I thank the Rt Rev David Walker for expressing his views on the revised National Housing Federation code of governance ("Experience is golden", 30 January, page 21) so publicly.

I hope they will act as a catalyst for a full and frank debate.

The consultation document takes account of the deliberations and conclusions of the Higgs Report on the role and effectiveness of non-executive directors in the corporate sector and the Smith review into audit committees, both of which are recognised as good practice in their own right.

Some organisations in the voluntary and charity sectors are already working with fixed terms for board members, supported by the National Council for Voluntary Organisations. Some housing associations have being doing the same for many years.

In recommending a fixed term of nine years for board members, we have aimed to ensure a balance of continuity and familiarity with the association's business with the need to continuously review and challenge.

This can be greatly assisted by renewing a proportion of a board's membership on a regular basis. These new members will bring a fresh approach and a new perspective, which can only be healthy.

In addition, the renewal of boards on a regular basis allows the sector to meet equality and diversity objectives.

The code is meant to provide guidance.

It clearly states that its recommendations may not apply to all. It is up to organisations to either "comply or explain". In particular, we would expect associations to phase in any recommendations they wish to adopt.

People who have served a full term also have the ability to consider returning to the same association as board members, after a year's break.

We look forward to hearing from NHF members and stakeholders to enable us to improve our current code of governance and to ensure we continue to provide best practice and are recognised as leaders in good governance.
