How Quickly Does Companies House Update a New Registered Office Address?

If you have submitted a registered office address change to Companies House, you may be wondering how quickly the new address will appear on the public register. For most companies, an online filing is the quickest way to update a registered office address. However, there is no guaranteed fixed number of hours or days for every filing. Companies House advises companies to change their registered office online to update their information as quickly as possible, while paper filings take longer to process.

There is also an important legal distinction: your registered office does not officially change simply because you have submitted the application. The change takes effect when Companies House registers the notice. For founders, that distinction matters. A company may have submitted a new address but still legally have its previous registered office until Companies House registers the change.

How Long Does a Registered Office Address Change Take?

There is no universal guaranteed processing time published by Companies House for every registered-office change. The practical hierarchy is:

Companies House specifically states that online filing is the quicker option, while paper forms take longer to process. So if you need the new address reflected urgently, use the Companies House online service where your company is eligible to do so. The important point is not to rely on a particular promise such as "within 24 hours." Processing can vary, and a filing that requires attention may not appear as quickly as a straightforward online submission.

When Does the New Address Become Legally Effective?

This is the part many company directors misunderstand. The registered office address changes officially only when Companies House registers the change. Submitting the AD01 does not, by itself, complete the process. Companies House's guidance expressly states that the address will not officially change until it has been registered.

Consider this example. You submit your address change on Monday morning. Until Companies House registers that filing, your company's existing registered office remains the official registered office. Once the filing is registered, the new address becomes the registered office. That means there are effectively three stages:

1. You submit the change
2. Companies House processes and registers it
3. The new address becomes the official registered office

This distinction is particularly important when legal notices, contracts or other formal documents are involved.

What Form Do You Need to Change a Registered Office?

For an ordinary UK limited company, the registered office address is changed using form AD01. Companies House provides an online service for changing the registered office, and the AD01 form is also available for companies that need to file by post. The online route is generally preferable because it avoids postal delays and is specifically intended to update company information quickly.

You will normally need access to your Companies House filing credentials and authentication code to complete the online process. Certain companies cannot use the standard online route for example, companies with a default Companies House address, companies in liquidation, and some companies applying for restoration to the register may need to use a paper process.

Does Companies House Have to Be Notified Within 14 Days?

Yes. A company must tell Companies House about a registered office change within 14 days of the change taking place. This requirement should not be confused with the processing time. The 14-day period is the deadline for notifying Companies House. It is not a guarantee that Companies House will take 14 days to update the register.

In practice, you should submit the change as soon as the new registered office is properly arranged. Waiting until the end of the 14-day period creates unnecessary risk, particularly if there is an issue with the filing.

Why Online Filing Is Usually Better

For most eligible companies, filing online is the most efficient option. Companies House itself says you can change the registered office online to update the information as quickly as possible. Online filing can reduce several sources of delay:

• No postal transit time
• No printing or handwriting issues
• Immediate submission
• Easier tracking of the filing
• Faster access to the updated public record once registered

By contrast, paper applications have to reach Companies House before they can be processed. Companies House states that postal filings take longer. For a small business with no special circumstances, there is usually little reason to choose paper filing if the online service is available.

What If the New Address Does Not Appear Immediately?

Don't panic. The first step is to distinguish between submission and registration. If you have just submitted the change, the public register may not immediately show the new address. Give Companies House time to process the filing and check the company's record again. If a significant amount of time has passed and the change still has not appeared, review whether:

• The filing was actually submitted successfully
• You received confirmation of submission
• Companies House has registered or rejected the filing
• There is an issue with the company's filing status
• You used the correct process
• The company is subject to circumstances requiring a paper filing

If you submitted a paper form, allow for postal delivery as well as Companies House processing. The important lesson is simple: do not assume that submitting an application means the register has already changed.

Can You Use the New Address Immediately After Filing?

You should be careful here. Because the change does not officially take effect until Companies House registers it, the old address remains legally significant during the interim period. The AD01 guidance also contains an important protection concerning the previous registered office: a document may still be validly served on the company at its previous registered office for 14 days from the date the change is registered.

That means changing the address should not be treated as an instant switch where everything connected to the old address can simply be abandoned. For practical purposes, keep arrangements in place to deal with correspondence at the previous address during the transition.

What Happens to Mail Sent to the Old Registered Office?

This is one of the biggest practical risks when changing addresses. Even after the new address has been registered, organisations may continue using an old address stored in their records. For example:

• A bank may still have the previous address.
• An accountant may have an old copy of the company's details.
• A supplier may use an old invoice template.
• A customer may have saved your previous address.
• A solicitor may have an address from an earlier contract.

The registered office change at Companies House does not automatically update every private database where your company information appears. Companies House will notify HM Revenue and Customs when an approved registered office change is processed. However, you should still review your wider business records rather than assuming every organisation has automatically updated its systems.

Should You Keep Access to the Old Address?

Yes, if possible, particularly during the transition. This is especially important when the old registered office was provided by a formation agent or virtual office provider. Before ending the old arrangement, check:

• Whether mail forwarding is available
• How long mail will be held
• Whether legal correspondence will be scanned
• Whether there is a forwarding fee
• How long the provider will continue accepting mail
• Whether any termination notice is required

This can prevent a straightforward administrative change from becoming a missed-correspondence problem. For international founders who are not physically based in the UK, this is even more important. A registered office may be the main point through which official UK company correspondence reaches them.

Does Companies House Automatically Update HMRC?

For an approved registered-office change, Companies House says it will tell HMRC that the registered office has changed. That is useful, but it should not be interpreted as "every government or private organisation will now have the new address." Businesses often have several different address records. For example, a company might have:

• Registered office
• Trading or business address
• Director service address
• Correspondence address
• Banking address
• Tax or payroll contact address
• Accountant's records

Changing one does not necessarily change all the others. This distinction becomes particularly important as a company grows.

Does the New Registered Office Have to Be in the Same Part of the UK?

Yes. Your new registered office must remain in the same part of the UK in which the company was incorporated. For example:

• A company registered in England and Wales can move its registered office to another address in England or Wales.
• A Scottish company must keep its registered office in Scotland.
• A Northern Irish company must keep it in Northern Ireland.
• A Welsh company must use an address in Wales.

You cannot simply move the registered office from Scotland to England as an ordinary address change. A move between UK jurisdictions can require re-incorporation rather than a standard registered-office update. This is an important check to make before submitting the filing.

What Makes a Registered Office Address Valid?

Speed should never be the only consideration. The new address must be an appropriate registered office address. Companies House explains that the registered office must be an appropriate address and must be in the same country in which the company is registered.

The practical test is whether documents delivered to the address would reasonably be expected to come to the attention of someone acting for the company and whether delivery can be acknowledged. This is why simply choosing an address from an online directory is not enough. A professional registered-office provider can be useful, but the company should have permission to use the address and a reliable process for receiving official correspondence.

What If Companies House Rejects the Change?

A rejected filing is different from a delayed filing. If Companies House identifies a problem, the address will not become the company's official registered office simply because you submitted the application. Potential problems can include:

• Incorrect information
• An inappropriate address
• Using the wrong filing route
• Issues with the company's status
• An address in the wrong UK jurisdiction

If the address itself is not appropriate, Companies House has powers to take action. Under current rules, it can move an inappropriate registered office to a Companies House default address, and the company may then be required to provide an appropriate replacement address with supporting evidence. Failure to do so can ultimately lead to strike-off proceedings. That is why choosing a legitimate, properly managed registered office matters more than simply finding the fastest address service.

A Realistic Example: Changing From a Formation Agent to a New Office

Imagine Northstar Digital Ltd was incorporated using a professional registered office service. Six months later, the company leases an office and decides to move its registered office there. The directors should not simply stop using the original address. A sensible process would be:

1. Confirm the new office is in the correct UK jurisdiction.
2. Confirm it qualifies as an appropriate registered office.
3. Submit the registered-office change to Companies House online.
4. Wait for Companies House to register the change.
5. Check the public Companies House record.
6. Keep arrangements with the old provider temporarily.
7. Update the bank, accountant, insurers and other important organisations.
8. Update company documents and correspondence where necessary.

The actual filing may be quick, but the complete transition requires more than changing one field on Companies House. That is the distinction experienced company administrators understand.

How to Know When the Change Is Complete

For practical purposes, consider the change complete when:

• Companies House has registered the filing
• The new address appears on the company's public record
• You have confirmed the address is correct
• Important third parties have been notified
• Mail arrangements at the previous address have been dealt with

Do not rely solely on an email saying that a filing was submitted. The critical question is whether Companies House has registered the change.

Frequently Asked Questions

How quickly does Companies House update a registered office address?

There is no fixed guaranteed processing time for every filing. Companies House says online filing is the quickest way to update information, while paper applications take longer. The change becomes official once Companies House registers it.

Can a registered office change appear on Companies House the same day?

It can be processed quickly, particularly when filed online, but you should not assume that every filing will be registered on the same day. Companies House does not provide a universal same-day guarantee.

How long do I have to tell Companies House about a new registered office?

You must notify Companies House within 14 days of the registered-office change taking place.

Does the address change when I submit the AD01?

No. The address does not officially change until Companies House registers the notice.

Is online filing faster than posting an AD01?

Generally, yes. Companies House specifically recommends online filing for faster updating, while paper forms take longer to process.

Can I stop using my old registered office as soon as I submit the change?

You should not assume that you can. The previous address remains important until the change is registered, and certain documents can continue to be validly served at the previous registered office for 14 days after the new address is registered.

Will Companies House automatically tell HMRC?

Yes. Companies House states that it will tell HMRC when an approved registered-office change has been processed.

Can I change my registered office from England to Scotland?

Not through an ordinary registered-office change. The new address must remain in the same UK jurisdiction in which the company was incorporated.

What happens if the new address is rejected?

The registered office does not officially change. You should resolve the issue and provide an appropriate address. Companies House has powers to intervene where an address is not appropriate, including moving a company to a default address in certain circumstances.

Conclusion

Companies House can update a registered office address relatively quickly, particularly when the change is filed online, but there is no universal guaranteed processing time. The key point is that submission and registration are not the same thing. Your company's registered office remains the old address until Companies House registers the new one.

For most companies, the safest approach is straightforward: use the online filing service where available, submit the change promptly, make sure the new address is appropriate and in the correct UK jurisdiction, and check the Companies House record once the filing has been registered.

Do not stop there. Keep the previous address under control during the transition and update banks, accountants, insurers, suppliers and other organisations that hold your company's details. For startups and international founders, this broader approach matters. A registered-office change is not just a Companies House form; it is a change to the address through which important company communications are handled. Getting the filing right and managing everything around it is what makes the transition genuinely complete.
