This happened to me about 15 years ago - I sent mine off for change of address and it came back provisional across the board. I fought the DVLA tooth and nail for years about it but they were adamant I had never passed my test. I ended up resitting my driving test. No, they won't believe any of your arguments and no they won't accept a photocopy. When we moved last year we had our conveyancing solicitor notarise a copy of both licences (Cat A bike on there now as well - no WAY I'd be resitting THAT one!)
