Months of data3
Per month476
Severity-weighted crimes per km² per month61.9 per km² per month
Search radius1.6 km

Recorded street-level crime within the search radius, weighted by offence type (violence and robbery x2, ASB x0.5), per km² per month, placed on a log scale from 1 (scores 100) to 300 (scores 0).

  • Counts recorded crime by location, not risk to any individual; busy city centres score lower because of footfall.
  • Locations are anonymised to nearby map points by the police.

Starts from the Environment Agency flood zone (Zone 1: 95, Zone 2: 60, Zone 3: 25), minus 10 if a flood warning area lies within 1 km (5 if only an alert area), minus 15 per active flood warning and 5 per active alert; a severe warning caps the score at 10.

  • Flood zones show the chance of river or sea flooding ignoring defences; they do not cover surface water or groundwater.
  • This is not a flood search. Use a professional search before buying.

The SAP energy efficiency rating from the EPC (1-100, the number behind bands A-G): the property's own certificate when we can match the address, otherwise the median of the latest certificate for each property in the postcode.
