The short answer
Classic sweepstakes - a workplace Grand National draw, a World Cup sweepstake in the office, friends drawing Eurovision countries - are generally lawful in Great Britain when they are run as one of the exempt lottery types under the Gambling Act 2005, most commonly a work lottery. The key conditions are that it is private, and that nobody - especially the organiser - makes a profit from running it.
This page is general information about how the rules are commonly understood, not legal advice. If you are running anything beyond an informal private sweepstake, check the Gambling Commission's published guidance or take advice.
Why a sweepstake is a lottery, not betting
In UK law, a sweepstake is a form of lottery: people pay to enter, prizes are allocated, and the outcome depends wholly on chance - the random draw decides which entrant you get. That matters because lotteries have their own set of exemptions that betting does not.
The Gambling Act 2005 sets out categories of lottery that can be run without any licence. The ones relevant to sweepstakes are work lotteries, residents' lotteries and private society lotteries - together usually called private lotteries.
The conditions that keep an office sweepstake exempt
For a work lottery - the usual home of the office sweepstake - the commonly cited conditions are:
- Everyone taking part works for the same employer at the same premises (a residents' lottery is the equivalent for people living at the same address).
- It is not run for commercial profit: all the entry money goes back out as prizes, less reasonable expenses at most. The organiser cannot take a cut.
- Entry is not advertised or sold to the general public - it stays inside the workplace or private group.
- No rollovers: the prize fund is settled in that sweepstake, not carried into the next one.
An informal sweepstake among friends or family, with all the money paid out in prizes, is in practical terms treated the same way: a private arrangement between the participants.
What would take a sweepstake outside the exemption
The pattern in all of these is the same: the moment a sweepstake stops being private, or someone starts profiting from running it, it stops looking like an exempt lottery:
- The organiser keeps a percentage of the pot as a fee for running it.
- Tickets or entries are sold to the general public - including openly on social media.
- The sweepstake spans multiple employers or is opened to anyone who wants in.
- Prizes roll over from one draw into the next.
Where SweepstakeDraw fits
SweepstakeDraw is software for running the draw - it does not collect stakes, hold a prize pot or pay out winnings, and it is not a gambling operator. The optional £1.99 charge unlocks the tool itself and is not an entry fee or a cut of your pot. The sweepstake you organise, including any money your group collects and pays out, remains a private arrangement between you and your participants, run under the conditions above.
Two practical tips that keep everything comfortably inside the spirit of the rules: pay out the entire pot as prizes, and keep the sweepstake inside your workplace or private group rather than advertising it.
Where to check the official guidance
The Gambling Commission publishes plain-English guidance on running lotteries and sweepstakes without a licence, including the specific conditions for work, residents' and private society lotteries - search for "Gambling Commission organising small lotteries". Northern Ireland has separate legislation, so check locally if that applies to you. If your plans go beyond an informal private draw, that guidance - or proper legal advice - is the right next step.
