Nearly all electrical appliances can be turned off at the plug without causing any issues. The only appliances which may need to stay on are digital recorders which may need to record/update during the time that you plan to turn the device off. The Energy Saving Trust have worked out that a typical household can save £45+ a year, just by following this simple procedure.
You can also save the same amount by following similar steps in the kitchen. For example setting your washing machine to 30°C will help save money straight away. We recommend you follow these tips and keep a lookout for more energy saving tips in the future.
