ONR publishes its Strategic Plan 2016-2020

The plan places attention on what our stakeholders expect from us and we intend to meet those needs. Throughout the plan, we have emphasised the importance of ONR taking an enabling approach to regulation: working together with stakeholders to influence improvements in nuclear safety and security.

The plan sets out the factors that will influence our work and the assumptions we have made about regulating the nuclear sector in the next few years, as well as how we deliver the commitments we have made to the public, ministers and government, licensees, dutyholders and our staff. Information on corporate risk, resources and finance planning is also contained in the plan.

Strategies and plans

Annual Report and Accounts

ONR is required by legislation to produce an Annual Report and Accounts which summarises our performance alongside other key developments across the organisation. The arrangements for and management of nuclear safety and security across UK nuclear sites, transport of radioactive materials and safeguarding nuclear material, are rightly measured against the highest standards.

Events reported to nuclear safety regulator

These report provides a list of events reported to the nuclear safety regulator including health and safety, but not including security events.


2001 to 2015

Guide to nuclear regulation in the UK

This guide provides an explanation of the nuclear regulatory regime by describing ONR's activities and how ONR carries out its work.

A guide to enabling regulation in practice

Enabling regulation is a constructive approach with dutyholders and other relevant stakeholders to enable effective delivery against clear and prioritised safety and security outcomes. This guide is designed to illustrate working examples of enabling regulation in practice.

Scheme of delegation

The scheme of delegation sets out who has the authority to make decisions within ONR.

Business Impact Target (BIT)

As a statutory regulator ONR is subject to the Government’s Business Impact Target (BIT) following the provisions of the Small Business, Enterprise and Employment Act 2015 which aims to:

ONR is required to publish an assessment of the economic impact on business of changes to regulatory policies and practices which are in scope of the BIT and is required to publish:

2017-2019 Parliament

2015-2017 Parliament

The 2015 to 2017 Parliament ran from 8 May 2015 - 8 June 2017

Government annual progress reports on the BIT are available on

Compliance with the Regulators' Code

The Regulators' Code came into force in April 2014 and aims to provide a framework for how regulators should engage with those they regulate.

How we charge for nuclear regulation

Established by the Energy Act 2013, the Office for Nuclear Regulation (ONR) is empowered by diverse legislation to recover the cost of its services from dutyholders.

As we strive to inspire a climate of respect, trust and confidence among our stakeholders, this booklet clearly explains how this charging system works.

Stakeholder survey 2018

In October 2018, we commissioned YouGov to complete a ‘dip test’ survey.  Smaller in size than the 2017 survey, the ‘dip test’ was designed to assess stakeholder views of our performance in some key areas. Representatives from across the sector were invited to take part and 329 responses to the online survey were received.

During 2019/20 we will continue to build upon the positive outcomes of the survey and will work to address areas of concern.  Our next full stakeholder survey will take place later this year.

Stakeholder survey 2017

In October 2017, we commissioned YouGov to complete our first stakeholder survey since vesting as a public corporation in 2014, and were delighted that 351 people took the time to respond, with 27 also taking part in in-depth interviews.
