Couple in an apartment vs Couple in a house: Electricity Use Compared in the UK (2026)
The same two people use noticeably more electricity in a house than in a flat. Not because of the people, but because of what a house comes with: a tumble dryer, a chest freezer, more rooms to light, a garage door, garden tools, and often a home office. Regulators in Germany and Canada publish flat and house figures separately for exactly this reason.
In the UK, couple in an apartment uses about 2,500 kWh a year (£54.17 a month) and couple in a house about 2,500 kWh (£54.17 a month). That is 1.0× as much, or £0.000 more per month. Per person: 1,250 kWh vs 1,250 kWh a year.
