If you're thinking about starting a business, one of the first things to do is find the right name. But can you actually reserve a company name in the UK before you're ready to trade? 

The short answer is: not exactly. There’s no formal system to “reserve” a company name in the UK, but you can register your desired company name to prevent others using something too similar. 

What you need to know about registering company names

To protect your business name, you’ll need to incorporate a Limited company with Companies House. This makes your company name official and links it directly to your business.

We’d recommend reading our full guide ‘How to incorporate a Limited company’, it includes the steps involved and what you’ll need to provide.

If you’re ready to take the next step, our company formation service makes it easy to get your business registered and set up in no time.

Considerations before registering

Before you jump in, there are a few things to check before ‘reserving’ a company name:

1. Is the name unique?

Companies House won’t allow names that are identical or too similar to existing company names. Use their name checker tool to be sure.

2. Is it already trademarked?

Even if your name is available at Companies House, it could still be protected by a trade mark. Search the IPO trade mark register to make sure it’s clear.

3. Are the domain and social handles available?

It’s worth checking if you can secure the matching website domain and social usernames. Even if you’re not ready to use them, it's a good idea to lock them in early.

4. What do you need to register a company name?

You’ll need a company structure (e.g. private Limited company or public Limited company), a registered office address, and at least one director. You’ll also need to decide on your SIC code (business activity), and pay a small registration fee.

What if I’m not ready to launch or trade?

If you want to secure your company name but aren’t quite ready to start trading, you might want to consider incorporating a Limited company and then making it a dormant company. This means the company is legally registered, but isn’t currently doing business or earning income.

This can be a good option if you’re still developing your product, waiting for funding, or planning a future launch. We’d recommend checking out our ‘Dormant company’ guide to learn more about whether or not it’s the right option for you. 

Protect your name, protect your idea

While you can’t reserve a company name in the UK without actually registering it, there are steps you can take to make sure your name is available—and protected. A bit of early research can save you hassle (and legal issues) down the line.

If you're serious about starting your business, registering the company is a simple way to lock in your name and give your idea a proper home.

Your responsibilities as a Limited company

Once your company is registered, you’ll also take on some new responsibilities, especially around accounting and tax. Running a Limited company means you'll need to keep proper financial records and to file any necessary tax filings. 

It might sound like a lot, but with the right support (and the right software), it doesn’t have to be a headache. Our Limited company accounting services can help you manage everything, so you can focus on growing your business without the stress of numbers.
