So can you set up a limited company focusing on one business and continue to act as a sole trader in another business.
For example, Joe is a soletrader who provides I.T. training. He also wants to start a limited company selling widgets to the bakery industry. Can he be prevented from doing so?
Basically the company is one entity and you as a sole trader is another entity. So be very careful when you are trading to not mix the two business up.
Before forming limited company make sure you definitely need one. May be expensive to wind one up again if you find you no longer need it. Be carefull what you sign when operating as a limited company. Beware of personal guarantees. Educate yourself on the responsibilities and duties of company officers.
