Up to High likelihood
Properties in CH48 0QG sit in the Environment Agency's High flood-likelihood band (worst property). The band is the worst found in the postcode — it describes the land around properties (defence-adjusted, rivers & sea), not any single address, and not today's conditions.
| Likelihood band | Annual chance | Properties | Of which homes |
|---|---|---|---|
| High | greater than 3.3% | 3 | 0 |
| Medium | 1% – 3.3% | 4 | 0 |
| Low | 0.1% – 1% | 1 | 0 |
| Very low | below 0.1% | 0 | 0 |
Over a 25-year mortgage, a property in a high-likelihood area has at least a 57% chance of flooding at least once.
CH48 0QG gets about 772 mm of rain a year on average (wettest month December, 80 mm; driest March, 49 mm). That is 34% drier than the UK as a whole, which averages 1,163 mm a year.
A thirty-year average for the surrounding area, not a measurement at this address and not a flood risk on its own: a dry area floods when a storm sits over it, and a wet one may drain away perfectly well.

The ground here sits at about 7 m above sea level and falls 9 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the north-north-east, 2.1 m higher.
The river map has no watercourse within 1 km of the centre of CH48 0QG.
That means this spot is not on the river map, not that there is no water here: Ordnance Survey’s river map (OS Open Rivers) leaves out small streams, ditches and culverts. Contains OS data © Crown copyright and database rights 2026.

The map above shows the real EA rivers & sea likelihood cells around CH48 0QG. The small panels are illustrative previews of the report's per-layer map views — the full report draws each layer for real, plus recorded extents, defences and a building picker on an interactive map.
Warnings cover flood areas, not individual addresses.
| Date | Mapped flood extent | Approx. distance |
|---|---|---|
| Apr 2024 | West Kirby - 83 South Parade, 103 South Parade | ~0.5 km |
| Dec 2013 | ea013_051213_WestKirby | ~0.4 km |
These are extents the Environment Agency has mapped, not a list of every flood. Records, not floods: no outline on the record is not evidence a place has not flooded. The full report tests whether any extent covered the exact spot.
