Cyber Security and Resilience (Network and Information Systems) Bill (Fourth sitting)

Kanishka Narayan Excerpts

Thursday 5th February 2026 Public Bill Committees

[The Chair]

With this it will be convenient to discuss the following:

Amendment 10, in clause 10, page 9, line 29, at end insert—

“(2A) The measures taken by an RMSP under paragraph (1) must ensure that the number of customers to whom the RMSP provides services does not exceed the critical risk threshold.

(2B) In paragraph (2A), the ‘critical risk threshold’ is the number of customers within a sector or subsector where an incident affecting the provision of services to those customers by the RMSP would result in disruption that is likely to have a significant impact on the economy or the day-to-day functioning of society in the whole or any part of the United Kingdom.

(2C) Paragraph (2D) applies where the number of customers to whom an RMSP provides services exceeds the critical risk threshold by virtue of contracts entered into before the coming into force of section 10 of the Cyber Security and Resilience (Network and Information Systems) Act 2026.

(2D) The RMSP must take steps to reduce the number of customers to below the critical risk threshold, including exercising any right to terminate a contract or vary the terms of a contract.”

This amendment would place a duty on relevant managed service providers (“RMSPs”) to ensure that they do not provide services to manage the technology systems for a number of customers that exceeds a critical risk threshold, such that an incident affecting those services would be likely to result in significant disruption in the United Kingdom. This would prevent an RMSP managing the technology systems for a whole sector or subsector. Provision is also made for a situation where an RMSP is in breach of the critical risk threshold because of contracts entered into before the enactment of the Bill.

Clauses 10 and 11 stand part.

[The Parliamentary Under-Secretary of State for Science, Innovation and Technology (Kanishka Narayan)]

I welcome you, Ms McVey, to the most exciting event in Parliament this week.

[The Chair]

I question that, but carry on.

--- Later in debate ---

[Kanishka Narayan]

What a pleasure it is to serve with you in the Chair. Clause 9 brings large and medium-sized managed service providers—MSPs—into the scope of the Network and Information Systems Regulations 2018. MSPs are organisations that provide an ongoing IT function, such as an IT help desk or cyber-security support, to an outside client. In doing so, MSPs often have widespread and trusted access to clients’ networks and systems. A single targeted attack can ripple outward, disrupting thousands of other systems. That makes MSPs attractive targets for cyber-attacks. Last year an attack on Collins Aerospace halted check-in and boarding systems at major European airports, causing international disruption. Such attacks highlight what can happen if a single point of failure is compromised, and the importance of managed service providers implementing robust cyber-protections. Despite that, MSPs are not currently regulated for their cyber-security in the UK. As organisations rely more and more on outsourced technology, we must close that gap. The clause provides essential definitions of a “managed service” and of a “relevant managed service provider” to clearly set out which organisations are in scope of the regulations.

Clause 10 imposes new duties on MSPs that have been brought into scope by clause 9. For the first time, such businesses must identify and manage risks posed to the network and information systems that they rely on to provide their managed services. As part of that duty, MSPs must have

“regard to the start of the art”,

meaning that they must consider new tools, technologies, techniques and methods that threat actors may employ. That includes artificial intelligence, and means that providers must deploy the right tools to mitigate the risks and take action to minimise the impact of incidents if they occur. By bringing MSPs into scope of the regulations and imposing such security duties on them, we will strengthen cyber-security and resilience across supply chains, reduce vulnerabilities in outsourced IT services and better protect businesses and services across the UK.

[Alison Griffiths (Bognor Regis and Littlehampton) (Con)]

Bringing MSPs into scope is the right direction of travel, and MSPs sit at points of concentrated risk, but they are not all the same and the real risk is not size alone but the level of privileged access and cross-customer dependency. Proportionality will be critical under these provisions if we want better security, not just box-ticking.

[Kanishka Narayan]

I agree very much with the hon. Member’s point, and a similar sentiment is expressed elsewhere in the Bill, in that it ensures that the focus is primarily on large and medium-sized MSPs, and that small businesses and microbusinesses are dealt with in a deeply proportionate way. That is an important point to take into account.

Clause 11 defines what it means for a digital or managed service provider to be

“subject to public authority oversight”

under the NIS regulations. Public authority oversight is defined as “management or control” by “UK public authorities” or by a board where the majority of members are appointed by those authorities. Such MSPs are already subject to requirements in the Government cyber-security strategy, which is mandatory for Government organisations. That ensures that cyber-resilience standards remain strong for services linked to public functions, while preventing disproportionate burdens on providers already subject to public authority governance.

In response to points raised by hon. Members in prior Committee sittings, I flag the engagement that we have conducted in coming to the definition of MSPs in question. In particular, beyond the provisions of the 2022 consultation, prior to the introduction of the Bill, we conducted a range of bilateral meetings. We have had multiple conversations with the industry body techUK, roundtables with digital firms, and we engaged through the National Cyber Security Centre-led MSP information exchange with 40 providers in this context, and undertook market research mapping the MSP market. As a consequence, adjustments to the definitions at the heart of this provision have been agreed with incredibly deep and broad engagement across the industry to arrive at a widely-welcomed definition.

[Lincoln Jopp (Spelthorne) (Con)]

It is a pleasure to serve with you in the Chair, Ms McVey. Small and medium-sized enterprises are defined by the headcount of full-time employees, yet in the world of IT, particularly for managed service providers, data centres and digital service providers, that is not a helpful metric to understand size and scale. Did the Department consider reevaluating the size of digital and managed service providers based on the through-flow of transactions or data rather than headcount? When I worked in the world of tech, there was a ratio for headcount that was totally different from other sorts of businesses.

[Kanishka Narayan]

The hon. Member raises an important point about the operating leverage of technology businesses. The Bill directly focuses on size as one proxy for risk, but it is not a complete or perfect proxy. That is why, through the critical supplier provisions, it ensures that any smaller providers can be caught in scope as essential services.

[Dr Ben Spencer (Runnymede and Weybridge) (Con)]

It is a pleasure to serve under your chairmanship, Ms McVey.

Clause 9 brings within scope of the NIS regulations a new category of technology service providers, known as relevant managed service providers. MSPs play a critical role in the UK economy. Research conducted by the Department for Science, Innovation and Technology under the last Government suggests that 11,000 MSPs were active in the UK in 2023, of which 1,500 to 1,700 were medium or large organisations that would be in scope of the Bill. Micro and small enterprises that offer managed services are excluded from the scope of regulation but have the potential to be designated as critical suppliers under other provisions, which we will come to shortly.

MSPs are critical to the functioning of the multiple businesses that they serve, offering contracted IT services such as helpdesk and technical support, server and network maintenance, and data back-up. In many cases, they also provide managed cyber-security solutions to their customer bases. Consequently, these businesses often have significant access to their clients’ IT networks, infrastructure and data, which makes them attractive and valuable targets.

[Kanishka Narayan]

Once again, the shadow Minister is auditioning for roles in the Treasury, by talking about general taxation, and in the Department for Business and Trade, by talking about general philosophies of regulatory reform. I will focus on matters within the scope of our debate, and on four aspects in particular.

First, Opposition Members have raised questions about definition. They have been answered frequently, but I am happy to repeat the answer. The scope of MSP coverage, which focuses on large and medium-sized MSPs, means that something in the order of 11% of MSPs are covered, by number, but 97.6% of the UK’s MSP revenue is covered. I hope that that gives sufficient assurance as to the coverage of the Bill. Of course, the critical supplier provisions cover any others.

--- Later in debate ---

[Lincoln Jopp]

Will the Minister give way?

[Kanishka Narayan]

I am happy to proceed and to focus on Crown ownership of data centre provision to others. For those reasons, I continue to commend clauses 9 to 11 to the Committee.

[Lincoln Jopp]

Will the Minister please clarify whether he thinks that, as page 102 of the impact assessment states, the hourly rate for a lawyer changing a contract is £34?

[Kanishka Narayan]

I simply point out to the hon. Member that the pricing for law varies materially. I hope that, with the benefit of technology, it continues to be very accessible to all relevant providers.

[Lincoln Jopp]

I am sorry, but that is nonsense. The footnote on the page that cites £34 an hour for a contract lawyer directs us back to the Office for National Statistics. I hope that the Minister lives in the real world—he has clearly worked in the business world—so he knows that that is nonsense. Does he agree that that pretty well undermines that section of the impact assessment?

[Kanishka Narayan]

Having closed the debate, I am happy to conclude.

Question put and agreed to.

Clause 9 accordingly ordered to stand part of the Bill.

--- Later in debate ---

[The Chair]

The point has been made clearly on the record. We can take it beyond this room, and perhaps you can write to the Minister afterwards for clarification.

Clauses 10 and 11 ordered to stand part of the Bill.

Clause 12

Critical suppliers

Question put, That the clause stand part of the Bill.

[Kanishka Narayan]

Clause 12 will introduce a new power for regulators to designate critical suppliers to organisations as in scope of the NIS regulations. These are suppliers that are so pivotal to the provision of essential digital or managed services that a compromise or outage in their systems can cause a disruption that would have serious cascading impacts for our society and economy; I am thinking in particular of the Synnovis incident in 2024, when 11,000 medical appointments were cancelled across London hospitals as a result of an attack on a pathology service provider.

The clause will ensure that the power to designate can be exercised only where suppliers pose a credible risk of systemic disruption and when the regulator has considered whether the risks to the supplier cannot be managed via other means. In other words, it is a very high bar indeed. 

The clause provides safeguards for suppliers, which must be consulted and notified during the designation process. It also requires regulators to consult other relevant NIS regulators when they are considering whether to designate, or decide to do so, ensuring that they have an accurate understanding of how suppliers are already regulated. 

Finally, the clause provides for designations to be revoked when risks no longer apply or when a supplier has met the thresholds for regulation as a relevant digital service provider or relevant managed service provider. It should be noted that the clause does not set out the security duties on critical suppliers; these will be defined in secondary legislation following an appropriate period of consultation.

By addressing supply chain vulnerabilities, this measure will strengthen the resilience of the UK’s essential and digital services on which the public rely every day. I commend the clause to the Committee.

[Alison Griffiths]

The clause merits close scrutiny, because it is the point in the Bill where risk is supposed to be addressed beyond the individual operator and into the supply chain. In plain terms, clause 12 will allow the regulator to designate a supplier as critical where disruption to that supplier would have a significant impact on the delivery of an essential or digital service. The trigger is impact, not size or sector. That approach is sensible, but I want to stress-test how it works in the context of operational technology.

Across power, telecoms, transport, water and industry, many essential services rely on the same family of industrial control equipment. Substations, signalling systems and industrial plants may look different, but they often run on identical controlled devices and firmware supplied by a very small number of manufacturers.

The risk is not hypothetical. A single vulnerability in widely deployed OT equipment can create a common mode failure across multiple sectors at the same time, even where each operator is individually compliant with its duties. At the moment, the Bill places obligations squarely on operators of essential services, but in OT environments, operators do not control the design of equipment, the firmware, the vulnerability disclosure process or the remote access arrangements that vendors often require as a condition of support.

As Rik Ferguson highlighted in written evidence to this Committee, uncertainty about how and when suppliers might be brought into scope can lead to defensive behaviour and late engagement. The risk is amplified in OT, where suppliers may discover vulnerabilities before operators do, and where one operator may report an issue, while others in different sectors, using identical equipment, remain unaware.

There is also a traceability problem. OT equipment is frequently sold through integrators and distributors. Manufacturers may not have a clear picture of where the equipment is ultimately deployed. Without that visibility, national-scale vulnerability notification and co-ordinated response become very difficult.

UK Finance has also drawn attention to the complexity of multi-tier supply chains and the need for clear accountability when regulatory reach extends upstream. The clause recognises that reality, but its effectiveness will depend on how consistently and predictably designation decisions are made across sectors.

My concern is not about the existence of the power. It is about whether, in practice, the power will be used early enough and clearly enough to address shared OT risks before they become cross-sector incidents. Operational resilience today depends less on individual sites and more on the security practices of a relatively small— I would say very small—number of OT suppliers that sit behind them. The clause has the potential to address that, but only if its application is focused on genuine systemic risk and supported by clear signals to suppliers and operators alike. For those reasons, the clause warrants careful consideration as the Bill progresses.

--- Later in debate ---

[Dr Spencer]

I really appreciate my hon. Friend’s intervention. It goes incisively to the heart of the concern about how these provisions are currently drafted. I really struggle to see how an OES that is providing a service to another OES could effectively argue that it is not within the full scope of these regulations. We have a lot of OESs in this country. It may be the Minister’s and the Government’s intention to essentially have a proxy regulatory framework for suppliers to OESs going forward—it is being kept very loose, because there is some flexibility in that, but that in itself will be a problem.

I worry that a lot of providers are going to think to themselves, “Why should we provide to an OES when we might be at risk of being designated as a national critical supplier?” Surely that is a concern that will have a chilling effect on organisations supplying to OESs, because of the risk of being found within the scope of this additional regulatory burden.

Don’t get me wrong; as I have said, companies should be taking cyber-security seriously, as should everyone. However, not everyone should be subject to the various regulations and data-sharing requirements that this Bill provides for. I suspect that many organisations will be very concerned. If there is a risk of designation as a critical supplier, companies will already be instructing lawyers and other organisations to manage that corporate risk.

If an organisation starts supplying to a hospital trust, or to whoever it may be, it might think, “Actually, we’re likely at risk of being designated, so we need to start doing some work and investment, either to challenge that designation or begin doing the preparatory work.” Maybe that is the intention: to effectively regulate the entire sector providing to OESs without actually lifting a finger in terms of regulation through this Bill. If that is the case, I am sort of sad, because I think it is better to be clear-cut about it. I would be grateful if the Minister answered that point directly.

Finally, in terms of OESs, we have already mentioned the fact that Government and local authority IT infrastructure and services are among the biggest risks in our system. I was really struck by the evidence from the NHS on Tuesday, in which our witnesses described data-sharing operations with adult social care, which is of course provided by local authorities.

It seems quite perverse, if I may say so, that a GP surgery, which is a private organisation, could be deemed a critical supplier to a hospital in terms of patient information sharing. Quite frankly, I would like the Minister to answer the question specifically: does he envisage primary care GPs being in scope because of data sharing of hospital records with NHS trusts? GPs could fall within scope as critical suppliers, while social care records, which are provided by local authorities, would not. There are all these weird situations that could emerge because of the scope and the looseness of these provisions, with all the consequent harms and problems. I look forward to hearing the Minister’s responses to my points.

[Kanishka Narayan]

First, I will respond to the apt and thoughtful points from the hon. Member for Bognor Regis and Littlehampton on operational technology. I can confirm to her that both vendors and providers of operational technologies will be covered by the provision of the five-step test for critical supplier designation. That is an important aspect when thinking about supply chains and the presence of operational technology where it is of critical interest.

The hon. Member for Spelthorne raised a very accurate point about proportionality in the provisions of the Bill, and in particular the impact assessments, statements, or limited statements on critical supplier impacts. As he will know very well, the Bill takes a very nuanced position on proportionality. When a sector is designated, there will be total clarity on the number of suppliers affected and on the ultimate impact. We will have sight of that.

The provision on critical suppliers was asked for by industry. The reason why the Bill does not specify critical suppliers is that it is simply not for the Government to specify how a business can or cannot continue. It is for businesses and regulators to work that through by understanding the depth of expertise that businesses have. We have started to do that, but that is precisely why the critical suppliers provisions have been delegated to secondary legislation and subsequent guidance.

[Lincoln Jopp]

Will the Minister give way?

[Kanishka Narayan]

I commit to giving way to the hon. Gentleman at the end of my speech. He asked about schools. I am happy to confirm that schools are not in the scope of the Bill.

In response to the shadow Minister, I highlight that the five-step test is cumulative: a business must meet all the conditions to be designated as critical, not just one. I think that answers the series of logical puzzles that he tied himself up in.

I am very happy to confirm to the Committee that it is expected that regulators will use information gathered from their oversight of operators of essential services, relevant managed service providers and relevant digital service providers to identify potential critical suppliers for designation. They can also ask organisations for more information to support their assessments. Future supply chain duties will also require organisations to share supply chain risk assessments with regulators. A supplier can be designated only after the regulator has completed an investigation process, including serving notices and holding a consultation, and confirmed that the criteria are met. Designated suppliers will also have the right to challenge decisions through an independent appeals process.

[Dr Spencer]

Will the Minister give way?

[Kanishka Narayan]

I commit to giving way at the end of my speech to the shadow Minister and the hon. Member for Spelthorne.

On the question of consultation, I am happy to confirm that the team in question has set up an implementation-focused effort. We have started to engage with regulators already, and there will be an extensive process of engagement on the Bill with business, as has been conducted historically.

The shadow Minister highlighted a number of logical puzzles. I have worked in a range of businesses and public sector organisations, and most have business continuity services. His hypothetical idea that businesses do not understand alternative provision, and whether they are or are not in a position of exposure, is well solved in the real world. I would give more credit to our expert witnesses from NHS Scotland than he did in recognising that they said that they frequently deal with the question of critical suppliers in co-ordination with competent authorities.

[Lincoln Jopp]

The Minister came back with an answer on proportionality, saying that it is not for Government to decide what is essential. He missed out the next bit, which is, “We’re just going to regulate critical suppliers and pass laws about them, but we don’t know how many there are, and we don’t know how much the policy is going to cost.” Would he accept that characterisation as the logical conclusion of what he said?

The Minister also said that schools were not covered by the Bill. As far as I am aware, patient data and children’s data are two of the most precious things that we have, so I would like to know why schools are not covered by the Bill.

[Kanishka Narayan]

On the first point, I am afraid that I do not think that was an appropriate characterisation, because where the sectoral scope is clear and where there is a clear risk of critical national infrastructure and essential services being directly exposed, we have specified that in the Bill. We have looked at the impacts set out in the impact assessment. For the critical suppliers in those sectors—I would expect them to be very limited in number—we have made sure that regulators and businesses have the flexibility to set the requirements directly, rather than them being set here in Parliament.

[Chris Vince]

I was going to intervene on the hon. and gallant Member for Spelthorne, but he is bigger than me. I recognise the points he made about the number of critical suppliers, but I come at the question from the other angle: doing nothing may leave critical suppliers at risk. Although we might not know the exact number, as he correctly asserted, it is important that we do something and introduce the regulations as soon as we can to protect our critical infrastructure.

[Kanishka Narayan]

I thank my hon. Friend for that point. This issue has not come out of nowhere. Industry and a number of organisations asked that we introduce the measures in the clause.

Beyond the very clear five-step test for critical supplier designation, the Bill provides that the requirements on critical suppliers are proportionate. The reason why we have both the five-step test and the provisions in the Bill is that, in most cases, if the risk assessment suggests so, the security requirements set out in the Bill will be less onerous in most cases. They will be specified in secondary legislation and guidance.

On the question of schools, and more broadly the question of public sector authorities, I entirely accept that the handling of pupil data in schools is a critical aspect of our public service operations. The reason why public service authorities have largely been left out of the Bill’s scope is because we do not need to wait for the legislative process to act. We have been working, not least closely with the Government’s cyber-security strategy and the cyber action plan, to ensure that pupil data is kept securely and robustly.

[Dr Spencer]

The Minister is, of course, within his rights to snarkily dismiss the questions that I have raised, but I should point out that the stuff that is debated in Parliament, whether in Committee or on the Floor of the Chamber, is relevant when it comes to future legal disputes after a Bill is passed. The questions I have asked about the application of the Bill’s provisions will be important parts of the legal disputes that I expect will arise after its implementation. When people look back through the Minister’s dismissive comments, I hope they have other resources that they can go to for settling legal arguments. However, he may choose to respond fully now, or in writing if he cannot provide me with an answer.

[Kanishka Narayan]

I believe that where the shadow Minister laid out any specific concerns, I was able to set out answers, not least on the process for the designation of critical suppliers and the availability of an appeals process. Where his points were more in the realm of specific hypothetical puzzles, I have stayed clear for precisely the reasons that he highlights. This is serious stuff that can form the basis of how businesses and others plan, rather than specific judgments that we ought not to speculate about in this House.

Question put and agreed to.

Clause 12 accordingly ordered to stand part of the Bill.

Clause 13

Provision of information by operators of data centre services

Question proposed, That the clause stand part of the Bill.

[The Chair]

With this it will be convenient to discuss clause 14 stand part.

[Kanishka Narayan]

Clause 13 ensures that operators of data centres provide essential information to regulators, enabling them to properly monitor their sector and its cyber-resilience. The clause requires operators to submit key details, such as names, addresses and contact information, within three months of designation, and to update regulators within seven days if anything changes. Regulators are required to maintain a list of designated entities. By keeping regulatory records current, the clause strengthens our ability to monitor and protect essential services and respond to incidents that could affect businesses, public services and national security. The clause plays a key foundational role in the Bill’s wider framework for cyber-security and resilience.

Like clause 13, clause 14 places legal duties on digital and managed services providers to provide essential information to their regulator—in this case, the information commission. Like operators of data centre services, RDSPs and MSPs will be required to register with the information commission within three months, submitting key details, such as names and contact information, and to update regulators within seven days if anything changes. Organisations based outside the UK will be required to nominate a UK representative and provide contact details. To strengthen cross-agency support and recognise the key role that these businesses play in the UK economy and society, the information commission will be required to share its registers of relevant digital and managed service providers with GCHQ. Those proportionate steps will enable authorities to do their job and respond when it matters.

[Dr Spencer]

Clause 13 requires in-scope data centre operators to provide certain information to their designated competent authorities, which—subject to Government amendment 11, which we passed earlier—will now be solely Ofcom, and to keep that information up to date. The information includes the data centre operator’s address and the names of directors. It must be provided within three months of the data centre operator’s designation. For data centres that meet the threshold criteria, that would be three months after clause 4 comes into force. Other OESs are not subject to an equivalent requirement to provide information to their sector regulator. That reflects the fact that the Government currently have limited information about the data centre sector.

RDSPs are already required, under regulation 14 of the NIS regulations 2018, to provide their contact details to the information commission, as their sector regulator. Clause 14(2) amends regulation 14 to require RDSPs to provide more information, including about their directors and the digital services they provide. It would also require the information commission to share a copy of its register of RDSPs with GCHQ. Clause 14(9) requires RMSPs to register with the information commission and to submit the same contact details as RDSPs. RMSPs must nominate a UK representative if they are based outside the UK. The information commission will be required to maintain a register of RMSPs and to share it with GCHQ. Clauses 13 and 14 give Ofcom and the information commission access to more detailed information about regulated entities and facilitate regulatory oversight of the data centre RDSP and RMSP industries in the UK.

Question put and agreed to.

Clause 13 accordingly ordered to stand part of the Bill.

Clause 14 ordered to stand part of the Bill.

Clause 15

Reporting of Incidents by Regulated Persons

--- Later in debate ---

[The Chair]

Order. That is not relevant now.

[Kanishka Narayan]

I appreciate the intent behind the amendments and the shadow Minister’s position of understanding but not supporting them, which I share. I share his concerns about the potential for emerging risks posed by AI systems, not least in the realm of cyber-security. At the same time, I am conscious that we have not specified any risk factors in the Bill from a reporting point of view for the National Cyber Security Centre or the regulators. To do so in this context would place an undue priority on one category or source of risk.

For those reasons, although I understand the motivation behind the amendments and I am conscious of the risks posed by AI systems, I urge the hon. Member not to press them. The Bill is technology-agnostic rather than focused on particular areas of risk. The Government continue to work on mitigating AI risks, primarily at the point of use, but also through extensive Government capability, not least in the AI Security Institute.

[Dr Spencer]

I beg to ask leave to withdraw the amendment.

Amendment, by leave, withdrawn.

Ordered, That further consideration be now adjourned. —(Taiwo Owatemi.)
