Best Energy Supplier Apps in the UK (August 2026)
Fuse Energy takes the top spot this month, scoring highest in our independent evaluation of energy supplier apps.
Overview
Quick summary
This guide ranks energy suppliers based on a composite score that evaluates their smartphone apps and digital features. A well-designed app allows you to manage your account, submit meter readings, and track your energy usage without ever needing to call a support line—an essential feature for households that prefer to handle their bills quickly from their phones.
However, choosing a supplier based solely on its app experience means you might miss out on cheaper unit rates or superior telephone support. The suppliers with the highest app scores do not always offer the lowest annual costs or the most renewable electricity options. Ultimately, you will need to weigh how much you value seamless digital account management against your budget and green energy preferences.

Frequently asked questions
How do I know if an energy supplier has a good app?
A good energy app should let you submit meter readings, view past bills, and track your daily energy use easily. You can check customer reviews on app stores to see if the software crashes often or if it is easy to navigate.
Can I manage my energy account without a smartphone?
Yes, most suppliers let you manage your account through a web browser on a computer or by calling their customer support team. However, some newer suppliers are app-only, meaning you must have a smartphone to sign up and manage your bills.
Do variable and tracker tariffs have exit fees?
Some variable and tracker tariffs have exit fees, while others do not. You should always check the terms of the specific tariff before you switch to see if there is a penalty for leaving early.
Will a fixed tariff keep my energy bills exactly the same?
No. A fixed tariff locks in your unit rates and daily standing charge for the length of the contract, but your total bill will still go up or down depending on how much gas and electricity you actually use.
Is it worth paying more for a supplier with a better app?
This depends on how you prefer to interact with your supplier. If you want to handle everything quickly from your phone without waiting on hold, paying slightly more for a highly rated app might make sense. If you rarely check your account, you might prefer to choose a cheaper tariff instead.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
