Start by comparing your latest bill with earlier usage to see when and how much electricity you use. Set heating and cooling efficiently, seal draughts, wash clothes in cold water, and use a clothesline where practical. Turn off appliances at the wall when they are not needed, particularly devices that use standby power, and replace older globes with efficient LEDs. Check your retailer’s tariff and available plans, but compare estimated annual costs and conditions because savings depend on your home, usage and provider.
