ACEVO is a strategic partner of the Cabinet Office's Office for Civil Society, and has been involved in the government's numerous task forces and working groups. Together with New Philanthropy Capital, ACEVO developed and pioneered the concept of Full Cost Recovery, which states that third sector organisations should cost their work robustly, and that the funding they receive from government should be sustainable. ACEVO has been criticised by other voluntary sector organisations for taking political stance in favour of charities assisting with the privatisation of public services such as healthcare and prisons. The National Council for Voluntary Organisations criticised a 2005 ACEVO report warning it could "warp public perception of the role of the sector".
