The hall will work because it is often two way lighting on stairs and can be wired with up or down lighting circuits.
A qualified spark such as me would know this so you should ignore the previous two contibutors who are clearly not qualified.
Your problem should be professionally diagnosed because a fire before Xmas is not what you want!
If you are in the Midlands and want it fixed before Xmas call 07747 571292.
