Using the wrong address when registering a UK company is a mistake that should be corrected promptly, but it does not usually mean you need to close the company and start again. The right solution depends on which address is wrong. A UK company has several different address requirements, and they are not interchangeable. The company's registered office, a director's service address and a director's usual residential address have different purposes and different rules.

If you entered the wrong registered office address during incorporation, you normally need to change it with Companies House using the appropriate registered-office procedure. If the mistake concerns a director's address, the correction may instead involve the director's details. This distinction matters because some addresses are public, some are kept private, and some must satisfy specific legal requirements.

First: Identify Which Address You Entered Incorrectly

Before submitting a correction, determine exactly what went wrong. There are three addresses that commonly cause confusion during UK company formation:

Companies House requires a company to have an appropriate registered office address. A director must also provide a service address and usual residential address. The service address may be the same as the company's registered office, but it does not have to be. So, "I used the wrong address" is not enough to determine the correction process. The first question should be: Was the wrong address entered as the company's registered office, or as a director's address?

If You Entered the Wrong Registered Office Address

This is one of the most common address mistakes during incorporation. The registered office is the official address of the company. It appears on the public Companies House register and is where official documents and correspondence can be sent. A registered office must be:

• A physical address in the UK
• In the same UK jurisdiction as the company
• An appropriate address where company correspondence should come to the attention of someone acting for the company
• An address where delivery can be recorded

A Royal Mail PO Box cannot be used as a registered office address, and similar mailbox-only arrangements do not satisfy the current requirements unless the arrangement also provides an appropriate physical address meeting the legal requirements.

Example

Suppose you incorporated an English company and accidentally entered: 10 Example Street, Manchester when you intended to use: 25 Example Road, Manchester, The company has already been incorporated. You do not need to form another company simply because the registered office is wrong. You should change the registered office with Companies House.

How to Change Your Company's Registered Office

The standard process is to file a change of registered office address using the Companies House online service, commonly associated with form AD01. Companies House says you must tell it within 14 days of the change taking place. The online service requires the company's authentication code. The process is broadly:

1. Obtain a suitable replacement address.
2. Confirm that it meets the registered-office requirements.
3. Make sure it is in the correct UK jurisdiction.
4. Submit the registered-office change through Companies House.
5. Check that Companies House has registered the change.
6. Update your internal records and any relevant suppliers or professional advisers.

An important point is that the new address does not officially become the registered office until Companies House registers the change.

Don't simply start using the new address

If you have submitted an AD01 but Companies House has not yet registered the change, do not assume that the new address has immediately replaced the old one for legal purposes. Keep monitoring the filing until the change appears on the company's Companies House record.

What If I Used My Home Address as the Registered Office?

This deserves special attention. If you used your home address as the company's registered office during incorporation, that address becomes publicly available on the Companies House register. You can change the registered office to another appropriate address, but changing it does not necessarily erase the historical address from the company's record.

Companies House has stated that previous registered office addresses remain on the public register for the lifetime of the company and for 20 years after the company has been dissolved. This is why founders who value privacy should think carefully about the registered office address before incorporation, particularly if they are operating from home.

Can I remove my home address?

There are separate procedures for removing certain personal information from the public register. Companies House guidance says that if a home address was used as the company's registered office, an active company must first change its registered office before applying to remove the home address. However, changing the registered office does not mean every historical reference to the old registered office automatically disappears.

What If the Address Was Not Appropriate?

Sometimes the issue is not that you typed the wrong address. The address itself may not satisfy Companies House requirements. For example, the address could be:

• A PO Box without an appropriate physical address
• An address in the wrong UK jurisdiction
• An address where company correspondence will not reach someone acting for the company
• An address where delivery cannot reasonably be recorded
• An address used without the necessary permission or arrangement

Companies House can query information and has powers to take action where a registered office does not meet the legal requirements. The company must have an appropriate registered office at all times. This is particularly important for founders using virtual-office or address services.

A commercial address is not automatically acceptable simply because it is advertised as a "business address." The actual service must satisfy the Companies House requirements.

What If I Entered the Wrong Director Address?

If the mistake concerns a director rather than the company, the process is different. A director has two relevant addresses:

Service address

The service address is the public correspondence address for the director. It can be:

• The company's registered office
• The director's home
• Another suitable address

The service address appears on the public Companies House register.

Usual residential address

This is the director's actual home address. Companies House requires it to be provided, but it is normally kept on a private register rather than being publicly displayed. These two addresses should not be confused.

How to Correct a Wrong Director's Address

If you entered the wrong director address during incorporation, first establish whether:

1. The original filing contained a mistake; or
2. The director's address genuinely changed after incorporation.

That distinction is important because the filing route can differ. For a subsequent change to an individual director's details, Companies House uses CH01. For example, imagine:

A director lived at 15 High Street when the company was incorporated and correctly supplied that address. Six months later, the director moved to 20 Park Road.

That is a genuine change of address. By contrast:

The director lived at 20 Park Road when the company was incorporated, but 15 High Street was entered by mistake.

That is an error in the original filing. You should not automatically treat the second situation as though the director had simply moved. Companies House provides separate processes for changing director details and replacing documents that contain errors.

When Should You Use CH01?

CH01 is used to notify Companies House of relevant changes to an individual director's details. The current CH01 form covers changes including a director's name and address information. For example, CH01 may be appropriate where a director genuinely changes their service address after incorporation.

It is important to understand that filing CH01 is not necessarily the same as correcting an inaccurate historical filing. If the original incorporation document itself contained an error, you should check whether the Companies House replacement-document process is more appropriate.

What If the Wrong Residential Address Was Entered?

A wrong residential address should also be corrected. The residential address is important because Companies House uses it as part of its records for directors. Although it is not normally displayed publicly, it is still information that the director is required to provide. If you accidentally entered an old home address, another person's address or a completely incorrect address, do not simply leave it because it is not publicly visible.

The correct approach depends on how the error arose and which filing contains it. If the residential address genuinely changed after incorporation, the director's details can be updated using the applicable Companies House process. If the address was incorrect from the beginning, investigate the correction or replacement-filing route instead.

What If I Put My Home Address as the Director's Service Address?

This is different from accidentally entering the wrong address. You may use your residential address as a service address, but doing so generally means that your home address becomes publicly visible as the director's service address.

Companies House specifically states that if a residential address is entered in the service-address section, it appears on the public record. If privacy is important, a director can use a different suitable service address. For example:

Residential address:
Private home address

Service address:
Professional correspondence address

The residential address remains on the private Companies House record, while the service address is the one displayed publicly. For founders running companies from their homes, this distinction is worth understanding before incorporation rather than after personal information has already appeared on the register.

What If I Used an Address Belonging to Someone Else?

If you accidentally used another person's address, take action promptly. This could happen when:

• An old address was copied into the form
• A previous adviser’s address was entered
• A landlord's address was used accidentally
• A virtual-office address was entered without the appropriate arrangement
• A director's old address was selected from an autofill field

If the address is the company's registered office, replace it with an appropriate address. If it is a director's address, determine whether it was entered as the service address or residential address and follow the relevant correction process. Do not assume that because the address is technically valid, it is acceptable to continue using it indefinitely. The company should have a genuine arrangement that allows official correspondence to reach someone acting for the company.

What If I Entered the Wrong Address During Incorporation but the Company Has Not Been Registered Yet?

If your incorporation application has not yet been processed, correcting the application before registration is generally much simpler than correcting the public record afterwards. If you discover the mistake before submission, correct it immediately. If the application has already been submitted but has not yet been processed, check the current Companies House process rather than submitting a second incorporation application for the same business.

Do not create another company merely because you spotted a mistake in the first application. If Companies House rejects the application and identifies the address as the problem, correct the address and resubmit the application as appropriate.

What If I Cannot Access My Old Registered Office?

This can happen when the original address was entered incorrectly or when the founder no longer has access to the premises. The company's authentication code is normally used when changing the registered office online.

Companies House states that if you cannot access the company's registered office, you can request that the authentication code be sent to your home address. The important point is to establish control of the company and use the official Companies House process rather than relying on informal changes.

Does Changing the Address Affect My Company Number?

No. Changing the registered office does not create a new company. Your company continues to have the same:

• Company number
• Legal identity
• Incorporation date
• Share structure
• Directors, unless separately changed
• Shareholders, unless separately changed

The registered office is an important statutory detail, but changing it does not mean that the company itself has been replaced. This is particularly useful for startups that have already opened business accounts, entered contracts or started trading.

What Happens to Mail Sent to the Old Address?

This is one reason you should make the correction promptly. A change of registered office does not instantly make every document sent to the old address irrelevant. The AD01 guidance states that documents can generally still be validly served at the previous registered office for 14 days from the date the change is registered.

For that reason, founders should consider arranging mail forwarding or another appropriate transition arrangement where practical. More importantly, make sure important government and legal correspondence is not missed during the change.

A Practical Address-Correction Checklist

If you discover an address mistake, work through this checklist.

1. Identify the address

Is it the:

• Company's registered office?
• Director's service address?
• Director's residential address?

2. Check the Companies House record

Look at the company's current information and filing history.

3. Check whether the error was original or subsequent

Was the address wrong when you incorporated, or did it genuinely change later?

4. Confirm the replacement address

For a registered office, verify that it is:

• Physically located in the UK
• In the correct UK jurisdiction
• Appropriate for receiving company correspondence
• Capable of recording delivery

5. File the correct notification

Depending on the situation, this may involve:

• AD01 for a company's registered office change
• CH01 for relevant changes to an individual director's details
• A replacement-document process where an earlier filing contains an error

6. Check the public register again

Make sure the change has actually been registered.

7. Update everyone who needs the address

Consider:

• Bank
• Accountant
• Payment providers
• Insurance provider
• Suppliers
• Customers
• Government departments
• Professional advisers

Not every organisation automatically updates its records simply because Companies House has changed.

Common Mistakes to Avoid

Waiting until the confirmation statement

Do not deliberately wait for your next confirmation statement if the registered office has already changed. Companies House requires registered-office changes to be notified separately, and the current guidance says the change should be reported within 14 days.

Assuming the new address is active immediately

The registered-office change takes effect when Companies House registers it.

Confusing registered office with service address

They are different records serving different purposes.

Using a PO Box as the registered office

A PO Box cannot be used as a registered office address under the current rules.

Assuming changing the address deletes the old address

Historical registered-office information can remain on the public record.

Using someone else's address without a proper arrangement

The address needs to meet the relevant requirements and, where applicable, you should have permission to use it.

FAQs

Can I change my registered office address after incorporating a UK company?

Yes. You can change it after incorporation using the Companies House registered-office change process, generally through AD01. Companies House says the change should be reported within 14 days.

Can I change my registered office to an address outside the UK?

Generally, no. The registered office must be a physical address in the UK and must be in the same UK country or jurisdiction in which the company is registered.

Can I use my home address as my registered office?

Yes, provided it meets the applicable requirements, but the registered office is public. If you use your home address, it can therefore become publicly visible on the Companies House register.

Can I use a PO Box as my registered office?

No. Companies House states that a Royal Mail PO Box and similar services cannot be used as the company's registered office address unless the arrangement also provides an appropriate physical address meeting the requirements.

What form do I use to change my company's registered office?

The standard registered-office change is filed using Companies House's online service, commonly referred to as AD01.

What if I entered the wrong address for a director?

First establish whether the address is the director's service address or residential address. If the director's details have subsequently changed, CH01 may be relevant. If the original filing contained an error, a correction or replacement-filing procedure may be required.

Will my old registered office address disappear after I change it?

Not necessarily. Companies House has stated that previous registered office addresses remain on the public register for the lifetime of the company and for 20 years after dissolution.

Can I remove my home address from Companies House?

There are procedures for removing certain home addresses and other personal information from the public register. If your home address was used as an active company's registered office, you generally need to change the registered office first.

Do I need to form a new company because I entered the wrong address?

Usually, no. An incorrect address can normally be dealt with through the appropriate Companies House correction or change process. A registered-office mistake does not by itself invalidate the company's existence.

Conclusion

Entering the wrong address during UK company registration is usually fixable, but the solution depends on which address was entered incorrectly and whether the mistake was present from the beginning or arose later. If the company's registered office is wrong, use the Companies House registered-office change process and make sure the replacement address is appropriate and in the correct UK jurisdiction. If a director's address is wrong, distinguish between the service address and residential address before deciding which correction route applies.

Act promptly, particularly where the old address is no longer accessible or where important legal correspondence could be missed. For founders and global entrepreneurs, getting the address structure right from the beginning can prevent unnecessary administrative work later. A UK company formation and management platform such as IncorpUK can form part of that wider setup process, particularly for founders managing a UK company remotely, but the company remains responsible for ensuring that its statutory information is accurate and kept up to date.

The key takeaway is simple: don't panic and don't form a second company just because an address was entered incorrectly. Identify the exact error, use the correct Companies House procedure, and verify the updated record once the change has been registered.
