Strategies and plans

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.

ONR's Statement of intent for an environmental policy

We have committed in our Strategy 2020-25 to consider how we reduce our environmental and carbon impact in line with broader government objectives for net zero. Our Statement of Intent for ONR's environmental policy sets out our commitment to minimising and measuring the environmental impact of our operations, while we develop our environmental policy.

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.

Approach to regulating innovation

This document shows our we intend to deliver our commitment to embrace innovation, new approaches and technologies in how we regulate.

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)

The BIT is a deregulation target introduced by Government in 2015. It concerns the economic impact of regulation on business and we are required to produce a progress report each year.  

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.

Service standards

Our service standards aim to provide transparency in our approach to regulatory activities and set out what members of the public, licensees and dutyholders can expect from ONR. The purpose of the document is to act as a signpost to our Service Standards which describe our approach.

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

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.

Policy for openness and transparency

The policy sets out the guiding principles ONR will apply to the disclosure of information, in its communications and engagement with interested stakeholders and the wider public. It also demonstrates our ambition to provide greater opportunities for two-way engagement and ensures our communications are accessible to everybody as we embed our principles – accessibility, confidence and accountability.
