Documents sent by First Class post on 10th March, so assume received 11th. Documents marked as received on 25th March, therefore 13 working days to be received (I believe they work Saturdays too). Wish I’d gone special delivery but didn’t realise how bad it is there! Hope this puts someone’s mind at rest if you’re checking every day like me.
Also, probably not worth logging in to check, as they email you as soon as received. Save yourself the disappointment of seeing ‘SEND US YOUR DOCUMENTS’. They even had the cheek to remind me to send them yesterday…
