In accordance with EU Directive 96/96/EC, passenger cars are required to undergo a roadworthiness test when they are four years old and every two years thereafter. The age of the vehicle and consequently the first test due date are determined by reference to the date of initial registration with subsequent test due dates falling every two years after the first test due date. Non-use of a vehicle is not a criterion in determining the NCT test due dates. The extension of the validity of a NCT certificate by any period a vehicle is not in use would be a departure from the test schedule laid down in the directive and, accordingly, I have no plans to change the existing arrangements.
