one of the advantages of being ltd is that if it goes tits up, all debts are limited to the company and you dont lose your house,
but a lot of banks want director guarantees for loans, so u still got to pay them back
u need a company secretary and a director, one advantage is if you employ people and get a speeding ticket, that doesnt identify driver, get secretary to say dont know who was driving van, and get fine and no points
if you are a director of the company, and pay your self, u have to fill out a tax return for you as well as company
every one i know who has gone ltd says it was a waste of time and more hassle
