The agency's public affairs team is assessing how the organisation's partners view BW and will recommend how this can be improved.
Stakeholders include VisitLondon, the London Development Agency and private sector organisations.
Four associate Jim Dickson said: 'British Waterways wants to know how it can work better with its stakeholders, politicians and public, policy makers, and this project will see how they can form closer relations.'
The firm has called in Four after a review of its national PA account, begun last summer (PRWeek, 23 July 2004).
BW is no longer using Citigate Public Affairs for the national account, having decided to take public affairs work in-house. Four has been hired on a project basis for an initial six months.
BW London comms manager Edward Fox said: 'The Government is encouraging us to work with public and private bodies more, and we are already working with bodies such as Transport for London, trying to encourage more commercial freight on the waterways.'
