Does L26 flood?

Yes — parts of the L26 district carry real flood risk: 21 of its 29 at-risk postcodes reach the Environment Agency's High likelihood band. The L26 postcode district covers Halewood North, Halewood South, close to Netherley, St Helens, Penketh, and surrounding villages in parts of Liverpool City Region and Cheshire West and Chester.

29 postcodes in the L26 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 21 high, 1 medium, 7 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
