Err - as many as the locations in which you have a parking violation? EG. Potentially unlimited if you move around Wandsworth all day and don’t pay for your parking in any place.
Or if you mean your car has not moved and you have accidentally parked in contravention if the rules - eg. Your resident permit expired when you are on holiday - then the limit is one ticket oer period covered by the parking restriction in the 24 hour period . SO - if the location is residents only 0930-10.30 and 1430- 1630, then you would get two tickets per day, every day until you get your new permit or activate
(But in this case I have successfully appealed and had cancelled all but the first days ticket on the grounds that if you are not in the country and at home then it is not reasonable to fine for the subsequent days since you had no knowledge or opportunity to rectify the problem).
