Overview

The House of Lords is the upper chamber of the legislature of the United Kingdom, sitting in London, the country's capital city. Together with the House of Commons it forms the two‑house body that makes laws and holds the government to account within the parliament.

Its role is principally to examine, amend and delay legislation rather than to initiate government policy. Most members are appointed as life peers for their expertise or public service; a limited number of hereditary peers remain after reform, and 26 bishops of the Church of England sit as Lords Spiritual. Unlike the Commons, the Lords is not generally elected.

Composition and membership

Membership is a mixture of life peers appointed on ministerial advice or by independent vetting bodies, a small cohort of hereditary peers elected internally by their own number, and senior clergy. Peers do not represent districts or constituencies: they contribute specialist knowledge from politics, law, business, academia, the arts and civil society.

Powers and functions

The Lords acts as a revising chamber. It reviews bills originating in either house, proposes amendments, scrutinises secondary legislation and conducts detailed committee inquiries into public policy and administration. While it can delay non‑financial bills and force further consideration, constitutional conventions and statute give the elected Commons primacy on key matters such as money bills.

History and reform

Tracing its roots to medieval councils of nobles and clergy, the House of Lords transformed over centuries from a feudal assembly to a modern parliamentary chamber. Major reforms in the late 20th century removed most hereditary peers and judicial functions were transferred to the Supreme Court. Debate about further reform—balancing democratic legitimacy, expertise and effectiveness—continues.

Role and notable facts

  • Function: A forum for detailed legislative scrutiny and expert debate.
  • Limits: The Commons retains final authority on financial matters and overall government mandate.
  • Operation: Much of the Lords' work is done in committee and through amendment rather than raw voting power.
  • Conventions: Practice such as the Salisbury Convention affects how the chamber deals with manifesto commitments.
