What are the bank statement requirements for Thai visa applications at the London embassy?

When applying for a Thai visa at the London embassy, the standard requirement is to submit 3 months of bank statements. However, it's noted that UK Immigration may sometimes request an additional 3 months (totaling 6 months) depending on specific document submissions that could trigger further financial scrutiny. Additionally, having a minimum balance of 500,000 THB or an equivalent currency seasoned in the bank account for at least 10 days is often recommended.
