Given the "Wild West" nature of this market, the parking companies rarely apply for planning permission for their ANPR installations.
They operated a model of retrospective planning. So once they get the go ahead from the client, the system goes in and then if there was any "noise" they file a retrospective planning order. This was simply to save on costs and delays in getting parking charge income. And it worked.
The costs of getting retrospective planning, is more than covered by the revenue from getting in the ANPR systems early as people get caught out when changes are introduced.
What can you do.
Check with the council if planning permission has been requested.
Does it change the parking.
Unlikely save for the point that if your ticket was issued in the first two weeks of an installation there is usually a "grace period" to allow drivers to adjust to the new terms.
