Short version: a government page, or nothing.
Every fee, validity period and eligibility line on this site is read from the issuing government's own page and carries the date it was read. Not from a law firm's briefing, not from a visa agency, and not from another travel site.
Where a government publishes no figure, this site publishes no figure. The field says Not published and stays that way. That is the opposite of what ranks, and it is the entire point: the invented version of exactly those fields is what the competition is built on.
Where a charge is made of parts, the site publishes the parts and the total the government states — never a total it worked out itself. A sum that looks right and is not is indistinguishable, to a reader, from one that is.
Some schemes have an expected timeframe reported by a government body and no announced start date. Those are different claims and this site keeps them apart: an expectation is reported as an expectation, with its source, and never presented as the answer.
This is the specific line that is crossed most often elsewhere, including on official pages.
Superseded figures are kept on the page, struck through, next to the figure that replaced them and the date it changed. A site about other people's numbers going stale cannot quietly delete its own history.
The same applies to what this site got wrong. Where a published claim has been corrected, the correction says so.
A watch job tracks a set of primary sources — the ones that move first when a fee or a rule changes, which is often a statutory instrument or a fee schedule rather than the traveller-facing page. The traveller page is usually the last thing to be updated.
Where a source has not been re-confirmed, the date attached to the figure says so. The date on a fact is the date it was last read, not the date the page was last touched.
