DVLA Retained Vehicle Identity for "Radically Modified vehicles"
Radically modified can just mean it had a few engines or gearboxes!
Each relevant part changed has a value associated with it.
Each vehicle begins with a set value, each change subtracts from that value if DVLA are notified.
If your vehicle reaches you have to re register your vehicle.
DVLA uses a points system to decide what registration number to give a radically altered vehicle.
Keep the original registration number
Your vehicle must have 8 or more points from the table below if you want to keep the original registration number. 5 of these points must come from having the original or new and unmodified chassis, monocoque bodyshell or frame.
Part Points
Chassis, monocoque bodyshell (body and chassis as one unit) or frame - original or new and unmodified (direct from manufacturer) 5
Suspension (front and back) - original 2
Axles (both) - original 2
Transmission - original 2
Steering assembly - original 2
Engine - original 1
Get a ‘Q’ registration number
You won’t be able to keep your vehicle’s original registration number if one of the following applies:
- it has fewer than 8 points
- it has a second-hand or altered chassis, monocoque bodyshell or frame
- there’s evidence that 2 vehicles have been welded together to form one (ie ‘cut and shut’)
Your vehicle must pass the relevant
type approval test to get a ‘Q’ prefix registration number.
I used to rebuild and restore Triumphs and a few lost their road tax exemption because of this!!!
