Domain Names: What is Domain Registration?

Domain Registration is how you claim a unique web address for your website — like your-big-idea.co.uk or your-big-idea.com.

Once it’s registered, that name is yours to use for a set period (usually a year or more), as long as you renew it when needed.

Think of it as claiming your space on the internet — no one else can use that exact name while it’s registered to you.

Why domain registration matters

Your domain name is often the first thing people see when they come across your business. It helps customers find you, builds trust, and gives your brand a more professional feel.

With a domain in place, you can build a website with a tool like 123 Reg Website Builder, and set up a professional email address that matches your brand.

Choosing the right domain

A strong domain name should be:

✓ Easy to remember and spell
✓ Relevant to your business or brand
✓ Short and simple where possible
