When you need to update your V5C

You must update the details on your registration certificate (V5C) to tell DVLA about:

  • mistakes on your V5C
  • most changes you make to your vehicle

You cannot change tax class by updating your V5C. You do this by changing your vehicle tax - even if you’re changing to a tax class that’s exempt from vehicle tax, for example ‘disabled’.

Changes you need to update

You must update your V5C if you change any of the following:

  • colour
  • engine
  • cylinder capacity (cc)
  • fuel type
  • chassis or bodyshell (replaced or modified)
  • seating capacity
  • weight of a large vehicle, for example goods vehicle or campervan

DVLA will tell you if they need to inspect the change.
