Many people have asked me about setting up a company for their new ideas. Setting up a new UK registered company is straight forward and cheap now, due to many on-line incorporation agents. A standard private limited company, which is what most people require,should cost you no more than £30 to £50 in total. You will need one person to be a Director and I suggest you only issue one £1 share to start with. I recommend you go to Company Formation, as they have good first time packages and can provide a solid service for all the required administration. If you are based overseas or not a UK national, Company Formation has tailored packages for that too, as well as help in setting up a company bank account.
