Do I have to give months notice?

[#1]

Hi, I want to move from Metronet to PlusNet. I've read how to do this, but no mention was made about the months notice required by Metronet. Is it waived because the move is inter company?  Thank you.

You don't need to give notice. 
When I did this for my mother in law it was all completed in less than 24hours.
