The house I was renting last year had no insulation, no double glazing, no vapor barrier. No fireplace, and a single heatpump. Borer all through the walls, and a hopeless design (rotated the wrong way so the kitchen got no sun) didn't help either. Maybe it's survivors bias, those houses that are 125 years old now tend to be looked after and kept up to date.
