No... absolutely 100% NOT. I assume it's a fixed penalty 3 points and 60 quid?!
Unless you challenge it (which is not always a bad option), and then go to court and get ''charged'' with excess speed, which would be a different scenario, and i suppose would show up on a CRB check.
But 3 points and 60 quid.... stop panicking!
And worry something else, like your IR
good luck
