Seat has signed its biggest ever fleet deal with the announcement that it has bagged a 500-car three-year agreement with British Gas.

The 500 Leon models will be the first of the new 99g/km Ecomotive versions into the country, with deliveries expected to be complete by March.

“Obviously the tam’s efforts in securing this business represent a major milestone for us,” said Seat UK head of fleet and business sales Nick Andrews. “But this is just the beginning, our aim is to make Seat a fleet manufacturer of choice and we will be working hard to achieve that ambitious target over the months and years ahead.”

British Gas fleet manager Colin Marriott said: “Seat has taken an industry-leading approach; innovative, flexible and way ahead of anyone else in the tender process.”
