London, November 12, 2025 — The United Kingdom is preparing to introduce stricter cybersecurity regulations aimed at strengthening the defenses of public services and critical infrastructure against cyberattacks, the government announced on Wednesday. The proposed laws would require companies providing essential services to both private and public sector organisations, including the National Health Service (NHS), to meet rigorous security standards.

Background: Rising Cyber Threats

The move comes after a series of high-profile cyber incidents in the UK. In 2024, hackers compromised the Ministry of Defence payroll system, while more recent attacks disrupted over 11,000 NHS medical appointments and procedures. Major brands including Marks & Spencer, the Co-op, and Jaguar Land Rover have also faced operational interruptions due to cyberattacks in the past year.

These events highlighted vulnerabilities in how companies with trusted access to sensitive networks operate, prompting the government to consider stricter regulatory oversight.

Key Provisions of the Proposed Laws

Under the proposed legislation, medium and large companies that provide services such as IT management, helpdesk support, or cybersecurity to both public and private sector clients would be subject to enhanced regulation.

The Department for Science, Innovation and Technology (DSIT) stated:

“Because they hold trusted access across government, critical national infrastructure, and business networks, they will need to meet clear security duties.”

Key requirements include:

• Mandatory reporting of significant or potentially significant cyber incidents to both the government and affected customers
• Robust contingency planning to manage the consequences of cyber incidents
• Designation of critical suppliers by regulators for essential services
• Tougher penalties for serious security breaches

Ransomware and Critical Infrastructure

The proposals also aim to curb ransomware payments. Public sector bodies and operators of critical national infrastructure — including the NHS, local councils, and schools — would be prohibited from paying ransom demands to cybercriminals.

The government emphasized that these measures are intended to reduce the risk of operational disruption and protect sensitive personal and national data, while discouraging cybercriminals from targeting public institutions.

Outlook

If approved, the laws will reshape cybersecurity responsibilities across the UK, holding suppliers more accountable for safeguarding both public and private sector networks. Analysts note that mandatory incident reporting and robust contingency plans could significantly improve transparency and preparedness in the face of increasingly sophisticated cyber threats.

The proposals reflect the UK’s recognition that cybersecurity is critical to national security, business continuity, and public trust in essential services.
