The Football League have released details of payments to agents in the past season.
The Bulls spent £11,470 on agents during 51 'transactions' - including 21 player loans and 12 cancelled contracts. League Two sides spent just over £1million with nearly half of it, £448,506, being spent by Swindon Town.
Their spend also beat every League One side and nine of the Championship clubs and was double what League Two sides spent in their entirety the season before.
Five sides spent nothing on agents, down from eight last season. Top spenders in the FL were West Ham, who spent £4.3million on agents - nearly three times more than any of their rivals.
