Every fee, threshold and deadline on this site was read off the issuing agency's own page on the date shown. Nothing is an industry average, a figure carried over from another market, or a number recalled from a previous job.

Fees change. Where a figure appears on a page it carries the date it was checked, so you can tell at a glance whether it is worth reconfirming before you rely on it.
