Keep Your Registered Office and Company Records in Order
Maintaining accurate registered office details and organised company records supports effective business administration. We help you prepare and submit relevant Companies House notifications when your registered office address, record-keeping location or registered jurisdiction changes, where permitted.
Whether you are relocating, updating where records are available for inspection or reviewing your existing arrangements, we guide you through the information and documentation required. Our practical support helps you coordinate updates, maintain consistency across your records and keep official correspondence directed to the right place, giving you confidence that your company’s administrative details remain current.

Frequently Asked Questions
Let’s Discuss Your Requirements

Does a Registered Office Change Apply as Soon as the Form Is Filed?
No, filing the form does not change your registered office straight away. The change only takes effect once the Registrar has registered the notice. Until that happens, your previous address remains your official registered office, so you should keep receiving and checking post at the old address.
Which Form Do I Use to Change My Registered Office Address?
You need to file form AD01, which is the Change of Registered Office Address, with Companies House. The form asks for the new address and must be completed in full so the Registrar can register it. Official letters and legal documents will be sent to your registered office, so it is important to make sure the address is correct and that someone can receive post there.
Can I Move My Registered Office to Any Address?
No, your new registered office address must be in the same part of the UK where the company was originally registered. For example, a company registered in England and Wales must have a registered office address in England or Wales. The same rule applies to a Single Alternative Inspection Location (SAIL), so you should check the location before you file.
What Is a SAIL and How Do I Notify Companies House?
A SAIL is a Single Alternative Inspection Location, which is an address where your company can keep certain records for public inspection instead of at its registered office. To tell Companies House about it, you need to file form AD02, which is the Notification of Single Alternative Inspection Location. The SAIL must be in the same part of the UK as the company’s registration, and only one alternative location can be used.
How Do I Change Where My Company Records Are Kept?
To move your company records to the SAIL, you need to file form AD03, which is the Change of Location of the Company Records to the SAIL. To move them back to your registered office, you must file form AD04 instead. AD03 must be filed together with AD02 if the SAIL has not been notified before, and AD04 must be filed together with AD03.
What Is Form AD05 Used for?
Form AD05 is the Notice to Change the Situation of an England and Wales Company or a Welsh Company. It is used to change a company’s registered situation between England and Wales and Wales, which affects the jurisdiction where the company is registered. This form is separate from AD01, which changes only the registered office address, so choosing the right one is important.
What Is the Deadline for Filing AD05?
When a company changes its situation, it must pass a special resolution to approve the change. A copy of that special resolution must reach the Registrar within 15 days of the date it was passed. Filing late can cause delays or complications, so you should prepare your documents as soon as the resolution is agreed.
Can an LLP Use Form AD01?
No, form AD01 cannot be used by a limited liability partnership, because it is designed for companies. LLPs must use form LL AD01 to change their registered office address instead. Using the correct form is important, as Companies House may reject a filing that is submitted on the wrong version.
