The UK Government has committed an additional £30 million to advance Cardiff Parkway railway station, with Transport for Wales set to play a leading role in delivering the project alongside Network Rail and both governments.
The funding, announced by Chancellor John Healey in the 2026 Budget, will support the next stage of the proposed station east of St Mellons, Cardiff, as part of wider efforts to improve transport connectivity and stimulate economic growth along the M4 corridor.
The announcement represents another significant development for the long-planned railway station, which has secured planning permission but has yet to begin construction.
Cardiff Parkway is designed as a four-platform station on the South Wales Main Line, providing connections between Cardiff, Newport and destinations further afield. The development is also intended to support a major new business district at Hendre Lakes, with the potential to attract employers and investment to eastern Cardiff.
The station was originally estimated to cost around £120 million, although the project is now undergoing a review of its costs and delivery arrangements.
Its initial financing model relied on private investment, supported by anticipated long-term revenues from station leasing and car parking. However, the project has since moved towards a funding arrangement involving the UK Government, Welsh Government and private investors.
The latest £30 million allocation provides a further public funding commitment, although the final cost of the station and the contributions expected from each partner remain to be confirmed.
The adjoining business park is being developed by Cardiff Parkway Developments Limited, a company principally backed by Investec and the Roberts family, in which the Welsh Government holds a minority stake.
The wider Hendre Lakes scheme has previously been promoted as a development with the potential to support approximately 6,000 jobs, although its eventual economic impact will depend on commercial investment, occupier demand and the pace of development.
The station is also linked to the wider programme of transport improvements recommended by the South East Wales Transport Commission, chaired by Lord Burns, following the Welsh Government’s decision not to proceed with the proposed M4 relief road around Newport.
Those recommendations placed greater emphasis on improving rail services, developing new stations and providing alternatives to car journeys along the heavily used Cardiff–Newport corridor.
Cardiff Parkway’s location near the M4 is intended to strengthen access to employment opportunities while providing a public transport alternative for commuters and businesses travelling across the region.
The project has also attracted scrutiny over its environmental impact, with the station and associated development planned on greenfield land at Hendre Lakes.
With planning approval in place and further UK Government funding now committed, attention will turn to completing the cost review, agreeing the remaining financial contributions and establishing a construction timetable.
For businesses across South East Wales, the key question is when the new station can move from an approved development into operational infrastructure capable of supporting the wider commercial ambitions for Hendre Lakes.
