What do homes cost in Southwick?

Homes in Southwick sold for a typical £435,000 in the 12 months to September 2026, across 119 sales, HM Land Registry's figures show. The 12 months before gave £425,000 from 163 sales: not a change larger than chance would explain, given which homes happened to sell.

£435,000 typical price, the 12 months to September 2026

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

Across the whole BN42 district, Southwick's main postcode district: a typical £435,000.

Sales at the postcodes ONS places in Southwick: 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 Southwick?

5 of the 251 postcodes now in use in Southwick came into use in January 2020 or later, ONS says. In the 12 months to September 2025, 5 of the 163 homes sold in Southwick were newly built (3%), HM Land Registry's records show; across the BN42 district, 3%.

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 SouthwickAcross the BN42 district
The 12 months to September 2026 2 of 119 (2%) 2 of 108 (2%)
The 12 months to September 2025 5 of 163 (3%) 5 of 145 (3%)

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 Southwick at risk of flooding?

9 of the 251 postcodes in Southwick 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 32 homes and businesses in an area at high or medium risk.

Homes and businesses in an area at risk, at 9 of 251 postcodes High: 13Medium: 19Low: 26Very 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.
