The House of Lords is the second chamber of the UK Parliament, an unelected body that scrutinises and revises legislation. Here is its role, who sits in it, and how its powers differ from the elected House of Commons.
The House of Lords is one of the more puzzling features of British democracy: a powerful part of Parliament whose members nobody votes for. It is often in the news — revising a controversial bill, clashing with the government, or at the centre of debates about reform — yet its actual role is widely misunderstood. Here is a clear explainer of what the House of Lords is, who sits in it, what it does, and how its powers compare with the elected House of Commons.
The House of Lords is the second chamber of the UK Parliament, working alongside the elected House of Commons to make laws and hold the government to account. Parliament is bicameral, meaning it has two chambers, and the Lords is sometimes called the "upper house", though in practice it is the less powerful of the two.
Its defining feature is that its members are not elected. They are appointed, and they are known as peers or members of the House of Lords. According to Parliament's own description, the Lords' central purpose is to act as a revising and scrutinising chamber: to examine the work of the government and the laws it proposes, bringing a wide range of expertise to bear, while ultimately deferring to the elected Commons on the biggest decisions.
This combination — real influence over legislation, but no electoral mandate — is what makes the Lords both useful and controversial.
Membership of the House of Lords comes from a few distinct routes, and unlike the 650 elected seats of the Commons, the chamber has no fixed size.
| Group | How they get there |
|---|---|
| Life peers | Appointed for their lifetime, usually for experience or public service |
| Bishops | A number of senior Church of England bishops, known as the Lords Spiritual |
| Hereditary peers | A limited number remain after reforms reduced their numbers |
Many peers sit as crossbenchers, taking no party whip, which gives the Lords a different character from the sharply party-divided Commons. Peers often bring direct experience from medicine, law, science, business, the armed forces, the arts and public administration, and this expertise is frequently cited as the chamber's main justification.
The Lords has three principal functions, all of which complement rather than duplicate the elected chamber.
The Lords is best understood as a "revising chamber". Its strength is asking the government to reconsider — sending amendments back to the Commons and inviting a rethink — rather than imposing its own will against the elected House.
This work runs in parallel with the elected chamber, where the day-to-day politics of what an MP does and the outcome of a general election determine who forms the government in the first place.
The crucial point is that the House of Lords is subordinate to the House of Commons, and several conventions and laws keep it that way.
So while the Lords can be a thorn in a government's side — and frequently is, sending bills back with amendments — the final word rests with the Commons. The relationship is one of scrutiny and challenge, not rivalry for supremacy.
Because the Lords is unelected, it is a perennial subject of reform proposals. Supporters argue that appointment brings independence and expertise that an elected chamber might lack, and that its lack of a mandate appropriately limits its power. Critics argue that an unelected body has no place in a modern democracy, point to its large and growing size, and call for an elected or partly elected second chamber. Successive governments have proposed changes, but wholesale reform has repeatedly stalled. For the authoritative, up-to-date position on the chamber's composition and powers, the definitive source is Parliament itself.
The House of Lords is the second chamber of the UK Parliament: an unelected body of life peers, bishops and a few hereditary peers whose main job is to scrutinise and revise legislation and hold the government to account. It brings expertise and independence, especially through its crossbenchers and committees, but it is deliberately the weaker chamber. It cannot meaningfully amend money bills, by convention it does not block the government's manifesto plans, and under the Parliament Acts the elected Commons can ultimately have its way. The Lords improves and challenges laws — but the final decision rests with the people's elected representatives.
