148 of the 3,684 postcodes now in use in Merton came into use in January 2020 or later, ONS says. In the 12 months to September 2025, 15 of the 2,463 homes sold in Merton were newly built (Under 1%), HM Land Registry's records show; across the SW19 district, 1%.
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
| Period | In Merton | Across the SW19 district |
|---|---|---|
| The 12 months to September 2026 | 5 of 1,658 (Under 1%) | 2 of 797 (Under 1%) |
| The 12 months to September 2025 | 15 of 2,463 (Under 1%) | 16 of 1,176 (1%) |
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.

What broadband can you get in Merton?
Ofcom reports on 3,503 of the 3,684 postcodes in Merton. At 2,885 of them every home and business can get gigabit broadband, and at 2 some cannot get decent broadband (10 Mbit/s).

Is Merton at risk of flooding?
378 of the 3,684 postcodes in Merton 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 2,078 homes and businesses in an area at high or medium risk.
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.
