A per-person session fee, often with a discounted monthly pass. Extra income can come from beginner lessons, private group bookings and selling sets or accessories.

• Knowing the rules of mahjong and how to teach them
• Welcoming and organising groups
• Promoting events online and locally

• Public liability insurance, and check whether the venue needs to see proof
• Keep play social: if money or prizes are staked on games, check the Gambling Commission's rules first
• If you play music or sell food or drink yourself, check licensing and food registration with your council, or let the venue handle it
• Check venue hire terms so a price rise or cancellation does not leave you without a home

Estimates suggest startup costs typically around £300 to £1,500, depending on how many sets and tables you provide, venue hire and insurance. Get quotes from venues and insurers to firm up your own figures.

Monthly revenue is typically estimated at around £300 to £2,000, depending on how many players attend, your per-session or membership prices and any venue arrangements. The estimates assume at least about 6 hours a week.

Check public liability insurance and whether venues need proof. If money or prizes are staked on games, check the Gambling Commission's rules first. If you play music or sell food or drink yourself, check licensing and food registration with your council.
