Putting a registration number on retention

[g7jhp]

I'm about to put a registration number onto a retention certificate.

Does anyone know if you use the V317 form or the V778 form (the DVLA site isn't clear)?

The V778 is the retention certificate. The V317 is the application form.

Just called the DVLA as Ithe info on both the V317 and V778 was contradictory.

The V317 is the only document now and is dual purpose (the V778 has been out of use for some time). Fee is £80.

I've just got my retention certificate in today. Definitely V317. Mine took about 14 days
