Hi winterchild
It is impossible for us to say. Lots of people who were due to be reviewed before the pandemic have not been done. When they will be is anyone's guess. There is no obvious systematic system currently in place that is obvious to the public! They are also dealing with a backlog. So your relative may be lucky, but a form could pop through the door next week, next month or in a couple of months' time. Sorry, that we can't say.
