How to research a .uk domain before you buy it

Checking a .uk name before you buy it is mostly the same job as checking any domain, with three differences that catch people out. The public registration record will rarely tell you who holds the name. Disputes go through Nominet's Dispute Resolution Service, administered by WIPO since 7 July 2026, whose test looks at how a name is used as well as how it was acquired. And the two kinds of evidence buyers lean on most, third-party authority scores and reported sale prices, are weaker than they look.

This guide is about the name itself: what to check, where, in what order, and what each check cannot tell you. If the name comes with a trading website, the business side (content rights, traffic, revenue, customer data and the handover) is covered in our website due diligence checklist. This is general information, not legal advice; if a name matches someone else's brand, take advice before you buy.

Nominet's WHOIS shows a name's registration date and current status, the registrant's agent (the registrar the name is held through) and the name servers. What it does not normally show is the registrant. Since Nominet's data protection changes in May 2018, the .uk WHOIS has not displayed the registrant's name or address unless the registrant has given permission. For most .uk names you will not find the holder this way, and you should not expect to.

The lookup itself is changing. Nominet describes its port-43 WHOIS as end of life and says the service will cease on 9 February 2027. Its replacement is RDAP, the Registration Data Access Protocol, a WHOIS replacement built on modern web standards. Nominet provides a client at rdap.nominet.uk. We have not found a Nominet list of which RDAP fields are public, so treat the WHOIS consent rule as your guide and read what the lookup actually returns.

What to take from it

The registration date is the start of the current registration, not the age of the name. A .uk name that is cancelled is deleted from the register, so a name that dropped and was registered again can have a far longer history than its date suggests, and a seller's "established since" claim may belong to a previous holder. The archive check below is how you find out.

The status tells you about timing. A name past its expiry is on a clock: under the process in force today it can be renewed until 90 days after expiry and drops at 95, and that process changes on 9 February 2027. Our explainer on expired and dropping .uk domains covers the timeline and Nominet's daily drop list, which lists names that may drop and when.

Ask the seller to prove control. Because the record will not name them, ask them to make a change you specify, such as adding a DNS record with text you choose, and check that it appears. That proves control of the DNS rather than ownership, but someone who cannot do it cannot transfer the name to you.

Public web archives such as the Internet Archive's Wayback Machine are the main way to see what a name was used for before. The Internet Archive's own help suggests the pattern http://web.archive.org/*/www.yoursite.com/* to list everything it holds for a site. Its calendar colours each capture by the response the crawler received: "Blue means the web server result code the crawler got for the related capture was a 2nn (good); Green means the crawlers got a status code 3nn (redirect); Orange means the crawler got a status code 4nn (client error), and Red means the crawler saw a 5nn (server error)."

Read the history for three things. What it was: a business, a club, a blog, a parked page. When it was live: the years with real content, and any long gaps. How it ended: the last chapter is where trouble usually shows, such as pages in a language unrelated to the name, casino or pharmacy content, or a hacked site full of links.

Absence of captures is not absence of history. The archive says plainly that it does not collect everything: "Pages may not be archived due to robots exclusions and some sites are excluded by direct site owner request." In 2017 the Internet Archive also described how a robots.txt block added when a site became a parked domain "has historically also removed the entire domain from view in the Wayback Machine". A thin record can mean a quiet name, or a hidden one.

Archive presence is not permission. The Internet Archive "does not make guarantees as to the copyright status of items", and buying a name does not buy the words and pictures of the site that used to sit on it.

Green dots in the archive calendar, or 3xx status codes in the archive's capture index, mean the name was redirecting somewhere when it was crawled. Some redirects are innocent: a business rebranded and pointed its old name at the new one. Others are worth questions.

A name that spent years redirecting to its owner's new site was doing what Google's site-move guidance describes: redirects there are how a site's signals are transferred to the new URLs. If that is this name's last chapter, much of the standing it had was being passed on, not kept. A name that redirected to an unrelated site, or was one of several names pointing at the same page, fits a different pattern. Google's spam policies list doorway abuse, with the example of "Having multiple domain names or pages targeted at specific regions or cities that funnel users to one page", and sneaky redirects, which "show users unexpected content that doesn't fulfill their original needs". Neither tells you how Google treats this particular name, but both tell you what to ask the seller.

Two government searches tell you whether the name is someone else's brand.

Trade marks. The Intellectual Property Office's trade mark search lets you "check if a similar trade mark to your brand already exists in the UK" and "find out who owns a trade mark", searching by number, owner, or keyword, phrase or image. A registered UK mark protects its owner in the UK and the Isle of Man and lets them "take legal action against anyone who uses your brand without your permission". Look for marks that match or resemble the name, and note what goods and services they cover against what you plan to do.

An empty search does not settle it. The Trade Marks Act 1994 provides that nothing in it "affects the law relating to passing off", which protects an unregistered business's goodwill. An HMRC manual sums up its elements as "the classic trinity of reputation (or goodwill), misrepresentation and damage". A name that a trading business has used for years can carry that goodwill without ever being registered.

Company names. Companies House gives "some details about a company for free", including its registered address, date of incorporation, current and resigned officers, previous company names and insolvency information. Use it to answer the questions that matter for a name: is the business that used it still trading, under this name or another? Was it dissolved, or did it go into insolvency? Has another company since registered the same name?

Disputes over .uk names are decided under Nominet's own Dispute Resolution Service (DRS). From 7 July 2026 the service is administered by WIPO: "Disputes filed on or after July 7 will be administered by WIPO", while those filed with Nominet before then continue with Nominet. According to GigaLaw's summary of the change, the DRS Policy and its fees are unchanged.

The test is whether the name is an Abusive Registration, which WIPO's summary of the policy gives as a name that "(i) was registered or otherwise acquired in a manner which, at the time when the registration or acquisition took place, took unfair advantage of or was unfairly detrimental to the complainant's rights; or (ii) is being or has been used in a manner which has taken unfair advantage of or has been unfairly detrimental to the complainant's rights."

The second limb is the one buyers overlook. It is about use. A name you acquire in good faith can still be found abusive if you later use it to trade on someone else's rights, for example by keeping a former business's branding or letting visitors think the old firm is still behind the site. So the question is not only whether the name is safe to buy, but whether what you plan to do with it is. If the parties do not settle in mediation within ten working days, they are invited to pay for an expert decision.

Backlink tools show you which sites link to a name and estimate how much those links are worth. Use the first part and be careful with the second. When Google introduced its expired domain abuse policy in 2024 it added a direct warning: "some third-party services provide 'reputation' or 'authority' scores for sites. These don't correspond to any of Google's own signals nor come from Google." A score is one vendor's estimate, not a measurement of how Google sees the name.

The links themselves are better evidence, and they are worth checking one by one at the top of the list. Are the linking pages real and still there? Ahrefs' study of link rot (2022, updated 2024) found that, since January 2013, 66.5% of the links pointing to the 2,062,173 websites it sampled had rotted, so a large historic link count may be mostly gone. Are the linking sites about the same subject as the name? What does the anchor text say? Anchors in an unrelated language, or about casinos, loans or pharmacy, usually date from a spam chapter in the name's past.

Then be honest about why you want the links. Google's spam policies treat buying an expired name and repurposing it mainly to manipulate rankings with low-value content as expired domain abuse, while Google also says that reusing an old name for a new, original site built for people is fine. Our guide to repurposing an old domain safely sets out where that line sits.

Comparable sales help you price a name, if you know what each figure is. Two cautions cover most of the problems.

A closing bid is not a price. An auction's closing bid where payment was never confirmed tells you what someone offered, not what anyone paid. DropOps excludes these from its price evidence: in our study of UK sales, 141 closing bids from one venue were left out for exactly this reason.

Know the channel and the label. Of the 24,675 UK sales that met our evidence standard, every one was a drop-auction result reported by a single venue, DomainLore. The venue labels most of them as verified; DropOps records them as reported prices that it has not itself verified. They describe what recently dropped names fetched at auction, which is not the same market as a name an owner is still using and has no need to sell. Our analysis of what 24,675 UK auction results show goes through the figures and their limits, and the recorded sales are on sold domains, with the aggregate picture on market reports.

Whether Google has taken manual action against a name is not something you can check from outside. Search Console shows it, and Search Console belongs to whoever can prove control of the domain: for a Domain property, by adding a DNS record at the domain provider. Google's site-move guidance tells the buyer of a domain to "make sure it's clean of any outstanding issues from the previous owner", and names two things to look for: a manual action for previous spam, which is fixed with a reconsideration request, and URL removals left over from the previous owner, "especially a site-wide URL removal".

Before you buy, you are reading indirect evidence: the archive history, the anchor text of the links, and whether a search for the name turns up pages that match its history. If a site has been running on the name, ask the seller to show you its Search Console property, including the manual actions and removals pages; the website due diligence checklist covers that access in more detail. If they cannot or will not show it, price the uncertainty in, or walk away.

A seller offers example-bakery.test as a short, memorable .co.uk-style name, "established 20 years" with "over 300 linking domains". On the surface it looks clean. The checks tell a different story.

1. Registration record. The registration date is two years ago. The 20 years belong to an earlier registration.
2. Archive. A family bakery used the name for about 14 years. Then the captures change: two years of pages in an unrelated language, then a run of green redirect captures pointing at an unrelated shopping site.
3. Companies House. The bakery's company is still active, trading from a new domain.
4. Trade marks. The bakery registered its name as a word mark.
5. Links. Most of the 300 linking sites date from the bakery years, many of the linking pages no longer exist, and the newest links carry casino anchor text.

The verdict: the name's history and goodwill belong to a business that still trades and holds a mark; the surviving links point to that business, not to the name; and its last chapter matches the pattern Google's spam policy describes. Any use that leans on the old bakery's reputation risks the second limb of the DRS test. The honest price for this name is the price of a two-year-old registration with a liability attached.

Do the cheap checks that can end the conversation first, and leave the slow ones until the name has earned them.

If the name comes with a working website, the last step is a project of its own, and the website due diligence checklist takes over from here. For the name itself, you can look up a .uk name on DropOps, browse dropping and dropped names in Discover, and compare against recorded UK sales.
