I have created two UK limited within a 10 year interval without putting my feet there. I recommend you not to do it alone but find a local accountant in UK + an accountant in your country who knows a bit about the UK + your country rules. It is extremely easy to create a UK company, but this creates both obligations in UK and in your country of origin. For example, in Germany, if you are the director of a UK limited, you cannot get "family" health insurance, so you need to have another job or be employed by your UK limited or go private for your health insurance.

So, take the time to see how it affects your situation in your home country.

Note: It will cost you money in all the cases, it is not something you do "just for fun" or you are going to have problems. Setting up a business is work and must be prepared thoroughly.
