The criteria for substantial change
A vehicle will be considered to have been substantially changed (and hence not to have been historically preserved or maintained in its original state and to have undergone substantial changes in the technical characteristics of its main components) if it meets one of the following criteria. Such vehicles will not be considered of historical interest and will be continue to be subject to vehicle testing.
Criterion 1
If a vehicle has a power to weight ratio of more than 15% in excess of its original design, unless such a modification took place before 1988.
Criterion 2 If a vehicle:
 has been issued with a registration number with a ‘Q’ prefix; or
 is a kit car assembled from components from different makes and model of
vehicle; or
 is a reconstructed classic vehicle as defined by DVLA guidance; or
 is a kit conversion, where a kit of new parts is added to an existing vehicle, or
old parts are added to a kit of a manufactured body, chassis or monocoque bodyshell changing the general appearance of the vehicle.
While reconstructed classic vehicles and kit conversions can have age-related registration numbers that are more than forty years old, they are not VHIs. Radically altered vehicles should have registration plates with a “Q” prefix, but if a keeper considers they have such a vehicle with an original registration plate they should either test it or establish whether it is a radically altered vehicle.
