that’s correct. When the DTV is approved, they send you a pdf which you print out and show immigration when you arrive. The pdf has a QR code which immigration can scan to get details of your visa.
that’s right Tom. I think with the exchange rate you only need about £11,500 but I put 13 in there to be safe. They literally just want to see the money is in your account. No transactions or back statements requested. However, I hear with other embassies this is not the case. London honestly seems like the easiest embassy to apply from.
it’s all done online. You go to the Thailand evisa website. It asks you which country you’re applying from and then directs you to there. All docs are simply uploaded as pdfs or jpegs.
Most people find a random flight number and random hotel name if they do not already have these. However, proof of both in the past has been asked for and it is as always very embassy dependent.
If proof of hotel is requested at any point, it’s obviously quite easy to just book somewhere to get this. For flights you might want to use onwardflights.com before completing your application to avoid issues of proof being required.
