Across the whole RH13 district, Southwater's main postcode district: a typical £445,000.

Sales at the postcodes ONS places in Southwater: 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.

Are new homes being built in Southwater?

11 of the 236 postcodes now in use in Southwater came into use in January 2020 or later, ONS says. In the 12 months to September 2025, 5 of the 139 homes sold in Southwater were newly built (4%), HM Land Registry's records show; across the RH13 district, 2%.

The newest postcodes

A new postcode is often a new street or estate, but Royal Mail also makes new postcodes when it reorganises old ones, so not every one means new homes. Only postcodes still in use are counted.

New homes among the homes sold

PeriodIn SouthwaterAcross the RH13 district
The 12 months to September 2026 0 of 131 (0%) 2 of 474 (Under 1%)
The 12 months to September 2025 5 of 139 (4%) 10 of 537 (2%)

Standard sales of homes at market value that HM Land Registry marks as newly built. New homes take longer to be registered than other sales, so the latest 12 months count fewer of them than were sold. A share is given from 5 sales or more.

Is Southwater at risk of flooding?

1 of the 236 postcodes in Southwater has a home or business in an area at risk of flooding from rivers or the sea, the Environment Agency says. At those, it puts none of the homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 1 of 236 postcodes Low: 1

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.
