Notes
- Defra's indicator F2a, which it gives rounded to the nearest 10,000. The Environment Agency's report words the same figure differently ("over 1.5 million" in 2025–26), and its file of registrations counts overlapping warning areas, so neither is a second route.
- Defra's indicators are not official statistics.
