Get a vehicle registration number

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.

Vehicles with a Certificate of Destruction (CoD) must never reappear as complete vehicles or be presented for registration, though some components may be recycled. You can’t keep the original registration or vehicle identification number.
