Overview
- The Chancellor is expected to permit TfL to secure loans for the extension with limited government underwriting, with precise funding details yet to be published.
- Construction is targeted to start in 2027 with services projected to begin in 2032, adding new stations north of the river at Beckton Riverside and in Thamesmead.
- TfL’s route would branch after Gallions Reach, cross under the Thames via a new tunnel, and terminate at an elevated Thamesmead town centre station.
- Treasury projections indicate the scheme could unlock up to 25,000 homes, around 10,000 jobs and nearly £18bn of private investment over the long term.
- Journey times are forecast to fall to roughly 25–30 minutes to Stratford and 20–25 minutes to Canary Wharf, with Mayor Sadiq Khan publicly backing the plan as essential for regeneration.
