A disagreement over the interpretation of European law on grants and contracts has led Navca to stop using training organisation Tendering for Care.
The local umbrella body said that Tendering for Care director Janet Roberts was giving out "the wrong messages" in seminars for Navca members by claiming that grants above £20,000 were not allowed because they had, by law, to be put out to tender.
"Janet did some excellent training for Navca on competitive tendering," said Curley. "But we think she is wrong to suggest now that grant funding is no longer possible above £20,000 because of European competition law and funding regulations." But Roberts denied she had claimed that grants above £20,000 were not allowed, and said she had not had any dialogue with Navca since January.
"We have not been asked to change the way in which we address grant funding," she said.
Curley said that Navca would not use Roberts while she was in "fundamental disagreement" with Navca's Defending Grants campaign.
But he said if she changed her view, the organisation would work with her again. "We have to convince local councils that grants are outside the scope of the procurement regulations," he said.
Colin Roberts, company secretary at Tendering for Care, said: "We have no axes to grind. We are informing people of the current position on procurement."
