One fee for all of them
TfL lists Knowledge of London appearances at £425 as a one-off payment. You pay it at your first appearance, and it is not refundable. Most candidates have many appearances across Stages 3 to 5, so the single fee is good news.
What is not covered
The written exam is a separate fee, £225 each time you sit it. TfL's table does not say whether Suburban candidates pay the same £425; its booklet says only that a fee is payable for appearances.
