Cyber attacks are not only more frequent but also more complex and more damaging. In the UK alone, over 40% of businesses were hit by an attack last year, and the National Cyber Security Centre (NCSC) recorded 429 cyber incidents, nearly half of which were nationally significant. The scale and reach of the threat to essential services, critical infrastructure and the wider economy have never been higher.
In response, the government has introduced the Cyber Security and Resilience Bill 2025. It represents the most significant reform of UK cyber regulation since the Network and Information Systems Regulations 2018 (NIS 2018). The goal is clear: to strengthen national resilience, protect critical services and close the gaps that cyber criminals and hostile states continue to exploit.
This is the UK’s biggest step forward in cyber regulation in over seven years. It is designed to strengthen national defences and protect the services businesses depend on every day.
Why The Bill Was Introduced
The original NIS 2018 regulations were an important first step. They helped raise standards for essential and digital services, but the cyber threat landscape has evolved dramatically.
Attackers now target shared services, cloud platforms, service providers and supply chains because one compromise can ripple through hundreds of organisations. Managed service providers (MSPs), data centres and supplier networks have become high-value entry points.
Two government reviews (2020 and 2022) found that while the NIS framework remained valuable, it needs updating to reflect how modern organisations operate and how attackers behave. A notable example of supply-chain risk occurred when a pathology services provider suffered a cyberattack, disrupting NHS trust services and highlighting the serious consequences of a supplier compromise.
The new Bill is designed to correct this. It expands the scope of regulation, strengthens oversight and improves incident reporting to reflect the realities of 2025.
What The Bill Changes
Expanded Scope
The NIS regime previously covered energy, transport, health, drinking water, digital infrastructure, and certain digital services. The new Bill extends this coverage to include:
- Medium and large data centres
- Medium and large managed service providers
- Large load controllers in smart energy systems
- Designated critical suppliers whose failure could disrupt essential services
These additions reflect the interconnected nature of modern business. If a managed service provider or data centre is compromised, the impact can spread quickly across thousands of clients. The Bill ensures these organisations adopt stronger controls and meet clear resilience standards.
Stronger and More Effective Regulation
Under the current system, twelve different regulators oversee the NIS regime. Their approaches have sometimes varied, creating inconsistent expectations across sectors.
The new Bill addresses this by introducing:
- More consistent and timely cyber incident reporting
- Clearer government priorities for regulators
- Greater powers for information sharing and enforcement
- Improved transparency and accountability for regulated bodies
The intention is simple: unified expectations, faster detection of issues and a stronger response when weaknesses appear.
Improved Incident Reporting
The Bill broadens the types of incidents that must be reported. Under NIS 2018, only disruptions to services required reporting. The new rules also include incidents that do not cause immediate disruption but still pose real risk, such as near misses, compromised accounts or suspicious activity that could develop into a wider breach.
This closes an important gap. Silent failures in the supply chain can escalate quickly. Regulators will now have visibility earlier, enabling faster action.
Tougher Enforcement and Penalties
The Bill raises the stakes for compliance. Non-compliant organisations could face substantial financial penalties linked to turnover, as well as closer scrutiny of their leadership accountability.
Cyber resilience is no longer just an IT issue. It is a board-level responsibility.
What This Means for UK Businesses
Managed Service Providers, Data Centres and Suppliers
For MSPs and data centres, the changes are significant. These businesses will now fall within the NIS regime and must:
- Demonstrate appropriate and proportionate security controls
- Maintain resilience planning and incident response procedures
- Report material incidents promptly
- Provide evidence of supply chain oversight
Customers will benefit from greater assurance and transparency.
Essential Services
Energy, water, healthcare, transport and digital infrastructure providers will face tighter expectations and more consistent regulation. These organisations should expect increased scrutiny of operational resilience, incident response and supplier management.
All Other Organisations
Even if your organisation is not directly regulated, the Bill will still affect you. Your suppliers and service providers will adopt stricter controls, and procurement processes will place greater emphasis on cyber resilience. Regulators will expect clearer evidence of due diligence and supplier assurance.
In short, the Bill raises the baseline expectation for everyone.
The Changing Role of IT Management
The Bill shifts cyber security from a technical project to a core part of operational resilience. IT teams will need to:
- Prove their ability to prevent, detect and recover from incidents
- Strengthen identity and access management controls
- Improve monitoring, logging and reporting
- Manage supply chain risk more proactively
- Provide clearer governance information to boards and regulators
The line between IT operations and business resilience will continue to blur.
