Today, 29 October, European Community Whole Vehicle Type Approval (ECWVTA) now includes multi-stage build trucks, special types vehicles and trailers, and special purpose vehicles.

Manufacturers, bodybuilders and the suppliers of these vehicles must now use one of the 3 new approval routes so that the vehicle can be registered before it can be legally used on UK roads:

We strongly advise you to make sure that any new vehicle has a type approval certificate before you buy.

This date also sees the demise of the Single Vehicle Approval scheme – special purpose light goods vehicles are now in scope of ECWVTA.
