Once the application is correct and complete it should be submitted to Research Services at least 5 working days before the deadline, as detailed in the Royal Society guidelines.
Note: For applications via Flexi-Grant the deadline for submission of your application and the completion of support statements from your head of department and nominated referees will fall on the same date, which is a departure from the previous process employed by the Royal Society via eGAP2. Research Services will not be able to approve your application for submission until the support statements have been provided.
