Enforcing IR(ME)R

  • Organisations we regulate

CQC is the enforcing authority for England under IR(ME)R 2017. We enforce IR(ME)R using our powers under the Health and Safety at Work Act etc. 1974.

Our specialist IR(ME)R inspectors monitor and inspect premises that use ionising radiation. If a provider (employer) is not complying with IR(ME)R, we will recommend improvements. These must be made within a certain timescale.

In serious cases we can use our powers to take enforcement action to keep people safe.

Enforcement action register

When we take enforcement action against a provider, we publish a summary.
