The process of registering and operating a business in the UK is governed by the government agency named the Companies House. The formation process (for both UK & non-UK resident) will require you to send your application to the Companies House for approval either by post or through a web portal or through an authorized agent.
The registration process does not differentiate between a UK resident (or citizen) from a Non-UK resident. You can be citizen or resident of any country in the world and still register your UK Ltd company. However, there is a very important point to note in this process. Every company formed in the UK requires a registered office address and this cannot be provided by the non-UK resident. That’s why most non-UK residents use a company formation agency to register their UK limited company.

A single person can hold all three positions and he/she can be a citizen/resident of any country and be more than 16 years old. There are no upper limits to the number of directors or shareholders you can nominate, but there should at least be one person.
