Up to Very low likelihood
Properties in CV47 2BZ sit in the Environment Agency's Very low 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% | 0 | 0 |
| Medium | 1% – 3.3% | 0 | 0 |
| Low | 0.1% – 1% | 0 | 0 |
| Very low | below 0.1% | 1 | 0 |
Over a 25-year mortgage, a property in a very low-likelihood area has less than a 3% chance of flooding at least once.
CV47 2BZ gets about 680 mm of rain a year on average (wettest month October, 69 mm; driest March, 43 mm). That is 42% 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 100 m above sea level and falls 19 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the south, 6.3 m higher.
The river map has no watercourse within 1 km of the centre of CV47 2BZ.
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 CV47 2BZ. 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 1998 | Ladbroke | ~0.7 km |
| Apr 1998 | April 1998 (Lower Severn) | ~0.7 km |
| Jan 1985 | M_LS_Jan_1985 | ~29.4 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.
| Gauge | River | Distance | Typical high | Highest on record |
|---|---|---|---|---|
| Eathorpe | River Leam | 11.1 km | 1.16 m | 3.25 m |
| Cropredy Bridge | River Cherwell | 12.7 km | 2.19 m | 2.80 m |
| Woodford Halse | River Cherwell | 12.9 km | 1.75 m | 3.27 m |
| Warwick | River Avon | 14.3 km | 1.46 m | 3.95 m |
Live levels, predictions and rain-response behaviour are on each gauge's page and in the property report.
