Rock Road: Driving the Zero-Emission Bus Revolution

Since entering the market in 2016, Rock Rail has established itself as the UK’s leading financier of new rolling stock having purchased more than 40% (>£3bn) of all new passenger trains procured for the network. Now, under our new company ‘Rock Road’, we are building upon our success in rail to develop an analogous business proposition for the UK bus market in the context of an imminent zero-emission revolution.

Rock Road will provide operators with a fully integrated zero-emission bus (ZEB) system ‘as a service’ encompassing the finance, delivery and management of [1] required infrastructure upgrades, [2] energy supply chain, [3] a state-of-the-art ZEB fleet and [4] asset management services ensuring the optimal performance of the whole ZE system over its full life. Rock Road, alongside specialist partners, will provide holistic technology management services to optimise operational efficiency, preserve asset life and enhance value-for-money; all captured under a competitive lease rate charged to the operator.

Rock Road will provide a full turnkey solution for both battery and hydrogen powered bus to help accelerate UK operators’ ZEB rollout and overcome many of the barriers associated with a zero-emission transition such as high-upfront costs, long-term technology risk and a considerable increase in operational responsibilities. Our ZE system will be funded as infrastructure over its full life with Rock taking residual value risk following initial lease expiry, granting operators the vast benefit of operating a ZEB system while retaining the flexibility to adapt to advances in zero-emission technology as the market matures.

Rock Road also provides a disruptive and affordable approach which offers public transport authorities with the ability to revolutionise city-wide bus networks at the scale and pace necessary to drive down costs, transform cities and support the UK’s Green Industrial Revolution.

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.
