UK Ransomware Payment Ban: What UK CISOs Must Do Before the Law Changes

The UK government has confirmed it will introduce legislation to ban ransomware payments by public sector bodies and critical national infrastructure (CNI) operators, with a mandatory incident reporting regime applying economy-wide. For UK CISOs, the policy direction is settled — the implementation window is now.

Following a 12-week public consultation that closed in April 2025 and attracted over 270 responses, the government’s response confirmed the core proposals: a targeted payment ban covering public sector and CNI, a payment prevention regime requiring all other organisations to notify and pause before paying, and mandatory 72-hour ransomware incident reporting for all organisations. With the Cyber Security and Resilience Bill progressing through Parliament, CISOs across all sectors — not only public sector and CNI — need to act now to prepare their organisations for a fundamentally different ransomware response framework.

What Exactly Is the UK Proposing — and What Does It Mean in Practice?

The UK government’s ransomware legislative framework has three tiers. The first tier is a hard ban: public sector bodies (including central government, local government, NHS trusts, and schools) and CNI operators (in sectors including energy, water, transport, finance, and digital infrastructure) will be prohibited from paying ransomware demands. A ransom payment in breach of this ban would be unlawful.

The second tier covers all other UK organisations and individuals. Before making any ransomware payment, organisations must notify the National Cyber Security Centre (NCSC) and pause for a defined review period — currently expected to be 72 hours — during which the government can assess the threat, provide intelligence support, or in some circumstances direct against payment. This regime does not prohibit payment outside the hard-ban sectors, but it removes the option of quiet, undisclosed payment — which has been a common response to ransomware incidents in private sector organisations.

The third tier is mandatory incident reporting. All organisations — public and private, CNI and non-CNI — will be required to report ransomware incidents to the NCSC within 72 hours of discovery, with more detailed follow-on reporting as investigations develop. According to the government’s consultation response, 63% of respondents supported economy-wide mandatory reporting as a tool to improve national threat intelligence and improve law enforcement effectiveness against ransomware groups.

Executive Action:

• Determine your organisation’s tier classification: are you a public sector body, a CNI operator, or a private sector organisation subject to the payment prevention regime? The tier determines the legal obligation — and the severity of non-compliance risk.
• Review and update your ransomware incident response playbook immediately to remove any assumption that payment is a confidential, discretionary option — the legislative framework eliminates this under all three tiers.
• Brief the board and executive team on the payment ban proposals and their implications for cyber insurance coverage — many current cyber insurance policies cover ransomware payments, and insurers are already adjusting coverage terms in anticipation of the legislative changes.

How Should UK CISOs Rethink Ransomware Response Strategy in Light of the Payment Ban?

The payment ban fundamentally changes the CISO’s ransomware risk calculus. Where previously a ransomware payment — however undesirable — represented a plausible business continuity option, the legislative framework makes payment either unlawful or mandatory-notification for every UK organisation. CISOs must therefore rebuild their ransomware response strategy around a single assumption: payment is not available as a recovery mechanism.

This shifts the entire risk burden onto prevention, detection, and recovery capability. According to research by Semperis published in 2026, 60% of ransomware infections begin with compromised credentials — not sophisticated zero-day exploits. The identity infrastructure — Active Directory, Entra ID, and privileged access management — is both the most common entry point and the fastest path to enterprise-wide encryption. CISOs should treat identity security hardening as the single highest-priority ransomware prevention investment in 2026.

Recovery capability is equally critical. If payment is unavailable, organisations that cannot restore systems from clean backups within defined recovery time objectives face extended outages that are operationally and reputationally catastrophic. The FCA’s operational resilience framework (SS1/21) already requires financial services firms to demonstrate they can restore important business services within defined impact tolerances. The payment ban extends this logic to the practical question of ransomware recovery: if you cannot restore, you will remain hostage regardless of the legal position on payment.

Executive Action:

• Conduct a ransomware tabletop exercise before Q3 2026 using a scenario that explicitly excludes the payment option — this forces the organisation to test whether its actual recovery capability can meet its stated recovery time objectives.
• Commission an identity infrastructure security review covering Active Directory configuration, privileged access controls, Entra ID conditional access policies, and MFA coverage across all administrative accounts — prioritising the controls that stop the 60% of ransomware incidents that begin with credential compromise.
• Test backup integrity and recovery speed quarterly, not annually — the question is not whether backups exist, but whether they are clean, current, isolated from production, and restorable within your operational resilience tolerance windows.

What Are the Mandatory Reporting Obligations UK CISOs Must Prepare For?

Mandatory 72-hour ransomware incident reporting to the NCSC will require UK organisations to have pre-defined notification processes, clear internal escalation paths, and designated reporting contacts established before an incident occurs. The worst time to design a regulatory notification process is during an active ransomware attack — when system access may be restricted, key personnel may be unavailable, and decision-making is under extreme time pressure.

CISOs should note that the ransomware reporting obligation under the new legislation is separate from, and in addition to, existing notification obligations under UK GDPR (72-hour personal data breach notification to the ICO where a breach meets the risk threshold), NIS Regulations (for NIS operators), and DORA (for in-scope financial services firms from January 2025). An enterprise ransomware attack will typically trigger multiple concurrent reporting obligations, each with different content requirements, recipients, and timelines.

Critically, mandatory reporting creates a discoverable record of the incident, the organisation’s response, and any payment decision. For CNI and public sector organisations subject to the payment ban, the mandatory report is also the mechanism through which a prohibited payment would be identified. Legal and compliance functions should be engaged now to ensure the regulatory notification process includes appropriate legal privilege protections for internal communications during incident response. See our contact page to discuss bespoke incident response governance frameworks.

Executive Action:

• Build a multi-regulator notification matrix covering all concurrent reporting obligations for a ransomware scenario: NCSC (new ransomware regime), ICO (UK GDPR personal data breach), FCA/PRA (material operational incident), NIS authority, and DORA (if applicable) — with timelines, content requirements, and named notifiers for each.
• Engage General Counsel to establish legal privilege protocols for internal incident response communications from the outset of any ransomware incident — mandatory reporting requirements increase the volume of discoverable material and the importance of protecting privileged legal advice.
• Register your organisation’s NCSC reporting point of contact and test the notification process before the legislation comes into force — the NCSC My Cyber portal supports incident reporting, and the 72-hour clock will start from the moment of incident discovery, not the moment of containment.

How Does the Payment Ban Affect Cyber Insurance Coverage?

The ransomware payment ban has direct implications for cyber insurance programmes. Current policies in the UK market routinely include ransomware extortion coverage — reimbursing or directly funding ransom payments as part of the policy response. Once legislation prohibits payment for CNI and public sector organisations, this policy component becomes unenforceable for those entities. Insurers are already adapting coverage terms in anticipation of the legislative change.

For private sector organisations subject to the payment prevention regime — not the hard ban — insurance coverage of ransom payments may remain available, but only for payments made after complying with the notification and pause requirements. An undisclosed payment made in breach of the notification requirement would likely be uninsured and potentially expose the organisation to regulatory sanction. CISOs should review cyber policy terms with brokers immediately to understand how the legislative change interacts with existing coverage.

The shift away from payment-as-recovery also creates commercial pressure on insurers to price cyber coverage against the actual cost of recovery without payment — clean backup restoration, business interruption, forensic investigation, regulatory notification, and reputational management. CISOs whose organisations have invested demonstrably in identity security, backup integrity, and resilience testing will be better positioned in cyber insurance negotiations, as insurers increasingly adjust premiums and coverage terms based on measurable cyber resilience controls.

Executive Action:

• Request a formal review of cyber insurance policy terms from your broker in light of the UK ransomware legislative proposals — specifically, how will extortion coverage respond if payment is made after mandatory notification but within the permitted window for non-CNI organisations?
• Assess whether your current recovery capability — backup restoration timelines, business continuity plans, and crisis communications protocols — can sustain a 10-day recovery scenario without payment, and present the gap analysis to the board with a costed remediation plan.
• Document your cyber resilience investments — identity controls, backup testing, MFA coverage, tabletop exercise history — as a structured evidence pack for cyber insurance renewal negotiations, positioning your organisation’s risk profile accurately against the insurer’s post-payment-ban actuarial adjustments.
