Was in a house the other day where as far as I could tell there were

Um, that's just one radial circuit.
Shouldn't be a problem unless the loading is silly,
like if it's doing a large kitchen and utility room.

But since this is the normally thoroughly sensible Martin A speaking, he
probably meant precisely that the four main branches of the single
radial were indeed supplying loads/floor-areas considerably in excess
of the reasonable burden on a single 20A circuit (not to mention the
controllability/incovenience factors), and expected us as intelligent
readers to infer this from context...
