Harnessing Private Finance for UK Rail Transformation

Last month’s meeting of the International Project Finance Association, chaired by Darryl Murphy, Aviva Investors’ head of infrastructure debt, included a diverse panel of public and private sector stakeholders including representatives from Network Rail, investor developer Rock Rail, engineering and project management specialists Atkins, legal advisor DLA Piper, and Japanese financial service company & major infrastructure lender SMBC.

As part of the report’s conclusion Mark Swindell suggested, “There will be a revolution around this. It will be a different way of delivering a major enhancement project to the railways. The enactment will not be done by Network Rail; it will be done by alternative risk-bearing, privately-financed companies.”

“These new structures will work in compliance with the current regulatory environment and railway stakeholders’ current roles and responsibilities,” he added. “However, the new private-sector rail asset owners will work with all rail stakeholders to specify required outputs and will seek bankable supply and maintenance arrangements. These structures will need to be driven by the private sector and presented as solutions to the DFT and rail stakeholders as a new way of bringing funding into the railways.”

Driving Net Zero: How Rock Road

The Challenge

The UK bus network is at the heart of everyday travel – but over 30,000 diesel buses still need replacing to achieve a fully zero-emission fleet.

While around 5,000 battery-electric buses are already on the road, the high upfront cost of electric vehicles and depot electrification continues to slow the transition. Traditional funding routes — such as government grants or short-term bank finance – have helped start the journey but cannot support decarbonisation at the scale required.

A new, sustainable funding model was needed: one that could attract long-term capital, spread costs fairly, and give operators and authorities confidence in the future.

The Solution

In 2021, Rock launched Rock Road to deliver exactly that –  applying its proven infrastructure financing approach from the rail sector to the UK’s clean bus revolution.

Working with Aviva, the National Wealth Fund, and HSBC, Rock created a dedicated investment platform that channels infrastructure-style finance from pension funds and institutional investors directly into zero-emission bus projects.

This model provides:

Impact

The platform has already raised £100 million, with capacity to scale to £1 billion per year over the next decade – providing a consistent source of affordable capital for local authorities and operators.

Rock’s model ensures that the total cost of ownership (TCO) of electric buses can now be lower than diesel equivalents, thanks to both cheaper long-term finance and reduced operating costs.

In London, Rock has financed 120 zero-emission buses under 7-year leases aligned with Transport for London’s contract lengths. This structure gives operators flexibility and certainty:

The Future

Rock Road’s ambition is to support the rollout of zero-emission fleets across the UK – helping local authorities and operators meet climate goals without overextending public budgets.

By leveraging limited government funding to attract large-scale private capital – for example, £10 million of public investment unlocking over £250 million in total funding – Rock’s model accelerates decarbonisation while keeping costs low for the public sector.

Our ambition is to make electric buses the default choice - not because of subsidy, but because they are the best economic and environmental option.
