I've put off this quick and easy task in my home for more than a year and it's cost me up to £235 on wasted energy – don't make the same mistake I did!

As someone who writes about saving energy for a living, I like to think I'm pretty good at practising what I preach. But when life gets busy, it's all too easy for measures to reduce my energy bills to get pushed further and further down the to-do list.

While I've rectified the energy-wasting decor mistakes I've been making for years, I know there is always more I could be doing to save energy at home.
