What is a registered office address? UK rules explained

A registered office address is your company's official address on the public register at Companies House. It's where Companies House and HMRC send statutory post, and it's shown publicly for anyone to see. Every UK limited company must have one. Here's exactly what that means, and how to choose one.

What is a registered office address?

Your registered office is the official address Companies House holds for your company: the legal address for your business on the public record. It's where the government sends official post: letters from Companies House and tax correspondence from HMRC. It doesn't have to be where you actually work, and you don't have to own it. It just has to be a real address where official mail will reach you.

That last point trips people up. You don't need an office. You don't need staff. A consultant working from a laptop, a freelancer, an online shop: all of them still need a registered office on the record. It's the address the state writes to, not a description of where the work happens. A coffee-shop founder and a 50-person firm follow exactly the same rule here.

Is a registered office address a legal requirement?

Yes. Every company registered in the UK must have a registered office address at all times. You provide it when you incorporate, and it stays on the register for the life of the company. According to gov.uk, the address must be a physical location in the UK; it can't just be a name with no place attached to it.

"At all times" is the key phrase. The requirement doesn't pause if you move, change banks, or stop trading for a while. If you let the address lapse, or post starts bouncing, the company falls out of step with its legal duties, and that's a problem you'll want to fix quickly rather than ignore.

Does a dormant company still need a registered office?

Yes. A registered office is required for as long as the company exists on the register, whether it's trading or dormant. Even a company that's filed nothing but dormant accounts still receives statutory post from Companies House and HMRC, so the address has to stay valid and appropriate (gov.uk).

This catches founders who set up a company "to hold the name" and then forget about it. A dormant shelf company is still a live legal entity. Filing reminders, confirmation-statement notices and the odd HMRC letter all land at the registered office. If nobody's reading them, deadlines slip, and the company can drift towards being struck off.

Does it have to be in the same part of the UK as my company?

Yes. Your registered office must be in the same UK jurisdiction where your company is incorporated. A company registered in England & Wales must keep its registered office in England & Wales; a Scottish company must use a Scottish address; and a Northern Irish company must use one in Northern Ireland (gov.uk). You can't use an overseas address as your registered office, even if you run the business from abroad.

So picture a founder in Edinburgh who incorporates a company in Scotland. They can't later switch the registered office to a London address: that would cross jurisdictions. And someone running an England & Wales company from Manchester can't use a friend's flat in Glasgow. The jurisdiction is set when you incorporate, and the registered office has to stay inside it.

This matters for non-UK residents too. Living overseas doesn't stop you owning a UK company, but the registered office still has to be a real UK address in the right jurisdiction. That's why founders setting up from abroad usually pair the company with a UK registered office service rather than trying to use an address back home.

What is the "appropriate address" rule?

Since 4 March 2024, your registered office must be an "appropriate address": somewhere a document would be expected to come to the attention of a person, and where delivery can be acknowledged. The change came in under the Economic Crime and Corporate Transparency Act. In practice it means a PO box on its own is no longer allowed as a registered office (gov.uk).

Two simple tests sit behind the rule. First, would a posted document realistically reach a person there? Second, could someone acknowledge that it arrived? A bare PO box fails on the second test (there's no one to confirm delivery), which is why a box on its own no longer qualifies.

What happens if Companies House finds an address inappropriate?

If Companies House decides an address isn't appropriate, it can change it to a default address, and the company then has to provide an appropriate address with evidence or risk being struck off (gov.uk). In plain terms: getting this wrong isn't a polite warning, it can put the company itself at risk.

That's the practical case for a genuine, staffed address over a box or an unattended unit. At MVOS, post sent to our Belgravia building is received and digitally scanned to your portal, so delivery is genuinely acknowledged and nothing sits unopened: exactly the standard the appropriate-address rule is built around.

Is a registered office address public?

Yes, and this catches a lot of first-time founders out. Your registered office is published on the Companies House register, which anyone can search for free on the official Find and update company information service. So whatever address you give becomes public information attached to your name and company.

Think about who can see it: customers, suppliers, competitors, marketers building mailing lists, and anyone who simply types your company name into the register. Once it's published, it's published. That's a calm, deliberate decision to make before you incorporate, not something to discover after the letters start arriving.

What's the difference between a registered office and a service address?

They're two different things, and a company has both:

Crucially, a director's residential address is protected and not shown publicly: only the service address is (gov.uk). A registered office service can act as both your company's registered office and your service address. If you want the full breakdown, see registered office vs service address vs business address.

Can I use my home address as my registered office?

You can: there's no rule against it. But because the registered office is public, your home address becomes searchable by customers, suppliers, and anyone else. That's the single biggest reason founders choose a separate registered office service: it keeps their home address off the public register while still meeting Companies House requirements.

There's a knock-on effect worth knowing. Once your home is on the register, it can be hard to fully claw back, because copies of old data spread across third-party sites. Many founders weigh that up and decide the cleaner route is to keep home and company separate from day one. We walk through the trade-offs in can I use my home address as a registered office.

How do I change my registered office address?

You can change your registered office at any time through Companies House, online or by filing form AD01, and it's free to do (gov.uk). The new address still has to meet all the rules above: an appropriate address in the same UK jurisdiction. The change takes effect once Companies House registers it.

A common moment for this is moving home, or finally getting a home address off the register after using it at the start. The form is short and the change is free. The only firm requirement is that the new address clears the same bar: appropriate, and in the right jurisdiction. There's a full walkthrough in how to change a registered office address.

Choosing the right registered office is one of the first real decisions you make when you start a company. If you'd rather not put your home address on the public record, a registered office service gives your company a professional London address with post received and digitally scanned to you, useful whether you're in the UK or forming a company as a non-UK resident.
