Welcome. Not all research conducted within the UK requires approval from an NHS Research Ethics Committee (REC). This decision tree will help you to determine if your study requires this type of approval.
At each stage of the decision tree you will be asked a series of questions. Read each question carefully and answer by clicking the YES or NO buttons.
This tool will not tell you whether you need any other regulatory approvals.
To help you with terminology, a GLOSSARY button is available on every page. All links to individual glossary items or other websites appear in purple text and open in a new window.
Post Market Surveillance is NOT usually considered research. However, there are some circumstances where an NHS REC approval may be required. See HRA guidance. Select YES below to determine if your post market surveillance requires NHS REC approval.
