What's the best energy efficiency measure you've taken at home. It may be the one that saved you the most off your heating bills, or the easy, quick fix that blocks off the draught that used to howl around your ankles while you watched TV. Or maybe it's the ingenious bodge job, that didn't cost you a penny.

Whatever you've done we want to hear about it, so that other people can copy it, and stay warm for less this winter too.

To encourage you to share your triumphs with us we're giving away two fabulous Geo Minim energy monitors. They make it easy to see how much energy you're using at a glance, by using a visual representation as well as numbers.

Entering the competition is easy, just add a photo or text onto our facebook page YouGenUK. There will be prizes for the best idea and for the best photo.

But you'll need to do it soon. The competition closes on 30 November.
