You need grounds to challenge a parking fine, not knowing about the rules or not being able to afford a fine are not grounds.
There are a number of organisations which can issue motoring offence :
1. the council – in which can go to their website to find guidance on the process
2. the police – specific offences are issued by the police under criminal law and are called Fixed Penalty Notices.
3. Transport for London for red route contraventions – go to their website
4. Private companies for private car park, such as a supermarket or shopping centre contraventions – you will need to find out the company details to find out the procedure
The appeal rules depend on your ticket type so ensure you read the right section below. We’ve included info for civil ticket appeals, criminal ticket appeals and police ticket appeals.
Your appeal will largely involve writing up to three separate letters, though the general content will usually be similar in each of them. So keep a copy of the first one safe, and just alter the introduction and any other points as necessary.
