The fast-food chain, a joint venture between Whitbread and Yum! Brands, is in the early stages of contacting agencies. The account has been held by AMV since 1998.
Pizza Hut has already reviewed its media account this year, which moved from the AMV-aligned PHD to Starcom Motive in June. It is also looking at its direct marketing arrangements, handled by the AMV sister agency Minerva. A DM pitch is scheduled to be held in two weeks' time.
The review is being overseen by Pizza Hut's director of retail marketing, Simon Wallis. Wallis reports to the marketing director, Martin Pugh, who joined the company earlier this year from Safeway, after the supermarket chain was taken over by Morrisons.
A Pizza Hut spokeswoman said: "As with all major organisations, it is our policy to request a competitive pitch of our UK advertising business every few years to ensure continued media excellence."
The company signed up earlier this month as the headline sponsor of Channel 4's high-profile The Simpsons for the next year.
