UK company law changed on 4 March 2024. Every company must now keep an “appropriate address” as its registered office, and a bare PO Box no longer qualifies, under the Economic Crime and Corporate Transparency Act 2023 (ECCTA). A registered office address service solves this problem. This guide covers the rules, the verified London costs, and how to choose a compliant provider.
What Is a Registered Office Address Service?
A registered office address service lets a company use a provider’s address as its official registered office. That address receives statutory correspondence from Companies House and His Majesty’s Revenue and Customs (HMRC) while the company trades elsewhere. Companies Act 2006 section 86 requires every UK company to keep a registered office at all times.
The registered office is the official address on the public register. Legal documents can be formally served there. The service is popular with home-based founders, remote businesses, and overseas owners who need a compliant UK address.
Why Do Companies Use a Registered Office Address Service?
Companies use these services for three reasons: privacy, professional image, and compliance handling. Privacy keeps a director’s home address off the public register. A central London address adds prestige. A managed provider handles statutory mail so filing deadlines are never missed. All three matter more now that ECCTA ties provider quality to legal compliance.
What Are the Appropriate Address Requirements Under the Economic Crime and Corporate Transparency Act?
Since 4 March 2024, ECCTA requires an “appropriate address” for every registered office. Companies Act 2006 section 86 sets a two-part test: a document delivered there must be expected to reach a person acting for the company, and delivery must be capable of being recorded by an acknowledgement of delivery. This replaced the old bare registered-office duty.
Enforcement is real. Companies House guidance states that it will move a non-compliant company to a default address, then require an appropriate address with evidence within 28 days. Failure can begin strike-off proceedings.
Can a Registered Office Be a PO Box?
A bare PO Box cannot be a registered office. GOV.UK guidance states you can no longer use a Royal Mail PO Box, or similar third-party services, because delivery there cannot be acknowledged by a person acting for the company. A PO Box that sits inside a full deliverable street address, such as “PO Box 123, 100 Example Street, London EC1A 1AA,” can meet the test, because delivery is acknowledged at physical premises.
What Other ECCTA Changes Affect Your Registered Office?
ECCTA is anti-fraud legislation, so provider choice now carries compliance weight. The reforms go well beyond the address rule, and a compliant registered office service should track all of them.

| Registered email address | A registered email supplied to Companies House, never published | New companies at incorporation; existing companies at next confirmation statement | 4 March 2024 (new); statement date from 5 March 2024 (existing) | GOV.UK confirmation statement guidance |
| Statement of lawful purpose | Confirmation the company is formed and operates for lawful purposes | All UK companies | 4 March 2024 | Companies House blog |

What Is the Difference Between a Registered Office and a Business Address?
The registered office is the single mandatory legal address on the public register. A business address is any operational or trading address with no registration requirement. A company must have exactly one registered office. It can hold multiple business addresses. The UK does not use US-style “registered agent” or “service of process” language, so guidance built around those terms does not apply here.
| Feature | Registered Office | Business / Trading Address |
|---|---|---|
| Legal requirement | Yes, mandatory | No |
| On public register | Yes | Not necessarily |
| Purpose | Statutory correspondence from Companies House, HMRC, and courts | Day-to-day operations, marketing, deliveries |
| Number allowed | Exactly one | Multiple |
| Jurisdiction restriction | Must be in the country of incorporation (England and Wales, Scotland, or Northern Ireland) | No restriction |
| Home address use | Allowed, but then public | Allowed |
| PO Box rules | Bare PO Box not allowed | Generally flexible |
Legal rules above are drawn from Companies Act 2006 and GOV.UK company address guidance.
Can a Director’s Service Address Be Anywhere in the World?
Yes. Every UK company director must give a service address for official personal correspondence. It appears on the public register. It can match the registered office. Unlike the registered office, a director’s service address can be anywhere in the world. Most address services bundle a registered office with a director’s service address. This is a third concept, distinct from both addresses above.
What Is a SAIL Address?
A Single Alternative Inspection Location (SAIL) is an optional address, in the same UK jurisdiction as the registered office, where a company can keep its statutory registers for public inspection. Private companies can instead elect to keep certain registers on the central register at Companies House. The inspection regime is changing under ECCTA digitalisation, so confirm the current position on GOV.UK before you rely on it.
Where Must a Company Display Its Registered Office Address?
A company must display its registered office and registered name on its business letters, order forms, and websites. Companies Act 2006 section 82 and the Company, Limited Liability Partnership and Business (Names and Trading Disclosures) Regulations 2015 set these disclosure rules. The registered name must also appear on business emails and invoices. Missing disclosures can lead to penalties, so keep every document type current after any address change.
Who Needs a Registered Office Address Service for a Limited Company?
Every UK private limited company needs a compliant registered office from day one. The duty in Companies Act 2006 section 86 applies at all times, including to dormant companies and holding companies. Limited liability partnerships (LLPs) carry their own equivalent registered office requirement. Trading status does not change the obligation, so a company with no activity still needs an appropriate address.
Can Non-UK Residents Use a UK Registered Office Address Service?
Yes. Non-UK residents can form and own UK companies, but they must keep a registered office in the jurisdiction of incorporation: England and Wales, Scotland, or Northern Ireland. A registered office address service provides exactly this. Overseas owners often pair it with a resident director service and broader UK expansion support.
There are two overseas routes, and they differ. A UK-incorporated subsidiary is a UK company with its own registered office and filings. An overseas company registering a UK establishment files under a separate Companies House regime for its UK presence. Identity verification under ECCTA hits overseas directors particularly, since verification must be done through GOV.UK One Login or an ACSP.
How Do You Set Up or Change a Registered Office Address with Companies House?
Sign up with a provider, then file form AD01 with Companies House. Online filings typically take effect within 24 hours once Companies House registers them. Changing the registered office is free. You can manage a UK move with Commenda’s change of registered office service.
How Do You Set Up the Service With a Provider?
Choose a provider, complete identity and know-your-customer (KYC) verification, and sign the service agreement. The provider issues documentation proving your right to use the address. Keep that proof, because Companies House can demand evidence of a link to the address during enforcement.
How Do You File Form AD01?
File form AD01 online through Companies House WebFiling. You need your company authentication code or authorised filer access. The public record updates within roughly 24 hours of a successful online filing. Confirm the new entry appears on the register before you update anything else.
Who Else Must You Notify?
Notify HMRC for corporation tax, and update your Value Added Tax (VAT) registration if applicable. Tell your bank, suppliers, and clients. Update letterheads, order forms, and your website to keep disclosure rules met. A compliance calendar helps track each notification.
What Is the Jurisdiction Rule?
The registered office cannot move between UK jurisdictions with a simple change. You cannot shift a registered office from Scotland to England, or the reverse, because that changes the company’s jurisdiction. That move requires re-registering the company, not filing form AD01.
How Much Does a Registered Office Address Service in London Cost?
Verified London registered office services start from around £39 per year. A London address carries no legal advantage over a Manchester or Edinburgh one; the benefit is purely reputational. The table below lists only providers whose annual or monthly price was confirmed on their live pricing page in July 2026.
| Provider | London location | Starting price (verified) | Mail handling | Compliance notes | Source and date verified |
|---|---|---|---|---|---|
| 1st Formations | 71-75 Shelton Street, Covent Garden, WC2H 9JQ | £39/year | Statutory mail scanned and emailed same day, free; originals posted on | Operates an appropriate-address service | 1stformations.co.uk, July 2026 |
| Quality Company Formations | 71-75 Shelton Street, Covent Garden, WC2H 9JQ | £39/year plus VAT | Registered office mail scanned and emailed same day, free | Operates an appropriate-address service | qualitycompanyformations.co.uk, July 2026 |
| Hoxton Mix | 66 Paul Street, London EC2A 4NA | From £21/month billed annually | Digital mail scanning; UK mail forwarding add-on £17/month | States Companies House and HMRC compliance | hoxtonmix.com, July 2026 |
Two providers were reviewed and excluded. Elemental CoSec (27 Old Gloucester Street, WC1N 3AX) publishes no clear base annual price on its live page. Your Virtual Office London advertises only a per-week figure that obscures the annual cost. Neither could be verified against a published annual price, so neither appears above.
What Should You Look for in a Registered Office Address Service Provider?
Pick a provider that can demonstrate appropriate-address compliance, handles all statutory mail with delivery acknowledgment, and publishes transparent renewal pricing. Ideally it holds ACSP registration under ECCTA. Ask directly, because an address provider may or may not be an ACSP. That distinction now signals AML supervision and identity-verification capability.
Avoid providers that forward only some mail, cannot confirm delivery, or raise prices without notice. Companies House has warned about services that fail to meet appropriate-address standards. Check jurisdiction coverage, notice periods, and what happens on cancellation, since you must have a new appropriate address ready to avoid strike-off.
How Do Mail Forwarding and Mail Scanning Work with a Registered Office Address?
Providers receive statutory mail, then scan and email it, upload it to a digital portal, or physically forward it. Statutory-mail forwarding is often free, while general business mail and international forwarding cost extra. Scanning with timestamps supports the ECCTA requirement that delivery be recorded, so a good scan-and-notify system is part of being an appropriate address, not just a convenience.
Mail forwarding means physical re-posting of items. Mail scanning means digital delivery of the contents. Same-day scanning matters most for statutory deadlines. Confirm turnaround times and notification method before you commit.
Is a Virtual Office the Same as a Registered Office Address Service?
No. A registered office service covers only the statutory address and official mail. A virtual office is a broader bundle. It adds telephone answering, meeting room access, coworking day passes, and full handling of general business mail, at a higher price. A virtual office can include a registered office, but the two are not synonyms.
What Do Company Secretarial Services Add?
Company secretarial services handle ongoing statutory compliance. They cover confirmation statements, statutory registers, board minutes, and filings. The same providers often bundle them with address services. This is a distinct offering from both the registered office address and the virtual office, and it is where filing deadlines are actually managed.
What Are Common Mistakes When Using a Registered Office Address Service?
The costly mistakes are choosing a non-compliant provider, failing to notify HMRC and stakeholders after a change, ignoring service limitations, not monitoring scanned mail, and having no contingency if the provider closes or moves. Post-ECCTA, a cheap non-compliant provider can get your company struck off, so price is not the only factor.
Watch for address-misuse fraud. Fraudsters sometimes register companies at addresses they do not control. Monitor how your address is used and report suspicious activity to your provider and Companies House. Remember that your registered office is public and searchable on the register, so weigh privacy before you choose an address.
