You need to pay the fine within 28 days of it being issued. If you don't you could be taken to court, fined up to £1,000 (and court costs) and get a criminal record.
Pay early. Pay less.
If you're paying the fine in the first 21 days of getting it, pay £60.
Otherwise, pay £120.
See what to do if you lost the fine or haven't paid it within 28 days.
