Interesting, as the chap I work directly with got stopped on the M5 in 2017 for doing 96mph. He was clocked for a quarter of a mile at this speed, on a clear dry day with very little ahead of him (he showed us his dash cam footage). The Police Officer told him that it was unfortunate for him as the highest speed to be offered a COFP is 95mph.
He got fined £300 and 4 points on his licence.
The penalties go in 10mph steps. 95 on a motorway is Band C (91-100 MPH), so in theory can be 6 points or 7-56 days ban, plus 150% of weekly wages fine at court. The COFP limits are arbitrary, and different forces and even different officers can and do make up their own "rules". Sounds like this officer was short for his Christmas bonus. Or was his car yellow and they were playing Snooker ?

You'll get a NIP first to nominate the driver (within 14 days) . If you then get a COFP then chances are it'll be less than 100MPH. If it's 100+ then much more likely to be a summons to court. The summons must be issued within 6 months....
When it went over five months he started ticking the days off on his calendar. When it got to within a week he was overjoyed. He got home that night and it was through the letterbox.
Seems a bit harsh teasing people like that doesn't it.
Technically, they must "ley the informations" before the courts within 6 months. AIUI the police do that by computer link nowadays, so it means they have to file the forms with the court within 6 months ('puter says no'). The courts then process the data and generate the summons to the offender, and that can take another week or two. So you're not really 'safe' till about 7 months after the offence.
