The two organisations announced last month that they were in talks about CES, a charity that helps other voluntary sector organisations become more effective, merging into the NCVO.
In a statement today, the two organisations said that eight of CES’s 11 staff would transfer to the NCVO next month. The remaining three, including Sam Matthews, chief executive of CES, would provide consultancy services to the NCVO after the merger was complete, the NCVO said.
One further staff member who would have transferred to the NCVO has got a new job since the plan for CES to become part of the umbrella body was announced, an NCVO spokesman said.
Jenny Field, one of CES’s trustees, will join the NCVO board.
Talks between the two organisations began in July after CES invited other organisations to set out proposals for how they could help secure a strong future for the charity.
CES’s income has fallen from £2m in 2008 to slightly more than £1m in 2013, and it has made a loss in each of the past six years. An NCVO spokesman said last month that CES was, however, expected to make a surplus in 2014.
CES runs the PQASSO performance assessment tool, which has been used by more than 14,000 organisations.
Richard Williams, director of enterprise at the NCVO, said: "I’m very much looking forward to welcoming our new colleagues. With their knowledge and expertise we will be able to do more than ever to support our members and help them make the biggest difference."
