The Small Print Your Company Is Legally Required to Wear

Pick up any tin of baked beans and there it is: a list of ingredients nobody reads until something goes wrong. Your UK limited company has the same thing. A mandatory disclosure label, required by law, that's supposed to appear on every letter, every order form, every website. Most small business owners know it exists in the same vague way they know about the Geneva Convention – it's there, it's serious, they couldn't tell you what any of it actually means.

So let's read the tin.

The Name (Which Is Not Just Your Name)

The first ingredient is your company's registered legal name, and this is already more interesting than it sounds. The name on your Companies House registration is the only one that counts legally. That means "Dave's Brilliant Bakery Ltd" and "Dave's Brilliant Bakery" are two entirely different things in the eyes of the law, and using the wrong one on a contract could, in theory, create a genuine dispute about who actually signed it. The "Ltd" is not decoration. It is load-bearing punctuation.

The Number (A Birthday Card For Bureaucracy)

Your company registration number is an eight-digit code issued by Companies House the moment your company was incorporated. Think of it as a date of birth stamped onto a birth certificate that never yellows or gets shoved into a drawer. Every filing, every change of director, every dormant period – all of it lives under that number, permanently. The reason it has to appear on your letters and website is so anyone dealing with you can pull your full public record in about thirty seconds. Which is elegant, even if almost nobody does it.

The Registered Office (The Address That Matters)

This one confuses people. Your registered office address is not necessarily where you work. It's the official address where legal documents can be served, which is why a lot of small companies use their accountant's address. The rules require you to display this address on all business communications – not your trading address, not your studio, not your house (though it could be). If a court summons or a tax letter needs to find your company, this is where it goes.

The Grey Zone in Your Email Footer

Here's where it gets genuinely odd. The Companies Act 2006, and the regulations underneath it, specify that disclosures must appear on "business letters, order forms, and websites". But the underlying definition of "business letter" traces back to company law written in 1985 – before email existed as a thing anyone had to legislate for. There has never been a definitive, tested ruling on whether a standard business email is legally a business letter or not. Most lawyers say treat it as one, just in case. But nobody has ever been prosecuted for a bare email footer, and the formal guidance is genuinely vague about it.

The practical answer almost everyone lands on: put the full disclosure in your email footer, keep it on your website footer, and sleep soundly. The tin should be readable. That seems like a reasonable place to end up.
