Is SM3 at risk of flooding?

17 of the 379 postcodes in SM3 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 95 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 17 of 379 postcodes High: 63Medium: 32Low: 136

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 SM3?

Homes in SM3 sold for a typical £552,500 in the 12 months to September 2026, across 191 sales, HM Land Registry's figures show. The 12 months before gave £550,000 from 272 sales: not a change larger than chance would explain, given which homes happened to sell.

£552,500 typical price, the 12 months to September 2026
£550,000 12 months to September 2025
  • Detached £687,500 5 sales
  • Semi-detached £625,000 77 sales
  • Terraced £544,950 75 sales
  • Flat or maisonette £320,000 34 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.
