Can you keep the registration number if you want to rebuild your vehicle or convert it?

Not all registration numbers can be transferred. Your V5C will say if you can transfer the registration number. If you can you should consider:

• transferring it to another vehicle; or

• retaining it on a document before breaking up or carrying out any alterations or conversions. If you do not do this you may lose your right to the registration number.

For more information see Guidelines for the registration of rebuilt or radically altered vehicles and kit cars leaflet (INF26).
