Energy efficiency is dull, but it’s important for climate change and saves pots of money. And once you do it, you don’t have to do it again. Browse a range of environmentally friendly products from solar battery chargers to shower timers at Nigel’s Eco Store (nigelsecostore.com). Alternatively Ecopromotion.co.uk has some good energy (and money) saving tips, such as reflective radiator panels, which are attached to the wall and direct heat back into the room. The site reckons a £25 pack of six will cut heating bills by up to 20 per cent, or £120 a year for the average three-bedroom semi-detached house. In any case, they should at least pay for themselves in a year, after which your home will be warmer, and cheaper to run.
