How we verify every price
Data from 10 Jun 2026 to 21 Jun 2026ParkMath's whole value is that the numbers are right. Here's exactly how each UK airport fee is sourced, date-stamped, and kept current — so you can trust the figure you see.
Every figure comes from the airport's own official page
Each airport's drop-off and parking fees are read directly from that airport's own official website — never copied from a comparison or aggregator site. We keep a source registry that pins each of the 25 airports we track to its official source URL, so every number is traceable back to where the airport itself published it.
Each price is date-stamped when it's verified
When we confirm a figure against its official source, we record the date as
verifiedAton that record. That's the date you see in the green “Verified” badge next to a price. It means: on this date, this exact figure matched the airport's official page.We re-check on a schedule — and before every content update
Fees move, typically at the January and April fiscal boundaries. So we re-run a freshness check that re-fetches each airport's official source and compares it to what we have stored, classifying every record as current, stale, conflicting, or unverifiable. Anything that isn't a clean “current” match gets a human look before anything changes.
When an airport's page blocks a simple fetch, we use a real browser
A handful of airport sites block automated requests. For those, the check escalates to a real rendered browser to read the official tariff table directly, and falls back to an official-domain search only as a last resort — still never a third-party aggregator. The source of truth is always the airport itself.
Nothing is auto-published, and nothing is invented
The freshness check is read-only by design. It never edits the dataset and never publishes a price on its own. Any change it spots is surfaced as a reviewed diff that a human approves before it goes live — and we only ever change a value we can verify against an official source. If we can't verify a number, we don't present it as fact.
What “Verified [date]” means
A green Verified [date]badge means that, on the date shown, the figure matched the airport's own official page. If a price hasn't been re-checked in a while, the badge turns amber and reads “Last verified”— a signal to double-check with the airport before you travel. Either way, the date is honest: it's the last time a human-reviewed check confirmed the number, not a timestamp that auto-refreshes to look current.
