What additional documents are required for a visa application at the London Embassy in Thailand?

DTV UPDATE: London Embassy. Submitted Monday 5:30pm, request for additional documents Wednesday 3:40pm - so around 46 hours

Request was:

* Photograph taken within the last six months.: - Please upload new photo (clear and focus) or use your mobile phone to take a selfie photo in plain white background and close up your head and top of your shoulders. (Your face must be clear and in focus and take up 70-80% of the photo.)

* Other request documents: - Self assessment tax return / Statement of accounts / Accountant's letter / Personal tax calculation or computation statement from HM Revenue and Customs (HMRC) (Apart form your name, you can conceal any details that you would not want to show.)

So I have taken and uploaded another picture and downloaded my self assessment (submitted earlier this year) from HMRC.

Fingers crossed they are satisfied and I won't need any more additional documents... who knows! I'll keep you updated!
