Make a complaint about ONR

Complaints originate from outside ONR, and are about ONR, in relation to a work activity for which ONR is responsible for regulating (nuclear safety, nuclear security, radioactive materials transport, safeguards or health and safety on a nuclear site), and where you think we may not have done our job properly.

If you are not satisfied with how ONR has handled your complaint

If you are not satisfied with how ONR has handled your complaint, you can contact your Member of Parliament (MP) and ask for your complaint to be referred to the Parliamentary and Health Service Ombudsman (PHSO). The PHSO can carry out independent investigations into complaints that injustice has been caused by maladministration on the part of UK government departments and some public bodies, including ONR.

You can find out who your MP is and write to them at:
