Code of Conduct and Associated Rules and Guidance for Members of the Senedd

The purpose of the Code of Conduct is to uphold the reputation of the Senedd. It provides the openness and accountability necessary to reinforce public confidence in the Members of the Senedd regarding the way in which they discharge their important public duties and responsibilities.

This Code applies to all Members of the Senedd. Members must comply with it. Further rules on the conduct of Senedd business, including Standing Orders and the Presiding Officer's guidance, can be found here.

The Senedd is committed to dealing effectively with any concerns or complaints. Should you have any concerns about a Member's conduct or wish to make a complaint, please contact the Standards Commissioner.

On 18 March 2026, the motion to approve the Code of Conduct on the Standards of Conduct for Members of the Senedd was agreed by the Senedd, to come into force for the beginning of the Seventh Senedd. Further information about the development of the new code is set out in a news article.
