Instruction to bank (8,5)
I believe the answer is:
standing order
'instruction to bank' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for standing order that I've seen before include "Instruction to bank for payment at regular intervals" , "Arrangement made with bank to pay" , "rise!" , "gets you on your feet!" , "Instruction for bank to make regular payments" .)
