need advise on change of address in CoS

Hi,
I have recieved CoS NO FROM NHS employer,however in that everything is correct except that my address in UK was given the past address not the current address.
DOES THIS HAVE ANY IMPACT ,LIKE REFUSAL OF VISA IF I APPLY FOR THE SAME, ANY SOLUTIONS TO RECTIFY?
1- DO I HAVE TO CALL UK BORDER AGENCY & EXPLAIN BEFORE APPLYING,
2- IS IT POSSIBLE FOR THE NHS TRUST TO REAPPLY FOR THE COS NUMBER AFTER RECTIFYING THE ADDRESS ,

COULD YOU KINDLY ADVISE ON THIS

ask the sponsor to add a sponsor note to the CoS about your residential address but this should be done before you apply.
