.uk domain — meaning, price and how to register

What does .uk mean?

The .uk extension is the national domain of the United Kingdom, sitting in the IANA root zone since 1985. For most of its life people did not register .uk directly at all — they registered under a labelled second level that said what kind of site they ran: co.uk for businesses, org.uk for organisations, gov.uk for government, ac.uk for universities. That structure is one of the most recognisable on the internet, and co.uk in particular became shorthand for "a British website". In 2014 the registry, Nominet, opened up shorter direct registrations such as brand.uk alongside the older pattern.

The result is that .uk is both old and modern: a deeply trusted ccTLD with a forty-year track record, plus a tidier short form for brands that want it. It is one of the largest country codes in the world by registration count.

Who uses .uk?

Practically every British business, charity, public body and media outlet has a .uk presence — the BBC at bbc.co.uk and the UK government's single domain gov.uk are the obvious landmarks. Local shops, tradespeople, professional firms and bloggers lean heavily on co.uk because UK visitors instinctively trust it for a domestic service. Direct .uk is increasingly used by newer brands that want a crisp, short address.

For a company selling to British customers, a .uk address is close to expected. It says "we are here, in your country", which matters for everything from delivery to consumer-rights confidence.

.uk registration rules and requirements

.uk is essentially open — there is no nationality test and no requirement to be a British company. You do not have to live in the UK to own one. The single hard rule Nominet enforces is that the registrant record must contain a valid UK postal address for service. In practice that is easy for UK residents and businesses, and overseas registrants typically satisfy it using a UK address they control or an address service offered by some registrars. Beyond that, registration is first-come, first-served, and the holder of a co.uk normally has the priority right to claim the matching direct .uk.

How much does a .uk cost?

.uk and co.uk are inexpensive, generally around $9 per year (UK registrars usually quote in pounds, often a little less). There is no premium tier on standard names, renewals are stable, and the two-year minimum that historically applied has long gone. It is a cheap, low-drama domain to keep.

Is .uk good for SEO?

For a UK audience, yes — a .uk or co.uk address is a clear geo-targeting signal that helps search engines associate the site with Britain, which is exactly what you want if your market is domestic. There is no ranking penalty and no hidden boost: the benefit is relevance to British searchers, not a thumb on the algorithmic scale. The one thing to weigh is that the same UK signal can make it harder to rank elsewhere, so a global brand might still prefer .com. Our comparison guide covers the trade-off.

.uk vs alternatives

The everyday choice in Britain is direct .uk versus the venerable co.uk, and most established firms still keep both. Against the wider field, .uk competes with .com (global recall, but the .com is often taken) and the pan-European .eu for businesses trading across the continent. Compared with neighbouring national codes such as .de or .fr, .uk's address-only rule is one of the more relaxed registration regimes in Europe. For US-facing sites, .us plays the equivalent national role.
