Our top five energy monitor tips

Buying a Best Buy energy monitor won’t slash your electricity bills on its own, but it will highlight where you can save money, and show you the instant impact that your energy-saving actions are having. The actual savings are then down to you. 

Small-scale trials have revealed that you can save anywhere between £25 and £75 from an annual bill of £500, although you could save more. According to a survey of our members in 2014, 72% of our members who own an energy monitor say it has increased their understanding of usage and 48% agree that it has helped them to use less electricity.

Take a look at our guide to cutting your energy costs, and read our top five tips below to get the most from your energy monitor:

1. Choose the best energy monitor for you

While all energy monitors offer similar basic functions, some are much better designed than others to help you take action. You will also want to make sure that the monitor you get has the best usability features for you, so you will need to pick between a static monitor, a monitor with a battery-powered portable display, an online-only monitor that uses your existing smartphone, tablet or laptop as a screen, or a combination of all these features.

In our energy monitor review you can see how more than a dozen different energy monitors scored in a variety of tough tests and see which we rate as Best Buys – these are the top-scoring energy monitors that have proved they can report electricity usage accurately and consistently, as well as presenting the information in a useful way.

2. Investigate your energy usage

Once you’ve chosen and set up your energy monitor, you’ll start getting almost instant feedback on your electricity usage. Take this opportunity to play with your new gadget and investigate your energy use thoroughly.

A good way to discover more about your energy use is to turn off everything you can in your home – this will get the reading on the monitor as low as possible. Then walk through all the rooms in your home and try turning on different appliances, watching the monitor reading increase. Try and make a list of the top ten worst appliances or rooms for energy use in your home.

Some energy monitors make this investigation process easier than others. Ones with display units that take batteries are portable, but mains-powered ones must stay plugged in so you’ll have to re-plug it in every room you want to investigate. You can use our compare features and prices tool to find models with battery-powered display units.

Also, some energy monitors offer quicker feedback than others. How frequently the transmitter sends information to the handheld display varies from around every two seconds to every 12 seconds. See full details of each monitor’s frequency of transmission in our energy monitor review.

3. Change your habits

Once you understand where you’re using a lot of electricity, you can identify areas you can save. This doesn’t mean depriving yourself of the appliances you need – it’s energy wastage rather than simple usage that you want to cut down.

This means watching out for appliances that are being left on unnecessarily, turning things off standby and making sure all your energy-guzzling appliances are working as efficiently as possible.

The biggest savings are likely to be made by cutting down how often you use energy-hungry appliances and how long you use them for - where possible – including electric heaters and electric showers. If you can, you might also want to consider replacing appliances that use a lot of energy with a more energy-efficient version - go to our appliance energy cost calculators to find out just how much common appliances cost to run.

Some light bulbs also use a surprising amount of electricity, so consider replacing them. Do this initially in the rooms you use most often. Take a look at our lightbulb reviews to get the most energy-efficient models.

Some energy monitor instructions give estimates on how much you can save by taking certain actions. You can find plenty of additional advice in our guide on how to use less electricity – including tips on using your washing machine, dishwasher, kettle and fridge efficiently, and details on how much you could save by switching various items off standby. 

It’s true that you don’t need an energy monitor to make any of these changes – but an energy monitor can help you identify which changes will make the biggest difference in your home and will give you almost instant feedback on the effect your changes are having.

4. Get everyone involved

It will be easier to reduce your energy use if you can get your whole household involved in the challenge.

By explaining the energy monitor’s purpose and helping your family (or housemates) understand their energy use, too, they will hopefully be more inclined to reduce their energy wastage.

Most energy monitors are fairly easy to read, so even children can join in – if the usage figure is creeping higher, encourage them to seek out an appliance to turn off.

Some energy monitors allow you to set daily targets for energy usage, and some have high-usage warning alarms – these functions give you something to aim for together.

5. Monitor your energy usage over time

Energy monitors have the potential to be a novelty item that gets neglected once you’ve checked the energy use of all your various appliances. However, they can offer even more useful feedback when used over a long period of time.

The quality of historical data offered by different models varies significantly, but most energy monitors we tested offer some kind of historical information. Take a look at our energy monitor reviews to find out which are best.

You can use this information to spot inconsistencies from day to day, or week to week. If your energy usage was particularly high on a certain day, question why this was. There may be a simple explanation - like you had relatives visiting or a mountain of washing to do. But if not, there could be energy wastage to investigate - and money to be saved on your energy bill.

To fully understand your electricity use patterns it makes sense to keep a note of your weekly or monthly usage. Or, if your energy monitor allows, download this data to your computer.

It’s also important to read your energy meter regularly (at least quarterly) and provide these readings to your energy supplier. This will ensure you are getting accurate bills, which will be easier to compare with the data your energy monitor is providing.
