Well, the financial proof for the application to a 90-days Non-Imm-O Visa for "my elderly friend" is pretty high.
“Financial evidence e.g. A copy of a pension statement (more than £200/week) if the applicant is a pensioner and a copy of a 3-month bank statement showing your income from pension, or a 3-month bank statement of at least £10,000”
For an application to the SE Tourist visa, there is no more financial proof to be made (at least inside Europe, starting on October 28) Applied for at the Royal Thai Embassy London, the financial proof is just £500
