The Cyber Security and Resilience Bill (CSRB), clause by clause.
The Cyber Security and Resilience (Network and Information Systems) Bill would amend the NIS Regulations 2018 to bring data centres, managed service providers, large load controllers and critical suppliers into scope, tighten incident reporting to 24 and 72 hours, and give ministers new regulation-making and national security powers. It has 70 clauses in five Parts. Each is explained below, with a link to the official text.

The five Parts
Part 1 defines "the NIS Regulations" as the Network and Information Systems Regulations 2018 and gives a map of the rest of the Bill: Part 2 amends those Regulations, Part 3 gives the Secretary of State new powers, and Part 4 covers national security directions.
Part 2 · Clauses 3 to 23The NIS RegulationsPart 2 would amend the NIS Regulations 2018. It brings data centres, large load controllers and managed service providers into scope, lets regulators designate critical suppliers, replaces incident reporting with a 24-hour initial and 72-hour full notification, adds customer notification, and rewrites cost recovery, information powers and penalties.
Part 3 · Clauses 24 to 43Secretary of State powersPart 3 would let the Secretary of State specify essential activities and regulators, set strategic priorities, make regulations imposing security duties (penalties capped at the greater of £17m and 10% of turnover) and issue a code of practice, with a report on the legislation at least every three years. Most of it depends on future regulations.
Part 4 · Clauses 44 to 67National security directionsPart 4 would let the Secretary of State give binding national security directions: vendor-related directions about a supplier's goods or services, and general directions where a compromise threatens national security. Breaches could cost up to £17m (the greater of £17m and 10% of turnover once regulations exist) plus daily penalties. It adds a regime review and foreign powers register.
Part 5 · Clauses 68 to 70Extent, commencement and short titlePart 5 says the Bill would extend to the whole UK, sets out when each provision would come into force (some on Royal Assent, some two months later, the rest on dates set by regulations), and gives the short title: the Cyber Security and Resilience (Network and Information Systems) Act 2026.
Schedules 1 and 2Enforcement; minor amendmentsSchedule 1 extends inspections, enforcement notices and appeals. Schedule 2 makes minor and consequential amendments. Both are explained on the Part 2 page.
Part 1 · Clauses 1 and 2Introduction
Part 1 defines "the NIS Regulations" as the Network and Information Systems Regulations 2018 and gives a map of the rest of the Bill: Part 2 amends those Regulations, Part 3 gives the Secretary of State new powers, and Part 4 covers national security directions.
Clause 1Meaning of “the NIS Regulations”
What the Bill saysThroughout the Bill, "the NIS Regulations" means the Network and Information Systems Regulations 2018 (S.I. 2018/506).
Most of the duties people associate with the Bill are not free-standing: they are amendments to the 2018 Regulations. That is why many provisions are cited as a regulation number (for example regulation 14E) as well as a clause number.
Clause 2Overview of Act
What the Bill saysClause 2(1) and (2): Part 2 amends the NIS Regulations, including amendments that would:
- extend the Regulations to data centres, load control services and managed services;
- provide for the designation of critical suppliers;
- change the reporting of incidents;
- cover cost recovery, sharing and gathering of information, and enforcement.
Clause 2(3) and (4): Part 3 gives the Secretary of State powers to specify regulated activities and designate regulators (Chapter 1), designate a statement of strategic priorities (Chapter 2), make regulations on the security and resilience of network and information systems (Chapter 3) and issue a code of practice (Chapter 4). Chapter 5 requires a report on the legislation.
Clause 2(5): Part 4 gives the Secretary of State powers to give directions where there is a risk to national security.
Clause 2 is a signpost with no legal effect of its own. It is useful as a quick map: Part 2 changes the rules that apply on day one of commencement, while Part 3 is mostly enabling powers whose detail will come later in regulations.
History. A Government amendment agreed at Lords Third Reading on 2 November 2026 (HL Bill 62–I, amendment 1; not in the HL Bill 62 print) changes "persons providing data centres" in clause 2(2)(a) to "persons providing data centre services". It is a drafting change.

Changes agreed at Lords Third Reading
HL Bill 62 is the last full reprint. The Lords agreed four Government drafting amendments at Third Reading on 2 November 2026 (HL Bill 62–I). None changes a clause number or the substance of a duty:
- Clause 2: "persons providing data centres" becomes "persons providing data centre services".
- Clause 24: the pointer to the meaning of "regulated person" now reads "section 30(2) and (5)" (Bill wording), pointing to clause 30(5) as well.
- Clause 36: the definition of "regulated person" now adds "(and see also section 30(5))".
- Clause 42: after "section 30(2)" now adds "(and see also section 30(5))".
How to read this explorer
Each clause has two parts. What the Bill says is a close paraphrase of the clause text, with subsection references so you can check it. What this means in practice is our interpretation, and is labelled as such. Where the text leaves something to future regulations, or does not answer a question, we say so rather than guess.
Many clauses work by inserting new regulations into the NIS Regulations 2018, so a provision often has two references: the Bill clause (for example clause 15) and the regulation it would create (for example regulation 14E). Regulation numbers did not change when the Lords renumbered the clauses.

Questions
HL Bill 62, the print as amended on Report in the House of Lords (26 October 2026), has 70 clauses in five Parts and two Schedules. The version brought from the Commons (HL Bill 32) had 61; the Lords added clauses on AI agents, vendor-related directions, a review of the regime and a register of foreign powers.
Clause 15. It would replace regulation 11 of the NIS Regulations and add regulations 11A, 12A and 14E, requiring an initial notification within 24 hours and a full notification within 72 hours of first becoming aware of a notifiable incident, copied to the CSIRT. Clause 16 adds customer notification for data centres, digital and managed service providers.
Clause 21 sets the NIS Regulations caps: the greater of £10m and 2% of worldwide turnover (standard maximum) or the greater of £17m and 4% (higher maximum). Clause 33 caps penalties in future Part 3 regulations at the greater of £17m and 10%. Clause 54 sets Part 4 penalties for breaching a direction: up to £17m (the greater of £17m and 10% of turnover once regulations under clause 54(5) are made), plus up to £100,000 a day.
Clause 69 sets commencement. Part 1, Chapters 1, 3 and 6 of Part 3, clause 41 and Part 5 would start on Royal Assent; clause 18(3) and (4), Chapter 2 of Part 3 and Schedule 2 paragraphs 3, 4 and 15 two months later; everything else, including the main Part 2 duties, on days set by regulations. No dates have been set. One caveat: clauses 66 (review of the NIS regime) and 67 (register of foreign powers) sit in Part 4, so on the HL Bill 62 text they commence only by regulations, even though their own deadlines run from Royal Assent.
No. As of 9 November 2026 the Lords have completed their stages and the Commons has still to consider the Lords amendments. The duties described on this site are proposals until Royal Assent and commencement.
A Bill is drafted as the Act it will become, so its text refers to "sections". While it is a Bill, Parliament calls them clauses. This explorer uses "clause"; the numbers are the same.
