English family moving to Bangalore from London

Dear Internations
This is my first post so please bear with me!
We are planning to relocate to Bangalore in August Protected content .
We are hoping to send our young boys to Bishop Cotton Boys School. Where should we live? We live in Fulham in London. I know Bengalore is very different but it must be a bit like London in that there are place you would want to live and other areas that you would avoid. I want to research accommodation options but have no idea where to start!
I would appreciate all advice.
I have heard there are some lovely complexes but that these are out of town and this might not make it so easy for getting the kids to school.
Thanks in advance to anyone who has the time to help me.
