How to create a subdomain

May 9, 2026 • Domains & DNS

A subdomain is an extra address before your domain name, such as shop.example.co.uk or staging.example.co.uk.

What subdomains are used for

Testing or staging websites.

Separate landing pages.

Client portals.

Apps or tools connected to the main brand.

Step 1: Open cPanel

Log into cPanel at https://cpanel.hostluma.uk.

Step 2: Open Domains

Look for the Domains section. Depending on the cPanel layout, subdomains may be created from Domains or a Subdomains area.

Step 3: Add the subdomain

Enter the subdomain name, such as staging, shop or portal. Choose the correct domain if you have more than one.

Step 4: Confirm the document root

The document root is the folder where files for the subdomain will live. Do not point it at your main website folder unless that is intentional.

Step 5: Save and test

After creation, visit the subdomain in your browser. DNS and SSL may take time to become fully active.

Important notes

Ask Host Luma support before using a subdomain for a second WordPress installation, staging area or live customer-facing service.
