Registering both .co.uk and .uk can make sense when both names matter to your brand and the ongoing cost fits your budget. They are separate registrations: holding one does not automatically give you the other or connect them to the same website.
Before you begin
- Search both names individually.
- Choose one primary address.
- Plan both renewal costs.
Choose your primary address first
Decide which ending you want customers to see on your website, invoices and email. Consistent use is easier to explain than switching between two addresses without a plan. A shorter .uk may suit one brand, while another may prefer the familiar .co.uk format.
Try both aloud with the actual name. Think about how a customer will type it after hearing it on the phone. This is a practical branding choice, not a promise that one ending will outrank the other in search.
Check availability separately
Search the full .co.uk and .uk names individually. They can be registered to different people and can have different availability. Do not assume that a successful purchase of one has reserved the other while you decide.
If both are available and useful, review both order lines before payment. The registration term belongs to each name. Check that the registrant details are correct on both, then keep both registration confirmations and expiry dates.
NameUK’s current registration and renewal offer
For one .co.uk name, current annual renewal is £9.99. Count every additional registration separately and check its own ending’s renewal price.
Give the second domain a job
For a single website, the secondary address usually needs a deliberate redirect to the primary address. Arrange that at a web host or forwarding service. Merely pointing a CNAME record at the primary hostname does not create an HTTP redirect.
Consider email separately. If customers may write to the other ending, ask your email provider how it handles domain aliases or extra domains. A website redirect does not cause mail addressed to the secondary domain to arrive at your main inbox.
Budget for the pair
Each name has its own registration and renewal. Compare the benefit of the second address with the cost of keeping it over the period you expect to trade.
- Record both full domain names and expiry dates.
- Set one primary website address and test the secondary redirect.
- Decide whether the second domain needs email routing.
- Include both annual renewals in your business budget.
