British regs. allow a 4% voltage drop, but that's from the supply terminals at the service entrance to the farthest outlet.
Bearing in mind that at these currents the voltage drop on the house cables is going to be negligible, if we extended this to allow 4% from transformer to point of utilization, it would probably still be within tolerance -- Just!
