people married in the last ten years, 49% said making sure it was perfect was their top source of stress. A half-finished headcount does not help.
Why do caterers need final numbers so early?
Because they have to order food, plan staff and lay tables before the day, and they cannot do that from a maybe. Alongside the headcount, most will also want each guest's meal choice, any dietary needs and allergies with names, and your table plan if they set the room. One missing reply can leave a gap in every one of those lists at once.
How can you cut the cost of late replies?
Make replying quick, ask for everything at once and remind people before the date rather than after it. Four changes make the biggest difference.
1. Set the deadline from your caterer's date, not the wedding date
Find the date your caterer needs final numbers and set your reply date a couple of weeks before it, so you have room to chase. Our guide on when to set your RSVP deadline walks through it.
2. Make replying effortless
A reply in a chat guests already use beats a card, a stamp and a trip to the post box. The fewer steps between reading the invitation and answering it, the fewer guests put it off. Our guide to collecting wedding RSVPs on WhatsApp explains how to keep every answer in one place.
3. Collect everything in one go
Attendance, meal choice, dietary needs and plus-ones should all come back in a single reply, so you never have to chase the same guest twice.
4. Chase early and kindly
A friendly nudge a week before the deadline works better than a panicked one after it. Our guide to chasing wedding RSVPs without the awkwardness has wording for each round of reminders.
Where AisleReply comes in
AisleReply sends each guest a personal WhatsApp message and they reply in the chat, in their own language. Meal choices and dietary needs come back with the same reply. Gentle reminders go out on their own, so nobody has to be the RSVP department, and you see a live headcount the whole way through. When your caterer asks for final numbers, you give them a real number, not a guess. That is the difference between paying for the guests who are coming and paying for the ones who never answered. Our help centre covers the details.
Questions couples ask about late RSVPs
Should I pay for guests who have not replied?
That is your call, and it depends on who they are. Close family who always turn up are usually safe to count in. Guests you rarely hear from are worth one more personal message before you decide.
Is it rude to chase wedding guests for a reply?
No. Most late guests simply forgot, and a short, warm message is usually all it takes. Keep it light and make it easy to answer.
What if a guest replies after the caterer's deadline?
Ask your caterer straight away. Some can add a place or two close to the day; others cannot. That is why a reply date with room before the cut-off matters so much.
The short version
Every unanswered guest is a cost you cannot pin down, an evening spent chasing and a little more pressure in the final fortnight. Set your reply date from your caterer's deadline, make replying as easy as answering a message, ask for everything in one go and nudge kindly before the date.
