Everything you need to know about choosing and registering the right domain name for your UK business.
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.
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 |
Ideally, your domain name should match your company name (or be as close as possible). A few principles:
The extension (also called a TLD — top-level domain) that's right for you depends on your audience and business:
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.
Once you have a domain, you need the matching company name. Browse our pre-registered UK Limited names — short names with matching domain potential.
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:
Once you've found an available domain, registration takes a few minutes. You'll need to provide:
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.
Once registered, you'll need to configure the domain to do something useful:
Your web host or IT provider can usually help configure these settings.
If your preferred domain is already registered, you have several options:
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.
Make sure your company name matches. Browse our portfolio of pre-registered UK Limited company names — many short, clean names still available.
