Every registered office address for a limited company UK-wide has to meet a specific legal standard, and the rules tightened in March 2024. Getting this wrong is not a paperwork technicality; it can affect whether your company can be struck off the register. Here is what the rules actually require, in plain terms.
The appropriate address requirement
Since March 2024, every registered office address for a limited company UK companies use must be an "appropriate address". This means:
- A person acting on behalf of the company can reasonably be expected to see documents delivered there
- Any documents delivered can be recorded and acknowledged as received
This rule exists because Companies House found too many companies using addresses where post was never checked, sometimes deliberately, to avoid statutory correspondence. An appropriate address closes that gap.
No PO Box on its own
A PO Box cannot be used as a registered office on its own, because it fails the "acknowledged receipt" test: there is no one to confirm documents have arrived. A registered office must be a genuine physical location, staffed or monitored in a way that lets post be received and dealt with.
This is one reason a proper registered office service, rather than a basic mail-forwarding box, matters. Keystone's registered office at 167-169 Great Portland Street, London W1W 5PF is £50 a month and includes receipt and forwarding of official post, which satisfies the appropriate address standard for a registered office address for a limited company UK regulators now expect.
Where documents must be delivered and acknowledged
The core test is simple: could a document dropped at this address realistically be seen and acted on by someone connected to the company? If the answer is no, whether because the address is empty, unmonitored, or simply a forwarding box with no oversight, it does not qualify. This applies regardless of company size; a one-person company run by a non-resident director is held to the same standard as a large firm.
For directors based abroad, this is exactly the gap a dedicated registered office service is designed to close. Post that would otherwise sit unopened is received, checked, and forwarded promptly, which matters given how time-sensitive some statutory deadlines are.
What happens if mail goes ignored
Ignoring official correspondence sent to a registered office carries real consequences. Confirmation statements, for example, are due within 14 days after each 12-month review period ends, and the £50 fee for a digital filing covers unlimited statements within that period. Missing the deadline because a reminder was never seen is a criminal offence for directors and can lead to the company being struck off the register.
HMRC correspondence carries similar risk. Notices about Corporation Tax, currently 25% on profits over £250,000, 19% under £50,000 with marginal relief between, are sent to the registered office, and missed replies can escalate quickly. A registered office service that reliably forwards post, backed by Company Secretarial Support that tracks filing deadlines, removes this risk almost entirely.
Changing your registered office address
If your registered office needs to change, whether you are switching providers or moving location, it is done by filing form AD01 with Companies House. The new address must itself meet the appropriate address requirement from day one. Our Director & Shareholder Changes service can handle this filing directly, so the change is registered correctly without gaps in mail coverage.
This is also worth planning for at the point of UK company incorporation, where a registered office address for a limited company UK entity is set for the first time and, ideally, chosen so it will not need to change again shortly afterwards.
Common questions
Can I use my home address as my registered office?
Yes, provided it meets the appropriate address test, though many directors, especially those living abroad, prefer to keep their home address off the public register.
What counts as an appropriate address?
Somewhere a person acting for the company can be expected to see delivered documents and where receipt can be acknowledged. A monitored, staffed address qualifies; an unmonitored PO Box does not.
Is identity verification linked to the registered office rules?
Not directly, though both are part of the same wider transparency changes under the Economic Crime and Corporate Transparency Act 2023. From 18 November 2025, new directors must verify their identity before incorporation, with existing directors and PSCs given a 12-month transition.
How do I change my registered office address?
By filing form AD01 with Companies House, which our Director & Shareholder Changes service can manage for you.
What happens if Companies House decides my address is not appropriate?
They can require you to change it, and in some cases can strike the company off the register if statutory correspondence consistently fails to reach it.
