Limited companies: the requirement
GOV.UK says you must include your company’s name on all company documents, publicity and letters, and that on business letters, order forms and websites you must show:
- the company’s registered number;
- its registered office address;
- where the company is registered (England and Wales, Scotland or Northern Ireland);
- the fact that it’s a limited company (usually by spelling out the full name including “Limited” or “Ltd”).
GOV.UK adds that if you include directors’ names, you must list all of them, and if you show share capital, you must say how much is paid up.
A footer that covers it
Put it in the site footer so it appears on every page, and use exactly the name and number on the Companies House register.
Sole traders and partnerships
The GOV.UK page above covers limited companies. If you’re a sole trader or partnership, it’s still good practice to show your name or trading name, a contact address and contact details, so customers know who they’re dealing with.
Why it also helps customers
People checking a builder often look them up on Companies House. Consumer guidance tells them to: Citizens Advice suggests checking that a trader is genuine and getting full contact details. Clear, matching company details make that check easy and remove a reason to hesitate.
Questions people ask
Do I have to show my registered office address if it’s my home?
GOV.UK says a limited company’s website must show its registered office address. If you don’t want your home address public, you can use a different registered office address, such as an accountant’s or a registered office service, provided it meets Companies House rules.
Is a company number in the footer enough?
The GOV.UK list covers the registered number, registered office, place of registration and limited status. Include all four.
Does this apply to my Facebook page or Google profile?
GOV.UK refers to company documents, publicity, letters, order forms and websites. Including the same details wherever you have space is the safe approach.
