UK: the words that turn a ten-minute incorporation into a six-week one
Registering a company in the United Kingdom is normally same-day and almost entirely automated. Put one word from the sensitive list in the name and it stops being automated: the application needs supporting evidence, or a letter from a named body confirming it does not object, before anything is registered.
Not banned. Conditional. The words fall into two groups: those suggesting a connection with government or a public authority, and those implying a status, function or regulated activity that has to be earned. Either way the registry will not simply accept the name — you have to show you are entitled to the impression it creates.
The categories, with examples
| Category | Words like | What is needed |
|---|---|---|
| Government and public authority | Government, Parliament, Council, Commission, Ministry, Authority, Agency | Confirmation of no objection from the relevant department or devolved administration |
| Monarchy and honours | Royal, King, Queen, Prince, Duke, His Majesty, Windsor | Approval from the Cabinet Office or the relevant devolved government |
| Financial services | Bank, Banking, Insurance, Assurance, Reinsurance, Fund, Mutual, Underwriting | Non-objection from the financial regulators, and generally the authorisation those words imply |
| Regulated professions | Chartered, Dental, Dentist, Nurse, Midwife, Optician, Veterinary, Patent | Non-objection from the relevant professional regulator |
| Education and charity | University, Polytechnic, Charity, Charitable, Foundation, Institute | Approval from the relevant department or regulator, usually evidencing the structure claimed |
| National and pre-eminence | British, England, Scotland, Wales, National, International, Group, Holdings | Evidence that the standing implied is justified — size, structure, or geographic reach |
The words founders trip over
Nobody sets out to call a company Ministry of anything. The names that stall are the ordinary-sounding ones.
- Group and Holdings imply a corporate structure. A single company with no subsidiaries using either can be asked to justify it.
- International and Global imply reach across countries, and that impression has to be supportable.
- Institute reads as a research or educational body of recognised standing, which is a higher bar than a consultancy.
- Trust can suggest a regulated or public entity depending on what follows it.
- Foundation suggests charitable status even when nothing else in the name does.
Beyond the sensitive list
Two further constraints apply to every UK name. It cannot be the same as an existing registered name — and “same as” is defined by a rule that strips out punctuation, common suffixes and certain words, so Northwind Ltd and North-Wind Limited can collide. And it must not be offensive or constitute a criminal offence.
Separately, a name that is accepted can still be challenged afterwards by someone with an earlier reputation in it, through an objection procedure that can force a change. Acceptance by the registry settles less than it appears to.
Questions
How long does approval add?
Enough to matter. A clean incorporation is typically same-day; one needing a letter of non-objection depends entirely on how quickly the named body replies, which is measured in weeks rather than hours. If you have a launch date, either avoid the word or start the correspondence well before you need the company.
Can I use a sensitive word as a trading name without it being in the company name?
Business-name rules apply to trading names as well as registered company names, so putting the word on the sign rather than the certificate does not sidestep the restriction. It may also create exactly the misleading impression the rules exist to prevent, which is a separate problem.
The checker flagged a word but it is part of an ordinary English phrase.
The flag is a prompt, not a verdict — it matches on the word wherever it appears, which will sometimes be a false alarm. The published list and its guidance are what decide, and they take context into account in a way a substring match cannot. Read the list before you abandon a name over a flag.
