I SORN'd the Mog on Tuesday evening and the refund arrived today so I can't fault them on their promptness. On the downside it has come in the post as a cheque. A bit of a faff under normal circumstances but it's going to be a right pain to pay a cheque into my bank in the current situation.
I'm surprised they can't do an electronic repayment direct into an account, especially if you pay by direct debit as I do.
The HSBC App lets me pay a cheque in by taking a picture of it and uploading the picture - Max £500 one cheque, £750 in cheques in one day.
I believe Barclays has something similar but not used it.
