Financial Close has been reached on the £600m financing of new Stadler trains for the Abellio East Anglia franchise. The Transaction was led by Rock Rail and SL Capital (part of Standard Life Investments) with additional co-investment equity being provided by GLIL, the Greater Manchester Pension Fund and London Pensions Fund Authority infrastructure investment joint venture. Senior debt is provided by a group of UK and international institutional investors together with the European Investment Bank. The debt composition was advised by DC Advisory.

Mark Swindell, founder of Rock Rail said:

“We are delighted to close our second rolling stock financing, especially in what have been volatile markets post the Brexit referendum. The highly competitive long term nature of funding provided by our Blue Chip institutional investors delivers best value for money to the East Anglia passengers and taxpayers over the life of the trains.”

Dominic Helmsley, Head of SL Capital Infrastructure said:

“SL Capital’s funding of this important upgrade to rail services in East Anglia signifies continued success of our joint venture with Rock Rail. We also see further potential to provide competitive funding for new rolling stock across the UK rail network.”

Driving Net Zero: How Rock Road 
Is Funding the UK’s Bus Transition

Accelerating the shift to clean, affordable, zero-emission transport

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.
