How can I apply for an extension of my existing agreement on data access for my research project in the service portal?

To extend your existing application, please submit an additional application within your existing application in the service portal. To do this, log in as usual and click on the relevant application under My applications. You can then submit a supplementary application via the "Supplementary agreements" button:

Select "Extension of data use" in the drop-down menu and enter the date until which your contract is to be extended (maximum 1.5 years).

Following this, you can check the application and submit it. We will process your supplementary application as usual and get back to.
