I'd revise about getting registered at the bank (9)
I believe the answer is:
riverside
'the bank' is the definition.
(riverside is a kind of bank)
'i'd revise about getting registered' is the wordplay.
'about' indicates an anagram.
'getting' indicates putting letters inside.
'registered' becomes 'R' (abbreviation, as in registered trademark).
'id'+'revise'='idrevise'
'idrevise' anagrammed gives 'riveside'.
'riveside' enclosing 'r' is 'RIVERSIDE'.
'at' acts as a link.
(Other definitions for riverside that I've seen before include "Bank" , "Area along, say, the Thames" .)
