Start with the people you serve. A .co.uk address makes a UK focus clear; .com can suit a brand serving several countries. Choose a name you can explain easily, check both registrations and renewals, and use one primary website address if you own both.
Before you begin
- Your main customer countries today
- A shortlist of complete addresses
- Registration and renewal prices for each name
- A plan for any extra address you register
Match the address to your audience
A local service business may prefer an address that immediately identifies its UK focus. A business taking orders from several countries may prefer an address without a country ending. These are practical branding choices: ask whether the complete address makes sense to your customers, rather than choosing an extension because it sounds fashionable.
Nominet identifies .co.uk with commercial purposes. A .com address is a generic extension. Neither registration tells a customer where your products can be shipped or which markets you serve; make that information clear on your website.

Compare the same name, not just the ending
Write the exact address you would use under each extension. If the matching .com is unavailable, compare a clear .co.uk with your actual alternative .com spelling. Adding several words or separators just to obtain a particular ending can make the address harder to remember.
Test the address aloud with someone who has not seen it written. Then try an email address in the same format, such as hello@example.co.uk. Can they repeat the spelling and ending correctly? Use example addresses for the test; an available result still needs a live registration check.
| Question | .co.uk | .com |
|---|---|---|
| What does the ending communicate? | A UK connection | No particular country |
| Where does it fit your plans? | A brand focused on the UK | A brand serving several countries |
| What should you compare? | The complete name and ongoing cost | The complete name and ongoing cost |
| Does the ending guarantee rankings? | No | No |
Understand the search implications
Google treats a country-code domain as one signal of the audience a website targets. A generic extension such as .com does not supply that country signal. Google can also use the site's language, local address, currency and other information to understand its audience.
That does not make .co.uk an automatic ranking win or .com a barrier to reaching UK customers. Publish useful pages for the people you serve and make the site easy to use. Filling a name with search phrases is not a shortcut either: Google's exact-match domain system limits undue credit for query-matching names.

Decide whether a second registration has a job
Owning both endings can be useful when each has a clear purpose, such as directing people who type the alternative to your main website. It creates two ongoing renewals and does not give you control of every spelling or extension. Check the extra cost against the likely benefit before adding names.
Registering one address does not include the other. Availability can differ, and an already registered name may require a separate sale or may not be available to you. NameUK's standard self-service search excludes premium names and does not arrange aftermarket purchases.
Use one primary website when both serve the same site
Choose the address you will put on invoices, social profiles and email signatures. Ask your website provider to set up a permanent redirect from the alternative address to that primary website, preserving relevant page paths. Google recommends permanent server-side redirects when the destination is intended to stay preferred.
A DNS record alone does not create that redirect. The alternative address needs a working web service and HTTPS configuration. Email is a separate decision: if you want mail sent to both domains to arrive, configure that with your email provider rather than assuming the website redirect handles it.

Compare renewals before making the final choice
For each shortlisted address, record the first-year price and the recurring renewal price. For a simple three-year comparison at unchanged annual prices, add one registration year and two renewals. Multiply that comparison by the number of names you intend to keep; future prices can change.
Finally, name the person responsible for the registrar account, renewal messages and payment. A well-chosen address is useful only while the registration remains under your control. Compare NameUK registration and renewal prices, then review the current domain quote before paying.
Extension rules and provider processes can change. Check the current registrar instructions before a registration, transfer or renewal.
