Has Companies House changed your registered office address to a default address? Don’t panic, but don’t ignore it either. Here’s why you might be seeing the dreaded Companies House default address, what to do next, and what happens if you don’t sort it out.

Your registered office address might feel like one of those boring bits of company admin you set up and then promptly forget about. But if Companies House decides that your registered office isn't appropriate, it can change it to a default address – and that's when you'll want to start paying attention.

So, why might Companies House have changed your address in the first place?

What is the Companies House default address?

The Companies House default address is essentially a fallback address used when Companies House decides that a company's registered office isn't appropriate. The exact address used depends on the jurisdiction in which your company is registered.

For an England and Wales company, you'll see an address along the lines of:

PO Box 4385, [Company number] - Companies House Default Address, Cardiff, CF14 8LH.

It isn't intended to be a permanent alternative to having your own registered office. If you've found this address on your company's record, the next question is probably why it happened.

Why has Companies House changed my registered office address?

Companies House requires every Limited Company to have an ‘appropriate registered office address’. This means that, in the ordinary course of events, documents delivered to the address should be expected to reach someone acting on behalf of the company, and delivery should be capable of being acknowledged. If Companies House decides that your registered office isn't appropriate, it can change it to a Companies House default address.

One of the most common situations is where someone challenges your company's use of the address. For example, you might be using an address without the permission of the person or business that owns or occupies it. They can make a complaint to Companies House using an RP07 form, which is used to apply to change a company's disputed registered office address.

What to do if someone disputes your registered office address

If someone files an RP07 claiming that your business doesn’t have the right to use your registered office address, don’t panic. But do take action. Companies House may give you 14 days to object to the application and provide evidence that your address is appropriate. In some circumstances, the registrar can change the registered office to the default address without giving this notice period.

Here’s what you need to do:

1. Identify the issue: Figure out why your registered office address was deemed unsuitable, or why the RP07 was filed against you. This might mean contacting Companies House for clarification. If there’s been a misunderstanding, the applicant may agree to withdraw their application. 

2. Provide proof of permission: If you do have evidence that you have legal permission to use your registered office dress (such as a contract, proof of payment or other legal documents), you’ll have 28 days to gather and provide this proof and send it to Companies House.

3. Update your address: If you aren’t authorised to use the address you had previously registered with, you’ll need to find and provide a new registered office address that does meet the legal requirements. 

4. Inform your stakeholders: If you are providing a new registered address, make sure to let clients, suppliers and other key contacts know about your updated address to avoid any confusion.

5. Seek help from a professional: A professional can not only help you register a suitable new address, they can help you with everything else you need to know to be a compliant limited company. When you use Crunch’s Limited Company service, our experts will help you stay on top of filing deadlines and statutory obligations, and manage all of the legal requirements from Companies House. 

Other reasons why you might get given the dreaded default

1. They haven’t been able to deliver mail to the address you registered with

If mail from Companies House and HMRC sent to your registered office address is repeatedly returned as undeliverable, Companies House might use the default address as a last resort.

2. You provided an invalid address

If the address you provide doesn’t meet the criteria - for example, if it’s not a physical address in the UK - you’ll likely get the default address instead.

3. You forgot to update your company details

If your company moves or changes its registered office address but you don’t notify Companies House, they may redirect your mail to the default address.

I've been given the Companies House default address. What do I do now?

If you've already spotted the Companies House default address on your company's record, this is the section to pay attention to. Once Companies House has changed your registered office to the default address, you generally have 28 days to provide notice of a new registered office address, unless you've appealed the decision. You'll need to provide evidence that you own or have permission to use the new address.

So, what should you actually do?

1. Check why the address was changed

Start by checking your Companies House record and any correspondence you've received. If someone has challenged your use of the address, work out whether you can prove that you have permission to use it. If you can, gather the relevant evidence. If you can't, don't waste valuable time trying to defend an address you're not entitled to use. Start looking for a suitable replacement instead.

2. Find a suitable new address

You don't necessarily need to use your home address. You could use:

• Your business premises.
• Another property you own.
• An address you have permission to use.
• A professional registered office service.

Crunch customers can get a discount on Hoxton Mix's digital registered office address service, which can be a useful option if you need to replace an address that Companies House has rejected. Whichever option you choose though, make sure the address meets Companies House' requirements and that you have permission to use it.

3. Change your registered office

If your company has been moved to the Companies House default address, there is a specific process for changing it. You'll need to use the change registered office address form for a company with a default address, rather than the standard online service used by most companies.

You'll also need to provide evidence that the new address is appropriate and that you own or have the right to use it.

4. Don't leave it until the deadline

This is one piece of company admin where ignoring the problem can make things considerably worse. If you don't provide a new appropriate registered office address within 28 days, Companies House may begin the process of striking your company off the register. The registrar can publish a Gazette notice stating its intention to strike the company off, and if the situation isn't resolved, the company can ultimately be struck off and dissolved.

Why you don’t want the Companies House default address

At first glance, the default address might seem harmless. After all, it’s just an address, right? Not quite.

Being assigned the default address can cause serious issues, including:

• Missed correspondence: You could miss critical letters from Companies House or HMRC, leading to fines or compliance problems.
• Damage to your reputation: A default address on public records can make your business look unprofessional or unreliable. Particularly with investors and banks.
• Legal complications: Using an inadequate address or failing to respond to important notices can escalate into more serious problems.

How to avoid the Companies House default address

The good news? Avoiding the default address is straightforward if you follow these best practices:

1. Choose a reliable registered office address

The easiest way to sidestep issues is by choosing a suitable registered office address (that you have expressed legal permission to use) from the start. Make sure it:

• Is a physical location in the UK (PO boxes alone don’t count)
• Can receive mail during standard business hours
• Is an address you have permission to use

Many small business owners use their home address as their registered office, but this means it will appear on the public register. If you'd prefer to keep your personal address private, Hoxton Mix offers a virtual office service that provides a professional registered office address for just a small amount per month or included with a Limited Premium plan. This service masks your personal details on Companies House and includes handling all company post, which is scanned and emailed to you. 

As a Crunch client, you’ll also save on the normal monthly costs for Hoxton Mix. For more details check out this article which explains how it works.

In short, there’s never any reason to feel you cannot provide a suitable registered office address. If you’re looking for more tips and guidance on picking the right location, we’ve broken down how to choose the right registered office address here. 

2. Regularly check your mail

Make sure you’re checking your office mailbox often enough that you can promptly read and action any important messages from Companies House and HMRC.

3. Keep Companies House updated on any changes in your business

If your company changes address, notify Companies House as soon as possible. You can update your registered office address online, and the change is typically processed quickly.
‍

What if I think Companies House has got it wrong?

If you believe your existing registered office is appropriate and you have the right to use it, you may be able to challenge the decision. If Companies House has changed your registered office to the default address, the company can appeal the registrar's decision to the court. The appeal must generally be made within 28 days of being given notice that the registered office has been changed.

This is one of those situations where getting professional advice can be worthwhile, particularly if there's a dispute over who has the right to use the property.

What if someone is using my address?

This can happen too. Imagine checking Companies House and finding a company you've never heard of registered to your home address. You haven't given them permission, but now their official company correspondence could be turning up at your door.

You don't have to simply put up with it. Companies House has a process for reporting the use of your address without permission. You'll need to provide evidence showing that the address belongs to you or that you have rights to use it. Examples include property documents, a written agreement or a recent utility bill.

Don’t end up with the default - it’s not worth the hassle!

Put simply, the Companies House default address is no replacement for having a proper registered office address. Making sure you have clear, written permission to use your registered office address - and keeping your details accurate and up-to-date - is a straightforward but crucial step to staying compliant and protecting your business’ reputation.

If you need guidance, don’t hesitate to get expert advice. A little time and effort now can save you a lot of stress later. After all, your registered office isn’t just a legal requirement - it’s a cornerstone of your business’s credibility and compliance.
