To answer your first point, no, I did not say nor imply, that Immigration did not need to see evidence of monthly income. Previously, I have made it very clear that Immigration did need to see monthly income for each and every month of the year. In my own case, I submit a full spreadsheet, broken down with monthly totals, the source of which is Transferwise. I do this because I have 3 sources of UK income (pensions) that are payable at different times of the month. I can, and do, transfer these payments as and when I feel the bank rate is looking good. Secondly, this breakdown is fully supported by a 12-month Thai bank statement. I highlight the monthly transfers that correspond exactly to the first spreadsheet. The only difference, the Thai bank statement does not show the total sum transferred each month. Finally, I prepare the third spreadsheet, that totals my 3 pensionable incomes, supported by the annual statements provided by the pension providers, that shows my total UK income for the year. This effectively is the same information, with supporting documents, that the letter of income from the embassy provided. I successfully used this format to substantiate my monthly income some 12 months ago and intend to do so again this year.
