Planning Portal Fee Calculator (England)

If you’ve lowered a kerb, or you’re about to, without going through your council first, the short answer is this: there’s no single national “dropped kerb fine.” What you’re exposed to is a stack of separate legal risks — a Penalty Charge Notice for driving over the pavement, an enforcement notice that can force you to rip the kerb back out at your own cost, and, in the more stubborn cases, a criminal prosecution with a fine on top. Which of those lands on you depends on which law your council chooses to use, and that’s the part most guides gloss over.
