Scottish Power is conducting a review of its above-the-line advertising account, believed to be worth £4m.
The business is held by Glasgow-based agency The Bridge, which first won the work in 2001. The Bridge's contract term has ended, prompting the review, according to a spokesman for Scottish Power. The review is being handled by agency intermediary creativebrief.
The spokesman says a shortlist of agencies, including The Bridge, has been drawn up. He adds: "We have an excellent relationship with the agency." He declined to name any other shop on the shortlist, but says: "We are approaching the review with an open mind."
