About us

The Civil Nuclear Constabulary (CNC) is the armed police force in charge of protecting civil nuclear sites and nuclear materials in England and Scotland.


We’re governed by the Civil Nuclear Police Authority.

Who we are

We employ over 1,600 police officers and members of staff at nuclear sites throughout the UK. We police each site in line with Nuclear Industry Security Regulations.

We also work with local police services, nuclear regulators and the Home Office.

Our responsibilities

We are responsible for the armed protection of civil nuclear facilities and materials whether they are on site or in transit. Counter-terrorism is a major part of our policing.

Our ambition

To be recognised nationally and internationally as the leading policing organisation for the armed protection of civil nuclear material and the critical national infrastructure of the UK.

Our mission

In partnership with the civil nuclear industry, national security agencies and regulatory bodies, the CNC will deter any attacker whose intent is the theft, sabotage or destruction of nuclear material, whether static or in transit, or the sabotage of high consequence facilities. If an attack occurs, CNC will defend that material and those facilities and deny access to them. If material is seized or high consequence facilities are compromised, the CNC will recover control of those facilities and regain custody of the material.

Our priorities

For 2023 to 2026, our three strategic goals are:

  • Maintain the CNC core mission and offer its unique capabilities to benefit the wider policing and security infrastructure

  • Enhance the effectiveness and efficiency of the CNC

  • Foster and maintain a unified and inclusive culture which supports an engaged and diverse workforce
