Registered office and address privacy: what becomes public?

Three addresses that serve different purposes

The registered office is the company’s official address for formal correspondence. A director’s service address is where official correspondence for that individual can be delivered. The usual residential address is the director’s actual home address, supplied separately to Companies House.

These can sometimes be the same place, but they are not interchangeable fields. Entering your home as the registered office or service address normally makes it public. Using a paid address for public correspondence does not remove the need to supply genuine residential details where required.

What makes an address appropriate?

The registered office must be in the jurisdiction of incorporation: for example, a company registered in Scotland needs a Scottish registered office. Companies House treats England and Wales as a registration jurisdiction; check any specific Welsh registration requirements. A standalone PO Box is not acceptable.

An address is appropriate if documents sent there would come to the attention of someone acting for the company and delivery can be acknowledged. It is not enough to rent an address that you cannot reliably access. You must also give Companies House an appropriate registered email address; that email address is not displayed publicly.

Check an address service before paying

A low first-year price may hide different scope, renewal fees or mail-handling costs. Ask what the service includes and whether it accepts official correspondence for your company and its directors.

• Correct registration jurisdiction and permission to use the address.
• Whether registered office and director service address are separate products.
• Which letters are scanned, forwarded or excluded.
• Mail delivery speed, charges and escalation for urgent notices.
• Renewal price, automatic billing and cancellation notice.
• How official mail is handled when the service ends.

Changing an address does not automatically remove history

Updating your current registered office stops future correspondence going to the previous address, but old documents may still show earlier information. Do not assume that switching to a paid address removes your home from historical filings.

Companies House has processes to apply for suppression of certain personal information. Eligibility, evidence and fees depend on the information and application. Check current guidance instead of relying on a promise that an address service can make all records private.

Treat official mail as an operational responsibility

Set up a regular process to review mail and the registered email inbox. Important notices may relate to filings, tax, legal proceedings or verification. Forwarding delays do not necessarily extend statutory deadlines.

If you move or change provider, submit the required changes promptly and separately update HMRC, banks and other organisations where needed. Never assume a Companies House update synchronises every system.

Worth knowing: Privacy is easiest to protect before your first filing. A public contact address must still work reliably.

What to ask an address provider before using its postcode

The registered office must be a physical, appropriate address in the company’s UK jurisdiction. Someone acting for the company should be made aware of deliveries, and delivery should be capable of acknowledgement. A PO Box alone is not enough. A provider’s permission matters; do not use an impressive address copied from another website.

Ask which mail the package accepts: Companies House and HMRC only, all business letters, bank cards, recorded delivery or parcels. Ask how quickly mail is scanned, how forwarding is charged, what happens to originals and whether access continues briefly after cancellation. A low address price can conceal per-item forwarding fees or a limited official-mail-only service.

Check whether director service addresses are included separately from the registered office. Also ask whether the package can support the jurisdiction of incorporation. A London registered office is not suitable for a company registered in Scotland. Keep the provider contract and a named contact for urgent or returned mail.

Privacy is best planned before filing; later changes have limits

Using a service address does not make the company anonymous. Names, appointments, ownership information and other register material may remain public. Your residential address may also appear in a filed document if you accidentally use it in a public field. Review the application’s preview before submission instead of assuming the provider will remove every private detail.

Moving the registered office is a formal register change, not merely updating an email signature. Arrange overlap with the former mail service, notify relevant organisations and check filing confirmation. If you lose permission to use an address, act promptly; Companies House has powers concerning inappropriate addresses.

Historical documents are not automatically rewritten when an address changes. Companies House has specific routes for protecting or removing some personal information, with eligibility and fees that must be checked. If you face a safety risk, consult those official protection services before filing unnecessary personal details.

The Three Address Types in Practice: Legal vs Operational Realities

While the Registered Office, SAIL, and Director's Service Address each appear on the public record, they carry vastly different legal weights and operational implications. The Registered Office is the most critical; it is the company's official address for all legal notices and correspondence from government bodies like Companies House and HMRC. Any document legally served at this address is considered received by the company, regardless of whether it was actually seen. Failure to maintain an effective Registered Office where mail can be promptly received and acted upon can lead to severe penalties, including the company being struck off the register. This address must be a physical location in the correct UK jurisdiction (e.g., England & Wales), not a simple PO Box.

A Single Alternative Inspection Location (SAIL) is an optional, secondary address designed for convenience. It allows a company to keep certain statutory records (like the register of members or directors' service contracts) available for public inspection at a location other than the Registered Office. This can be practical if administrative staff work from a different site. However, its use must be officially notified to Companies House using Form AD02. The Director's Service Address is purely for the individual director, not the company. It's the official address for correspondence sent to them in their capacity as a director. Crucially, using a non-residential service address is the primary mechanism for keeping a director's home address off the public register, a vital privacy protection.

The interplay between these addresses requires careful management. For example, if you list a SAIL address, you are legally obligated to ensure the specified records are physically present and accessible there during business hours. If an inspector calls and the records are not available, the company and its officers are in breach of the Companies Act 2006. Similarly, while a Director’s Service Address protects a home address from public view, the director must still have a reliable system for receiving mail sent there. For most small businesses, using a single, professional address service for both the Registered Office and all directors' service addresses is the most straightforward and secure way to manage these distinct legal obligations efficiently, ensuring all official mail is consolidated and handled correctly.

Worth knowing: The Registered Office is a non-negotiable legal requirement for receiving official notices, whereas a SAIL is an operational choice and a Director's Service Address is a key tool for personal privacy.

Cost-Benefit Analysis: Home Address vs. Professional Address Service

Choosing an address for your company involves balancing the immediate cost against long-term risks and benefits. Using your home address as the Registered Office and for directors is, on the surface, free. However, this approach carries significant non-financial costs. Your private residential address becomes permanently published on the public register, accessible to anyone from marketing agencies and data miners to disgruntled clients or fraudsters. This can lead to unwanted mail, unsolicited visitors, and an erosion of personal and family security. Furthermore, using a residential property for business purposes may violate your mortgage agreement, tenancy lease, or home insurance policy, creating potential legal and financial complications. The perceived saving is often a false economy when these privacy and compliance risks are considered.

A professional address service, such as mail forwarding or a virtual office, introduces a direct annual cost but effectively mitigates the risks of using a home address. For a modest fee, these services provide a compliant, professional city-centre address for the public record, shielding your home from view. This not only enhances your privacy but also boosts your business's credibility and image. The service acts as a buffer, filtering junk mail and ensuring you receive all critical statutory documents from HMRC and Companies House in a timely manner. The annual fee for such a service can be viewed as an insurance premium against privacy breaches, compliance issues with your property agreements, and the operational headache of managing statutory mail at home. All service fees are also a legitimate tax-deductible business expense.

Worth knowing: While a home address has no direct fee, a professional service costing c. £200-£600 annually is a tax-deductible expense that buys crucial privacy, compliance, and professionalism; chart figures are illustrative market estimates.

Common Address Filing Mistakes and Their Official Remedies

Several common mistakes during and after company formation can compromise your privacy and legal standing. A primary error is using a PO Box number as a Registered Office address. The Companies Act 2006 requires a physical address capable of receiving documents, and while a PO Box can be part of the address, it cannot be the address itself. Companies House systems will typically reject such filings, but if one slips through, the company is not compliant. Another frequent issue is letting a professional mail forwarding service subscription lapse. If the provider returns mail to Companies House, it can trigger a process for compulsory strike-off, as the company is deemed to be uncontactable. This can happen surprisingly quickly and puts the business and its assets at risk.

A particularly damaging mistake for privacy is initially using a director's home address as their service address, perhaps as a temporary measure, and then failing to change it promptly. Even after filing a change, the original home address remains on the public record as part of the filing history. While the new address becomes the current one, the old one is not automatically erased. However, there is a specific legal remedy for this situation under sections 1088 and 1095 of the Companies Act 2006. You can apply to have a historic home address removed from the register where it was previously used as a service address. This is a crucial, but often overlooked, procedure for restoring privacy after an initial mistake.

1. 1

   First, you must change the director's service address to a new, non-residential address by filing form CH01 (for an individual director) online or by post.

2. 2

   Once the change is registered, you can apply to remove the historic home address using form RP02A ('Application to remove a home address from the register').

3. 3

   This form requires the director's name, the company number, and details of the document(s) where the home address was published.

4. 4

   You do not need to provide a reason or evidence of risk, unlike more advanced protection applications. This procedure is specifically for when a home address was used as the public service address.

5. 5

   There is a statutory fee for this application, payable to Companies House. As of October 2026, you should check the current fee on GOV.UK before applying.

6. 6

   Once approved, Companies House will suppress the home address from the public-facing register, including in historic scanned documents, effectively restoring the director's privacy.

Worth knowing: Letting a mail service lapse can lead to company strike-off, but if you mistakenly used a home address, you can later apply to have it removed from the public record using a specific procedure.

Advanced Privacy: The 'Protection of an Address' Application

For company directors who face a serious, credible risk of violence or intimidation as a result of their company's activities, standard privacy measures may be insufficient. In these exceptional circumstances, Section 243 of the Companies Act 2006 provides a powerful but stringent protection mechanism. This application allows a director to prevent their residential address from being disclosed to credit reference agencies by Companies House. Normally, even if a director uses a professional service address on the public register, their residential address (which must still be provided to Companies House) is shared with these agencies. The Section 243 protection stops this disclosure, adding a significant layer of security.

Qualifying for this protection requires a high burden of proof. It is not available to those simply seeking general privacy. The applicant must provide compelling evidence that they, or someone living with them, are at serious risk. This is not the same as the more routine application to remove a home address that was mistakenly used as a service address (Form RP02A). This is a specific security provision intended for individuals linked to companies that might attract activism, harassment, or criminal attention. The application is made to Companies House using form SR04, and if successful, it means the director's home address is among the most securely held information in the register.

• Eligible applicants include company directors, secretaries, and any person who has provided a residential address to Companies House.
• The application must be supported by evidence demonstrating a 'serious risk of violence or intimidation'.
• Examples of valid evidence include a police incident log or crime reference number, a court order or injunction, or a letter of attestation from a senior police officer or relevant authority.
• The protection, if granted, prevents Companies House from disclosing the individual's residential address to credit reference agencies.
• This is separate from the protection available to Persons with Significant Control (PSCs) under Section 790ZF, which can hide all of a PSC's information from the public register if they are at risk.

Worth knowing: The Section 243 application offers the highest level of address protection for directors facing a serious risk of harm, but it requires substantial evidence and is distinct from standard privacy options.

Address Compliance Triggers: Responding to Time-Critical Statutory Mail

A company's Registered Office is not a mere mailbox; it is the legal destination for statutory documents that can determine the company's fate. Failing to receive, open, and act upon this mail is equivalent to ignoring a court summons. The consequences are severe and automated. For instance, if Companies House sends correspondence (such as a confirmation statement reminder) that is returned by the mail provider, it will assume the company is no longer trading. This triggers the issuance of a 'First Gazette notice for compulsory strike-off', which is published publicly. If the company does not respond within the specified period, it will be dissolved, and its assets, including its bank account, will become property of the Crown ('Bona Vacantia').

Similarly, mail from HMRC must be treated with utmost urgency. A brown envelope containing a 'Notice to Deliver a Company Tax Return' (form CT603) starts a statutory clock. Failure to file the tax return by the deadline results in automatic late filing penalties, which escalate over time, regardless of whether any tax is owed. More seriously, legal documents from courts or other litigants served at the Registered Office demand immediate attention. A High Court or County Court Claim Form, for example, gives a very limited time (typically 14 days) to formally acknowledge the claim. Ignoring it allows the claimant to apply for a 'judgment in default', meaning you automatically lose the case, which can then be enforced against the company's assets.

Worth knowing: Failure to act on mail sent to the Registered Office from Companies House or HMRC can directly lead to automatic fines, default judgments, and the dissolution of your company.

Director ID Verification and Address Privacy Post-November 2025

The Economic Crime and Corporate Transparency Act 2023 introduced a significant change for all UK companies: mandatory identity verification for all new and existing directors and Persons with Significant Control (PSCs). Since 18 November 2025, anyone being appointed to these roles must verify their identity with Companies House through a secure digital process. This involves linking a real-world identity to the company officer, typically by using an app to scan their face and photo identification, such as a passport or driving licence. The primary goal is to increase transparency and trust in the UK's corporate framework, making it much harder to appoint fictitious directors or for individuals to hide their involvement in multiple companies behind false details.

This new process has important implications for address privacy. During verification, Companies House will capture personal data from your identity documents, which almost always includes your residential address. However, it is crucial to understand that this verification data is held privately and securely by Companies House for its own integrity purposes. It is NOT published on the public company register. This change reinforces the importance of the Director's Service Address. While your home address is used to verify who you are, your designated service address is what appears on the public record for correspondence. This system effectively decouples your secure, private identity from your public-facing corporate role, allowing the register to be more trustworthy without sacrificing the personal privacy of legitimate directors.

• The requirement to verify identity applies to all directors, PSCs, and equivalent roles in other registerable entities (e.g., LLPs).
• Verification is primarily done through a digital service using a mobile app, linking biometric data to a photo ID.
• Failure for a director to be verified is a criminal offence, and the company also commits an offence for allowing an unverified director to act.
• The verified status of a director will be visible on the public register, but the underlying evidence (like your home address or passport number) will not be.
• This reform makes the use of a professional Director's Service Address even more important to maintain a clear line between private life and public corporate duties.

Worth knowing: Mandatory ID verification from November 2025 uses your private home address to confirm your identity, but this information is not made public, reinforcing the value of a separate, public service address.
