They are planning to meet in November to talk about ways of improving relationships between small and large voluntary sector organisations so they can better face up to the challenges of government cuts and the recession.
Speaking at the Community Links Bromley annual general meeting yesterday, Joe Irvin, chief executive of Navca, said voluntary sector organisations must work together more closely during difficult times.
"This is a message for Navca as well," he said. "We need to work together better with other national umbrella organisations, something I have made a priority since becoming chief executive in January.
"We are also talking with other national umbrella organisations to see how we can give the best possible support to the voluntary sector. One example of this is that we are meeting with Acevo to explore how we can break down barriers between big and small charities."
Sir Stephen Bubb, head of the chief executives body Acevo, will today tell members of the Devon Consortium of Voluntary and Community Organisations that Acevo has developed a toolkit to support consortia working and that it intended to increase the support it offered in this area.
"Acevo has a particular strength as a national body of leaders, but we too need to work in partnership," he will say. "So I am committed to developing the links and connections we need with Navca as the organisation that represents the CVS movement nationally.
"The diversity of our sector is one of its strengths. We need to harness that strength rather than concentrating on our differences and our divisions."
