Lloyd Northover has been appointed in preparation for the college's relocation to a new £50m campus at Greenwich Peninsula.
It will conduct a brand audit and perception study among stakeholders, including students, alumni, current and past governors, as well as business partners.
The results will be used to evaluate the brand positioning of Ravensbourne, measure the effectiveness of its messaging communication compared to other colleges, and identify perceived strengths and weaknesses.
The findings, to be delivered in July, will form the basis of a brand strategy to be developed and implemented during later stages of the project.
Ravensbourne's new campus, designed by Foreign Office Architects, will feature a layout and work spaces that deliberately simulate the environment and working practices experienced in the industry.
Jim Bodoh, director of strategy at Lloyd Northover, said: "The way Ravensbourne is approaching this branding programme is far more thorough than any other college of its size that we have ever worked with. They are doing it very strategically and in a way that serves as a role model to others."
Jill Hogan, Ravensbourne's head of marketing and communications, said: "Lloyd Northover has really impressed us with their understanding of what we are trying to achieve at Ravensbourne and the challenges our sector is facing."
The new building is expected to be completed in April 2010.
