Bus passengers in England will face an increase in single fares from £2 to £3.
The previous limit of £2 was introduced under the Conservative government to help with the rising cost of living.
The new £3 cap, covering most bus journeys in England, will run until the end of 2025.
Holders of the Buckinghamshire Older Person and Disabled Bus Passes are still able to travel before 9am (Monday to Friday) for a reduced single fare of £1 on all journeys starting in Buckinghamshire until 31 March 2025.
