Each mark is a postcode's centre point as ONS gives it, not a building. Press one to see its postcode and open its page. A dashed outline shows where 5 or more lie within 150 metres of each other. It is not a boundary, and no boundary is drawn. Where marks overlap, the one first in the key is drawn; the counts include every postcode.

Are new homes being built in Harwich?

14 of the 494 postcodes now in use in Harwich came into use in January 2020 or later, ONS says. In the 12 months to August 2025, 6 of the 307 homes sold in Harwich were newly built (2%), HM Land Registry's records show; across the CO12 district, 16%.

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 HarwichAcross the CO12 district
