In London, Transport for London (TfL) has a policy that prohibits passengers from drinking alcohol or carrying open containers of alcohol on public transport, including buses, trams, tubes and the Docklands Light Railway (DLR). Bus services in England and Wales have different rules about whether you're allowed to drink or not. Around 80% of bus operators allow alcohol to be consumed onboard, but they often require a deposit or a cleaning fee for any possible mess they may cause. It's best to consume canned beverages and plastic cups, as most suppliers prohibit barrels or glass bottles to keep the coach clean and safe.
Bus operators across the UK often ask passengers not to drink alcohol on their buses. Alcohol consumption was banned on the London Underground more than a decade ago. Although it's not a strict rule, many bus and train companies recommend that people avoid eating smelly foods, especially hot ones, on public transport. As long as your bus provider allows it and you keep the bus clean, safe and legal for underage passengers, carrying alcohol on board should not be a problem.
Many bus and train companies limit what you are allowed to carry on board to prevent people from taking up too much space and making life difficult for other passengers. Always make sure your bus allows it with your reservation specialist and thoroughly review the details of your contract. As long as you follow these guidelines and know what type of bus best suits your group, you're ready to party.
