Background

The House of Lords is the upper chamber of the UK Parliament, composed of approximately 800 life peers, 26 Lords Spiritual (Church of England bishops), and 92 hereditary peers retained under the 1999 reform. Unlike the elected House of Commons, the Lords exercises its legislative role primarily through detailed scrutiny and amendment rather than the power of veto: the Parliament Acts of 1911 and 1949 limit the Lords to delaying non-money bills by one year, and by convention (the Salisbury Convention) the chamber does not obstruct manifesto commitments. In June 2026 the Cyber Security and Resilience Bill passed its Commons third reading and was sent to the Lords for the next stage of scrutiny.

The Lords performs functions distinct from the Commons: it provides extended committee scrutiny of complex technical legislation, a function especially significant for bills covering emerging technology and regulated industries where specialist expertise among peers is concentrated. The chamber's crossbench membership (peers with no party affiliation, often drawn from scientific, legal, and business backgrounds) means government bills regularly face substantive revision. Industry lobbying on legislative detail, including fine ceilings and scope definitions, is typically most effective at the Lords stage.

Beyond legislation, the Lords includes select committees that investigate policy areas independently of the government's timetable. The Lords Science and Technology Committee and the Lords Communications and Digital Committee both cover the territory of cybersecurity and digital regulation, and their reports carry weight with ministers and regulators even when they do not result in legislative amendment.

Common Questions

What happens to the Cyber Security and Resilience Bill in the House of Lords?

After passing its Commons third reading in June 2026, the bill moves to the Lords for committee and report stages, where peers (including industry experts and former regulators) can propose and vote on amendments before it returns to the Commons.Source: event

How many members does the House of Lords have?

Approximately 800 life peers sit alongside 92 hereditary peers and 26 Lords Spiritual (Church of England bishops), making it one of the largest parliamentary chambers in the world.

What powers does the House of Lords have over legislation?

The Lords can scrutinise and amend bills and delay non-money bills by up to one year, but cannot permanently block legislation. The Parliament Acts 1911 and 1949 set these limits; the Salisbury Convention prevents the Lords from blocking manifesto commitments.

Can the House of Lords block a bill it disagrees with?

No. The Lords can delay a bill and force the Commons to reconsider amendments, but under the Parliament Acts the Commons can pass the bill without Lords approval if the Lords refuses it across two consecutive sessions.

How the World Sees Them

European Union

The Lords' independent scrutiny function is cited in Westminster comparisons with the EU Council as an example of executive-constraining upper-chamber review, though the chambers operate under very different constitutional arrangements.

United Kingdom

The Lords' role in revising complex technical bills like the CS&R Bill gives expert peers (former intelligence chiefs, telecoms regulators, technology executives) direct influence over the final legislative text.
