Why Updating Your Company Address is Critical for Compliance

Company address compliance sounds like the dullest part of running a business, until something goes wrong. Your registered office is where the law assumes your company receives official letters. If that address is out of date, the company can miss a court claim, a tax demand or a strike-off warning without ever seeing it, and the consequences still apply. This guide explains why company address compliance matters, what the rules now require, and how to keep your addresses right.

The addresses a company has

Several different addresses can be linked to a company, and each has its own rules:

• Registered office address: the company's legal address, shown on the public register.
• Trading address: where the business actually operates, if different.
• Directors' service addresses: public addresses where directors can be contacted, often the registered office.
• Directors' residential addresses: held privately by Companies House.
• PSCs' service and residential addresses: treated the same way as directors'.
• Registered email address: a private email for Companies House to contact the company.

Company address compliance means keeping all of these accurate, not just the registered office.

Reason 1: Legal documents are treated as delivered

Documents sent to your registered office are generally treated as served on the company, whether or not anyone reads them. That includes:

• claim forms and court papers
• statutory demands and winding-up petitions
• letters from Companies House about overdue filings or strike-off
• HMRC notices and penalty letters

If the address is wrong, a creditor can obtain a court judgment against the company without the directors ever knowing a claim was made. By the time they find out, enforcement may already have started, and setting the judgment aside costs time and money.

Reason 2: The appropriate address rules

Since 4 March 2024, every registered office must be an appropriate address. In the ordinary course of events, documents delivered there must be expected to come to the attention of someone acting for the company, and delivery must be capable of being recorded by an acknowledgement. A PO box alone does not qualify, and nor does an address where nobody will ever collect or sign for post.

Not having an appropriate address is an offence for the company and its officers. So company address compliance is no longer just good practice; it is a legal requirement in its own right.

Reason 3: Companies House can move you to its default address

If Companies House is satisfied that a registered office is not appropriate, for example because post is being returned or someone reports that the company is not there, it can change the company's registered office to a Companies House default address. That is a serious step:

• post sent to the default address is not forwarded to you
• the register shows that your company was moved to the default address, which looks bad to anyone checking
• if you do not then provide an appropriate address, Companies House can begin action to strike the company off

Moving back from the default address needs a specific application with supporting information, not just a normal online change.

Reason 4: Strike-off and frozen bank accounts

Companies House writes to the registered office before it strikes a company off for not filing accounts or confirmation statements. If those letters go to an old address, the first a director may hear is that the company has been dissolved. At that point:

• the company's bank accounts are frozen
• its assets pass to the Crown as ownerless property
• contracts may be affected and customers may stop paying

Restoring a company is possible, but it costs far more than keeping the address right in the first place.

Reason 5: Missed tax letters

HMRC uses the addresses it holds to send notices to file, penalty notices and compliance letters. Missing them can mean penalties building month after month. Good company address compliance includes checking the addresses HMRC holds for Corporation Tax, PAYE and VAT, not only the Companies House record.

Reason 6: Trading disclosure rules

A company must display certain details where it does business and in its communications. Its business letters, order forms and websites must show:

• the company's registered name
• its registered number
• the part of the UK where it is registered
• its registered office address

The company name must also be displayed at the registered office and at any place of business, unless that place is mainly someone's home. Out-of-date addresses on your website footer or invoices break these rules, and repeated failures can be an offence.

Reason 7: Banks, lenders and customers check

Banks run checks against the Companies House register when opening and reviewing business accounts. Lenders, insurers and larger customers do the same. An address that does not match your real position, or a history of default-address flags, raises questions and can delay accounts, credit and contracts.

Situations that cause address problems

Company address compliance usually slips during a change, not in a normal week. Watch for these moments:

Moving out of an office

The lease ends and the team moves on, but the registered office stays at the old building. Post piles up with a landlord who has no reason to forward it. Change the registered office before you hand back the keys, and arrange forwarding for the 14 days after the change, when documents can still be served at the old address.

A virtual office provider closes or you stop paying

If your registered office is provided under a contract and that contract ends, the address stops being appropriate straight away. Providers may also tell Companies House that you are no longer there. Move to a new provider or another address before the old service ends.

Changing accountants

Many companies use their accountant's office as the registered office. When you move to a new accountant, the old firm may stop accepting post for you. Agree a date and file the change.

A director moves house or abroad

The director's residential address must be updated with Companies House within 14 days. If their home was also the registered office, the company needs a new registered office in the right part of the UK, because a registered office cannot be outside the UK.

The business is dormant

Dormant companies still receive official letters, and are often the ones whose addresses go stale because nobody is watching. A dormant company still needs an appropriate registered office and must keep filing.

Keeping your home address private

Company address compliance and privacy go together. Many people start a company using their home as the registered office and as their director's service address, which puts their home on the public register. Once filed, earlier records cannot simply be deleted. Using a professional registered office and service address from the start protects your privacy while meeting the rules. Our virtual office service gives you a compliant registered office address.

How to update your address

To change your registered office, file form AD01 with Companies House within 14 days of the change taking place. It is free online. The new address must be appropriate and in the same part of the UK as the company is registered. Directors' and PSCs' address changes are filed separately on forms CH01 and PSC04. Our step-by-step guide on how to change your registered office address covers the process in full.

A company address compliance checklist

• Is your registered office an appropriate address where post is received and acknowledged?
• Does someone check post there at least weekly?
• Is the address in the right part of the UK?
• Is your registered email address monitored?
• Are directors' and PSCs' service addresses current?
• Do your website, invoices and emails show the right company details?
• Do HMRC's records match your current addresses?
• Have you told the bank and insurers about any move?
• Is there a named person responsible for opening and acting on post at the registered office?

What if you have already missed something?

If you discover that post has been going to an old address, act quickly. File the address change, then check the register and HMRC records for anything you may have missed: overdue filings, penalty notices, or a pending strike-off notice in the Gazette. If a court judgment has been entered against the company, take legal advice straight away, because there are time limits for applying to set it aside.

Company address compliance: key points

• Letters to your registered office count as delivered, even if you never see them.
• The registered office must be an appropriate address by law.
• Companies House can move a company to its default address, which can lead to strike-off.
• Business letters, websites and order forms must show your company details.
• A professional address protects your privacy while keeping you compliant.
• Review all your company addresses whenever the business moves, changes adviser or changes provider.

The official rules are on GOV.UK: rules for registered office addresses and email addresses.
