CNC publishes 2026/27 plan for armed security at UK sites

Published on 7 April 2026, the Civil Nuclear Constabulary has set out its Annual Business Plan for 2026/27. It prioritises keeping civil nuclear sites secure, protecting nuclear material, and providing armed policing at other parts of the UK’s critical infrastructure when asked. We’ve read it so you don’t have to, and we’ll keep the jargon light. (gov.uk)

Quick explainer: the Civil Nuclear Constabulary (CNC) is the UK’s specialist armed police force for civil nuclear sites in England and Scotland. It also protects nuclear materials in transit and, increasingly, some non‑nuclear critical infrastructure. The force is governed by the Civil Nuclear Police Authority and employs over 1,800 officers and staff. (gov.uk)

Where this plan sits: the 2026/27 Business Plan lines up with the Civil Nuclear Police Authority’s 2024–2027 Strategic Plan, now in its final year. CNC leaders say this work lands during national police reform and a shifting global threat picture, and they restate an ambition to be seen as the UK lead for armed protective security across critical national infrastructure. (gov.uk)

In plain English, “armed protective security” means a visible, trained, armed police presence on site to deter, detect and, if required, stop an attack. CNC Authorised Firearms Officers work around the clock and also escort sensitive nuclear material when it moves; training follows College of Policing standards. (assets.publishing.service.gov.uk)

Beyond nuclear: the CNC’s expanded remit now supports non‑nuclear critical sites. The plan notes four non‑nuclear facilities at full operating capability. Public documents list examples such as the gas terminals at Easington, Bacton, St Fergus and Garlogie, and duties also extend to British‑flagged cross‑Channel ferries. The Energy Act 2023 allows ministers to authorise these additional tasks; the government confirmed such activity in 2024. (gov.uk)

Why now: ministers have signalled a bigger role for nuclear energy, with fresh investment and innovation. Parliament’s Energy Security Committee has been reviewing the route to as much as 24GW of nuclear capacity by 2050. More reactors or life extensions mean more sites, more movements and, therefore, more security work. (gov.uk)

How this keeps people safe: the CNC model focuses on prevention. High‑visibility armed patrols are designed to deter hostile reconnaissance; close working with local Home Office forces and Police Scotland supports rapid response; and armed escorts reduce risk during transport. This is the quiet, routine work that prevents headlines. (gov.uk)

If you live near a protected site, you may notice visible patrols, occasional vehicle stops and community engagement. That visibility is deliberate: the plan sets out a highly visible, armed posture to deter and respond quickly. You might also see targeted activity under Project Servator, which uses unpredictable deployments to disrupt hostile planning. (assets.publishing.service.gov.uk)

Accountability matters. The plan promises an efficiency programme to deliver best value while keeping the CNC’s core mission front and centre. Oversight sits with the Civil Nuclear Police Authority, and inspections are carried out by His Majesty’s Inspectorate of Constabulary and Fire & Rescue Services under statute. Those are your touchpoints for checking performance and culture. (gov.uk)

People and culture are part of security. CNC says it relaunched its Proud to Protect cultural principles in March 2026 and ties them to the policing Code of Ethics. The plan underlines inclusion, integrity and high standards of behaviour for every officer and member of staff. (assets.publishing.service.gov.uk)

For policy students: the plan nods to the Police Reform White Paper, which explores centralising some national functions. The CNC isn’t within the scope of the initial review, but its leadership is engaging with the Home Office and other non‑Home Office forces. It’s a timely reminder that specialist policing feels the ripple effects of Whitehall decisions. (assets.publishing.service.gov.uk)

How to read this well: look for the activity for 2026/27, the corporate risks and the governance framework-these show how success will be judged and who checks it. The full plan is on GOV.UK, and the summary news post is a good starting point for verifying future claims you see online. (assets.publishing.service.gov.uk)
