Property data for the CO2 postcode district covering Colchester. Sold prices, crime statistics, energy performance, and demographic insights, all from HM Land Registry, Police UK, and the EPC Register.
Quick answer
The average sale price in CO2 is £227,630 (median £227,500), based on 91 HM Land Registry transactions. Police UK recorded 214 crimes within a 1-mile radius in 2026-03. The average EPC rating across 40 certified properties is 61/100.
Headline pricing in CO2 is broadly in line with the UK national average (England & Wales average ~£290k as of 2025). Stock is dominated by detached properties (42 of the last 91 sales). Energy efficiency here is weaker than average (expect higher running costs and lower mortgage-affordability scores from green lenders).
