Do you know how much your appliances cost to run?

If you measure it, you can control it.  Simply seeing how much your electricity is costing you has an impact on how much you use. It’s called the “Feedback Effect” and leads to easy savings through changed behaviour.  Some households could save hundreds of pounds, so it’s well worth getting clued up!

Follow the steps below to take back control of your energy use and see how much you can save.

Got a smart meter?  You can get all of Loop’s energy-saving benefits for free – find out more here.  You can do your Loop Snoop as described below using your smart meter’s in-home display to give you real-time readings.

Step 1

Print out the Loop Snoop map. No printer? No problem! You can also add your costs to the interactive PDF text boxes.

Step 2

Turn off all your appliances (apart from your fridge, freezer and broadband router!) so you have the lowest possible energy use in your home.

Step 3

Open the Loop app or, if you have a smart meter, fetch your in-home display.

Step 4

Write down each cost and see how much individual appliances are costing you to run. On your Dashboard you will see a cost in £ and pence per hour. Note the “resting” level and then go around your home, room by room turning each appliance on and off, one at a time. As you turn each one on you will see your Live Usage figure in the app or on your smart meter’s in-home display jump a few seconds later. Do some simple maths to then see the cost of having that appliance turned on for 1 hour.


  • After turning everything possible off in your house your “resting” usage is at £0.10 per hour. You turn on your kitchen lights – these comprise multiple halogen spotlights and your usage jumps to £0.20 per hour. Then turn them off again ready for the next appliance test. Instantly you know the cost of leaving those lights on for just an extra hour per day is 10p– it doesn’t sound like much but that adds up to over £35 per year!

Doing this in each room will give you a pretty good indication of what things cost to run.  However it’s worth remembering that some high-powered items like ovens, fridges, freezers  and immersion heaters are thermostatically controlled.  This means they draw a lot of power when they’re on, but they aren’t on permanently, only when they need to heat or cool to the required temperature.

Loop user: “It was a real eye-opener on how some lights for example were consuming eight times the electricity than others for equivalent brightness, and also that our old tumble dryer was so inefficient it was contributing nearly a third of our monthly bill!”

Loop user: “By looking at the power being used and turning off an individual appliance I can see how much it uses on standby. Using that method I worked out the coffee machine was sucking power when it wasn’t turned on – now it gets turned off at the wall switch!”
