Turning transport ambition into delivery, for everyone who depends on it

Transport and infrastructure touches all of our lives, every day. As providers in this sector, you need solutions that deliver value to transport users and taxpayers and which help to drive local and national economies. We bring multidisciplinary expertise and deep practical experience to help you achieve your ambitions.
Changing travel needs, technology advancement, rail reform, bus franchising, ageing assets, strategic infrastructure investments, global trade and freight - these issues are reshaping how transport is planned, funded and delivered. We can help you to make the strategic, commercial and financial choices that keep people and goods moving.
We work across all transport modes with central and local government, operators, owners, asset managers and investors throughout the whole value chain for change and investment in transport - from an early idea, through the business case, regulatory regimes, commercial structuring, designing and implementing procurements, through to financial close and delivery.
We are supporting clients in the delivery of some of Europe’s largest infrastructure programmes, Including HS2 and the Euston redevelopment in the UK and Metrolink in Ireland. We have provided advice on Business Cases, Funding, Private Finance, Programme Assurance, Cost Verification and Procurement, among a wide range of services. Our team brings expert progamme capability and first-hand delivery experience of our major programme practitioners.
Our team has been at the leading edge of the evolution of the uk rail market for over ten years. From advising government and operators on franchising, through adapting the commercial regime during the Covid pandemic, through rail reform and the return of train operators to public ownership. We continue to bring that depth of knowledge and experience to help clients adopt and adapt to the changing market.
We are at the forefront of bus franchising, supporting local and combined authorities execute their plans under the Bus Services Act 2025. This includes strategy and planning advice, procurement execution and fleet strategies for operators.
We work with devolved governments and authorities to maximise the potential of their regions, delivering our full-lifecycle, cross-modal experience locally through our network of regional offices.
We have supported central and the devolved governments on their rolling stock strategies and have or are advising on almost all major rolling stock procuements in the UK. Our support ranges from business case development and procurement execution for the buying authority to bid strategy and execution for manufacturers. We have also provided support on innovative deals, like the sale and leaseback of a large new train fleet.
We work closely with our Grant Thornton international network to offer our services internationally. Recently we have helped procure the operator and maintainer for a metro project in the middle-east, supported in the design for a regulatory regime for a new railway in central America and supported the procurement of a new rail franchise operator in the US.
Aviation assets are capital intensive, long lived and, in many cases, regulated. That raises questions about what should be built, what it should cost, what return is reasonable, how to promote competition, how performance should be measured and rewarded, and what follows when parties disagree. We answer them with cost assessment and efficiency analysis, financial modelling and cost of capital work, the design and calibration of performance regimes, demand forecasting and economic appraisal, regulatory policy design, and competition, state aid and damages analysis.
