The category is open to leasing businesses from small brokerages to significant independent leasing operations.
Entrants will complete an awards submission which asks for details of how the entrant ensures competitive offers and customer satisfaction, how the operation has grown, and what sets it apart from its rivals.
Finalists will be revealed in April and the winner will receive their trophy at the AM Awards ceremony on May 12 at London’s Park Plaza Westminster Hotel.
AM editor Tim Rose said: "The deadline is less than a month away now.
"After the surprises that 2021 brought to our industry we're expecting to see some really exciting entries, and it will be fantastic to see hundreds of you join us at our new venue, the Park Plaza Westminster Hotel in London."
