Are new homes being built in Great Dunmow?

14 of the 257 postcodes now in use in Great Dunmow came into use in January 2020 or later, ONS says. In the 12 months to September 2025, 20 of the 195 homes sold in Great Dunmow were newly built (10%), HM Land Registry's records show; across the CM6 district, 30%.

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 Great DunmowAcross the CM6 district
The 12 months to September 2026 3 of 128 (2%) 42 of 400 (11%)
The 12 months to September 2025 20 of 195 (10%) 195 of 657 (30%)

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.

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.
