Exactly Brian! The house I spent the first thirteen years of my life in had exactly one power point. This operated the radio, after we moved up from a crystal set in 1944 or 45, and got a double adapter for the refrigerator when we got one (first in the street I believe) in about 1950. The iron worked from a double adapter in the light socket above the kitchen table, which was used as an ironing board.
The wood stove was replaced by an electric stove in about 1951, but there was only one power point until we built the new house in the mid fifties. It had a power point in every room, I think.
The old house had no heating until about 1950, when it got a wood heater, and there was, of course, no airconditioning. And no insulation. (Had a few other minor issues - for example the need to strategically place buckets whenever it rained! This was the result of it having been built in the 1920s using second hand iron, with a number of redundant nail holes, combined with a very low pitched roof.)
