National bus strategy
The government’s national bus strategy for England, 'Bus Back Better', was published on 15 March 2021.
It set out how local transport authorities and bus operators will work together to improve bus services in their areas.
The strategy required all transport authorities to work with bus companies, to create a bus service improvement plan (BSIP) by 31 October 2021. This strategy was updated in the autumn of 2024.
It led to the establishment of an enhanced bus partnership, between the council and bus operators to improve bus services for passengers.
For 2025/2026 the Department for Transport awarded £6.1million to spend in line with the BSIP and the delivery plan by March 2027.
