The Department for Transport has announced a major HS2 reset, with revised delivery schedules placing first services between Old Oak Common and Birmingham between 2036 and 2039 and updated project costs estimated at between £87.7 billion and £102.7 billion. Transport Secretary Heidi Alexander confirmed operational and construction changes designed to reduce complexity, lower delivery risk and improve oversight across the high-speed rail programme.
The government published a package of documents alongside the parliamentary statement, including the latest six-monthly HS2 report, governance findings and updated assessments on project delivery and cancellation costs. The announcements follow a wider review of HS2 construction progress, supplier oversight and operational planning.
The revised delivery framework includes changes to train operating speeds, updated construction sequencing and renewed oversight measures modelled on approaches previously used during the Crossrail reset. Ministers said the project remains under active review as work continues on tunnels, stations and associated infrastructure across the route.
Government announces HS2 reset
The Department for Transport confirmed a formal reset of the HS2 programme during a statement delivered to Parliament by Transport Secretary Heidi Alexander. The reset includes revised construction schedules, updated cost estimates and operational changes intended to improve delivery confidence and reduce future project risks.
The government also published supporting documentation examining project governance, contractor oversight and delivery assumptions used during previous stages of HS2 development. These reports form part of a wider review into how the railway is being managed and delivered.
- Lead department: Department for Transport overseeing the revised HS2 delivery framework.
- Primary focus: Updated costs, timelines and operational changes designed to improve delivery stability.
Revised HS2 costs and delivery schedule
The updated government assessment estimates the total cost of completing HS2 at between £87.7 billion and £102.7 billion in 2025 prices. Ministers also confirmed revised operational timelines for the railway’s phased opening and wider route completion.
Under the updated schedule, first passenger services between Old Oak Common and Birmingham Curzon Street are expected between May 2036 and October 2039. The full route between Euston and Handsacre Junction is now expected between May 2040 and December 2043.
Updated HS2 Cost And Delivery Estimates
| Indicator | Recent Movement | Context |
|---|---|---|
| Estimated total cost | £87.7bn to £102.7bn | Updated figures published by the Department for Transport in 2025 prices. |
| Initial operations | 2036–2039 | First services expected between Old Oak Common and Birmingham Curzon Street. |
| Full route completion | 2040–2043 | Government expectation for full HS2 delivery to Handsacre Junction. |
Oversight reports and governance findings
Alongside the parliamentary statement, ministers released the latest parliamentary update and the Lovegrove review examining previous governance and delivery arrangements linked to HS2. The review assessed decision-making structures, cost assumptions and wider programme management practices.
The Transport Secretary said the reports highlighted long-running issues involving project complexity, delivery assumptions and contractor oversight. Government officials stated that updated delivery estimates were developed using revised methodologies and independent review processes.
Changes to speeds and project delivery strategy
The government accepted recommendations to align HS2 operating speeds more closely with other European high-speed rail systems. Ministers said the revised approach is intended to reduce engineering complexity and simplify testing requirements during later project stages.
The Department for Transport stated that the operational adjustment could reduce overall delivery risk while generating potential savings and improving construction sequencing. Officials said the revised speed profile would still place HS2 among Europe’s faster rail networks.
- Operational adjustment: HS2 speed profile aligned with existing European high-speed rail systems.
- Expected impact: Lower testing complexity and reduced long-term delivery risk.
HS2 Delivery Reform Measures
| Indicator | Recent Movement | Context |
|---|---|---|
| Supply chain oversight | Increased review activity | HS2 Ltd reviewing contractor incentives and supplier performance arrangements. |
| Operational speeds | Reduced from earlier assumptions | Government adopting lower-speed specification to simplify delivery. |
| Project oversight | Real-time reporting introduced | HS2 leadership receiving updated operational reporting to monitor delays. |
Construction progress and operational milestones
HS2 Ltd confirmed several major construction milestones were completed earlier than expected during the past year. Ministers also noted changes within the organisation, including reductions in back-office staffing and revised management oversight arrangements.
Construction activity continues across major sections of the route, including tunnelling works in London and station-related development around Birmingham Curzon Street. The government stated that supply chain contracts are also being reviewed as part of the reset process.
Government position on cancelling HS2
The government stated that cancelling HS2 could cost almost as much as completing the project while delivering none of the intended transport benefits. Ministers said cancellation would leave partially completed infrastructure and generate substantial remediation costs.
The Department for Transport confirmed that the government intends to continue with delivery of the railway under the revised framework. Officials said the updated strategy is designed to place future delivery on what they described as revised delivery assumptions and oversight structures.
Stakeholder Comments
Ministerial Comments
Heidi Alexander, Transport Secretary said;
“Today, I have accepted recommendations to reduce complexity within the project and align HS2 with speeds already delivered on other European high-speed networks.”
Mark Wild, HS2 Ltd Chief Executive said;
“HS2 Ltd has worked closely with government departments to assess the remaining work required and establish updated delivery assumptions.”
Wider implications for UK infrastructure delivery
The HS2 reset forms part of a broader government effort to improve delivery oversight across large-scale infrastructure programmes and long-term transport planning. Ministers linked the revised approach to approaches previously used during major UK infrastructure recovery programmes, including Crossrail.
Officials also said the updated programme reflects a revised delivery planning, oversight measures and construction sequencing. The government stated that HS2 remains central to future rail network capacity and operational integration planning across England.
The HS2 reset introduces revised cost estimates, delayed opening windows and operational changes intended to reduce delivery risk across the programme.
Government officials said updated governance structures, revised speed assumptions and expanded oversight measures are intended to stabilise construction sequencing while major infrastructure work continues across the route.
