Every UK limited company needs a registered office address, but that address does not have to be where you actually work, and since March 2024 it cannot be a bare PO Box either. This guide explains the legal requirements, what a virtual office actually provides, and how to choose the right address setup for your company.
Quick Answer
A registered office address is the official address every UK limited company must hold with Companies House, where statutory mail is sent. It must be a real physical UK address, not a PO Box, in the same jurisdiction as your company’s incorporation. A virtual office is a service that provides a compliant physical address, along with mail handling, and can legally serve as your registered office, director’s service address, or trading address.
What Is a Registered Office Address?
Your registered office is the official address recorded on the public Companies House register. HMRC, Companies House, and the courts send statutory correspondence here, and it is visible to anyone who searches your company. Under the Companies Act 2006, as updated by the Economic Crime and Corporate Transparency Act 2023, your registered office must meet what Companies House calls the “appropriate address” test: a real physical location where a document delivered there would reasonably be expected to reach someone acting for the company, and where delivery can be acknowledged.
The Three Address Types Explained
| Address Type | What It’s For | Publicly Visible? |
|---|---|---|
| Registered office | Official Companies House address for statutory mail | Yes |
| Director’s service address | Official address for each individual director, separate from their home address | Yes |
| Trading address | Where the business actually operates or receives general post | Not necessarily |
A single virtual office can often cover all three, which is why many home-based directors use one from day one rather than putting their personal address on the public register.
Can You Use a PO Box as a Registered Office?
No. Since March 2024, the Economic Crime and Corporate Transparency Act 2023 has banned the use of a PO Box alone as a registered office address. A genuine street address is now required, one where mail can actually be received and acknowledged by a real person, not simply collected from a box.
What Is a Virtual Office Address?
A virtual office is a service that provides a genuine street address, typically at a staffed building, along with mail handling such as scanning or forwarding. It is legal to use as a registered office, director’s service address, or trading address, provided the provider genuinely receives and acknowledges post rather than simply renting out a nameplate. If Companies House determines an address is not “appropriate” under the current rules, it can take action against the company, so the quality of the provider genuinely matters.
Using Your Home Address: What to Consider
It remains legal to use your home address as your registered office, but two consequences follow. First, your home address becomes permanently visible on the public register, even after you later change it, since historical filings are not erased. Second, some residential tenancy agreements and mortgage terms restrict using the property for business purposes, so it is worth checking before you register. If privacy matters to you, or you rent your home, a virtual office is generally the safer default from the point you first register your company with Companies House.
Jurisdiction Matters
Your registered office must sit in the same UK jurisdiction as your company’s incorporation. A company incorporated in England and Wales needs a registered office in England or Wales; a Scottish company needs a Scottish address; a Northern Ireland company must maintain its registered office within Northern Ireland. Moving your registered office to a different jurisdiction generally is not straightforward and can affect which courts have authority over your company.
Does HMRC Also Use Your Registered Office?
Yes. HMRC writes to whatever address you provide for Corporation Tax, VAT, and PAYE correspondence, which is often, though not always, the same as your registered office. A virtual office with reliable mail handling reduces the risk of missing an HMRC deadline, particularly for time-sensitive notices relating to your Corporation Tax or VAT position.
What Happens If Your Registered Office Is Not “Appropriate”?
If Companies House cannot confirm your registered office is appropriate, or mail sent there is consistently unacknowledged, it can change your registered office to a default Companies House address, and ultimately move towards striking your company off the register for non-compliance. This is a genuine risk for companies using a cheap, unstaffed forwarding address rather than a properly managed virtual office service.
Choosing a Virtual Office Provider
- Confirm the address is a genuinely staffed location, not just a mailbox with a prestigious postcode
- Check whether mail is scanned, forwarded, or both, and how quickly
- Confirm the provider covers the correct UK jurisdiction for your company
- Check whether the service also covers your director’s service address, since this is often sold separately
- Compare pricing, since basic registered-office-only services cost less than full virtual office packages with call handling and meeting rooms
Frequently Asked Questions
Can a virtual office be used as a registered office in the UK?
Yes, provided it is a genuine physical address where post is reliably received and acknowledged, in the correct UK jurisdiction for your company.
Can I use a PO Box as my registered office address?
No. A PO Box alone has not been accepted as a registered office address since March 2024.
Does my home address stay private if I use a virtual office?
Yes. Using a virtual office as your registered office and director’s service address keeps your residential address off the public Companies House register.
Does my registered office have to match where I actually work?
No. Your registered office is simply the official address for statutory mail. Your trading address, where you actually operate, can be different.
Can a Northern Ireland company use an England-based registered office?
No. A company incorporated in Northern Ireland must maintain its registered office within Northern Ireland.
