How Electricity Apps Can Help Cut Your Power Bill

Thanks to smart apps, it’s never been easier to manage your electricity usage and slash your power bills.

Keeping regular tabs on your electricity usage is the first step to smaller bills. Knowing when and why you’re burning through electricity gives you the insight to cut your bills. And, thanks to smartphones and apps, its never been easier to take control.

Many retailers offer electricity smartphone apps, and consumers prepared to take a proactive approach can reap the benefits.

Gaining an understanding of your patterns of usage can help in choosing the right tariff for your household. These include: fixed-price tariffs, time-of-use and spot-price tariffs. And, once you’re on a suitable plan, an app can help you use electricity in a more cost-effective way.

In this guide, we look at some of the apps on offer:

App features

The rollout of smart meters, which record your electricity usage, has provided real-time insight into electricity consumption. Retailers are harnessing this data to present customers more information about their usage.

Account management and monitoring apps place this information in the palm of your hand. They allow for on-the-go access via smartphones, both Android and iOS. Consumers should look out for the following useful features:

  • Usage – is it possible to monitor your electricity usage and costs in real time? Can usage be broken down over days, weeks and months. Is access provided to past bills and historical data?
  • Notifications – are alerts provided when new bills are issued, or with information about pricing or promotions?
  • Online chat – is there an online chat service provided for customer enquiries?
  • Forecast costs – is there a function that estimates what your costs are likely to be over a period of time?
  • Payment – can bill payments be made within the app?
  • Settings – can you make changes to your account (such as changing billing information)?

When comparing the different power apps, it’s a good idea to read their reviews first. You’ll find consumer feedback on the Google Play and App Store platforms.

Retailer app offerings
