Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to her Department's press release entitled Boost for British business as government slashes cost of electric lorries by up to £120,000, published on 6 January 2026, what estimate her Department has made of how much (a) carbon dioxide and (b) other pollutants will be prevented from being released as a result of the announced grant for electric lorries.

As of September 2025, there were 1,313 battery-electric HGVs on UK roads (VEH1103): https://www.gov.uk/government/statistical-data-sets/vehicle-licensing-statistics-data-tables.

The £18 million Plug-in Truck Grant Uplift announced on 6 January 2026, which runs until 31 March 2026, is estimated by the Department for Transport to support 195 battery-electric HGV sales. This equates to approximately 1.4% total HGV sales over January-March 2026. This is estimated to directly lead to 0.03MtCO2 emissions reductions over the zero emission (ZE) HGVs vehicles’ lifetime and is expected to support the acceleration of deployment of ZE HGVs in the UK, helping build a UK market for these vehicles which will increase their future adoption and help to deliver carbon budgets.

Estimates of the impact of the grant on ZE HGV sales are uncertain and will depend on demand. The truck grant is only confirmed to continue until the end of March 2026 so it is not possible to share 2030 fleet projections at this stage. Grant rates for any future truck grant from April 2026 will be published in due course.
