When they go, change your bulbs to LEDs and switch them off when you leave the room (dad was right!)
Use a smart thermostat to control your heating (lowering it by 1°C can feel like a minimal chance but can make a real difference)
Make changes to prevent heat from escaping from your home. From insulating your roof, installing double glazing, to drawing curtains at night, and making sure radiators aren't blocked by furniture
Switch off devices on 'standby mode' and unplug changers that are not in use
Load test: Turn all of your appliances off and make a note of how much energy is costing you per hour (on your fancy new in-home display). Turn on an appliance and see what that number changes to. This is what that appliance costs per hour to run. Older appliance can be replaced with energy-efficient options, when their time comes
Don't over fill your kettle - only boil what you will use
