None, just a straight forward renewal.
I spoke to them on the phone, this is what they said.
10 to 11 weeks was the present waiting time, ( application went in online on the 6th August ).
If the licence was not received after 10 weeks, I was told to ring back, they would then investigate the whereabouts of the licence with Royal mail.
By that, I assumed that renewal of the licence was dependant on them receiving it.
I sent the licence, signed for, I have the receipt, and a scrawled online signature.
Make of what they said, as you will.
