The steering group for the code of good governance is asking whether there is a need for a new code specifically for larger or more complex charities.
Good Governance: A Code for the Voluntary and Community Sector, which sets out six key principles for a good board, was first published in 2005 and updated in 2010.
The steering group that oversees the codes has put out a call for comments on whether the main governance challenges faced by larger or more complex organisations are adequately addressed by the code, and is asking for feedback to be given online.
There is no specific deadline for responses, but Lindsay Driscoll, chair of the group, said: "We are hoping to conclude the consultation in the autumn and the work on this will be taken forward by the new chair." She is planning to step down once a successor has been appointed.
The code is backed by a funding group made up of the charity leaders group Acevo, the Institute of Chartered Secretaries and Administrators, the National Council for Voluntary Organisations, the Small Charities Coalition and the Wales Council for Voluntary Action.
Principles established in the code include being open and accountable, understanding the role of trustees and behaving with integrity.
A separate version for smaller organisations was published in 2011.
A 2009 consultation, which informed the 2010 version of the code, found that a quarter of respondents had never heard of the code.
Driscoll, who has chaired the group for six years, said: "I decided to stand down towards the end of last year because I thought it was time for a change of chair in line with good governance practice."
The recruitment process for a new chair began in March and was led by the NCVO. Applications closed on 14 April and interviews are taking place next month. The new chair will be appointed for a three-year term and will commit two days a month.
