This is easier in newer properties as they're more likely to have been built with efficiency in mind, with double-glazed doors and windows and thermal insulation throughout.

I've put together some of the top tips that I use in my own 1860s home in Scotland -- a building where any improvements I can make to its efficiency go a long way.
