The thing is, it doesn't work well. Having lived in two CPZs, I can tell you you will be no better off, except you'll have to shell out ?100 a year for the privilege. And you'll have to keep a book of day tickets (which expire after three years), for friends and family and tradesmen who pop by, even for just 10 minutes. And you'll find yourself getting fined ?120 when you forget to re-apply for your permit, or, in our case, when it fell off the windscreen on a sunny day. And you'll find other drivers from the area will STILL park in your street, as the CPZ will cover a large area, for example the whole of SE22. Be careful what you wish for.
