Do I need my own bank account to apply for a United Kingdom visa?

You need a personal bank account when applying for a UK visitor visa. This account should contain your personal funds, which are separate from your company's funds. You cannot rely on your company account's bank statements because they do not represent money that is only for your use. (The money is the company's; conceivably it would be used for payroll, business expenses, equipment, etc.)

What you should do is as follows:

1. Open a personal bank account.
2. Start drawing a salary/dividends on a regular basis from your company.
3. Deposit this salary into your personal account.
4. Retain your pay slips as a record of your earnings.

After some time, you can apply for the UK visa and submit your personal bank account statements, along with your payslips.

While this seems like a case of just moving money around, it is important to distinguish between yourself as a person, and your employer as a company. Even when you own your company, you are an employee of that company. Your pay slips will serve to prove the provenance of your funds -- where it came from, how you got it, taxes have been paid, etc., and that it is entirely legal.
