Registered Office Address Rules: What Do I Need to Know?

A registered office address is a legal requirement for every UK limited company and LLP. Since 4 March 2024, following the Economic Crime and Corporate Transparency Act 2023, the rules around what counts as a valid one have tightened considerably. Here's exactly what's required now.

Key Takeaways

• A registered office address must be a physical location, not a P.O. Box, and any change to it must stay within your company's original jurisdiction (England and Wales, Scotland, or Northern Ireland).
• Your registered office is publicly visible, so using a residential address can raise privacy concerns.
• Your registered office must be able to receive and acknowledge post, with someone available to confirm delivery.
• Since March 2024, a registered email address is also mandatory for every company, and it must be actively monitored.
• Non-compliant addresses can be replaced with a Companies House default address, and persistent non-compliance can lead to the company being struck off.

What Are the Legal Requirements for a Registered Office Address?

Does My Registered Office Have to Be in the Same UK Country as My Company?

Yes. Your registered office must be in the same jurisdiction as your company's registration — England and Wales, Scotland, or Northern Ireland. A company registered in Scotland can't use a registered office based in England, and vice versa.

Can I Use a P.O. Box as My Registered Office Address?

No. Before March 2024, a P.O. Box was permitted, but that's no longer the case. If your company still has a P.O. Box listed as its registered office, you risk penalties for non-compliance and should update it to a physical address as soon as possible.

Can I Change My Registered Office to a Different Part of the UK?

No, not without re-registering the company. Any change to your registered office must remain in the same jurisdiction as your company was originally registered in. Changing address within that jurisdiction is straightforward and filed using the AD01 form through Companies House WebFiling, usually processed within 24 hours.

Is My Registered Office Address Public?

Yes. Companies House lists your registered office on the public register, alongside your company name and other core details. Anyone can look this up for free, which is why using a home address here can raise privacy concerns.

Can I Use My Home Address as My Registered Office?

Yes, this is allowed, though it comes with trade-offs. If you rent your property, you may need your landlord's permission, since many tenancy agreements restrict commercial use of the address. Using your home address also makes it publicly visible, alongside your director details.

Does My Registered Office Need to Be Able to Receive Post?

Yes. Since the Economic Crime and Corporate Transparency Act, your registered office must have someone available to sign for and acknowledge receipt of statutory mail. An address that can't do this is considered non-compliant, regardless of whether it's a physical location.

What Happens if My Registered Office Is Non-Compliant?

If Companies House deems your registered office "inappropriate," you can face several consequences: legal non-compliance, missed correspondence, reputational damage, and ultimately the risk of being struck off the register. None of these are proportionate to ignore.

If your address is found non-compliant, Companies House can replace it with a default address — one of three default addresses covering England and Wales, Scotland, and Northern Ireland. This signals to anyone viewing your company that it's currently non-compliant. You then have 28 days to provide a valid address or evidence that your current one is fit for purpose, filed via a paper AD01 form. Even once resolved, the default address remains visible in your filing history as a historic record.

Can a Company Formation Agent Provide My Registered Office Address?

Yes. A formation agent can provide a registered office address that already meets every current requirement, so you don't need to check compliance yourself. This also keeps your personal address off the public register entirely.

Our registered office address service includes a compliant London address, secure mail handling, and use of the same address as your director's service address at no extra cost. If you'd rather understand your options first, our guide on using your home address as your registered office covers the privacy trade-offs in more depth.

Do I Need a Registered Email Address Too?

Yes. Since 4 March 2024, every UK company must also provide a registered email address, separate from your registered office. Companies House uses it to send reminders, queries, and other official communications, so it needs to be a genuinely monitored inbox.

New companies provide this at registration. Existing companies must add one the next time they file a confirmation statement. Our guide to PSCs and the Confirmation Statement covers what else has changed with that filing recently.
