New regulations increasing the Category B licence weight limit for zero-emission vehicles are coming into operation in Northern Ireland from 1 August 2026. The Department for Infrastructure said the change follows a public consultation on measures to support the uptake of zero-emission goods vehicles.
The consultation considered whether changes to Category B licence entitlements could address regulatory barriers linked to the additional weight of zero-emission technology. The department said road safety remained a central consideration in the proposals.
From 1 August, the Category B weight limit for zero-emission goods vehicles will increase to 4,250kg maximum authorised mass. The regulations will also introduce a two-year licence-holding requirement for drivers using the new entitlement.
The department said Category B drivers will also be permitted to operate zero-emission goods vehicles up to 5,000kg maximum authorised mass where the additional weight is attributable to specialist equipment for disabled users. The measures apply specifically to the revised entitlements described in the new regulations.
Officials said the changes are intended to remove unintended barriers created by the extra weight of zero-emission technology. The department has said it will continue to monitor implementation and emerging evidence, including road safety data, as such vehicles become more common on Northern Ireland’s road network.
A consultation report, described as a synopsis of responses on proposals to change regulations supporting the uptake of zero-emission goods vehicles in Northern Ireland, has been made available by the department. The regulations come into operation two days after today’s announcement.
