Ethical Review Decision Making Tool

Any project that involves human participants, their data or tissue requires ethical review.

This page can be used to determine the type of ethical review required. This will be determined by the type of study, the participant group, and how participants are recruited/how data or tissue are collected.

The table below provides guidance to researchers on the specific ethics committees particular studies should be submitted to.

Ethics approval must be in place before the study begins.

Queries should be directed to the appropriate member of the Governance team via or

All studies taking place in the Faculty Science, Engineering and Medicine (excluding Psychology) that involve human participants, their tissue and/or their data (including those being conducted by staff and students/supervisors) that do not require NHS Research Ethics Committee approval are required to obtain Biomedical and Scientific Research Ethics Committee (BSREC) approval before the research can be undertaken. Research undertaken in the Faculty of Arts, Faculty of Social Science and the Department of Psychology should submit their ethics approval to Humanities and Social Sciences Research Ethics Committee (HSSREC).

*Which ethics committee needs to review studies involving human samples depends on where they are collected from, whether they are anonymous, and whether they have been collected with consent for use in research. Where samples have not been collected with consent for use in research, even when they are anonymous to the researcher, an application will need to be submitted to an NHS REC. Certain tissue banks can also issue ethical approval as part of the application process for obtaining human samples, providing these have been collected with consent for use in research. If studies involving samples falls under this category, please check the approval with the BSREC Secretary before the project begins.
