There isn't a court charge in the UK anymore.
The only charges are costs.
However, they can offer you a fixed penalty fine.
And they can give you a caution at the police station.
If they have chosen not to though then there is no way of forcing them. This really should have been sorted out before the charge so that would tend to suggest that it is too late.
You could always get your solicitors to write to them offering a fixed penalty but they may well refuse.
Can I clarify anything for you?
Well, it won't happen realistically.
It would have been a decision of the police at the station. In fairness, you would have been offered a solicitor at the police station.
Ok. Best of luck
