The marketing shake-up comes six months after the arrival of former Procter & Gamble marketer Emma Jenkins as its new marketing director.
Albion has led brand development for the nascent business since its inception, having been appointed by O2 in May 2009 after a pitch via the AAR.
The agency’s remit has included all advertising, social media, website design and film idents for the brand, and also helped incubate the business in the Albion office, including naming the brand, which comes from the Scottish slang for mutual giving.
Jenkins confirmed the split with Albion, and thanked the agency for its "major contribution to our business".
Prior to joining Giffgaff, Jenkins had been a consultant at Brand Learning for two years and founded My Pet is Here, an online pet community business. The marketer worked at P&G for 12 years, most recently as associate director of new marketing models and ecommerce.Follow @DurraniMix
