How your smart meter helps you

Your smart meter measures how much energy you’re using and sends us regular readings. Your monitor will show you:

  • How much energy you used in real time
  • Your energy history and how much energy you’ve used over the last week, month or year
  • Current tariff information, so you can stay in control

How to use your smart meter

Smart meters replace your existing gas and electricity meters. In most instances they’ll be installed in the same location. What’s great about smart meters is that they come with a handy little monitor called the ‘in-home display’. They’re not compulsory, but if you choose to have one you’ll be able to see how much energy you’re using in real time and throughout the day. You can view your energy history, helping you reduce your energy use and compare weeks or months. To make sure you’re getting the most out of your in-home smart meter display we’ve created some simple guides.

Your questions answered

Why are the price figures on my smart meter display not the same as on my bill?

The figures on your smart meter in-home display will differ slightly from the bill as they include VAT, whereas your bill shows VAT in a separate section. The energy costs on your smart meter display also take into account the daily standing charge.

Why is my smart meter display showing electricity information but not gas?

If your meters have been installed in the last week please wait a couple more days as it can take longer for the gas to update for the first time. If it’s been more than a week give us a call on 0800 015 8787 (1). Lines are open Monday to Friday 8am to 8pm and Saturday 8am to 2pm.

Why is my smart meter display saying I'm using gas when I'm not?

Your standing charge (what’s a standing charge?) shows on your smart meter in-home display each day whether you’re  using energy or not.The daily standing charge for the previous day is added at midnight for an Aclara meter. For an Itron meter it’s added for the current day just after midnight.

If I press the wrong buttons on my smart meter display will I alter the prices?

 No. Your prices should remain unaffected if you press a different button from the one you meant to press. 

Why is my smart meter display showing the old prices when I've changed my tariff?

It can take up to ten working days for your new prices to be loaded onto your smart meter in-home display. If the prices still don’t show after that time, give us a call on 0800 015 8787 (1). Lines are open Monday to Friday 8am to 8pm and Saturday 8am to 2pm.

Do I have to leave my smart meter display plugged in?

Yes, your smart meter in-home display isn’t designed to be portable.  It needs to be plugged into the mains to run.  The supplied rechargeable batteries are for short periods when no mains power is available, for example when moving the device from one plug socket to another.

I haven’t got a smart meter in-home display, how do I get one?

Get in touch and we’ll arrange an appointment for you to have one installed. Give us a call on 0800 015 8787 (1). Lines are open Monday to Friday 8am to 8pm and Saturday 8am to 2pm.
