List of elected hereditary peers under the House of Lords Act 1999

This is a list of hereditary peers elected to serve in the House of Lords under the provisions of the House of Lords Act 1999 and the Standing Orders of the House of Lords. Aside from the Earl Marshal (the Duke of Norfolk) and the peer carrying out the office of Lord Great Chamberlain (currently the Marquess of Cholmondeley), ninety hereditary peers who are not also life peers must be elected by other peers to sit in the Lords. These ninety are either elected by all the sitting members of the Lords to be one of fifteen hereditary deputy speakers, or are one of the remaining seventy-five, elected by one of the political groups of hereditary peers sitting in the House, including the crossbenchers.
