Dartford-Thurrock Crossing: Privatisation

Asked by Greg SmithConservativeDepartment for TransportTabled Answered 4 February 2026UIN 109246

The question

To ask the Secretary of State for Transport, whether the Department will treat the transfer of Dartford Crossing toll revenues to a private Lower Thames Crossing operator as a loss of income to the Department.

Answered by Simon Lightwood

The Government's preferred financing option at this stage is the Regulated Asset Base (RAB) model. Under the RAB model, ownership and operations of the Dartford Crossing would transfer to a new regulated private sector entity, which would be responsible for operating and maintaining both the Dartford Crossing and the new Lower Thames Crossing, ensuring a consistent and reliable service. This entity will be overseen by a regulator to ensure it performs and protects users. Charges from the Dartford Crossing and the new Lower Thames Crossing would be received by the entity under this model and this means charges will be used towards keeping the crossings well‑maintained and journeys running smoothly for users. This approach brings in private capital to fund the majority of construction, delivering better value for taxpayers and reducing the overall pressure on public budgets. The Department has built the effect of this into its financial forecasts.
