What are the financial requirements for a single entry tourist visa to Thailand from the London embassy?

The requirements for financial evidence when applying for a single entry tourist visa to Thailand from the London embassy seem to vary based on individual experience. While some users report needing only one recent bank statement showing a minimum balance of 20,000 baht (or its equivalent), others have submitted multiple statements, particularly when the required balance was higher, such as 500,000 baht in the past. It appears that the embassy has not consistently specified financial documentation requirements, leading to some confusion. It's advisable to provide an up-to-date bank statement that clearly shows your name and address as part of your submission.
