Saving energy at home 

We know that these tips seem obvious, but taking small steps can have a cumulatively large impact on your energy usage and subsequently, bills.

Save energy

  • Only boil as much water as you need in the kettle.
  • Boil water in the kettle and transfer it to a pan instead of boiling it on the hob.
  • Put a lid on your pan to keep speed up your cooking and keep water boiling more easily.
  • Turn off any appliances that you’re not using – including chargers.
  • Use a microwave where possible instead of the oven. 


  • Switch off any lights and lamps you’re not using.
  • Turn off all the lights you can when leaving a room.


  • Close your windows and doors when the heating is on.
  • Shut your windows overnight in winter.
