Unfortunately its anybodys guess.
There are lots of things that can throw spanners in the works our application was held up for 3 months when the medicals did not go as planned.
Some people get CO's quite quickly and others seem to have to wait.
The wait times dont seem as bad since the new system was introduced back in September but you say there is now a back log.
We were advised at the beginningit can take anything from 9 to 15 months but that is with the old system.
In this visa game its all about patience and a long time waiting
good luck
