How to Register a Domain Name

Everything you need to know about choosing and registering the right domain name for your UK business.

YCN Editorial Team

Your domain name is your address on the internet — it's what customers type to find you, what appears in your email address, and a key part of your brand identity. Unlike a company name, anyone can register any available domain name regardless of whether a company with a similar name exists. This creates both opportunity and risk.

Domain Names vs Company Names

These are completely separate systems managed by different bodies:

Feature Company Name Domain Name
Managed by Companies House Domain registrar / Nominet (.co.uk)
Who can register UK residents / businesses Anyone worldwide
Cost £50 (one-off) £5–£20/year (ongoing)
Exclusivity Prevents similar registrations First-come, first-served globally
Legal protection None inherently None — need a trade mark for that

Step 1: Choose Your Domain Name

Ideally, your domain name should match your company name (or be as close as possible). A few principles:

  • Keep it short and memorable — shorter domains are easier to type, share, and remember
  • Avoid hyphens and numbers — they are harder to communicate verbally ("is that a hyphen or underscore?") and reduce trust
  • Make it easy to spell — if customers have to guess the spelling, you'll lose traffic
  • Match your brand — your domain should reinforce your company name, not conflict with it

Step 2: Choose a Domain Extension

The extension (also called a TLD — top-level domain) that's right for you depends on your audience and business:

.co.uk
The standard for UK businesses. Signals a local presence and builds trust with UK customers. Managed by Nominet.
.com
The global standard. Ideal if you trade internationally or want a broader audience. Harder to get the one you want.
.uk
The shorter alternative to .co.uk, introduced by Nominet. Growing in popularity but .co.uk still dominates.
.io
Popular with tech startups. No geographic meaning but associated with innovation. More expensive (~£30+/year).
.org
Traditionally for non-profits and charities. Generally not appropriate for commercial businesses.
.net
Originally for network providers. Now a secondary option when .com is taken. Rarely ideal.
Register multiple extensions

Many businesses register both .co.uk and .com (and sometimes .uk), pointing all of them to the same website. This prevents competitors or cybersquatters from registering variations of your name. The cost is minimal compared to the risk.

Make sure the company name matches

Once you have a domain, you need the matching company name. Browse our pre-registered UK Limited names — short names with matching domain potential.

Step 3: Check Availability

Use a domain registrar's search tool to check whether your domain is available. Most registrars show results for multiple extensions simultaneously. Some popular UK registrars include:

  • 123 Reg — popular UK registrar, good for .co.uk
  • GoDaddy — large US-based registrar, wide extension support
  • Namecheap — competitive pricing, good interface
  • Cloudflare Registrar — no markup on wholesale prices, good for tech-savvy users
  • Google Domains / Squarespace — simple interface, integrated with Google services

Step 4: Register the Domain

Once you've found an available domain, registration takes a few minutes. You'll need to provide:

  • Your name and contact details (required for the WHOIS record)
  • Payment for the first registration period (typically 1 or 2 years)

WHOIS privacy: By default, your contact details are publicly searchable via WHOIS. Most registrars offer free or paid WHOIS privacy protection, which replaces your details with the registrar's proxy information. For .co.uk domains, Nominet's opt-out applies automatically for individuals (not businesses).

Auto-renewal: Set up auto-renewal from day one. If you forget to renew, your domain lapses and can be registered by someone else — including domain squatters who will sell it back to you at a premium.

Step 5: Configure DNS and Email

Once registered, you'll need to configure the domain to do something useful:

  • A record / CNAME — points the domain to your web hosting server's IP address
  • MX records — routes email for your domain to your email provider (e.g. Google Workspace, Microsoft 365, Zoho Mail)
  • SPF / DKIM / DMARC — email authentication records that prevent your email being marked as spam

Your web host or IT provider can usually help configure these settings.

What If the Domain Is Already Taken?

If your preferred domain is already registered, you have several options:

  • Contact the owner — look up the WHOIS record and reach out. They may be willing to sell.
  • Use a domain broker — services like Sedo or Afternic can negotiate on your behalf for premium domains.
  • Choose an alternative extension — if .com is taken, .co.uk may be available.
  • Adapt the name — adding a word like "get", "use", or "uk" to the domain (e.g. getbrandname.com).
  • Wait for it to expire — use a domain backorder service to automatically register it the moment it lapses.
Domain ≠ Company Name ≠ Trademark

Registering a domain gives you no rights over a company name or a trade mark. And registering a company name doesn't give you rights to the domain. Truly protecting your brand requires all three: the company name, the domain, and where appropriate, a registered trade mark. See our guides on what is a trademark and how to register a company.
