When you top up your account, these funds will remain available for 18 months after you last logged in or took any action on the account (e.g. approving a submission).
Please note that after 18 months of inactivity we may close the account or charge a 'dormant account fee'. Further information can be found in section 5 of our Researcher Terms and Conditions.
Feel free to get in touch with our Support Team if you have any questions or concerns about this.
