How to choose a company name that gets approved
- Check the register first: names identical or very close to an existing company are refused.
- Avoid regulated words such as Bank, Insurance, Capital or Trust unless you hold the licence.
- In the Gulf, avoid religious, royal or government terms and place names such as Dubai or Emirates.
- In the UK, sensitive words such as British, Royal, Charity or Institute need prior approval.
- Secure the .com and the country domain on the same day you reserve the name.
