Repair - Scaffolding issue

Hello the helpful Community,

I need to do some painting works on the windows which locate on the second floor of a conversion flat (it was a house which split into 2 flats).

I assume I would need to hire a scaffolding due to the high restriction. Can some one please help me as to which type should be used, and where can I hire it? I've search on google but can't find what I'm looking for so hope for some rescue from the experienced.
Do I need the council permission to put it up? (I'm a leaseholder of the council)

Many thanks,
