Current .co.uk domain statistics
There were 8,586,321 registered .co.uk domains in June 2026
That is the latest monthly figure published by Nominet at the time this guide was updated. The wider .UK registry included 9,042,101 third-level names and 1,463,045 second-level .uk names, a combined portfolio of 10,505,146 domains.
How is the .UK domain portfolio divided?
.co.uk: 8,586,321
The best-known third-level option for UK companies, organisations, projects and individuals.
Other third-level names
Together with .co.uk, names such as .org.uk and .me.uk brought the third-level total to 9,042,101.
Second-level .uk: 1,463,045
These names sit directly before .uk, such as example.uk rather than example.co.uk.
Total .UK: 10,505,146
This is the sum of Nominet’s third-level and second-level totals for June 2026.
What does the number tell a domain buyer?
.co.uk is well established
Millions of registrations make it a familiar UK address, but registration volume alone does not guarantee trust or search ranking.
Good names are still available
Availability changes continuously as names are registered, renewed and released. Search several clear, memorable alternatives.
Choose for your audience
A UK-focused business may prefer .co.uk or .uk. A global audience may also consider .com and other suitable extensions.
Check rights before buying
An available domain can still conflict with a trade mark or business name. Availability is not legal clearance.
Why has the total changed over time?
Registry totals rise and fall as businesses start, brands consolidate domains, promotions end, names expire and buyers choose newer extensions. Nominet also introduced registrations directly under .uk in 2014. A historic article may therefore show a larger or smaller number without being evidence of an error in the current table.
Where can I find the latest official figure?
Nominet operates the .UK registry and publishes a monthly table on its Reports and Statistics page. The table separates third-level registrations from second-level .uk registrations and provides annual extension totals.
.co.uk statistics questions
Does the .co.uk figure include .uk?
No. Nominet reports .co.uk and second-level .uk separately.
Is every registered domain an active website?
No. A domain can be parked, forwarded, used only for email, reserved for a future project or actively hosting a website.
Does an older domain automatically rank better?
No. Search performance depends on many signals, including useful content, links, reputation and technical quality.
How often is the figure updated?
Nominet publishes monthly registry statistics. Always check the reporting month.
Have a name in mind?
Check whether the .co.uk is available now
A live search matters more than an industry total because availability changes every day.
