Most people might assume that flats are warmer than houses. After all, every flat has at least one other dwelling above or below it, making it a lot more difficult for heat to escape. And flats tend to be newer than houses, with more modern construction, glazing and insulation features.
And across the English housing stock the average energy efficiency of a flat is indeed higher than that of a house. But that fact masks the problem that we’re not improving our older flats with energy efficiency upgrades at the same rate as we are our houses.
