Approved in one day by the London embassy.
Applied Friday late afternoon.
Additional documents requested.
Sent those half an hour later.
Approval email came through Tuesday evening.
Long and short of it: Applied for the workacation category. Had the 500k thb spread across different accounts so sent bank statements from the past few months for current, biz and ISA. Sent a random selection of invoices from the past few years to show business viability. Wrote a quick letter saying I authorise myself to work remotely. Sent first page of incorporation documents and tax doc (just a letter saying it’s time to file). Sent drivers license and internet bill with address.
Additional documents requested were a formal letter addressed to the embassy introducing myself and my work, and stating I won’t be concerned with Thai laws or work with Thai clients. Also requested full company incorporation documents stating my name and position.
Prepared a formal letter and downloaded my incorporation documents direct from the public register. There was the option to order a certified copy of these but I just downloaded the pdf and sent that.
Approved.
