How to install a Let’s Encrypt SSL certificate

Applies to cPanel Plesk

Quick answer

In cPanel, open SSL/TLS Status in the Security section and click Run AutoSSL to install Let's Encrypt certificates on every eligible domain. In Plesk, open SSL/TLS Certificates from the domain's Dashboard, click Install, then click Get it free. Let's Encrypt certificates renew automatically every 90 days. Wildcard certificates in Plesk do not renew automatically, so a standard certificate suits most sites.

Let’s Encrypt provides free SSL certificates that encrypt connections between your visitors and your website. Installing one protects sensitive data like login credentials and payment information from interception.

You will install a Let’s Encrypt certificate through either cPanel or Plesk depending on your hosting platform. The process takes a few minutes and your certificate renews automatically every 90 days.

Before you begin

You need access to your cPanel or Plesk control panel.
Wildcard certificates require DNS validation, which can take up to 48 hours to propagate.
We recommend standard certificates for most sites as they renew automatically.

Install with cPanel

cPanel uses AutoSSL to install and manage Let’s Encrypt certificates. This tool checks your domains regularly and installs certificates where needed.

Log in to cPanel.
Access your control panel at yourdomain.co.uk/cpanel using your hosting credentials.
Open the SSL/TLS Status tool.
Scroll to the Security section and click SSL/TLS Status.

AutoSSL installs certificates for all eligible domains and schedules automatic renewals. Your domains now load over HTTPS with valid certificates.

Install with Plesk

Plesk provides Let’s Encrypt integration through its SSL/TLS certificate manager. You select which domains to secure and Plesk handles the installation.

Log in to Plesk.
Access your control panel through the client area login shortcut or directly at yourdomain.co.uk:8443.

Plesk installs the certificate and configures automatic renewals. Your domain now accepts HTTPS connections with a valid certificate.

Wrapping up

Your Let’s Encrypt SSL certificate is now active and encrypts all connections to your website. The certificate renews automatically before it expires, keeping your site secure without manual intervention.

We recommend forcing HTTPS connections to prevent mixed content warnings and ensure all visitors use the encrypted connection. Our web hosting includes Let’s Encrypt support across all plans.
