HI. i saw your message...i was living in High Wycombe at the time, and i used BSM driving school.
They did all the paperwork, got the provisional license for me, scheduled the tests, etc
pretty smooth, even if it did take 3 months to get the appointments to takes the tests
Oh, BTW, anything you send to DVLA, send it "Signature Required" receipt returned, or you'll never get anything
