How to Change Your Company Address on Companies House: A Step-by-Step 2026 Guide

Last month, a business owner in Alloa discovered that failing to update their records within 14 days could lead to a fine of up to £5,000. It’s a stressful realization when you’re already juggling the logistics of a physical move. You want to focus on your growth, not paperwork. If you need to know how to change address on Companies House while protecting your personal privacy, you’ve come to the right place.

We understand that the distinction between a registered office and a trading address often feels like unnecessary jargon. Our goal is to take that burden off your hands. This guide walks you through the 2026 process for updating your details, ensures you meet the strict 14-day deadline, and clarifies exactly who else needs to know about your new location. You’ll move forward with more time, more money, and more mind (less stress !!!!!!).

What is a Registered Office Address and why must you update it?

Your registered office address (ROA) is much more than just a line on a form. It’s the official home of your limited company for all legal and statutory correspondence. Think of it as the primary point of contact for the UK government. This is where Companies House and HMRC send formal notices, tax reminders, and legal documents. Since this address is on the public register, anyone can look it up at any time. This provides essential transparency for your customers, suppliers, and the general public. In a database of over 5 million active companies, maintaining an accurate record is how you prove your business is active and legitimate.

When you move your business, you can’t just pack the boxes and leave the paperwork for later. The law is very clear on this point. Under Section 87 of the Companies Act 2006, you must notify the registrar within 14 days of changing your address. Failing to do so isn’t just a minor oversight; it’s a breach of your statutory duties as a director. Knowing exactly how to change address on Companies House ensures you remain compliant and keeps your business running smoothly. It prevents the stress of missed deadlines and ensures your “three freedoms”-time, money, and peace of mind-stay protected while you focus on growth.

The public nature of the ROA is a key factor to consider. Every detail you provide is visible on the Government’s digital service. This transparency helps build trust with 85% of consumers who prefer to verify a business’s credentials before making a purchase. However, it also means that using your home address might lead to unwanted privacy issues. Many directors choose to use a professional service address to keep their personal life separate from their business operations. This is a practical way to manage your public profile while meeting legal obligations.

Registered Office vs. Trading Address

Your trading address is where the daily work happens. It’s where you meet clients or manufacture products. Your ROA, however, is specifically for official mail. These two can be the same, but they don’t have to be. Many of our clients use our office address in Alloa or Stirling as their ROA to keep their home address private. You might also use a Single Alternative Inspection Location (SAIL). This is a specific place, other than the ROA, where you keep statutory records like the register of members. Having a SAIL address gives you flexibility in where you store 100% of your legal company books.

The Legal Consequences of Non-Compliance

Neglecting your statutory updates can lead to serious headaches. If your records aren’t updated within that 14-day window, you could face personal fines of up to £5,000. Beyond the financial penalty, you risk missing critical HMRC deadlines. If a VAT notice or a corporation tax demand goes to an old address, you won’t see it. This leads to late payment penalties that start at £100 and escalate for every month of delay. An outdated address also damages your credit rating. Credit reference agencies check the public register daily; if they see inconsistencies, it signals poor management and can make securing a business loan nearly impossible. Learning how to change address on Companies House is the simplest way to avoid these avoidable risks.

How to change address on Companies House: The Step-by-Step Process

Updating your business records doesn’t have to be a headache. Whether you’re moving to a larger office in Stirling or transitioning to a remote setup, the process of learning how to change address on Companies House is straightforward once you have the right tools. We’ve broken this down into five manageable steps to give you more mind (less stress !!!!!!) during your move.

• Step 1: Locate your Company Authentication Code. This is a 6-digit alphanumeric code unique to your company. Think of it as your digital signature. You’ll need this to access your records on the official Companies House website.
• Step 2: Log in to the online filing service. Use your registered email address and password to enter the Companies House WebFiling portal. If you haven’t used this before, you’ll need to create an account first.
• Step 3: Select Form AD01. Once you’ve entered your company number and authentication code, look for the option labeled ‘Change of registered office address’. This is officially known as Form AD01.
• Step 4: Enter and submit details. Type in your new full UK address. Double-check the postcode for accuracy, as a single typo can lead to a rejection. Hit submit to send the electronic form directly to the registrar.
• Step 5: Wait for confirmation. Companies House typically sends a confirmation email within 24 hours. Once you receive this, your new address is legally active on the public register.

Online Filing vs. Paper Form AD01

In 2026, 99% of UK business owners choose online filing because it’s significantly faster. While digital submissions are usually processed in under 24 hours, paper forms can take 10 working days or longer to handle. However, certain situations require the physical AD01 PDF. If your company is currently in liquidation or undergoing a restoration process, digital filing might be restricted. You can download the form from the government website and post it to the relevant registrar. For companies registered in England and Wales, send it to Cardiff. Scottish companies must mail theirs to Edinburgh, while Northern Ireland firms use the Belfast office.

What to do if you’ve lost your Authentication Code

Losing your authentication code is a common cause of anxiety, but it’s a problem we can help you solve easily. You can request a new code through the WebFiling login page. For security reasons, Companies House only posts this code to the current registered office address on file. This ensures that only authorized personnel can make changes to the company. If you’ve already moved and no longer have access to your old office’s post, you’ll need to act quickly. You may need to contact Companies House directly or use a professional service to take it off your hands and manage the transition manually. Most replacement codes arrive via Royal Mail within 5 working days.

Geographical Rules and the ‘Scotland Factor’

You might think moving your business from Stirling to London is as simple as updating a digital form. It isn’t. The UK operates under three distinct legal jurisdictions for company registration: England and Wales, Scotland, and Northern Ireland. According to the Companies Act 2006, your registered office address (ROA) must stay within the same part of the UK where you first incorporated the business. This is known as the ‘Same Country’ rule, and it’s a strict legal boundary that catches many directors off guard.

Let’s look at a practical example. If you move your physical office from Stirling to Alloa, it’s a 15-minute drive and a straightforward update. Both locations are in Scotland, so you just follow the standard process for how to change address on Companies House. However, if you decide to move your entire operation from Stirling to London, you hit a legal wall. You cannot simply ‘change’ a Scottish registered office to an English one. Companies House won’t allow a company to hop between jurisdictions on a single form because the underlying legal framework governing your company changes when you cross the border.

If your business physically relocates long-distance, you have two main options. You can keep a ‘nominal’ registered office in Scotland while your team works in England. Alternatively, you can go through a complex re-incorporation. This usually involves closing the Scottish entity and starting a brand-new company in England. This process is messy, triggers tax implications, and requires new contracts for every supplier. Most of our clients prefer to keep their legal base stable in Scotland to avoid this unnecessary stress.

Incorporation in Scotland

You can easily check if your business is tied to Scottish soil by looking at your company number. If it starts with an ‘SC’ prefix, you’re a Scottish company. This means your legal headquarters must physically exist within Scotland’s borders. Whether you’re operating from a home office in the Highlands or a shop in the Borders, your official post must have a Scottish destination. At Stewart Accounting Services, we provide local hubs in Alloa, Stirling, and Falkirk to ensure our clients meet these residency requirements without having to maintain a physical storefront themselves.

Using a Professional Registered Office Service

Many business owners use our office address as their official ROA to satisfy the ‘same country’ requirement. This is a smart move if you want to move your physical operations anywhere in the world while keeping your legal status stable. If you decide to move your actual workshop to Cornwall, you don’t need to worry about how to change address on Companies House for the legal entity as long as your ROA stays with us in Central Scotland.

This service also offers significant privacy advantages. Using your home address means anyone can find your front door on the public record with a few clicks. By using a professional service, you keep your personal life private. We handle the official mail, scan it, and send it to you immediately. It takes the burden off your hands and ensures you never miss a deadline from HMRC or Companies House. It’s a simple way to gain more ‘mind’ and less stress while keeping your business compliant.

Beyond the AD01: Who else needs to know you’ve moved?

Filing the AD01 form is the legal baseline for your transition. While you now understand how to change address on Companies House, this action doesn’t automatically sync with every other institution. Data from the Office for National Statistics suggests that nearly 85% of UK small businesses miss at least one critical notification during a relocation. This leads to missed mail, late fees, or even legal non-compliance. You’ve got to be proactive to protect your “three freedoms” and keep your business running without unnecessary friction.

Banks are notoriously strict about address changes. Most high-street lenders won’t accept a simple phone call or email. They typically require a formal board minute, signed by the directors, confirming the change of Registered Office Address. Without this, your bank statements and sensitive financial correspondence will continue to arrive at your old premises. If your mail falls into the wrong hands, you risk a data breach under GDPR guidelines, which could lead to significant fines from the Information Commissioner’s Office.

Insurers are equally demanding. Your Professional Indemnity or Public Liability premiums are often calculated based on your specific postcode and office security. If you move from a quiet office in Alloa to a busier hub in Stirling without notifying your provider, they might view this as a material change in risk. Industry data indicates that up to 60% of insurers may initially dispute a claim if the business location on the policy doesn’t match the actual site of the incident.

Updating HMRC for VAT and PAYE

HMRC doesn’t always talk to Companies House in real time. You must manually update your VAT registration through your Government Gateway account within 30 days of the move. Under the Finance Act 2008, failing to notify HMRC of changes to your business details can result in a £50 penalty. For payroll, you need to update your “Business Address” to ensure tax codes and P60s remain accurate for your team. We’ve seen instances where a simple address mismatch across government departments delayed a VAT refund by more than 14 days, causing avoidable cash flow stress.

Stationery and Digital Presence Checklist

The Companies Act 2006 is very clear: your registered office address must appear on your website, invoices, and all official business letters. It’s a legal requirement, not a stylistic choice. For business owners in Central Scotland, updating your Google Business Profile is vital for maintaining local SEO. If your profile shows an old address in Falkirk while your website lists a new one in Stirling, Google’s algorithm may penalize your local search visibility by as much as 20%.

• Invoicing Software: Update your templates in Xero or QuickBooks immediately to ensure your invoices remain legally valid.
• Digital Footprint: Check your email signatures, social media “About” sections, and website footers.
• Physical Assets: Audit your business cards, letterheads, and any branded promotional materials.
• Suppliers: Notify utility companies and trade suppliers to ensure invoices and deliveries reach the right place.

Frequently Asked Questions

Can I use my home address as my registered office on Companies House?

Yes, you can use your home address as your registered office. It’s a common choice for the 15% of UK small business owners who run their operations from a home study. You should be aware that this address becomes public record, meaning anyone can find it on the register. Many of our clients prefer to use a professional service to keep their home life private and reduce the volume of business mail at their front door.

How much does it cost to change my company address?

It costs £0 to update your registered office address directly with Companies House. There are no government filing fees for this service whether you file online or use a paper form. If you’d like us to take it off your hands, an accountant might charge a small administrative fee to ensure the filing is handled accurately. This small investment ensures your records are perfect without you having to navigate the government portals yourself.

How long does it take for the new address to show up on the register?

Online submissions usually appear on the public register within 24 hours. If you decide to send a paper form by post, it can take up to 10 working days for the staff at Companies House to process the update. Learning how to change address on Companies House through the digital portal is the fastest way to see the results. Once the system updates, the new details are visible to the public immediately.

Do I need to tell HMRC if I change my address on Companies House?

Yes, you must notify HMRC separately to update your Corporation Tax and VAT records. While both are government bodies, their computer systems don’t always talk to each other automatically. You should update your details through your HMRC online account within 30 days of the change. Keeping both records in sync prevents missed tax deadlines and ensures your official correspondence reaches you at the correct location.

What happens if I move my business from Scotland to England?

You cannot move a company’s registered office jurisdiction from Scotland to England or Wales. Under the Companies Act 2006, a company must keep its registered office in the country where it was first incorporated. If your business started in Stirling or Alloa, your official office must remain in Scotland. To change this, you would typically need to set up a new company in the new country and transfer your business assets over.

What is an AD01 form and where do I find it?

The AD01 is the specific paper form used to tell Companies House that your registered office address has changed. You can download a PDF version of this form directly from the GOV.UK website. It’s a simple two page document that requires your company number and the new address details. While 85% of businesses now file digitally, the AD01 remains a reliable option if you don’t have access to the online filing system.

Can I change my company address if I don’t have an authentication code?

You can’t use the online filing system without your 6 digit alphanumeric authentication code. If you’ve lost yours, you can request a replacement through the Companies House website, which arrives by post at your current registered office within 5 working days. If you’re in a hurry and don’t have the code, you’ll need to use a paper AD01 form. Knowing how to change address on Companies House via post is the only workaround when your digital credentials are missing.
