The win sees Maiden wrest the business from incumbent Clear Channel, which has held the work for the past five years, and beat rival JC Decaux in the pitch process, which was called in December.
Under the terms of the contract, Maiden will invest up to £1m introducing new sites across the city, including 96-sheet and scrolling 48-sheet panels to its existing, mostly 48-sheet sites.
The win follows the news last month that revenues at the outdoor advertising firm for March and April were down on last year as it was hit by the negative impact of the war in Iraq. Despite the impact of the war, Maiden said early signs in 2003 were encouraging, with a record performance in group sales in the first quarter.
Ron Zeghibe, chief executive of Maiden, said: "This contract, which was won against a strong and highly respected international incumbent, will strengthen our national network and number one position in large format sites across the UK. It will give advertisers access to the second largest advertising market in the UK."
In all, Maiden will handle advertising for as many as 200 outdoor panels. It will take over the business in the autumn.
