The charity has approached AAR to help run a pitch. As Campaign went to press, AAR had already started contacting agencies with the brief and held meetings.
Sue Ryder worked with agencies – including J Walter Thompson and Agency Republic – on an ad hoc basis until 2011, when it appointed TMW to its integrated account after a pitch.
The charity also hired Code Computerlove as its digital agency in 2013 in an attempt to boost donations through its website.
A spokesman for Sue Ryder confirmed that the charity was looking for a marketing agency to work with but declined to comment further.
The organisation was formed in 1954 in Suffolk by Sue Ryder, a volunteer during the Second World War and a charity worker who was made a life peer before her death in 2000.
