.co.uk is the commercial zone of the United Kingdom's namespace, managed by Nominet, the Oxford-based registry that has run .uk since 1996. It is among the world's largest country-code zones, with millions of active names, and remains the address British consumers most readily associate with a UK business.
For anyone selling to British customers, that recognition is the asset. A Sheffield trades firm, a London ecommerce brand, or a Nigerian exporter courting UK buyers all benefit from an ending that signals domestic pricing in pounds, UK consumer-rights compliance, and deliverable-by-Friday logistics. Irish and Dutch companies with British customer bases routinely run a co.uk storefront beside their home domain for the same reason.
ATCOS Domains provides co.uk on GoDaddy's registrar platform with Nominet's mechanics, IPS tag transfers rather than auth codes, handled through the dashboard. Registration terms run up to ten years, and bundling UK-focused hosting, email, and SSL means a British market entry can be live within a day of the idea.
Live .co.uk pricing — including multi-year and renewal rates — is shown at checkout before you commit. No surprises, no checkout-only fees.
Who .co.uk is built for
- British SMEs choose co.uk over generic endings because domestic shoppers filter search results by it when they want local stock and returns.
- Nigerian and Kenyan exporters selling into Britain run co.uk storefronts so UK buyers see local presentation, sterling pricing, and familiar trust signals.
- Irish businesses serving Northern Ireland and Great Britain operate a co.uk alongside their .ie to keep each market's messaging cleanly separated.
- Freelancers and contractors in the UK gig economy present co.uk portfolios that agencies and procurement teams read as established and invoice-ready.
- Web agencies managing British client portfolios appreciate Nominet's fast tag-change transfers, which make consolidating a client's scattered domains genuinely painless.
Nominet places no residency or nationality restriction on co.uk; registrants worldwide qualify. Registrar transfers use Nominet's IPS tag system rather than authorisation codes, and while Nominet itself imposes no 60-day transfer lock, individual registrars may apply their own post-registration holds.
.co.uk — Frequently asked questions
Who or what is Nominet?
Nominet is the official registry for .uk and its zones, a membership-based company founded in 1996 and headquartered in Oxford. It runs the technical registry, sets .uk policy, and operates a well-regarded dispute resolution service for domain conflicts. Registrars, including the GoDaddy platform behind ATCOS Domains, hold Nominet accreditation and manage registrations on customers' behalf.
How do co.uk transfers differ from .com transfers?
Instead of unlocking a domain and exchanging an authorisation code, a co.uk moves when the current registrar changes its IPS tag to the new provider's tag. The change usually takes effect quickly and Nominet does not charge for it. There is no registry-imposed 60-day wait, though your existing registrar's own release process can add steps.
What happens if my co.uk domain expires?
Nominet allows a window after the renewal date in which your registrar can still renew the name; the domain is typically suspended during part of this period, taking your website and email offline, and is cancelled and released roughly ninety days after expiry. Renewing promptly or enabling auto-renewal avoids the suspension entirely.
Should I register .uk as well as .co.uk?
Nominet opened shorter second-level .uk names in 2014, and the reservation rights that protected matching co.uk holders ended in 2019, so both now sell freely. Registering both and redirecting one prevents a competitor or bad actor from trading on your name with the sibling address. For most British audiences, co.uk remains the primary choice.
