Phantom Load: Understanding your hidden energy costs

You use the remote to turn off the television, 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 and apparent inactivity can be misleading. In most rooms, you probably have at least one home appliance or device that's on or on standby, quietly continuing to drain electricity in the background - whether you’re aware of it or not! 

This is part of what’s known as your ‘Phantom Load’ and if you don’t have a grip on it, you’re needlessly spending money on wasted energy. 

What is Phantom Load?

Phantom Load is the name for the appliances left switched on in your home, adding to your energy bill without you necessarily knowing about it. They can be categorised in three ways.

  1. The things you leave on accidentally.
    Turning devices off at the plug when you’re not using them, like your phone charger, is good practice. But, doing this alone won’t result in the savings that could be gained from a complete understanding of your household’s Phantom Load.
  2. The things you know are on but don't know what they're costing.
    Do you know how much your smart speakers are costing you each day - even when you’re not ‘using’ them? Once you’re armed with this information, you can then make smart decisions about using your things more efficiently.
  3. The things you switch on and forget about.
    Easy-to-forget things, like extra fridges or electric towel rails, can fly under the radar and continue to use energy without you realising. They can be some of the biggest energy-hungry appliances, so hunting them out can result in the biggest savings.

Phantom Load Understanding your hidden energy costs 1

Understanding Phantom Load and what’s contributing towards it is vital if you’re looking to save money on your energy bill. Our research revealed the average household could be wasting £368 on their Phantom Load annually, with this set to increase as energy prices rise. As wasted energy contributes to around a third of an average energy bill, it’s a simple way to make a big impact. 

Dr Steve Buckley, Head of Data Science at Loop, says:

“There’s no doubt that the rising cost of energy bills is scary for consumers, but there are still things people can do to cut rising costs. The cheapest energy is the energy you don’t use after all! Understanding whether your phantom load is low, medium or high is the first step toward reducing it. Using a free app like Loop can help you understand how your household uses energy and empower you to make smart decisions about using less.”

Phantom Load savings

You may already be aware that appliances continue to drain energy, even when left on standby. However, whilst it’s definitely sensible to turn things off rather than leave them on standby, the savings here are relatively small. 

The bigger energy stealers that you need to focus on are the things that are left on all the time, either intentionally or accidentally. You might leave them on because you don’t realise how much they’re costing to run, or accidentally because you’ve just forgotten about them.  

Things that fall into these categories include computers, media servers and set-top boxes, plus easy-to-forget things like underfloor heating, heated towel rails and extra drinks fridges.  

If you’re only going to make one change towards cutting your Phantom Load, these are the appliances that will unlock the biggest savings.

However, some energy-hungry appliances like your fridge and freezer need to stay on all the time. For these things, it’s best to focus on efficiency and running costs to know when it's time to replace them with an upgraded model. An older or less efficient model could easily cost twice or three times as much to run as the most efficient models! 

The cost of leaving appliances on standby

Once you’ve tackled the bigger things, it’s time to mop up the last of the Phantom Load savings by switching off smaller standby appliances in your home. Whilst the savings are more modest, they're still worthwhile.

Top tips to cut your Phantom Load

  1. Try Loop! Before you can reduce your Phantom Load, you need to identify which things are using the most power. Then you’ll be able to see where savings can be made. That’s where Loop can help. If you measure it, you can control it!
  2. Go on a Loop Snoop. Use our map to identify the energy-hungry culprits adding pounds to your bill. The simple rule of thumb is that anything that is hot or cold will be using a lot of energy, probably more than you realised.  
  3. Invest in standby savers and multi-socket extensions. These devices enable you to turn off multiple plugs at once. Upgrade to a smart version and you’ll be able to turn your things off remotely, using your smartphone. 
  4. Involve the whole family. If you simply forget to turn your devices off standby, then make it part of your family’s bedtime routine. If you explain Phantom Load to kids, they may turn out to be eager helpers.
  5. Check to see if your standby devices have an Eco mode. Many set-top boxes can be scheduled to go to sleep every night and you can also adjust the brightness of the lights on many wireless routers.
  6. Change your appliance settings. Have you tried changing the settings on your phone, laptop, PC or Server to make them more energy-efficient?  For laptops and phones, this also helps them to last longer between charges.
