...what's not permitted?
To have a single point of failure . As your friend has probably found, any fault will trip the supply to the whole place.
Why is a bad idea? Consider this:
You are 79 years old. The time is 9.30 p.m. It is December, it's dark and the weather is cold. You come from the bathroom on the first floor, just on top of the stairs. The thermostat of the central heating comes on, a neutral to earth fault on the pump trips the 30mA residual current device that has been provided as the main switch on the distribution board and all supply is lost in the home. No lights. What happens next....
