Large Goods Vehicles: Electric Vehicles

Question

To ask the Secretary of State for Transport, pursuant to the answer of 15 June 2026 to Question 8838, by what year her Department expects the total cost of ownership of zero emission heavy goods vehicles to reach parity with equivalent diesel vehicles without government subsidy.

Answer

The total cost of ownership is expected to fall over time as vehicle prices decline, and battery energy density improves. As these trends continue, battery‑electric Heavy Goods Vehicles are projected to become cheaper to operate than diesel across many duty cycles and under different use cases. This strengthens the commercial case for transition while also reducing greenhouse gas emissions, cutting harmful air pollution, improving public health and protecting the natural environment. There is uncertainty in the estimates of costs, and the exact timing of parity will depend on type of HGV and use case and speed of cost reduction of various elements of the cost. We continue to monitor and refine our analysis as evidence becomes available.
