What is a business? What is a company?
There are multiple types of “business”. These businesses all have in common that they trade - that is, they sell goods and/or services. We often use the word “business” interchangeably with “company”, but a company is just one type of business. Other types of business include “sole traders” and “partnerships”. (Everything I’m writing here is specific to UK law.)
Different business types are registered with different bodies. Companies are registered with Companies House. Sole traders are registered with Her Majesty’s Revenue and Customs (HMRC). Partnerships are also registered with HMRC.
The special thing about companies is that they are legally similar to people. A limited company is classed as a “legal person”. For example, the partners in a partnership are usually people, but since companies are legal persons, companies can be partners in a partnership too.
Companies are not flesh-and-blood people. They don’t have brains or hands or bowel troubles. Companies do things because there are flesh-and-blood people related to that company. The company has directors, an optional secretary, and shareholders.
Guidance says that “Another company can be a director, but at least one of your company’s directors must be a person.” By “person” here, they presumably mean “real, flesh-and-blood, non-company person”. This inheritance relationship

Because a company is a person, its finances are like those of a person: the company can pay, be paid, and make profit. It can own things and owe things.
Because a company is not its directors or shareholders, those directors and shareholders are not liable for things that the company is liable for. If the company is sued, the directors are not being sued. If the company has debt, this is not the debt of the directors.
