Here is what each one actually charges, what the price does and does not cover, and what happens to the money if the evening falls through. Everything about another company is quoted from its own pages with the date it was read, and where a company does not publish a price this page says so instead of guessing.
What you pay, by service
Meetup
Membership is free and most listed events cost nothing to attend. Meetup also sells a member subscription, Meetup+, and its own help centre calls the free tier "the limited free plan" (help.meetup.com, read 4 September 2026). Meetup+ covers exemption from service fees on paid events, unrestricted direct messaging, waitlist priority and full access to the attendee list, member profiles and the "Who will be there" feature. Organisers can also set member dues for their own group, which is a separate charge again, flagged by a "Request to join" button. No Meetup+ price is published on the pages read, and its free trial rolls into a recurring subscription automatically.
So: often genuinely free, and the honest caveat is that seeing who is coming is behind the paid tier.
Timeleft
A subscription in one, three or six month periods. Its help centre says the available options "may vary by region and are displayed during sign-up" (help.timeleft.com, read 2 September 2026), and no price appears anywhere on its website or help centre. Food and drinks are paid at the venue and are not in the subscription. A subscription is generally non-refundable once a new billing period has started, including if you cancel on the day the renewal charges, and it renews automatically unless you cancel before the next billing date. There is no in-app plan switching: you cancel, wait for the current plan to expire, then buy the other one.
We are not going to fill in the missing number with one from a third party. If you want to know what Timeleft costs in London, you will find out during sign-up, which is a real thing to weigh if you are deciding tonight.
DayOfUs
Free to join, with a pay-per-event option or an optional subscription, and food paid at the venue (dayofus.com, read 4 September 2026). London is one of its listed cities.
Vairi
Not a dinner club, but a London option that deserves a mention here for one reason: it publishes its prices plainly in pounds, which almost nobody in this category does. Founding member plans are listed at 3.99 pounds a month, 9.99 pounds for three months and 19.99 pounds a year, with a free tier covering your profile, the first introduction and replying in anonymous chat (vairi.app/pricing, read 7 September 2026). It does one-to-one introductions rather than tables, so it answers a different question, but if publishing a price matters to you, it publishes one.
Supper clubs
Set per sitting by each host, usually with the food in the ticket. There is no market rate worth quoting and anyone who quotes you one is guessing.
KF.Social
15 pounds for the seat, shown before you pay, plus your own food and drinks at the restaurant. No subscription and no membership. You book the one Wednesday you are free, and there is nothing to cancel afterwards.
What the 15 pounds buys, precisely
It buys the seat and the work of filling the table, and it is worth being exact about that because "matching fee" is a vague phrase.
The dinner is Tuesday, Wednesday or Thursday, sitting at 19:00, in Soho, Shoreditch or Clapham. A table is laid for six, and a seventh booking is not turned away: another table of six opens rather than anyone being refused. Booking gates on being 18 or over and on paying, and on nothing else.
We book the restaurant, so you are not calling round at six o'clock trying to seat six people on a weeknight. Booking closes six hours before the sitting, and the restaurant lands at the same point. Who you are sitting with lands an hour before, with the group chat. Three hours before, we decide whether the table runs, against a floor of four seats.
The table is assembled rather than random. Anyone you have asked to avoid is never seated with you, and that is a hard rule rather than a preference. After that it is built for shared interests, close age bands and a balanced room, with a heavy weighting against seating you with people you have already met or sending you back to a restaurant you have already eaten at.
What it does not buy: your dinner. You order what you want and pay for it like anybody else at the restaurant, which also means a dinner club evening costs whatever you were going to spend on food anyway, plus 15 pounds.
What happens to your money if it falls through
Two different cases, and they are treated differently on purpose.
If you cancel, there is a ladder. More than 72 hours before the sitting, the 15 pounds goes back to your card. Between 72 and 24 hours it comes back as KF Points, which are credit toward a future dinner at 1,000 points to the pound. Inside 24 hours it does not come back, because at that point the table has been assembled around you and the seat cannot be resold.
If the table does not run, you are refunded in full whatever the clock says. The run or no-run decision happens three hours before against a floor of four seats, so if a table is short you find out at four in the afternoon rather than at the restaurant.
The awkward part of that ladder, said plainly: a cancellation inside 24 hours is the one case where you lose the money, and for somebody whose meetings overrun that is the rung that will actually bite. Booking the night you are least likely to be kept late is worth more than any refund policy.
