What Is a Domain Name Registrar and Which Should You Use?

A domain name registrar is a company accredited to sell and manage domain names — the addresses people type into their browser to reach a website. When you buy a domain name, you are purchasing the exclusive right to use that address for a set period, typically one to ten years. The registrar manages this registration on your behalf and provides the tools to configure your domain's DNS settings.

Choosing a registrar is one of the earliest decisions in building a website, and while it is possible to transfer a domain to a different registrar later, picking a reliable one from the start saves time and hassle. There are hundreds of registrars to choose from, ranging from global giants to small independent operators.

How Domain Registration Works

Domain names are managed within a global system overseen by ICANN (the Internet Corporation for Assigned Names and Numbers). Registrars are companies that ICANN has accredited to sell domain registrations. When you register a domain through a registrar, they update the central registry for that top-level domain — .co.uk, .com, .org, and so on — with your ownership details.

Your registration gives you control over the domain's DNS records — the settings that tell the internet where to find your website and where to deliver your email. You configure these through your registrar's dashboard. Pointing your domain to a hosting provider involves updating the nameservers or A record to the values your host provides.

What to Look for in a Domain Registrar

Price is an obvious factor but should not be the only one. Some registrars offer very low first-year prices and then charge significantly more for renewals — always check the renewal price before registering. Look for a registrar that includes free WHOIS privacy protection, which hides your personal contact details from public domain lookup databases. Many registrars now include this as standard; some still charge extra.

A clean, easy-to-use DNS management interface is important, particularly if you need to configure MX records for email, CNAME records for services like Google Workspace or Mailchimp, or TXT records for domain verification. Customer support quality matters most when something goes wrong — check reviews and verify whether live support is available. Reputable registrars for UK businesses include Namecheap, 123-reg, 1&1 IONOS, and Easily.

Should You Register Your Domain With Your Hosting Provider?

Many hosting providers also offer domain registration, which is convenient — everything is in one place. However, keeping your domain and hosting with different providers is generally recommended because it prevents vendor lock-in. If you want to switch hosts, having your domain at a separate registrar means you simply point it to the new host without negotiating a domain transfer.

At Xpose in Norwich, we recommend clients register their domain with a dedicated registrar and keep their hosting separate. This gives clients full control over their most valuable digital asset — the domain name — independent of which hosting or web design provider they use. It also makes it easier to switch providers for hosting without disrupting your email or affecting your domain ownership.
