gkenyon:In a house without a metal frame, and with only plastic internal and external service pipes, there is no equipotential bonding.
ADS still operates in the manner I have explained. It relies on the fault current path back through the protective conductor of the circuit concerned, not the equipotential bonding.
Equipotential bonding does not affect the speed of operation of protective devices in ADS (as far as BS 7671 calculations are concerned) - it is used only to control touch voltages for the duration of a fault.
You have forgotten about the radiators!
