House of Lords Act 1999 in the context of "Lords Reform"

The House of Lords is the upper house of the Parliament of the United Kingdom. Like the lower house, the House of Commons, it meets in the Palace of Westminster in London, England. One of the oldest extant institutions in the world, its origins lie in the early 11th century and the emergence of bicameralism in the 13th century.

In contrast to the House of Commons, membership of the Lords is not generally acquired by election. Most members are appointed for life, on either a political or non-political basis. Hereditary membership was limited in 1999 to 92 excepted hereditary peers: 90 elected through internal by-elections, plus the Earl Marshal and the Lord Great Chamberlain as members ex officio, the sole two officers to directly inherit their seats. The House of Lords also includes up to 26 archbishops and bishops of the Church of England, known as Lords Spiritual. Since 2014, membership may be voluntarily relinquished or terminated upon expulsion.

The Peerage of the United Kingdom is one of the five peerages in the United Kingdom. It comprises most peerages created in the United Kingdom of Great Britain and Ireland after the Acts of Union in 1801, when it replaced the Peerage of Great Britain. New peers continued to be created in the Peerage of Ireland until 1898 (the last creation was the Barony of Curzon of Kedleston).

The House of Lords Act 1999 reformed the House of Lords. Until then, all peers of the United Kingdom were automatically members of the House of Lords. However, from that date, most of the hereditary peers ceased to be members, whereas the life peers retained their seats. All hereditary peers of the first creation (i.e. those for whom a peerage was originally created, as opposed to those who inherited a peerage), and all surviving hereditary peers who had served as Leader of the House of Lords, were offered a life peerage to allow them to continue to sit in the House, should they wish.

Under the reforms of the House of Lords Act 1999, the majority of hereditary peers lost the right to sit as members of the House of Lords, the upper house of the Parliament of the United Kingdom. Section 2 of the Act, however, provides an exception from this general exclusion of membership for up to 92 hereditary peers: 90 to be elected by the House, as well as the holders of two royal offices, the Earl Marshal and the Lord Great Chamberlain, who sit as ex officio members. The initial cohort of excepted hereditary peers were elected in the 1999 House of Lords elections. Between 1999 and November 2002, vacancies among this group were filled by runners-up in the 1999 election. Since then, by-elections to the House of Lords have filled vacancies.

Candidature for both the 1999 elections and subsequent by-elections is restricted to peers in the Peerages of England, Scotland, Great Britain and the United Kingdom. Peers in the Peerage of Ireland are only eligible for election if they hold a title in one of the other peerages, but if successful may use their Irish peerage title as a member of the House. The electorates are either the whole membership of the House of Lords (including life peers), or a party group of sitting hereditary peers. A standing order of the House, approved prior to the commencement of the House of Lords Act 1999, mandates that the 90 elected hereditary peers consist of:

By-elections to the House of Lords occur when vacancies arise among seats assigned to hereditary peers due to death, resignation, or disqualification. Candidates for these by-elections are limited to holders of hereditary peerages, and their electorates are made up of sitting Lords; in most cases the electorate are those sitting hereditary peers of the same party affiliation as the departed peer. Following the enactment 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. The Earl Marshal and the Lord Great Chamberlain were entitled to sit ex officio; the remaining ninety were elected by all the hereditary peers before the passing of the reform.

Before the passing of the 1999 Act, the Lords approved a Standing Order stating that the remaining hereditary peers shall consist of:

The hereditary peers in the United Kingdom and the Republic of Ireland form part of the peerage in the United Kingdom. As of October 2025, there are 799 hereditary peers: 29 dukes (including five royal dukes, of which the Duke of Edinburgh is a life peerage, the holder being a hereditary earl), 34 marquesses, 189 earls, 108 viscounts, and 439 barons (not counting subsidiary titles).

As a result of the Peerage Act 1963, all peers except those in the peerage of Ireland were entitled to sit in the House of Lords. Since the House of Lords Act 1999 came into force only 92 hereditary peers, elected from all hereditary peers, are permitted to do so, unless they are also life peers. Peers are called to the House of Lords with a writ of summons.

The Peerage of England comprises all peerages created in the Kingdom of England before the Act of Union in 1707. From that year, the Peerages of England and Scotland were closed to new creations, and new peers were created in a single Peerage of Great Britain. There are five peerages in the United Kingdom in total.English Peeresses obtained their first seats in the House of Lords under the Peerage Act 1963 from which date until the passage of the House of Lords Act 1999 all Peers of England could sit in the House of Lords.

As of September 2025, there are 93 English peers: 11 dukes (including one royal duke), one marquess, 26 earls, three viscounts and 52 barons (counting peers with a higher title in one of other peerages).

The Peerage of Great Britain comprises all extant peerages created in the Kingdom of Great Britain between the Acts of Union 1707 and the Acts of Union 1800. It replaced the Peerage of England and the Peerage of Scotland, but was itself replaced by the Peerage of the United Kingdom in 1801.

The ranks of the Peerage of Great Britain are Duke, Marquess, Earl, Viscount and Baron. Until the passage of the House of Lords Act 1999, all peers of Great Britain could sit in the House of Lords.

Elections of the excepted hereditary peers were held in October and November 1999, before the House of Lords Act 1999 excluded most hereditary peers from the membership of the House of Lords allowing Earl Marshal, Lord Great Chamberlain and 90 others to remain in the House. Before the passing of the 1999 Act, the Lords approved a Standing Order stating that those 90 would consist of:

• 15 peers to be elected by the whole House
• 75 peers elected among and within party groupings:
  • 2 to be elected by the Labour hereditary peers
  • 42 to be elected by the Conservative hereditary peers
  • 3 to be elected by the Liberal Democrat hereditary peers
  • 28 to be elected by the Crossbench hereditary peers

The elections used a version of plurality block voting: voters were required to rank candidates in order of preference for the number of seats available, with the candidates receiving the greatest number of votes, without regard to the ranking on the ballots, declared elected. Preference order was only considered in the cases of ties.
