Parking increase getting approval (6)
I believe the answer is:
praise
'approval' is the definition.
(praise is a kind of approval)
'parking increase getting' is the wordplay.
'parking' becomes 'p'.
'increase' becomes 'raise' (raising is a kind of increasing).
'getting' is a charade indicator (letters next to each other).
'p'+'raise'='PRAISE'
(Other definitions for praise that I've seen before include "flatter" , "Eulogise" , "Aspire (anag)" , "plaudit" , "Express approval and admiration" .)
