A registered office address is the official legal address of a UK limited company, recorded at Companies House and shown on the public register. It’s where statutory mail from Companies House, HMRC, and the courts is legally sent, and it must be a real, physical address in the same UK jurisdiction where the company is incorporated. It does not have to be where you actually work.
That last point trips up a lot of first-time founders. You can run your business from a kitchen table in Manchester and still have your registered office listed as a serviced address in London as long as that address meets Companies House’s rules. Here’s what those rules actually require, why so many directors end up paying for a dedicated address service, and what changes if you’re forming a UK company from outside the UK.
The Legal Rules: What Counts as an “Appropriate Address”
Since March 2024, following the Economic Crime and Corporate Transparency Act 2023, Companies House has tightened the definition of a valid registered office. It’s no longer enough to just list any address it has to qualify as an “appropriate address.” In practice, that means two things:
- A document delivered to the address by hand or post would reasonably be expected to reach someone acting on behalf of the company.
- Delivery to that address can be recorded with an acknowledgement of delivery (essentially, someone has to be able to sign for or confirm receipt of mail there).
A few practical consequences follow from this:
- PO Boxes are no longer allowed. Because nobody can sign for or acknowledge delivery at a PO Box, it fails the second test outright. If your company still has one listed, you’re required to change it.
- The address must sit in the correct jurisdiction. A company registered in England and Wales needs its registered office in England or Wales; Scotland-registered companies need a Scottish address; Northern Ireland companies need one there. You can’t use an address in a different UK nation, and you can’t use an address in an entirely different country. This applies even if you use a virtual office provider their address has to physically sit in the right jurisdiction.
- Non-compliant addresses can trigger enforcement. Companies House can change a company’s address to a default one and give the company a limited window commonly cited as around 14 to 28 days to provide a valid replacement before starting strike-off proceedings. Persistent non-compliance can also carry fines.
- A registered email address is now mandatory too. Alongside the physical address reforms, companies must give Companies House an email address where messages are likely to reach someone acting for the company. This email isn’t published on the public register it’s for Companies House’s internal use only.
Whatever address you choose, it needs to be one you can genuinely keep monitored, since missed statutory mail is a compliance risk in its own right, not just an inconvenience.
Why Your Home Address Becomes a Public Record And the Risks
This is the part that catches most sole director founders off guard: if you list your home address as the registered office, it becomes permanently visible on the public register at Companies House. Anyone a customer, a competitor, a stranger can look up your company and see your home address.
That has some real, practical downsides:
- Loss of personal privacy. Your home address is searchable by anyone, indefinitely, for as long as the company exists (and it often stays visible in historical filings after the company closes).
- Unwanted posts and marketing. Registered offices tend to attract a steady stream of junk mail, cold sales letters, and speculative offers addressed to “The Director.”
- Personal safety concerns, particularly for sole traders, freelancers, or anyone running a business where a client or member of the public could have reason to turn up in person.
- A less professional impression. A residential address on your incorporation documents and website footer can be read as less established than a business address, which matters more than founders expect when dealing with clients, suppliers, or investors doing due diligence.
There is a related but separate address on the public record worth knowing about: the director’s service address. This is a distinct field from the registered office, and it’s specifically meant to let directors avoid publishing their home address even if the company’s registered office is elsewhere. If you haven’t set a separate service address, your home address may end up exposed twice: once as the registered office, and again as your personal service address so it’s worth checking both fields on your Companies House filing.
Registered Office Address Services: What They Are and What They Cost
A registered office address service (sometimes marketed as a “virtual office” or “company address service”) is a professional address
usually provided by a formation agent, accountant, or dedicated mail-handling company that you use as your official registered office instead of your home or a rented office you don’t want listed publicly.
Typically, the service includes:
- Mail scanning and forwarding, so post is scanned and emailed to you (or physically forwarded) rather than piling up unopened
- Sometimes a separate director’s service address, so your home address doesn’t appear anywhere on the public record
- Ongoing compliance monitoring, so if Companies House correspondence arrives, it’s flagged and dealt with promptly rather than missed
Cost: Most UK registered office address services run roughly £30–£100 per year, depending on the provider, the location (central London addresses tend to sit at the higher end), and whether mail forwarding is included or charged separately. It’s a modest annual cost relative to the privacy and professionalism it buys back.
For most small companies, a registered office service pays for itself the first time it prevents an important HMRC or Companies House letter from getting buried under junk mail or the first time it saves you from having your home address permanently searchable online.
Non-Resident Requirements: Forming a UK Company From Abroad
If you don’t live in the UK, a registered office address service isn’t just a privacy nice-to-have it’s usually a practical necessity. Companies House requires every UK company, regardless of where its directors or shareholders live, to have a registered office that is a physical UK address in the correct jurisdiction. There’s no exemption for non-resident directors.
That means if you’re incorporating a UK company from overseas, you’ll need one of the following:
- A UK-based friend, relative, or business partner willing to let you use their address (with their consent, since it becomes publicly visible)
- A UK office or premises you already lease
- A registered office address service, which is by far the most common route for non-resident founders, since it requires no UK premises of your own and comes with mail handling built in
Because the address must also be one where the post can genuinely be acknowledged and reach someone acting for the company, an ad hoc solution like a UK contact who might move house carries more compliance risk than a dedicated service built for exactly this purpose.
Frequently Asked Questions
Can I use a PO Box as my registered office address? No. Since March 2024, PO Boxes no longer meet the “appropriate address” definition, because nobody can sign for or acknowledge delivery there. If your company currently uses one, you need to change it.
Can I change my registered office address later? Yes. You can update it at any time by filing form AD01 with Companies House, which is free and can usually be done online within minutes. You must notify Companies House within 14 days of the change, and the update is only official once Companies House registers it on the public record.
Is my home address made public if I use it as my registered office? Yes. Whatever address is listed as your registered office appears on the public register and is visible to anyone who looks up your company, indefinitely for as long as the company exists. This is exactly why many directors, especially sole traders working from home, choose a registered office address service instead.
