What is different about a four-person household

Four people use around 6,960 kWh a year between them. That works out at about 1,740 kWh each, considerably less per person than the roughly 3,100 kWh benchmark for someone living alone. The five-or-more group is not an exact household size, so it cannot support a precise per-person comparison.

Season still makes a substantial difference at this household size. Compare your bill against the same season last year, not just against the bill immediately before it.
