Before you can register a limited company in the UK, you must provide a registered office address. This is a legal requirement, not optional — but it does not have to be where you actually work. Understanding what this address is and what it means can save you from a significant privacy headache.
The Legal Definition
A registered office address is the official address of your limited company as recorded at Companies House. It is the address to which all formal and legal correspondence from HMRC, Companies House, and other government bodies will be sent. It appears on the public register, which means anyone can look it up.
Legal Requirements
Your registered office address must meet the following criteria:
- It must be a physical address in the UK (not a PO Box alone)
- It must be in the same country where the company is registered (England/Wales, Scotland, or Northern Ireland)
- It must be an address where mail can be delivered and acknowledged
- It must be kept up to date — you must notify Companies House of any change within 14 days
Why You Should Not Use Your Home Address
While you can use your home address as your registered office, most founders choose not to for these reasons:
- Privacy: The address is on the public register, visible to anyone, including competitors, cold callers, and the general public.
- Professionalism: A home address can undermine the professional impression your limited company projects.
- Practical nuisance: You may receive a significant volume of official correspondence at that address.
- Future flexibility: If you move house, you must update Companies House — which can be easy to forget.
Professional Registered Office Services
Many company formation agents and business address providers offer a registered office service. They receive official mail on your behalf, scan it, and forward it electronically. A London-based prestigious address (such as a central London postcode) can be obtained for a modest annual fee and can significantly enhance your company's professional image.
When you register through Sterling Formations, your registered office address requirements are handled as part of the formation process, giving you a professional UK address from day one.
Changing Your Registered Office
You can change your registered office address at any time by filing form AD01 with Companies House online. The change takes effect immediately once approved, and the new address will appear on the public register within a few days. The new address must be in the same country of registration as the original address.
Registered Office vs. Service Address vs. Trading Address
These three types of address often cause confusion:
- Registered Office: The company's official address with Companies House. Must be a physical UK address.
- Director's Service Address: The address of each director as listed on the public register (can be the same as the registered office — often the preferred choice for privacy).
- Trading Address: Where you actually conduct business. This is not registered anywhere and can be any address, including a home office or co-working space.
Frequently Asked Questions
Can I use a PO Box as my registered office address?
No. Companies House requires a physical address that can receive and acknowledge mail. A PO Box on its own does not satisfy this requirement, though some professional address services use a PO Box with a physical delivery component — check with your provider.
What happens if I use an address where I no longer receive mail?
You risk missing critical legal notices, statutory demands, and court documents, which can lead to serious legal consequences including the company being struck off the register. Always keep your registered office address current.
Can my accountant's office be my registered office address?
Yes, many accountants provide this as a service. It is a practical option as your accountant already handles your company's financial affairs and can deal with any correspondence that arrives.
How much does a professional registered office service cost?
Professional registered office address services typically cost between £30–£150 per year depending on the provider and location. A prestigious central London address commands a premium but can enhance your business image considerably.
