As a London-based formation agent, we are often asked how to reserve a company name in the United Kingdom. The essential point is simple: the only reliable way to reserve a company name is to register a limited company with Companies House. Incorporation prevents others from registering an identical or “too like” name and, if needed, allows you to keep the company dormant. Before you apply, you must check availability and confirm that the name complies with Companies House rules and wider legal requirements.
- Incorporate a company to reserve a company name; the UK lacks a standalone name reservation system.
- Names deemed “same as” can be blocked; consider punctuation, case, and specific terms in this regard.
- Sensitive words need prior consent; offensive names are outright rejected by Companies House.
- Register your company online; this typically completes within 3 to 24 hours under a formation agent.
- Distinctiveness is essential; avoid generic terms for uniqueness and ensure it aligns with trademark strategy.
- Remember annual filings for dormant companies; neglecting this can lead to penalties and strike-off.
What “Reserve a Company Name” Means in Law
The UK has no standalone “name reservation” system for companies. To reserve a company name, you must incorporate a company and have it appear on the Companies House register. This protection arises under the company names regime in Part 5 of the Companies Act 2006 and the related “same as” and “too like” tests used by Companies House. In practice, names that are indistinguishable after disregarding punctuation, special characters, case, the word “Limited”/“Ltd”, or certain generic terms can be treated as the “same as”.
Sensitive or restricted words require prior consent (for example, “Bank”, “Association”, “Royal”, “Accredited”). Companies House can direct a change if a newly registered name is “too like” an existing one, and will reject any name that is offensive or implies a criminal connection. A private company’s name must usually end with “Limited” or “Ltd” (or Welsh equivalents), unless a specific statutory exemption applies. For more details, see our guidance on using company names.
A brief example illustrates the rules. If “Green River Ltd” exists, “Green Rivers Limited” or “Green-River Ltd” will almost certainly be treated as the “same as” and refused. By contrast, “Green River Projects Ltd” may pass only if “Projects” adds genuine distinctiveness and does not fall within the set of words Companies House disregards. We recommend treating distinctiveness as essential rather than optional.
Steps to Register and Secure Your Name
Follow these steps to register and thereby reserve a company name:
- Use our online company name checker to check availability and detect “same as” risks.
- Check for UK trade marks that could block use of the name in commerce.
- Prepare your incorporation details: registered office in the UK, directors, shareholders, Persons with Significant Control, SIC code(s), and share structure.
- Choose the best company formation route: our basic formation package is the cheapest way to register and protect a UK company name; you can also compare our company formation packages.
You can incorporate online, usually via a formation agent, with a standard digital filing that typically completes in 3 to 24 hours. Once approved, the company name is secured on the public register. If you are reserving the name ahead of trading, you may keep the company dormant. Dormant private companies must still file annual accounts (normally within 9 months of the accounting reference date) and a confirmation statement every 12 months; failure attracts penalties and possible strike-off. For a practical walkthrough of the registration process and documents, see our detailed guide on how to register a company name.
Practical legal tips. Choose a distinctive core (for example, a coined word) and avoid relying on generic terms such as “Services”, “UK”, or “Holdings” for uniqueness. Consider future brand and trade mark strategy before filing. If your planned name contains a potentially sensitive expression, obtain supporting consent or evidence (for example, regulator approval) before you submit the application, to avoid rejection and delay.
Conclusion
To reserve a company name in the UK, you must register a limited company. That step, not a separate reservation system, prevents others from taking your chosen name and gives you control over its future use.
If you plan to incorporate now and trade later, factor in dormant filing duties from day one. Checking distinctiveness, legal restrictions and timeframes in advance will protect your brand and save both time and cost.
