Generally speaking, if you are an executive director, your relationship with the company would be governed by a service agreement and your directorship would be linked to your role as an employee.
If on the other hand, you are strictly a non-executive director, your relationship with the company should be governed by a non-executive director appointment letter. It may also be possible for you to provide separate services to the company as a self-employed individual under a consultancy agreement. Neither a non-executive director nor a genuinely self-employed consultant should be involved in the day to day running and operations of the company.
