People will no longer be able to tax or register vehicles at Driver and Vehicle Agency offices in Northern Ireland, which close on Thursday 17 July.From 21 July, vehicle licensing will be delivered by the Driver Vehicle Licensing Agency (DVLA) in Swansea.Specifically, if people want to tax a car on Friday 18 July, the handover period of data to Swansea, they will need to go to the Post Office.DVA Chief Executive Paul Duffy explained: "It is important that anyone seeking to tax their vehicle knows exactly how the new system will work."The changeover to a new system should be as smooth as possible for local motorists."I have thus advised the DVLA officials in Swansea that they need to communicate with people taxing their cars here, as clearly and timely as possible."The staff in the DVA have provided a first class service to motorists here and have set a very high standard for the DVLA in Swansea to follow, when it takes over full responsibility for all vehicle licensing services from 21 July."The centralisation has cut 300 jobs at the eight DVA offices across the region as part of the closures, with most set to go in Coleraine.Environment Minister Mark H Durkan has transferred 70 posts to the Co Londonderry town and Social Development Minister Nelson McCausland has also outlined 100 roles that could provide work for former motor tax workers until the end of the year.The DVA's other functions of driver licensing; driver and vehicle testing; bus and taxi licensing and roadside compliance checks are not affected by the transfer of vehicle licensing to Swansea.
