Group Holiday Budget Planner: How to Split Costs for 10–30 People

Whoever organises the group holiday becomes, whether they asked to or not, an unpaid accountant chasing eleven people for bank transfers. Having watched thousands of group bookings succeed and a few collapse, I can tell you the failures are almost never about the house — they are about the money. Here is the framework that keeps the kitty civil from deposit to checkout.

Anchor the number early

GoHen’s 2025–26 industry report puts a full UK celebration weekend at £250–£450 per person all-in — house, food, drink and one proper activity. That range is a useful sanity check for any group weekend, not just hens. State the target per-head number in the group chat before anyone falls in love with a house. People commit to £300 a head far more happily than they commit to a mystery figure that firms up later.

Deposits before booking, always

The iron rule: collect each person’s deposit BEFORE you book, not after. In our recent booking sample the median lead time was 82 days, and some groups book 11–14 months out — that is a long time for a “yes” to quietly become a “actually we have a thing that weekend”. Money is the only real RSVP. If someone will not transfer £50 today, they were never coming, and it is far better to learn that before you have committed to a 16-person house on their headcount.

The dropout maths, agreed in advance

Someone will drop out. Decide the rule while everyone is still friends: deposits are non-refundable unless the spot is refilled, and the balance is owed once the final payment date passes. Write it in the group chat when you collect the deposits — one message, no drama later. The organiser should never personally absorb a dropout’s share; the group does, or the dropout does. This single agreed sentence prevents 90% of group-holiday fallouts we hear about.

A worked kitty (illustrative)

An illustration of how the numbers tend to fall for 14 people, two nights, mid-range: house £2,400 + cleaning fee £250 = £190 a head. Shared food and drink shop £55 a head. One booked activity £45 a head. Kitty buffer £20 a head for the things nobody predicts (firewood, a forgotten birthday cake, the second supermarket run). Total: £310 per person, collected in two instalments — deposit at booking, balance six weeks out, matching the schedule most owners ask of the organiser anyway.

Run one channel, show your workings

One payment channel (a dedicated account, a pot, or one nominated card), one spreadsheet everyone can see, receipts in the group chat. Transparency is not bureaucracy — it is what lets the organiser send the third payment reminder without feeling like a debt collector. And the organiser’s own protection matters: never put the full booking on your personal card before the deposits have landed. Our cost-splitting guide covers the payment mechanics in detail.

Where the budget hides

The three costs first-time organisers miss: the cleaning fee (£150–£400 on large houses — check whether the quoted price includes it before comparing properties), the refundable security deposit (£300–£1,000, which someone has to front even though it comes back), and midweek-versus-weekend pricing — the same house is typically 30–40% cheaper Monday to Thursday, which for flexible groups is the single biggest lever in the whole budget.
