Edinburgh Tram Inquiry

Completed
Chair Lord Hardie Judge / Judiciary
Established 01 Oct 2014
Final Report 12 Sep 2023
Commissioned by Scottish Government

Public inquiry into why the Edinburgh Trams project was delivered late, over budget, and with a reduced scope. The project cost £776m against an original estimate of £375m and took 5 years longer than planned.

Evidence & Impact
The Edinburgh Tram Inquiry, chaired by Lord Hardie, examined the troubled delivery of Edinburgh's tram project, which experienced significant delays, cost overruns, and contractual disputes. The inquiry was established in 2015 and reported in August 2023, making 24 recommendations aimed at improving the governance and delivery of major infrastructure projects.

The Scottish Government and City of Edinburgh Council responded to the recommendations in November 2023. The Scottish Government accepted 14 recommendations (58%) and accepted a further 7 in principle (29%), while considering 3 recommendations (12%) relating to civil sanctions and criminal offences for misleading evidence.

The Scottish Government's response frequently stated that it 'already operates in line with best practices for governance and light rail delivery' for several recommendations. For recommendations accepted in principle, the Government indicated that similar guidance was 'already in development' but provided limited specifics. The Government committed to considering updates to optimism bias guidance and noted that existing legal remedies might address concerns about misleading evidence.

The City of Edinburgh Council acknowledged the inquiry's findings about insufficient experience during the original tram project. Council Leader Cammy Day apologised for mistakes made and noted that improvements had been implemented for the successful Trams to Newhaven project. The Council's Chief Executive recommended adoption of most recommendations directed at the Council.

Published evidence of progress since the November 2023 responses remains limited. The Scottish Government updated general guidance on establishing public inquiries in November 2025, though this does not address all specific recommendations about inquiry establishment. The Council reported that improvements in ALEO scrutiny and documentation procedures had been embedded, citing reforms from 2012 and 2016.

However, no published evidence has been identified for many specific actions recommended by the inquiry, including establishment of joint working groups, implementation of conditional grant frameworks, production of new design guidance, or updates to optimism bias guidance for light rail projects. The pattern suggests acceptance of recommendations in principle but limited published evidence of specific implementation measures three years after the report's publication.
