Where these figures come from
We take the government Fuel Finder dataset — the scheme forecourts must report their prices to — and keep a snapshot every day. Neither Google nor Fuel Finder itself stores history, so the week-on-week comparison comes from our own archive. Snapshot of 16/10/2026 15:00:03.
