Renting Part of Home via Limited Company — Best Process?

I recently my own Limited Company. I am a consultant and plan to grow the company into a marketing agency.

I currently work from home and would like to charge a portion of my rent to the Limited company. I rent my home, I do not own it. I understand that a Limited company can 'rent' part of a home for this purpose.

There is mixed information online and I am trying to work out the most tax efficient way to do it. Some information online states that any rental amount I pay myself from the Limited company must be reported on a Self Assessment form each year (I've never done a self-assessment before) and that this amount may be taxable as income. Of course, the full amount would be going to my landlord so there is no profit for me. Can anyone help with best process?
