seems normal from what im told, leeway…

The Association of Chief Police Officers (ACPO) has issued speed enforcement policy guidance, which suggests that enforcement will normally occur when a driver exceeds the speed limit by a particular margin. This is normally 10 per cent over the speed limit plus 2 mph. It also sets guidelines for when it would not be appropriate to issue a fixed penalty notice but to issue a summons instead (see below). Note that these are guidelines and that a police officer has discretion to act outside of them providing he acts fairly, consistently and proportionately.

Speed limit: 20 mph
ACPO charging threshold: 24 mph
Summons: 35 mph

Speed limit: 30 mph
ACPO charging threshold: 35 mph
