Removing 1 window and installing 2 in its place

HI, i am unsure of who can answer my question but here goes. We are looking at removing the 1 window in our bedroom and replacing it with 2 smaller windows to enable us to split the room giving each room its own window. Does anyone know whether this will require planning permission and what the approximate costs would be?

"Hi
This is possible
Is either of the new windows looking towards your neighbours property ?
Hard go say a cost without seeing your property but £4400 to £7000 would be a fair guess
The work would need to be fensa registered or under building control
Hope that helps"
