I have had a read through this thread as I have an old Halifax account with charges but all are from 1999 and 2000 so more than 6 years ago. As I understand it, claiming solely for charges over 6 years is unlikely to succeed as it hasn't been established in court that the charges are unlawful and they will go to court to argue this? But claiming for older charges along with those within 6 years may well be successful because they won't actually want to go to court in case the court decides they are penalties. If this is the case, would people still recommend attempting to make a claim for charges that are all 6 years+? Whilst I don't mind attending court, I would want to be fairly sure of winning!

Thanks - it definitely is a PCN under the 1991 regs.

I have read that a PCN cannot refer to a date of 'offence' (as it is not an offence but a contravention) but what about if a PCN states an 'Offence Code'? It does state in words my contravention (i.e. Parked in a restricted street during prescribed hours) and does describe it as a contravention. Lower down it just says 'Offence Code: 01' I'm assuming they shouldn't refer to it as an offence code, but as this is extra information, would it invalidate the PCN?
