Town spent £779,739 on agents’ fees between February 2nd 2021 and January 31st this year, almost double the £341,622 paid out during the previous year.
Only Sheffield Wednesday, £796,224, paid out more among the other League One clubs. Town's total is higher than six current Championship sides over the period, Barnsley, Blackpool, Derby, Hull City, Luton and Peterborough.
The significant increase in spending on agents is little surprise given the turnaround in playing staff over the summer.
As well as new permanent and loan signings, the £779,739 includes the fees relating to new contracts for the likes of Janoi Donacien, Idris El Mizouni and youngsters Harley Curtis and Ola Bello.
The FA has been required to publish clubs' spending on intermediaries by FIFA regulations since April 2015.
