Bakerloo Line extension to Lewisham delayed until 2027

Transport for London (TfL) has announced a further delay to the Bakerloo Line extension project, pushing back the public consultation phase to later in 2027. The extension, intended to connect Elephant and Castle to Lewisham via Old Kent Road and New Cross Gate, has been subject to years of planning and campaigning but currently lacks a confirmed funding package or construction start date.

Bexley, Bromley, Croydon, Kingston upon Thames, Lewisham, and Sutton continue to rely on other rail and tram services.

The public consultation, originally scheduled between December 2026 and February 2027, has been postponed. TfL stated in a Freedom of Information response on 11 November that the revised timetable is dependent on factors including the implications of the Government's recent Budget and the publication of its updated business plan. Other public consultations, elections, and major announcements could also influence the timing. TfL is currently finalising consultation materials and working with affected landowners and local councils. Following the consultation, responses will be reviewed before a preferred scheme is selected, with TfL expecting to endorse this option in early 2028, contingent on the consultation's outcome.

Proposed route and potential further extension

The proposed extension would extend the Bakerloo line beyond its current southern terminus at Elephant and Castle. It includes plans for a new ticket hall at Elephant and Castle, a new station for the Old Kent Road area at Burgess Park, another station on Old Kent Road, and a new station at New Cross Gate offering connections to National Rail, London Overground, and bus services. Lewisham would see an improved interchange linking the Underground with National Rail, DLR, and local buses. TfL has previously estimated that the scheme could directly facilitate the development of at least 20,000 new homes along the route. TfL is also considering an additional extension beyond Lewisham to Hayes and Beckenham Junction, which would involve converting the existing National Rail route through Catford into part of the Underground network. The upcoming consultation is expected to examine three options: extending only to Lewisham, extending to Hayes and Beckenham Junction via Lewisham, or a phased approach with the Lewisham extension first, followed by the Hayes and Beckenham Junction phase.

Cost estimates and opening date

The cost of extending the Bakerloo line to Lewisham is estimated by TfL to be between £4.2 billion and £7.5 billion. These figures, based on January 2024 estimates and expressed in 2025 prices, could change as plans develop. A further extension from Lewisham to Hayes could add an additional £1.9 billion to £3.3 billion. While the Government's October 2026 Budget mentioned the extension as a project that could benefit from new financing powers for London, it did not provide a fully funded construction commitment. A separate Freedom of Information response in October 2026 indicated 2040 as the estimated opening year for the extension, subject to funding, planning, and public consultation. This suggests passengers may face a wait of over a decade. The project requires securing funding, completing further design work, and obtaining necessary legal approvals before construction can commence.

For residents in Lewisham, New Cross, and the Old Kent Road area, the latest update signifies that direct Tube access remains some years away. The project's future is dependent on securing the necessary funding and approvals to progress.
