Because of the technical knowledge required to install and setup a certificate we do not permit users to install there own.
Before a SSL certificate can be install on your site a dedicated IP address will need to be assigned to you. If your site is live this will cause some downtime while the new IP address resolves to your site.
After the IP address has resolved correctly, we will process to install your SSL certicate.
We use Comodo SSL certificates which are valid in over 99% of all browsers.
