This is from the thai embassy website, january 10th is not mentioned however no new test and go applications will be considered, only quarantine or sandbox applications.
However if you have your thai pass already then they will be honoured.
You wont get in on a tourist visa! I rang the thai embassy earlier this month and was told no ring next month for an update, i also asked about the 90day visa and was told it is only available for people from the accepted countries list and that does not include the uk...
So im afraid at the mo its out of the question to go back!
