Tax advice. UAE and UK double taxation treaty

I need someone who can advise me on how to maximise my net income in the UAE and UK.

The relevant individual will need to be, I think, an authority on the following agreement between UAE and UK governments:

Some background that you can refer to:

1. I am a UK resident but living in UAE for more than half the year and with an option for obtaining a spousal visa in UAE.
2. I can obtain employment income in both countries
3. I intend to receive directors' fees, employment income and dividends from a UK company which I own.
4. I could open a formal office in the UAE as part of my business growth.

Given this, I believe that any income I earn in UAE will be free of UK taxes. Please advise on this.
