Euston cost pressure consistently reported as £0.4 billion despite expected reductions from design changes.
Recommendation
The Department has continued to report that the cost pressure at Euston was £0.4 billion throughout its six-monthly updates, including in the October 2022 update, which was the latest at the time we took evidence.46 Since October 2021, with the Department’s decision to change the design of the station to a smaller and less complex 10 platform single-stage build, the Department has stated that it expected that the cost pressure would be reduced.47 The Department also reported throughout 2022 including its latest update to Parliament in October 2022 that, as part of ongoing design work, it would need to consider the appropriate level of contingency to manage risks during construction of the station.48

5.1 The government agrees with the Committee’s recommendation. Target implementation date: December 2023 5.2 The HS2 Parliamentary report published in October 2022 set out HS2 Ltd.’s assessment of a £0.4 billion pressure for Euston station above its £2.6 billion budget, which was aligned with the range against which it had incentivised Mace Dragados to deliver the single-stage design, which was £2.6-£3.6 billion. Information regarding the significant additional pressure from the £4.8 billion revised estimate only became available in January 2023. In advance of the subsequent Parliamentary Report, which was published in June 2023, the department disclosed this transparently to Parliament through the National Audit Office. 5.3 The department is committed to upholding transparency in the HS2 programme.
