Put your thermals on and get rid of the draughts......er, not quite, ed. The second bit is quite right - there are going to be draughtproofing workshops going on at a house near you pretty soon. Your Street Champion coould well be examining your front door as you read this blog... and tut-tutting at the results. Even if your doors have draughtproofing strips already, they may be in poor repair and need replacing.

Thermals? Yes, thermal imaging is the name of the game - using a special heat-sensitive camera, Street Champions will be having a look at their houses to check for weak spots in the insulation or seeing whether any changes they've made have had the desired effect. You can join in and check out your own house, if you want.
