In my personal experience I sent a document to the Bootle office at the beginning of April and it was recorded as received on 27th April and has yet to be uploaded to the system for the assessor to check against my application. I phoned the advice line and was advised that the uploading / scanning of documents can take three further weeks – my three ‘further’ weeks are up tomorrow so it will be interesting to see if my document is on the system.
Hopefully your documents will be recorded in a shorter timeframe at Durham.
