Electricity Bill Calculator – UK

We’ve created this electricity bill calculator to help you estimate how much you should be expecting to pay for your electricity over any set period of time.

This may be because you are moving home and want to work out how much more or less you may have to pay, or maybe you are looking to switch tariffs and see how much you could save. Whatever your reason, keep reading to see how to use our free calculator and find out what you need to know.

How to use our electricity bill calculator

You need to start by looking deciding how many days you want to look at, one day, one week, one year or anything in between.

Next, the calculator needs to know your electricity consumption per day. This can be worked out from your latest electricity bill, or you can use our average estimates below.

The next two pieces of information you will need to get from your bill. This will differ depending on your energy supplier and tariff. Your unit rate is how much you pay for each unit of electricity, your standing charge is a fixed amount you pay per day regardless of how much energy is used.

Once you put all these details in, you will automatically see a breakdown of your total unit charge over the period you set, the total cost of your standing charge and what your overall bill would be for that period of time.

Hi, I'm Rob and I run Energy-Review.co.uk. I initially started this project 5 years ago 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 spent have 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.

If you're a customer of this supplier, you can leave your own review below.
