Normally for speeding in a 30MPH limit and being caught on a camera you would get a fixed £60.00 ( I believe it is now £75.00 including the victims of crime tax) and 3 points.
Because of the excess speed you will be appearing at court to explain the reasons behind it.
The minimum fine is £100 and the maximum £1000 ( £2500 on motorways) although these are means tested related.
I would plead guilty, appear at court in person apologise alot and grovel for the best outcome.
Had you been clocked at 60MPH in a 30MPH zone or above you would have been looking at a dangerous driving charge which carries a 1 year obligatory ban, up to a 2 year prison sentence and an unlimited fine.
