How is your heating powered and hot water heated? Those make up over 50% of most household's bills so they're the best things to cut down on, remember electricity is a lot more expensive than gas so if you're not dual fuel you pay a lot more.
After you've reduced heating (layers, oodies, blankets, heated throws, electric blankets in beds, hot water bottles, thick curtains, fix draughts, increase insulation) and hot water (eliminate or cut down on baths, save up dishes and heat water for less time, turn down water temperature, 2-5 min showers, shave at the sink or turn off shower water during) then you can think about other items within the home.
Make sure all your bulbs are low energy ones (these use 10% of the power of incandescent) but once they are don't worry about using them, led bulbs are very cheap to run, much cheaper than buying candles for instance which a lot of people aren't aware of so don't sit in the dark.
In general things which heat up use the most electricity so it's usually not your telly or laptop or phone charging that's draining the power but your hot tub or vivarium or tropical fish tank or tumble dryer that are more likely culprits.
