Overview:
You can enable auto-renew on domain names within Domain Panel. This will automatically attempt to renew a domain name when it is within 30 days of its expiry date. Auto Renew requires that you have a credit card stored in your Domain Panel account. You can add a credit card to Domain Panel by following the guide here.
Method:
Log into Domain Panel (NB: if you're unsure, you can follow our guide).
Click on the "Domains" tab on the left-hand side panel.
Find your domain name on the page, or search for the domain using the search bar.
Toggle the "Auto Renew" option from "Disabled" to "Enabled".
