Change vehicle details on a V5C registration certificate (log book)

Skip contents

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 must put in your V5C

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

  • colour
  • engine
  • cylinder capacity (cc)
  • fuel type – for example, if you convert your vehicle to run on electricity
  • seating capacity
  • weight of a large vehicle, for example goods vehicle or campervan
  • chassis, monocoque bodyshell or motorcycle frame, if their size or appearance is different from when your vehicle was made – find out about structural modifications

Telling DVLA about like for like changes

Even if you do not change the vehicle’s original appearance or dimensions, you must tell DVLA if you restore or replace your vehicle’s:

  • chassis
  • combined chassis and bodyshell (sometimes known as a ‘monocoque bodyshell’)
  • motorcycle frame

You do not need to update your V5C but you must tell DVLA using a Vehicle parts statement’ (V627/1).
