Is there a minimum time requirement for holding the £11,000 financial evidence for a Thai visa application in London?

The Royal Thai Embassy in London requires financial evidence of at least £11,000 for visa applications but does not specify a minimum duration for which the money must be held in the account. Some users report differing experiences regarding the duration, with one mentioning a 3-month requirement based on their agent's advice, while others note that there is no such seasoning requirement.
