Question to the Department for Transport:

To ask Her Majesty’s Government, further to the Written Answer by Baroness Kramer on 28 July (WA 257–8), whether they have considered conducting a reassessment, 10 years after the last, of the benefit-cost ratio of the Jubilee Line extension; and whether they intend to carry out any similar assessments of other infrastructure projects.

The Mayor and Transport for London (TfL) are responsible for the Jubilee line. TfL have no current plans to undertake a further evaluation of the benefit-cost ratio of the extension.

The Department for Transport takes a structured approach to understanding the benefits of projects once delivery of those projects has started. Actively managing the realisation of benefits will improve value for money and maximise the benefits for passengers.
