Following the passing of the House of Lords Act 1999, the number of hereditary peers entitled to sit in the House of Lords was reduced to ninety-two. Ninety of the first ninety-two were elected by all the hereditary peers before the passing of the reform. Since November 2002, by-elections have been held to fill vacancies left by deaths of those peers. Since the passing of the House of Lords Reform Act 2014, by-elections have also been held to fill vacancies left by the resignation of those peers.
