One demanding payment for horse (7)

I believe the answer is:

charger

I believe this clue is a double definition.

'one demanding payment' is the first definition.
(somebody who charges a fee)

'for horse' is the second definition.
(charger is a kind of horse)

(Other definitions for charger that I've seen before include "A large dish or a cavalry horse" , "One may provide juice" , "Horse; flat dish" , "Horse - plate" , "Battle horse" .)

I've seen this clue in The Sun and The Times.
