Strategy 2020-25

Our strategy sets the direction we will take to 2025, recognising the global and nuclear landscape continues to evolve and change, and as a nuclear regulator, we must be agile in how we respond. Our mission is to protect society by securing safe nuclear operations, and our vision is to become a more modern ONR that delivers trusted outcomes that continue to inspire confidence. Together, these characterise our focus on exemplary regulation, with a clear intent to improve how we work, to give the best possible service and value.

Strategies and plans

Annual Report and Accounts

We are required by legislation to produce an Annual Report and Accounts.  Each year we set out how we have delivered our mission, and the progress we are making towards achieving our vision. The Report provides a summary overview of our regulatory, organisational and financial performance, as well as information on our governance.

Guide to nuclear regulation in the UK

This guide provides an explanation of the nuclear regulatory regime, explaining our activities and how we carry out our 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, we are subject to the government’s Business Impact Target (BIT) following the provisions of the Small Business, Enterprise and Employment Act 2015 which aims to:

  • reduce regulatory burdens on business and voluntary or community bodies;
  • ensure greater transparency around the impact of regulation on business; and,
  • provide greater incentives for regulators to design and deliver policies that better meet the needs of business.

We are 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 which includes:

  • BIT assessments for qualifying regulatory provisions (QRPs) along with the BIT score
  • a summary of non-qualifying regulatory provisions (NQRPs)

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

As set out in the Energy Act 2013, which established ONR, we are able to  recover the majority of our costs from dutyholders.

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

Stakeholder Survey 2021

Stakeholder feedback is essential to help us achieve our vision, so we understand what we do well and where we can do better. So we undertake regular, independent surveys to hear their views.

Our most recent survey was completed in January 2021 and received 262 responses. The majority of responses were received from licensees, industry/dutyholders, and government/agencies/public bodies.
