A one-hour Hopper ticket is being introduced in London to make travelling by bus cheaper and more convenient.
Currently passengers must pay £1.50 for each bus ride, while taking a tram costs up to £2.60 a time. But the scheme, which begins on Monday, means travellers who pay a £1.50 fare can change on to another bus or tram for free within 60 minutes of touching in at the start of their journey.
The fare will automatically be given to anyone who uses Pay As You Go with Oyster, or contactless payment cards.
London mayor Sadiq Khan said: "From my first week as mayor, I was determined to get on with the job of cutting the cost of transport in London. I'm delighted to announce that, from next Monday, the Hopper ticket will allow Londoners to change buses for free within an hour, cutting travel costs for millions of bus users.
"Fares in London have risen for eight years in a row - and, for people who have to change buses to get to work, the system simply isn't fair. We must ensure that everyone can afford to travel around our city and, for people on low incomes, the cost of travel must never become a barrier to work or study.
"The new Hopper ticket means 30 million bus journeys every year will now become free - journeys that currently cost people £1.50. Alongside our commitment to freeze all TfL fares, the start of the Hopper next Monday is a key part of our plans to make it more affordable to live and work in London."
From 2018, passengers who travel on a Tube or train will also be eligible for the Hopper fare.
