Check If Your Company Name Is Available and Appropriate (Avoid Sensitive Words and Expressions)

Your desired company name should be approved by companies house before you can use it. Fortunately, Companies House has naming guidelines that are easy to follow and not overly restrictive, ensuring a smooth name search process as you look for the perfect trading name.

Below find five primary companies' house name check rules for your information.

1. A name must not be identical or too similar to an existing company name.

A new company name must be unique and distinguishable. You are not allowed to register your company with a name that is identical or too similar to an existing registered name. Differences in punctuation, special characters, or commonly used words (such as "Company," "Services," or "UK") are not considered sufficient to make a name unique and different from one that is already registered.

For instance, let’s say you are in the energy sector. You cannot register a company by using the words Shell and adding a word such as “UK” to distinguish your company from the multinational energy company Shell.

It implies that PureGym prioritises the essential aspects of fitness training, offering its members an uncluttered, straightforward experience. The name appeals to prospects looking for a no-nonsense approach to fitness without unnecessary distractions or complications. Combining "Pure" and "Gym" create a corporate image that suggests a commitment to delivering a streamlined, effective, and affordable fitness experience.

The simplicity of the company name PureGym also contributes to its memorability. A short and easy-to-remember name helps prospects recall the business when considering joining a gym or recommending one to others.

Companies House check name lessons from MoneySuperMarket and PureGym

Lessons we get from PureGym and MoneySupermarket in crafting memorable registered company names are as follows:

1. Use Keywords in your business name.

The simplest way to resonate with your target audience as you communicate the value of your business is by using keywords. If you use a keyword in your name, research your industry's most popular, relevant and competitive words and terminologies.

companies house name check

To get the best keywords for your business name, you only need to identify the language and words your prospects use when talking or searching about a business in your area. To get these words, you may review the questions and comments on social media platforms such as Facebook community groups, Reddit, Quora and Twitter.

However, remember, language and word choices are bound to evolve and change with time. Therefore, you can commit to reviewing your business strategy, which includes your company name, preferably after five years. Regular strategy reviews enable you to remain relevant and in tune with current trends, customer preferences, and industry developments.

2. Make it simple and unique.

A simple and unique limited company name check is essential in distinguishing your business from competitors. Choosing a name that is easy to remember and pronounce increases the chances of your target audience recalling your company when ready to make a purchase decision.

Keeping it simple also makes your business more recognisable, leading to better customer engagement. You also want your name to be unique to prevent confusion with other companies and avoid infringement lawsuits.

3. Consider combining two or three words.

Merging words related to your business can yield a descriptive and unique name that is memorable and indicative of your company's purpose. Successful companies like Microsoft, Pinterest, and Snapchat have used this strategy to create names by combining relevant words. For instance, Microsoft blends "microcomputer" and "software," Pinterest merges "pin" and "interest," and Snapchat combines "snap" and "chat."

What words cannot be used in a company name?

In many jurisdictions, including the UK, certain words and expressions are restricted or prohibited from being used in a company name without prior approval. These restrictions are in place to prevent misuse that could suggest a connection with the UK government, local authorities, or other regulated or sensitive sectors when no such connection exists. Some examples of restricted words include —

  • Using words like "Bank," "Banc," "Banking," or "Banker," might give the impression that your company is engaged in banking activities, so you'll need approval from the Prudential Regulation Authority.

  • Including terms like "Charity," "Charitable," or "Charity Commission" can suggest your company is a charity or linked to the Charity Commission. In that case, you'll need permission from the Charity Commission for England and Wales or the Office of the Scottish Charity Regulator for Scottish companies.

  • Avoid words like "Government," “,” "Parliament," "Crown," "Royal," or "Regulatory," which imply a connection with or endorsement from the government.

  • Suppose you want to use "University," "Institute," "Academy," or "School," names which may suggest that your company is involved in education. In that case, you'll need permission from the Department for Education or other relevant education authorities.

  • Finally, terms such as "Health," "Medical," "Dental," "Pharmacy," or "Optician" might suggest that your company is engaged in regulated healthcare services. In that case, you'll need permission from the relevant health authorities.

Can I be exempt from using ‘Limited’ or ‘LTD’ in a trading name?

According to section 60 of the Companies Act 2006, companies can omit the word limited or ltd from their name. You can apply for exemption if —-

  • A company limited by guarantee must distribute profits to members and only have charitable objectives.

  • The company require its income to be applied to promoting its objectives.

  • Your members contribute their company assets if it is wound up while they are members or within one year of ceasing to be members.

If your company meets these criteria, you can apply for an exemption from using 'Limited' or 'Ltd' in your company name. You must include a statement of your company's charitable objectives in its articles of association and ensure that the other requirements are met.

For other forms of company structures, the following ending rules must apply -

  • A public corporation must conclude its name with 'public limited company' or 'p.l.c.'. However, if the registered office is declared in Wales (a 'Welsh' company), the name may alternatively conclude with 'Cwmni Cyfyngedig Cyhoeddus' or 'CCC'.

  • Specific phrases and abbreviations that denote a particular type of company (including Welsh equivalents) can only be utilised at the end of a name, such as 'Limited Liability Partnership' or 'Community Interest Company.'
