- Every limited company and LLP must maintain an appropriate registered office address for receiving official company documents.
- The address must identify a physical location in the correct UK jurisdiction. You cannot use a Royal Mail PO Box or equivalent mailbox service as the registered office.
- The registered office appears on the public register, so using a home address has privacy implications.
- Companies must also maintain a registered email address, which Companies House keeps off the public register.
What is a Registered Office Address?
A registered office address is the company’s official public address. Limited companies and LLPs must provide one to Companies House and keep it up to date throughout the life of the organisation.
Official notices, statutory correspondence and legal documents addressed to the company can be delivered there. The company does not have to carry out its day-to-day trading activities from its registered office.
Companies House Registered Office Address Rules (2026)
The Companies Act 2006, as amended by the Economic Crime and Corporate Transparency Act 2023, requires every company to maintain an appropriate registered office address at all times. The address must meet the following Companies House requirements.
1. It Must Be in the Same UK Jurisdiction
The registered office must remain in the part of the UK where the company was incorporated:
- England and Wales
- Wales, for a company registered specifically as a Welsh company
- Scotland
- Northern Ireland
A company registered in England and Wales can use an address in either England or Wales. A Welsh company must use an address in Wales, while companies incorporated in Scotland or Northern Ireland must keep their registered offices in those jurisdictions.
2. It Must Be a Physical Address, Not a PO Box
The registered office must designate a physical address in the UK to which company documents can be delivered. A Royal Mail PO Box or an equivalent mailbox service cannot be used as the registered office address.
You can use the physical address of an accountant, solicitor, formation agent or other service provider if you have permission and the address meets all the appropriate address requirements.
Limited companies must also show their registered office address on business letters, order forms and websites, together with their company number and place of registration.
3. Documents Must Reach Someone Acting for the Company
A registered office is appropriate only if:
- documents delivered there would ordinarily come to the attention of someone acting for the company
- the sender can obtain an acknowledgement that the documents were delivered
This does not require a director to remain physically present at the address throughout the day. However, the company must have reliable arrangements for receiving, recording and passing on its statutory mail.
If Companies House decides that an address is inappropriate, it can replace it with a default Companies House address. The company then has 28 days to provide an appropriate address and evidence that it is entitled to use it. Companies House can begin strike-off action if the company does not comply.
You Now Also Need a Registered Email Address
Every company must maintain an appropriate registered email address where messages from Companies House are expected to reach someone acting for the company. New companies provide the email address during incorporation. An existing company that has not already provided one must do so when filing its next confirmation statement.
The registered email address:
- is used by Companies House to communicate about the company
- is not displayed on the public register
- can be used for more than one company
- must be monitored and kept up to date
A company that has already provided its email address can change it through the Companies House registered email address service.
How to Change Your Registered Office Address
You can change your registered office at any time, provided the new address is appropriate and remains in the same part of the UK where the company was incorporated.
To change it:
- Choose an appropriate replacement address and obtain permission to use it.
- File the change through the Companies House online filing service or submit form AD01.
- Notify Companies House within 14 days of the change.
- Continue monitoring the existing address until Companies House registers the filing.
The change does not legally take effect until it has been registered. Companies House will notify HMRC of the new registered office address.
Keeping Your Home Address Private
Your registered office address appears on the public Companies House register and can also be found through search engines and third-party company-information services. You can use your home address, but you should use a different address if you do not want your residential details made public.
An alternative address can be provided by an accountant, solicitor, formation agent or registered office address service. You must have permission to use it, and it must meet the physical-address, jurisdiction and appropriate-address requirements.
If your home address is already on the register:
- Change the registered office first if the company is active.
- Check the company’s filing history to identify the documents containing the address.
- Apply to Companies House using form SR01 to remove the address from eligible documents.
The application costs £34 for each document. If the company has been dissolved, you must wait six months before applying to remove an address previously used as its registered office. Companies House may hide only part of a former address in some circumstances, and removal from its register cannot guarantee that copies already collected by third-party websites will disappear.
This removal process is separate from applying to protect a director’s private usual residential address from disclosure to credit reference agencies. That additional protection is available only where the statutory risk conditions are met.
Registered Office vs Director Service Address
A registered office belongs to the company, while a director service address belongs to an individual director. Both appear on the public register, but they receive different statutory correspondence.
| Factor | Registered office address | Director service address |
|---|---|---|
| Belongs to | The company | The individual director |
| Receives | Statutory mail addressed to the company | Correspondence about the director’s company role |
| Public register | Yes | Yes |
| Location rule | Physical UK address in the company’s jurisdiction | Does not have to match the company’s UK jurisdiction |
| Home address allowed | Yes, but it becomes public | Yes, but it becomes public |
| How to change it | Change the company address with Companies House | File a change to the director’s details |
A director must also provide their usual residential address to Companies House. This is separate from the service address and is normally kept off the public register.
Frequently Asked Questions About Registered Office Addresses
What addresses do you need when forming a company?
Every UK company needs a registered office address, a registered email address and a service address for each director. Directors must also provide their usual residential address, which is normally kept off the public register. A SAIL address is optional.
Why use a registered office service provider?
A registered office service can help keep your home address off the public register while ensuring statutory company mail is received at an appropriate address. Directors remain legally responsible for making sure official correspondence is monitored and acted upon promptly.
How do I replace a PO Box registered office address?
Choose an appropriate physical address in the correct UK jurisdiction, then notify Companies House online or by submitting form AD01. The new registered office takes effect once Companies House registers the change, so continue monitoring your existing address until then.
Can I register my company at a virtual business address in London?
Yes, provided the address is a physical location that meets the Companies House appropriate address requirements and is in the correct UK jurisdiction. Many companies use registered office service providers instead of trading from the registered office itself.
Can a virtual office be used as a registered office or director service address?
Only if the provider offers a service specifically designed for statutory company mail. A general virtual office is not automatically suitable, so always check that it meets the Companies House requirements before using it as a registered office or director service address.
Can I use a virtual address to register a limited company (e.g. Dentistry business) at Company house in the UK?
Yes, you can. A virtual address can be used to register a limited company at Companies House, provided the service package includes more than just mail handling. Alternatively, you can opt for a registered office address service specifically for company formation purposes.
Our registered office address service meets all legal requirements, and your business does not need to operate from this address. It ensures compliance while providing a professional presence for your company without the need for a physical office space.

For now, can I still use the SAIL address to store the company registers offline instead of enabling the Companies House to publicise all the private information on their website?
Hi Doraemon,
Yes, you can use a SAIL address to store your company registers offline, which helps maintain privacy by preventing sensitive information from being publicly accessible on the Companies House website.
All the best!
Can you still use a PO Box address if you also provide the full address of the physical building, including post code.
Hi Clive.
Unfortunately, this is no longer legally permissible. You are now required to provide a physical address, which can be either a residential or commercial building.
Are there any regulations about using a private house as registered office
You can use your private house as a registered office without any regulatory issues. However, keep in mind that the registered office address is publicly available on the Companies House register. If privacy is a priority for you, consider our professional registered office service. This ensures your personal address stays private while giving your business a prestigious London address.
