Online Energy Tariffs

What’s in this guide?


Did you know that online energy tariffs are usually some of the cheapest on the market?

But what is an online energy tariff?

Is it right for me and my home?

Take a look at this guide, which will tell you everything you need to know about online energy tariffs, including what they are, which cheapest deals are available and if they might be right for you.

What is an online energy tariff?

An online energy tariff, as the name implies, is an energy tariff that you manage entirely via the internet.

Not only do you receive your bills and correspondence online, but you can also log your meter readings via online portals or email as well rather than by the post.

This paperless method usually means it is less expensive than other types, as the company no longer has to spend money on the post.

Although your accounts will be set up and managed online, you can still usually speak to your energy supplier on the phone if you have any problems.

You may want to check if your online tariff has any exit fees for leaving before the contract ends; however it is also important to remember that even with exit fees it may still be less expensive than other tariffs.

Can I save money with an online energy tariff?

Online account management means that companies no longer have to spend money on sending bills and correspondence via the post, or taking manual meter readings.

These savings that the company makes usually come back to you in the form of a decent discount.

If you decide that switching may be the best option for you, you’ll usually find that online-only energy tariffs are less expensive than their competitors.

Online energy tariff cons

✗ You need a device with the internet
✗ Not for those who prefer getting their bills in the post

Is it right for me?

Having constant access to your account regardless of the day or time can be great for many customers. It allows you to have more control and you can instantly access your information.

You can also provide more meter readings. This can then lead to more accurate billing which avoids any nasty bills or backbilling.

Many suppliers will also offer you some extra tools like graphs to gauge your usage. As well as detecting any sudden changes to your energy use.

If you have access to the internet and you’d prefer managing your account online, an online tariff might be a great option.
