Subway UK and Ireland has appointed Above & Beyond as its retained creative agency as it looks for a "fresh set of eyes" to help the brand drive traffic and boost market share.
The win follows a competitive three-way pitch run by AAR. Subway worked with McCann London for 10 years, but called time on the relationship in April.
Colin Hughes, country director at Subway, said: "We have had a very positive and effective relationship with the McCann team for more than 10 years, during which time they have produced some excellent work for us.
"We are, however, operating in a constantly changing marketplace and feel that we will now benefit from a fresh set of eyes on our brand and target audiences."
McCann continues to work on Subway's European business, which it picked up in 2017. MediaCom handles the brand's media planning and buying.
