Moving your business premises is an exciting step forward, but the administrative tasks that follow can often feel overwhelming. If the thought of having to change your address on Companies House brings on a wave of stress-worrying about complex forms, potential penalties, or who else you need to notify-you are not alone. It’s a common concern for busy business owners, and getting it wrong can have real consequences. That’s why we’ve created this simple, straightforward guide to take the worry completely off your hands.
In this article, we’ll walk you through the official step-by-step process for updating your registered office address correctly and efficiently. We will also provide a crucial checklist of every person and organisation you must inform afterwards, ensuring no detail is overlooked. Our goal is to give you the clarity and confidence you need, helping you achieve peace of mind so you can focus on what you do best: running your business.
Understanding Your Registered Office Address: Why It’s So Important
Your company’s registered office is more than just a mailing address; it’s your official, legal home. This is the address that appears on the public record and is used for all formal correspondence from government bodies like HMRC and Companies House. It’s important not to confuse this with your trading address, which is where you conduct your day-to-day business. While they can be the same, they serve very different legal purposes.
Before you decide to change address on Companies House, it’s crucial to understand what this address represents and the rules that govern it. Getting this right from the start can save you a lot of stress and administrative headaches down the line.
The Legal Requirements for a Registered Office
To ensure your company remains compliant, your registered office must meet several non-negotiable legal requirements. These rules are in place to guarantee that official bodies can reliably communicate with your business. The address must be:
- A physical address in the UK. A PO Box number is not sufficient on its own and cannot be used as your company’s registered office.
- In the correct jurisdiction. If your company is registered in England and Wales, the address must also be in England or Wales. The same rule applies to companies registered in Scotland or Northern Ireland.
- Accessible for official mail. You, or a trusted representative, must be able to receive and deal with statutory documents delivered to this address in a timely manner.
The Risks of Using Your Home Address
For many new business owners, using a home address seems like the easiest and most cost-effective option. However, this convenience often comes with significant drawbacks that can cause unnecessary worry. The biggest concern is privacy; your home address becomes publicly available for anyone to find online.
This can lead to several issues, including:
- A loss of personal privacy for you and your family.
- Potential breaches of your tenancy agreement or mortgage terms, many of which prohibit running a business from the property.
- An increase in unwanted junk mail and even the possibility of unsolicited visitors turning up at your door.
Considering these risks is a key part of the process when you need to change address on Companies House. For many directors, the peace of mind that comes from using a separate, professional address is well worth it.
The Official Process: A Step-by-Step Guide to Changing Your Address
When you need to change address on Companies House, you have a legal duty to notify them within 14 days of the move. Failing to do so can lead to complications, so it’s a task best handled promptly. Fortunately, the process is straightforward. You have two official methods: filing online, which is fast and free, or sending a paper form by post. We always recommend the online route for its speed and simplicity-it’s one less thing to worry about.
To file online, you will need your company’s unique 6-digit authentication code. Think of this as your electronic signature, which authorises changes to your company’s official records. Before you begin, it’s also wise to ensure your new location meets the necessary criteria. The government outlines specific rules for registered office addresses, such as it being a physical address in the same part of the UK where your company was registered.
Method 1: Changing Your Address Online (The Easiest Way)
This is the quickest and most efficient way to update your details. The change is usually registered on the public record within 24 hours. Just follow these simple steps:
- Step 1: Head to the GOV.UK ‘Find and update company information’ service and click the “Start now” button.
- Step 2: Sign in to your account (or create one) and find your company by searching its name or registration number.
- Step 3: Once on your company’s overview page, select ‘File for this company’ and then ‘Change registered office address’. You will be prompted to enter your 6-digit authentication code.
- Step 4: Carefully enter your new registered office address and review the details before submitting. You will receive an email confirmation once the change has been accepted.
Method 2: When to Use the Paper Form AD01
While the online method is almost always better, there are rare situations where you might need to use the traditional paper form, AD01. This is typically required if your company is in liquidation or if you are unable to use the online service for any reason. You can download the latest version of Form AD01 from the GOV.UK website. Complete it clearly in block capitals, have it signed by a company director or secretary, and post it to the correct Companies House address listed on the form.
What if You’ve Lost Your Authentication Code?
It’s easy to misplace your authentication code, but don’t worry. You can request a new one via the Companies House online service. The crucial thing to remember is that for security reasons, the new code will be posted to your company’s current registered office address. This means if you no longer have access to the old address, you must plan ahead. The code can take up to 5 working days to arrive, so request it well before you need to make the change.
After You’ve Notified Companies House: Your Essential Checklist
Successfully filing the form to change address on companies house is a crucial first step, but the process doesn’t end there. Failing to update your new address across all platforms can lead to serious problems, from missed legal notices and invoices to a damaged professional reputation. It’s a task that can easily feel overwhelming.
To help you manage this, we’ve created a straightforward checklist. Following these steps will ensure your business operations continue smoothly and without stressful interruptions. We’ve grouped the essential notifications into three key areas: legal, financial, and operational.
Statutory & Legal Notifications
These are non-negotiable updates required to keep your business compliant and legally protected. Missing any of these can result in penalties or other complications.
- HM Revenue and Customs (HMRC): You must inform HMRC separately for Corporation Tax, VAT, and PAYE. They do not automatically receive updates from Companies House.
- Government Gateway: Log in and update the contact details associated with your business account to ensure you receive all official communications.
- Intellectual Property Office (IPO): If your company holds any registered trademarks or patents, update your address with the IPO to maintain legal protection.
Financial & Commercial Updates
Your financial partners and commercial contacts need your correct address to maintain services and trust. An out-of-date address here can disrupt your cash flow and business relationships.
- Business Bank & Lenders: Inform your bank and any loan providers immediately to receive statements and avoid potential security freezes on your account.
- Insurance Providers: Your address can affect your premiums. Notify providers of your public liability, professional indemnity, and other policies to ensure your cover remains valid.
- Payment Processors: Services like Stripe, PayPal, or your merchant account provider require an up-to-date address for verification and billing purposes.
- Suppliers & Key Customers: Ensure your suppliers have the right billing address and your customers know where to send payments or correspondence.
Business & Marketing Updates
Finally, ensure your public-facing information is consistent and professional. This builds trust with potential customers and reflects a well-managed organisation.
- Company Website: Meticulously check and update your address in the website footer, on the contact page, and within your privacy policy.
- Business Stationery: Order new letterheads, invoices, compliment slips, and business cards with the correct details.
- Online Directories & Social Media: Your Google Business Profile is a top priority. Also, update your address on Yelp, industry-specific directories, and all social media profiles.

Frequently Asked Questions
How long does it take for Companies House to process a change of address?
If you submit your change of address online, the update is usually processed very quickly, often within 24 to 48 hours. Postal applications, however, take significantly longer and can take a week or more to be reflected on the public register. For the fastest and most efficient result when you need to change address on Companies House, we always recommend using the online service to avoid any unnecessary delays with your official correspondence.
Is there a fee to change my registered office address?
No, there is no fee to change your company’s registered office address with Companies House. The process is completely free of charge, whether you choose to file the change online or by post. This makes it a straightforward administrative task that you can complete without any cost to your business. We can help you ensure it is filed correctly, taking another small task off your hands and providing you with complete peace of mind.
What is a SAIL address and is it different from a registered office?
Yes, they are different. A registered office is your company’s official address for all formal correspondence from bodies like Companies House and HMRC. A SAIL (Single Alternative Inspection Location) is an optional, alternative address where you can keep your company’s statutory records available for public inspection. While every company must have a registered office, a SAIL address is only used if you prefer not to keep these important documents at your main address.
What are the penalties if I forget to update my company’s address?
Failing to update your address is a serious compliance issue. It is a criminal offence, and directors could face prosecution and fines. Furthermore, if official notices are returned, Companies House may assume the company is no longer trading and could begin the process of striking it from the register. Keeping your details current is a legal requirement that is essential for maintaining your company’s good standing and avoiding any unnecessary stress or legal trouble.
Can my registered office be in Scotland if I live in England?
No, your company’s registered office must be in the same UK jurisdiction where it was incorporated. A company registered in Scotland must have its registered office in Scotland. Likewise, a company registered in England and Wales must maintain its registered office in either England or Wales. You cannot move a company’s registration from one jurisdiction to another (e.g., from Scotland to England) without dissolving the original company and forming a new one.
Do I need to inform HMRC separately, or does Companies House do it?
While Companies House does notify HMRC of the change to your registered office, this does not automatically update all of your tax records. You are still responsible for separately informing HMRC of any changes to your business or trading address for specific services like Corporation Tax, VAT, and PAYE. It is crucial to update HMRC directly to ensure you receive important correspondence and remain fully compliant across all government departments.
