How to calculate gas and electricity bill from smart meter reading?

A lot of smart meters are able to tell you exactly how much you’re spending on energy per day. They also allow you to set spending limits so you don’t go over budget on your gas and electricity consumption.
If you want to calculate how much you’re spending on energy each month, you can do this fairly easily using your smart meter. You can either estimate your spending by looking at how much you use per day on average and then multiplying it by 30, or you can look at how much energy you’ve consumed since your last bill was issued.
If you go down this route, you’ll need to know how much your energy company charges per kWh of energy you consume. You’ll then need to multiple that amount by the number of kWh you’ve used.

Electricity smart meters

There are a few different types of electricity smart meter installed in UK homes and businesses. Each smart meter works in a slightly different way. Here’s a guide to taking meter readings from some of the most common types of smart meter.

Taking a smart meter reading from your in-home display

As well as a smart meter directly attached to your energy supply, all gas and electricity smart meters come with an in-home display, or IHD. This is a small digital screen that effectively offers you a window into your smart meter. You can use this to get a meter reading instead of going to the smart meter directly.
Not only will your in-home display show your current meter reading, it will also tell you how much money you’re spending on energy every day. This can be very useful if you’re trying to reduce your energy consumption.
Your IHD will update every 10-30 seconds throughout the day. This provides you with a very accurate idea of your energy usage. Getting familiar with your in-home display will help you to get the most out of your smart meter and help make your home as efficient as possible.
