My new passport and driving license were (relative to the bureaucracy of government) very simple. I took an iPhone selfie with specific conditions (actually my wife had to take it).

I went online uploaded it, filled in a form with only a few stupid questions and then received my passport a couple of weeks later.

The driving license shared the same uploaded photo and was a renewal, so a couple of questions on an online form, a few GBP and again a couple of weeks later a renewed driving license arrived in the post.
