## How CO6 compares

Each postcode district against every other postcode district the measure covers.

| Measure | CO6 | Rank | Compared with |
| --- | --- | --- | --- |
| Median sale price | £400,000 | 2nd most expensive | 16 postcode districts, CO · 2025 |

## Is CO6 safe? What police records show

In the 12 months to August 2026, police recorded crimes and anti-social behaviour in CO6 at a rate of 37.2 per 1,000 people.
That compares with 83.5 per 1,000 people across the CO postcode area.
In August 2026 alone, 104 cases of crime and anti-social behaviour were recorded in CO6.
In the 12 months to August 2026, the most common types were violence and sexual offences (534), other crime (204) and vehicle crime (99).
A year earlier, the recorded crime rate in CO6 was 38.8 per 1,000 people.
Worked out by Open Index from police.uk crime records and ONS and NISRA population estimates.
Rates are per resident, so places that many people work in or visit, such as Westminster, the City of London and other city centres, have far higher rates than their residents alone would suggest.
