The short answer
Is .co.uk a good domain extension?

Consider another extension when
- There is no UK operation
- The matching .uk is an active competitor
- The brand needs one neutral international primary address
Research brief
The .co.uk facts that change the decision
This page separates registry policy, public market evidence and registrar pricing. A sample is labeled as a sample; a rule is labeled as a rule; and a checkout quote is never presented as a registry statistic.

Who uses .co.uk?
These are recognizable examples, not endorsements or traffic rankings. The useful pattern is how broadly the extension works across industries.
Availability without guesswork
How to find a strong available .co.uk
Treat availability as the start of the decision, not the finish. A usable name also needs to be easy to communicate, defensible and fairly priced.
- 01
Start with a name that earns .co.uk
Check the matching .uk, trademarks and spoken pronunciation; visitors may type either UK format from memory.
- 02
Search the exact label first
Keep the search scoped to this extension, then compare the exact label with closely related endings before accepting a spelling compromise.
- 03
Check rights and pronunciation
An available result is not trademark clearance. Say the name aloud, check local implications and review the registrar’s final eligibility rules.
Pricing explained
What does a .co.uk domain cost?
The useful number is the full cost of ownership, not the largest promotional figure on a registrar banner.
Price coverage is not available for .co.uk yet. This page does not invent a number. A verified row will appear after the next registrar collection or an admin-approved override; the partner checkout remains the final source for the exact name, premium status, tax and renewal terms.
Compare the full .co.uk ownership cost
Compare .co.uk renewal and transfer with .uk and .com; the registrar confirms the exact quote.
