In 2013/14 I carried out simple, inexpensive energy efficiency changes to my 1920s home and over a 12 month period reduced my gas usage by 99 per cent (see my bill below). Over the next few months I will be writing about how I did this and how much it cost.

Energy efficiency really is the best solution for reducing energy bills. It is great to see it ‘in action’!
