Tipping bus drivers is not expected and very uncommon in the UK for standard local services. On public buses (like those in London or regional Arriva/Stagecoach lines), passengers simply "tap on" with a contactless card or show their pass, and no interaction beyond a "thank you" to the driver upon exiting is required. However, for long-distance coaches (like National Express or Megabus) where the driver assists with heavy luggage, some passengers choose to give a small tip of £1 or £2 as a gesture of thanks. For private tour buses or airport shuttle drivers, a tip of £5 to £10 for the group is appropriate if the service was exceptional. In 2026, the UK remains a largely "no-tip" culture for transit, so don't feel pressured; a polite "Cheers, Drive!" as you get off the bus is the most common and appreciated form of social currency.
