BOSSREG - Number One For Number Plates

I have a number on 'retention' which I would like to assign to my vehicle. However, I already have a 'special' number on my vehicle and I wish to transfer this in order to have my retained number assigned. How do I go about it and how much will it cost?

We are able to offer this service to you as part of our transfer package, or you should complete the forms as directed. However, in addition to the documents outlined in question 4, you must also present the V778 Retention Document, duly signed, with the application. These should be accompanied by the £80 transfer fee and where the number was put on retention prior to 1 May 1993, the £80 assignment fee.
