The Integrated Research Application System (IRAS):
  • Is a single system for applying for the permissions and approvals for health and social care / community care research in the UK
  • Enables you to enter the information about your project once instead of duplicating information in separate application forms
  • Uses filters to ensure that the data collected and collated is appropriate to the type of study, and consequently the permissions and approvals required
  • Helps you to meet regulatory and governance requirements
IRAS captures the information needed for the relevant approvals from the following review bodies:
  • Administration of Radioactive Substances Advisory Committee (ARSAC)
  • Confidentiality Advisory Group (CAG)
  • Gene Therapy Advisory Committee (GTAC)
  • Health Research Authority (HRA) and Health and Care Research Wales (HCRW) for projects seeking HRA & HCRW Approval
  • Medicines and Healthcare products Regulatory Agency (MHRA)
  • NHS / HSC R&D offices
  • NHS / HSC Research Ethics Committees
  • Her Majesty's Prison and Probation Service (HMPPS)
  • Social Care Research Ethics Committee
Please help us to improve IRAS by sending your feedback to iras.queries@hra.nhs.uk. Your comments and suggestions will be included in the next review of the system.
