A First Utility guide to saving energy – room by room

We’ve compiled a list of some lesser-known ways to save energy around the home simply by making small changes.


  • Towel dry your hair thoroughly to reduce the length of time you need to use a hair dryer
  • Don’t leave your mobile phone on charge overnight – it only needs a couple of hours
  • Set the heating to switch off a short while before going to bed and to come on just long enough for the house to feel warm when you wake up
  • Use the right tog duvet (light in summer, heavy in winter) and opt for a hot water bottle instead of an electric blanket
  • Keep the heat in your bedroom using draught excluders

Living room

  • Replace traditional light bulbs with energy saving compact fluorescent (CFL) bulbs, which use just one third of the energy used by traditional bulbs
  • Don’t leave televisions, computers or other devices on standby. Households waste £227m a year by leaving appliances on standby, according to USwitch.
  • Consider investing in an intelligent mains controller, which will turn all devices off at once
  • Draw curtains at dusk to keep heat inside


  • Don’t half fill the washing machine and only use appliances when necessary. Use a clothes horse or hang washing out on a line as often as possible
  • Only boil as much water in the kettle as you need
  • Consider investing in a slow cooker – it uses just a little more energy than a traditional light bulb and encourages you to plan your meals in advance
  • When you can, opt to use the microwave instead of the oven. Alternatively, a halogen oven uses 75% less energy than a conventional electric oven and can roast a chicken in just 30 minutes.
  • Turn off the hob or oven just before your food has finished cooking because the heat will be retained


  • A running tap wastes more than 6 litres of water a minute and if its hot water then you’ll be wasting energy too. Don’t leave the tap running when you’re brushing your teeth or shaving
  • Choose the shower instead of the bath. Better still, install a slow-flow shower head regulator to save water without making a difference to how the power feels to you.
  • About 30% of all water used in the home every day is flushed down the toilet. Consider getting a water saving device fitted to the cistern of your toilet to use 50% less water with every flush
