You need to send both your passport (proof of identity) and BRP (proof of right to reside in the UK)

Yes, they get sent to the Swansea address

If you don’t have an EU or EEA passport, you’ll need to send in a visa that proves you have permission to live in the UK.

A passport by itself does not contain this information anymore (as of 2015 when BRPs replaced in-passport visa stickers), therefore you must also send your BRP with your identity document (passport).

If you're only going to send in one document, it should be the BRP, not passport alone (unless of course the passport contains your full visa) because the BRP is a valid identity document AND shows immigration status

I've heard of people having a variety of experiences with DVLA and accepted documents, though
