The Benefits of Knowing More

You use the remote to turn off the TV, flick the light switch off, and head to bed. All is quiet in the house, and all your appliances are switched off. Or are they? That silence can be misleading. In most rooms, you probably have at least one device that’s on or on standby, quietly draining electricity – whether you’re aware of it or not!

Around 30% of the electricity used in an average house is wasted. That’s around £250! It can pay off to understand exactly what is contributing to your electricity bill, so you know which changes can ultimately save you money.

What Is a Loop Snoop?

If you want to find out how much each appliance in your home is costing you, go on a Loop Snoop – the name for our hunt which helps you uncover your energy-wasting devices. 

Using your smart meter’s in-home display to get real-time readings, follow the steps below to see the running costs of your things and record them on the Loop Snoop map.

Once you find out how you use electricity in your home, then you can start making smart, energy-saving decisions.

How To Calculate Standby Energy Costs

By following just four steps you can take back control of your energy use and see how much you can save. Before you start, you’ll need to be signed up to Loop. Then you’re ready to go!

1. Find Your Baseline

Find out your home’s baseline energy usage by turning off all your appliances (apart from essential items like your fridge and freezer) so you have the lowest possible ‘background’ energy use in your home.

2. Check Your IHD

Use your smart meter’s in-home display to see live electricity use. You can toggle between £/hr and live electricity consumption in Watts. Make a note of this background energy usage in £/hr.

3. Turn on Appliances

Now go around your home, room by room, turning appliances on and off, one at a time. As you turn each one on, you will see your live £/hr cost change on your smart meter’s in-home display.

4. See Running Costs!

Do some simple maths to reveal the cost of having that appliance turned on for one hour. Record this on your Loop Snoop map here as a reminder to turn stuff off! 

Why Go on a Loop Snoop?

By doing this in each room, you’ll get a good idea of how much your things cost to run. You might find some surprises along the way!

One Loop user said they discovered their coffee machine was sucking power when it wasn’t turned on, so now they always turn it off at the switch. Another found that some of their lights were using eight times more electricity than others, while their old tumble dryer was so inefficient it was contributing nearly a third of their monthly bill.


Loop has helped thousands of users understand their appliance costs and reduce wasted energy.

This app makes it so much easier to track energy usage than my current provider’s app. There is so much useful advice provided by the service, eg ‘phantom load’, which identified where I was wasting fuel. Finally, the Turn Down & Save events really made me think about my usage and showed just how easy it was to reduce it. The Amazon vouchers were a welcome bonus.

Great free app for tracking your electricity usage if on a smart meter. My smart-meter monitor is too far away from the smart meter in my apartment block so I am unable to get readings, and my supplier's app does not supply this, so I was delighted to discover Loop. Loop allows you to see your usage every hour, so it is helpful to monitor what devices use the most electricity and your "phantom load", it is also helpful to have a broader look through the week and month views.

I found Loop to be extremely helpful last winter when energy prices were almost unaffordable. I checked every day and soon got into the habit of turning everything possible off at night to cut down on the phantom load. It taught me to cook in bulk, share a bath, wear more clothes, snuggle under a blanket - anything to avoid turning on the heating. I have recommended Loop to my friends and neighbours and still check regularly to make sure I don't overspend. It's got to be good for the environment - more people should know about it.
