There is no fixed timescale for an MR or an appeal.
Typically MRs take 5-8 weeks, they can be as short as a couple of weeks and they can stretch to 2-3 months.
You can't appeal until an MR has been completed, we are currently seeing appeals take 2-2 months depending on the region, 6 months at the outside.
