It should be noted that non-sanction detections that contribute to the percentage change in detection rates have fallen in recent years reflecting a significant shift by many police forces away from recording detections of crime where no further action is taken. For this reason overall detection rates over time are not fully comparable.
From 1 April 2007 the rules governing recording of non-sanction detections were revised to reduce the scope within which they can be claimed to a very limited set of circumstance. In terms of offences detected by the police, the preferred measure is now to use sanction detections.
Detection rates are a ratio of crime detected in a period to crimes recorded in a period. They are not based on tracking whether individual crimes recorded in period have eventually been detected.

Up until the end of March 2009, PNDs were counted together with cannabis warnings.
