Cambourne to Cambridge - Independent Audit
The Cambourne to Cambridge project was audited in early 2021. The findings of the audit were presented to the Greater Cambridge Partnership Executive Board on 1 July 2021. The auditor examined the key assumptions and constraints, which led to the selection of the preferred route for the scheme and to the rejection of alternative options. They also tested the robustness of those assumptions and constraints to see whether they remain appropriate.
How was the audit carried out?
An independent auditor, Mr Phil Swann, was appointed in January 2021 to oversee the audit. Mr Swann:
- established the terms of reference for the audit, and commissioned an independent transport expert to carry out the audit,
- reviewed the assumptions and constraints that have led to the selection of a recommended preferred route ,and invited representative groups to submit written representations,
- oversaw the audit process and reported the findings to the GCP’s Executive Board in July 2021.

The audit report was updated in November 2021 to correct references to the report titled: 'Cambourne to Cambridge: In-Highway Proposals for High Quality Public Transport Scheme'. The report now correctly attributes the authorship of the report to Edward Leigh rather than Cambridge Connect on pages 4, 58 and 59. These changes do not alter the conclusions of the report. The original version of the audit report was published in the Executive Board agenda for July 2021 (page 364 onwards). The final report is available in the document section below.
What were the conclusions of the audit?
The audit concluded that:
- the project should proceed to the next stage
- the scheme is aligned with national, regional and local policies on economy and transport,
- stakeholder engagement has been carried out in a robust manner,
- and the business case development followed the HMT Treasury Green Book and the Department for Transport’s TAG methodology.
- The appraisal has also been carried out in a robust manner, and the economic analysis and financial case remain valid.
- The environmental impact of the scheme is mixed and the validity of some of the assumptions will need to be investigated further as part of an Environmental Impact Assessment which would form part of the next project stages.
- The GCP has complied with national guidance on how to balance local and national considerations.
- Overall, the audit has confirmed that the key constraints and assumptions on which the C2C business case is based remain valid.
