Not really, the U.K. has some of the oldest housing stock in the world. For e.g. my house is pretty typical, built in 1912, it has a double skin wall of bricks but with no cavity. It has three original fireplaces which are all very draughty. I have timber sash windows, and though I recently got double glazing my neighbours on either side do not have it.
