Change vehicle details on a V5C registration certificate (log book)
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’.
This guide is also available in Welsh (Cymraeg).
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
Changes that may need inspection
You must also update your V5C if you change any of the following:
- wheel plan
- body type, for example you convert a van to a campervan or ’motor caravan’ (DVLA gives a body type description based on the vehicle’s external appearance)
- vehicle identification number (VIN)
- chassis number
- frame number for motorbikes
DVLA will tell you if they need to inspect the change.
