7:20pm, and the table is still empty
It’s Saturday. The dining room is moving, the pass is busy, and a four-top booked for 7pm is still untouched at 7:20. The table was held because the booking looked solid. There was no phone call, no message and no cancellation. A walk-in party has already been turned away because the host couldn’t risk giving the table up too early. By 7:35 the kitchen has missed the chance to fill a prime slot, and front-of-house is left explaining why a room that feels busy has an empty table in the middle of service.
That’s what a no-show costs. You lose revenue in the part of the evening when you have the least spare capacity, and you lose the guest who was ready to spend and got turned away. It’s all the more frustrating because no-shows usually come without warning, and staff can’t refill a table they don’t know will be empty.
OpenTable’s consumer research has reported that 28% of diners admitted to no-showing a reservation in the previous year. That doesn’t mean every restaurant loses 28% of its covers; no-show rates vary widely by location, booking type and service. It does show that no-shows are common enough to need a proper system to manage them.
What no-shows cost in a normal week
Take a mid-size restaurant with 60 booked covers a night across five dinner services, an average spend of £32 per guest and a 5% no-show rate. That’s three missed covers a night. Three covers at £32 is £96 in unserved revenue each evening, or £480 across five nights. Over a four-week month it comes to £1,920, before you count drinks, dessert, tips or the walk-ins turned away while those tables were held.
The sum is deliberately simple, but it gives a manager something concrete to track. Start with your own booked covers, average spend and no-show rate, and look at Friday and Saturday separately from quieter midweek shifts. A 5% rate on a Tuesday may be manageable. The same rate at 7pm on a Saturday can cost you a whole extra table turn.
Why guests disappear
1. No reminder reaches them at the right time
People book restaurants on the commute, scrolling late at night or while making loose plans with friends. By the day of the reservation, the booking may be buried in an inbox or forgotten by whoever made it. A reminder is a service message, and guests don’t take it as nagging: it makes it easy to confirm, cancel or change the time before the table goes to waste. Timing matters. A confirmation straight after booking, a reminder the day before and a short same-day prompt at peak times give guests several easy chances to act.
2. The booking has no meaningful commitment
When booking takes no effort, cancelling can feel just as casual. If a guest can book a valuable Saturday slot with no card, no deposit and no clear cancellation policy, letting you know may feel optional. A small refundable deposit at peak times changes that without punishing genuine guests. It shows the table has value and gives both sides a clear way to cancel.
3. There is no waitlist ready to respond
Cancellations will still happen, and the waitlist often decides whether a cancellation costs you money. If a guest can join a waitlist for a preferred time, and the restaurant can offer a released table straight away, the slot can still be filled. A paper list or a message thread can’t move fast enough during service. The best systems notify the next suitable guest in real time and let the host stay in control of the offer.
A reminder system changes the odds
Results vary by restaurant, so compare your own data before and after you start sending reminders. The ranges below are for planning, and we can’t promise you’ll hit them, but they show why confirmation and cancellation messages deserve as much attention as your marketing spend.
| Booking setup | Typical planning range | Operational effect |
|---|---|---|
| No reminder system | 5 to 10% no-show rate | Late surprises and tables held too long |
| Automated SMS or WhatsApp reminders | 2 to 5% no-show rate | More confirmations and earlier cancellations |
| Reminder plus deposit for peak slots | 1 to 3% no-show rate | Stronger commitment where capacity is most valuable |
Three fixes to implement this month
Automate booking reminders
Send a confirmation as soon as a booking is made, then an automated SMS or WhatsApp reminder 24 hours before peak-time reservations. Include two clear actions: confirm or cancel. Don’t make guests phone during opening hours to cancel. Every early cancellation gives you time to contact the waitlist, adjust staffing or release the table.
Use small refundable deposits for high-demand slots
Save deposits for the times and group sizes where the risk is real. A £5 to £10 per person refundable deposit can be enough to prompt guests to act without making the booking feel hostile. Explain the policy in plain language, keep refunds simple and be reasonably flexible with guests who contact you early. Applying the policy consistently matters more than making it strict.
Build an active waitlist
Measure the result, then tighten the process
Track your no-show rate by day, time slot, party size and booking source, and track how far ahead cancellations arrive. A cancellation 24 hours ahead is useful information you can act on; a no-show at 7:20pm is a different problem. Review the numbers weekly with your front-of-house lead. If the same slot or type of guest keeps failing, adjust the reminder timing, the deposit rule or the waitlist size for that case instead of applying one policy to everyone.
Growtality’s smart booking system brings this together: automated reminders, clearer guest messages and waitlist backfill, with no extra manual work for the team. A cancellation is more likely to become a confirmed table, and guests get a simpler way to manage their plans.

Questions owners ask
How much do no-shows cost a restaurant?
For a restaurant with 60 booked covers a night, five dinner services a week, £32 average spend and a 5% no-show rate, that's three missed covers and £96 lost per night, or about £480 a week.
What's the best way to reduce restaurant no-shows?
Send an automatic confirmation and a reminder about 24 hours before the booking with a one-tap confirm or cancel, take small refundable deposits for high-demand slots, and keep an active waitlist to refill cancelled tables.
How much deposit should a restaurant take?
For high-demand slots and larger groups, a refundable £5 to £10 per person is often enough to prompt guests to cancel properly without making the booking feel hostile. Explain the policy clearly at booking.
