Is PO9 at risk of flooding?

198 of the 1,221 postcodes in PO9 have a home or business in an area at risk of flooding from rivers or the sea, the Environment Agency says. At those, it puts 1,130 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 198 of 1,221 postcodes High: 730Medium: 400Low: 814Very low: 5

High: 3.3% or more a year (1 in 30). Medium: 1% to 3.3% a year. Low: 0.1% to 1% a year. Very low: under 0.1% a year (1 in 1,000). Each band is the chance of flooding in any one year.

Homes and businesses in an area at risk of flooding from rivers or the sea, as the Environment Agency counts them, added up over the postcodes. It is for the land, not each building, and leaves out surface water, groundwater and sewers. Each postcode page has its own figures and its flood warning areas.

What do homes sell for in PO9?

Homes in PO9 sold for a typical £288,000 in the 12 months to September 2026, across 503 sales, HM Land Registry's figures show. The 12 months before gave £293,750 from 658 sales: not a change larger than chance would explain, given which homes happened to sell.

£288,000 typical price, the 12 months to September 2026
£293,750 12 months to September 2025
  • Detached £530,000 101 sales
  • Semi-detached £325,000 146 sales
  • Terraced £260,000 192 sales
  • Flat or maisonette £150,000 64 sales

Each bar is that kind's typical price, against the most expensive kind here.

Standard sales of homes at market value. A typical price is the median, the middle sale. Sales take weeks to be registered, so the last month or two are incomplete. Each postcode page gives the figure for its own postcode sector.
