Sooner or later almost every UK business owner meets a phrase that sounds like it belongs in a spy film: the IPS tag. It usually turns up at an awkward moment, when you are trying to move your .uk domain away from an old provider and someone tells you the transfer cannot happen until the tag is changed. If you have no idea what that means, you are in very good company; we get asked about this constantly, normally by someone who just wants their website moved and cannot understand why it involves jargon.

The good news is that it is far simpler than it sounds, and once you understand it you will never be confused by a .uk domain transfer again.

What an IPS tag actually is

Nominet is the organisation that runs .uk domain names, including .co.uk, .org.uk and plain .uk. Every registrar that can manage .uk domains, whether that is a big hosting company or a small reseller, has a short identifying code registered with Nominet. That code is the IPS tag.

Your domain has exactly one IPS tag at a time, and it tells Nominet which company is currently responsible for managing that domain. Think of it as the name on the file rather than the name on the deeds. You still own the domain; the tag simply records who is looking after the paperwork.

That distinction matters more than anything else in this article. Changing the tag does not change who owns the domain.

Why the IPS tag matters when you move providers

Here is where it becomes practical. If you decide to move your .uk domain from one provider to another, the receiving company cannot simply reach out and take it. The transfer only works if your current provider changes the IPS tag to the new provider’s tag. Until that happens, the new provider sees a domain that is not theirs to manage and can do nothing with it.

So a .uk transfer is really a two-step conversation: you ask the old provider to release the domain by changing the tag, and the new provider then accepts it at their end. Nothing moves until step one happens.

This is also why .uk transfers feel different from .com transfers, which use authorisation codes instead. If you have moved a .com before and are expecting the same process, the difference can be genuinely disorienting.

What changing your IPS tag does and does not affect

Worth being crystal clear, because this is where the worry usually sits:

• Ownership: unchanged. The registrant details recorded with Nominet stay exactly as they are.
• Your website: unaffected by the tag change itself. Your site keeps loading, because that is controlled by your DNS and hosting, not by the tag.
• Your email: also unaffected by the tag change alone. Again, that is DNS.
• Who can manage the domain: this is the bit that changes. Control moves to the new registrar.
• Renewal and billing: this moves too, so you will start paying the new provider rather than the old one.
• Expiry date: normally unchanged, though some registrars add a year when you transfer in.

The risk in a domain move is almost never the tag change; it is forgetting to recreate your DNS records at the other end.

How to change your IPS tag, step by step

The exact buttons differ by provider, but the shape of the process is always the same.

Find out who currently holds your domain

If you are not sure, look your domain up on Nominet’s own WHOIS service. It will tell you the current registrar and the tag. This is genuinely useful when a domain was registered years ago by a developer who has since vanished.

Get the new provider’s tag

Ask your new host or agency for their IPS tag. It is usually a short string of capital letters, something like EXAMPLEHOST. They will supply it happily; it is not sensitive information.

Log in to your current provider’s control panel

Look for domain management, then an option along the lines of “change IPS tag”, “transfer out” or “release domain”. Some providers hide it a little, because releasing a domain means losing a customer.

Enter the new tag and confirm

Type the tag exactly as given, including capitals. Confirm the change. Most providers will email you to verify, so keep an eye on the inbox attached to the domain.

Tell the new provider to accept it

The domain will now be sitting with the new registrar’s tag, waiting. They usually need to accept the incoming transfer, and often to take payment for the renewal. Do not skip this; a released domain that nobody accepts is a domain in limbo.

Check your DNS before and after

This is the step people regret skipping. Before you move anything, screenshot or export your existing DNS records: your A record, your MX records for email, any TXT records for verification and any CNAMEs. If the new provider does not replicate them, your email can stop arriving with no obvious explanation.

Before you transfer, run these checks

A short pause here saves a long afternoon later:

• Your contact email: is the address registered against the domain one you can still access? If it points at an old employee’s inbox, fix that first.
• Registrant details: are the name and address correct? Transfers are smoother when Nominet’s record matches reality.
• Expiry date: is the domain about to expire? Moving a domain in its final week is unnecessarily exciting.
• Existing DNS: have you recorded every record before the move?
• Who actually owns it: if a former developer is listed as registrant rather than your company, sort that out before transferring anything.

Common mistakes we see with .uk transfers

The most frequent one is assuming the tag change moves the website too. It does not. The tag moves administrative control; your site and email keep pointing wherever DNS tells them to, right up until someone changes those records.

The second is losing access to the registrant email address, which turns a five-minute job into a recovery process involving identity checks. The third is transferring during a rebuild, so that when something breaks nobody can tell whether the culprit is the new site, the new host or the domain move; change one thing at a time.

And then there is the quiet one: letting an agency register your domain in their own name as a convenience. It feels helpful right up to the day you want to leave. Own your own domain, always.

Where domain management is heading

Nominet has steadily made .uk domain administration more self-service, and most registrars now expose tag changes directly in the customer control panel rather than requiring a support ticket. Expect that trend to continue, alongside tighter verification of registrant identity and more prompting around two-factor authentication on registrar accounts.

Domain security is also getting more attention generally, partly because a hijacked domain is one of the most damaging things that can happen to a small business. Registrar locks, careful contact details and a real person who knows where the login lives all matter more than they used to.

How long does an IPS tag change take?

The tag change itself is usually near-instant once your current provider actions it, and it typically shows on Nominet’s records within minutes. The waiting is nearly always on the human side: how quickly your old provider processes the request, and how quickly the new one accepts. A day or two end to end is normal.

Will my website go down when I change the IPS tag?

Not from the tag change alone. Downtime happens when DNS or hosting changes at the same time and something is not replicated correctly. If you move the domain and the hosting together, plan the DNS carefully and expect a short propagation window.

Can I change my IPS tag if my domain has expired?

Usually not while it is expired. Renew it first, then transfer. Nominet has a grace period after expiry, but a domain in that state is not in a healthy position to be moved, and leaving it there risks losing it altogether.

Do I need an IPS tag for a .com domain?

No. IPS tags are specific to .uk domains managed by Nominet. A .com, .net or .org uses an authorisation code, sometimes called an EPP code or auth code, which you request from your current registrar and hand to the new one.

What if my old provider will not release the domain?

Ask formally and in writing first, because it is often just a slow support queue. If a provider genuinely refuses to release a domain you legitimately own, Nominet has a dispute process and you can contact them directly as the registry. You are not stuck; it may simply take longer than it should.

Your .uk transfer checklist

• Confirm ownership: your business, not a developer, is listed as registrant.
• Check the contact email: it must be an inbox you can open today.
• Record your DNS: A, MX, TXT and CNAME records saved somewhere safe.
• Get the new tag: exact spelling, correct capitals.
• Renew if needed: do not transfer a domain that is nearly expired.
• Request the change: through your current provider’s control panel or support.
• Accept at the other end: confirm the new registrar has taken it on.
• Verify: check WHOIS shows the new tag, and test that your site and email still work.
• Secure the account: turn on two-factor authentication with the new provider.

Choosing where to keep your domain

Since a transfer is a good moment to think about where the domain should actually live, here is how the main options compare for a small business:

• Keep it with your web host: convenient, because domain, hosting and email sit in one control panel and one bill. The downside is that changing host later means untangling all three at once.
• Use a dedicated domain registrar: keeping domains separate from hosting is what we usually suggest. If you ever fall out with a host, your domain is untouched and you simply repoint it. Slightly more admin, considerably more control.
• Leave it with your agency: easiest in the short term and genuinely fine with an agency you trust, provided your company is the registrant. It becomes a problem only when ownership is fuzzy.
• Register through a reseller: often cheap and perfectly workable, though support can be thinner and tag changes occasionally slower, because the reseller sits between you and the registry.

Whichever you choose, the rule is the same: you should be able to log in yourself, today, without asking anybody’s permission.

Why this small piece of admin is worth understanding

A domain is the one asset in your digital setup that is genuinely irreplaceable. You can rebuild a website, move a mailbox and change an agency; you cannot easily recover a domain that somebody else controls, and every piece of printed marketing you own points at it.

Understanding the IPS tag means you can move providers when you want to, rather than when someone else lets you. That is a small amount of knowledge buying a useful amount of freedom.
