The registered office address, explained

It’s the company’s legal letterbox: where Companies House, HMRC and the courts serve documents. Miss a strike-off warning or a county court claim because nobody checks the registered office post, and the consequences are entirely yours — the law assumes delivery there reached the company. That’s the practical reason the address must be genuinely monitored, not just valid on paper.

The Economic Crime and Corporate Transparency Act tightened the rules from March 2024. A registered office must be an address where:

• a document delivered would come to the attention of a person acting for the company, and
• delivery can be acknowledged

A PO Box on its own no longer qualifies. Companies House can change a non-compliant address to a default address itself — and a company that doesn’t then provide a proper one risks strike-off. The same reforms added the (non-public) registered email address requirement.

• Home: free and simple, but public forever and mixes official post with household post
• Your business premises: fine if someone reliably opens the post
• Accountant’s address: keeps your home private and puts official post in front of the people who act on it — the most common choice for owner-managed companies

What’s forgotten is everything downstream — HMRC (Corporation Tax, PAYE and VAT records are separate), your bank, insurers, and the address on your website, invoices and email footers (companies must state registered details on business correspondence). The confirmation statement is the annual moment to check it’s all consistent.
