NHS ethical review

The UK has a range of bodies which have roles in regulating different aspects of health research in humans. The Health Research Authority (HRA) provides Research Ethics Committees and the Confidentiality Advisory Group, which review applications to undertake certain types of research. They also work with other bodies to coordinate the overall system for regulation and governance of research.

Determining whether NHS ethical review is required

This decision tool will help you to determine if your study requires approval from an NHS Research Ethics Committee (REC). If NHS REC approval is required, University of Leeds ethical review is not normally needed in addition.

There is also a decision tool to help you decide whether or not your study is research. You may also find it helpful to refer to the guide for Clinical Audit, Research and Service Review.

More detailed information, including some examples, is available in the document: Does my project require review by a Research Ethics Committee?

Refer to the Governance Arrangements for Research Ethics Committees (GAfREC) guidelines for further information.

Once you have NHS ethical approval in place please inform the relevant Faculty/School Research Ethics Committee.

HRA Confidentiality Advisory Group (CAG) approval is required for patient identifiable information collected without explicit consent.

Applying for an amendment

Applying for NHS REC review 

The Integrated Research Application System (IRAS) is a single online system for applying for permissions and approvals for health and social care/community research in the UK.

In 2015 the HRA introduced a new combined process for applying for the various permissions and approvals called HRA Approval. This new approval process is being rolled out in phases. Some studies taking place solely in England are now eligible to apply for HRA Approval.

Applications for HRA Approval are made via IRAS. Guidance for applicants is available in IRAS and via the HRA website.

Central Booking Service (CBS), has been introduced to cover all bookings for NHS Research Ethics Committees in the UK. This replaces the previous Central Allocation System, Proportionate Review Allocation Systems and Local Allocation Systems.

Information about the Proportionate Review Service - for low-risk research studies.


It's important to explain to research participants how their personal data will be used, and what their rights are. Privacy Notices need to be concise, easily accessible to participants and easily understandable.


NHS management permission (Research and Development (R&D) approval) 

The Leeds R&D Office

Leeds Teaching Hospitals Trust Research and Innovation

For enquiries about the R&D approval process or to confirm whether a research proposal is classed as research or audit/service evaluation, you can contact the relevant team in the Research and Innovation Department.

HRA Guidance on Student Research

A comprehensive guidance document on student research is now available on the HRA website. This collates and updates previous guidance from NRES, as well as relevant guidance developed in consultation with the NHS R&D Forum within the Integrated Research Application System (IRAS).

Social care research

Most social care research needs NHS Social Care REC review. The SCREC only reviews adult social care studies, those involving children can still be reviewed by a University ethics committee.  The SCREC can also review research within the NHS that uses social science or qualitative methodology, provided that the research does not involve any clinical interventions or changes to clinical care.  Applicants are advised to contact the SCREC for advice on whether SCREC review is required or if University review would be appropriate.
