OK, it's leased, so they had 28 days to send the first PCN to the lease company, who then had 28 days to reply. Then on the assumption they submitted reps that were accepted, another 28 days to send out a second PCN to you. Assuming about 10 days for council admin, that doesn't add up to 18 months. So where would the delay be ? The council has to first get the name and address of the V5C holder from the DVLA using a messaging system. So maybe this is it. Certainly when they get your name and address from the lease company, they can act straightaway.
