By-elections to the House of Lords

Home Page | By-elections to the House of Lords

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:

  • 2 peers to be elected by the Labour hereditary peers
  • 42 peers to be elected by the Conservative hereditary peers
  • 3 peers to be elected by the Liberal Democrat hereditary peers
  • 28 peers to be elected by the Crossbench hereditary peers
  • 15 peers to be elected by the whole House
    • By convention, whole-House elections elect members of the same affiliation as the departed peer.
  • The holders of the offices of Earl Marshal and Lord Great Chamberlain to be ex officio members.
    • The current holder of the office of Lord Great Chamberlain was previously elected to the House of Lords in a by-election.

Prior to November 2002, vacancies were automatically filled by the highest performing unsuccessful candidate in the 1999 House of Lords election that elected the departed peer.

Elections are normally required to be held within three months of a vacancy occurring, but until the end of 2024–2026 parliamentary session, elections must be held within 36 months—in practice suspending by-elections whilst the role of hereditary peers in the Lords is debated (see House of Lords (Hereditary Peers) Bill).

The elections take place under the Alternative Vote system for elections to individual vacancies and the Single Transferrable Vote for elections to fill multiple vacancies. All those on the Register of Hereditary Peers are eligible to stand, but only sitting (the "excepted") hereditary peers of the group in question may vote for the seats reserved for a single parliamentary group. This can result in very small electorates, such as only three voters in the 2003 election of Lord Grantchester. For the 15 peers elected by the whole House, life peers may also vote.

As of September 2023, there have been 18 by-elections among Conservative peers; 19 by-elections among Crossbench peers; 2 among Liberal Democrat peers; and 2 among Labour peers. In addition, there have been 14 by-elections by the whole House.

2020s

Normally, by-elections must be held within three months of a vacancy occurring, but in response to the COVID-19 pandemic the House resolved in March 2020 to suspend any by-elections. Although this initial suspension was only until 8 September 2020, successive further motions extended this arrangement. Ultimately by-elections resumed in June 2021 with multiple elections held to fill six vacancies.

Upcoming by-elections

Currently, there are five vacancies among the elected hereditary peers:

  • The Earl of Sandwich (Crossbench), retired 20 May 2024.
  • The Lord Willoughby de Broke (non-affiliated, elected as Conservative), membership removed due to non-attendance 9 July 2024.
  • The Viscount Craigavon (Crossbench), died 31 March 2025.
  • The Viscount Waverley (Crossbench), retired 23 June 2025.
  • The Lord Aberdare (Crossbench), retired 31 August 2025.

Ordinarily, by-elections to fill vancancies would have been required within three months. However, on 25 July 2024, in anticipation of imminent legislative debates on the abolition of the right of hereditary peers to sit in the Lords (see below), and reflecting views that "ongoing by-elections during the parliamentary consideration of a Bill would be deeply undesirable in this context", the House of Lords passed a motion to extend the deadline for holding a by-election to 18 months. On 22 October 2025, the House passed a motion to further extend the deadline to 36 months for the remainder of the 2024–2026 parliamentary session.

In September 2024 the newly-elected Labour government introduced the House of Lords (Hereditary Peers) Bill. If enacted this would remove the right of the remaining hereditary peers to sit and vote in the House of Lords.

Scottish and Irish by-elections

From the 1707 Act of Union to the passing of the Peerage Act 1963, peers in the Peerage of Scotland elected sixteen representative peers to sit in the House of Lords. Unlike Irish peers, however, Scottish representative peers only sat for the duration of one parliament before facing re-election. By-elections were held in the Palace of Holyroodhouse to replace deceased peers. After the passing of the Peerage Act 1963, all Scottish peers were entitled to sit in the House of Lords and the election procedure was abolished.

The last Scottish representative peer by-election took place in 1959, when the Duke of Atholl was elected in place of the late Lord Sinclair.

Also, from the 1801 Act of Union to Irish independence, 28 Irish representative peers were elected from and by the Peerage of Ireland to sit in the British House of Lords. Like current hereditary peers, these representative peers sat for life terms and deceased peers were replaced in by-elections. Unlike modern hereditary peer by-elections, all peers in the Peerage of Ireland, even those who did not sit in the House of Lords, were entitled to vote. Upon the creation of the Irish Free State, the offices required to officiate these by-elections were abolished and thus no more were held, but those peers already elected kept their seats for the remainder of their lives. The last to sit in the Lords was Francis Needham, 4th Earl of Kilmorey, who died in 1961.
