How does the smart meter in-home display work?

Your in-home display works by talking to your meter and giving you constant updates on what you’re using. Your electricity info updates about every 30 seconds and your gas about every 30 minutes. When you switch your smart meter in-home display on, it takes a moment to “find” the meter and start talking to it. It should take less than a minute for your electricity consumption to display – and a couple of minutes for your gas information to show up.
Your in-home display is set to an “average” household, but after a couple of weeks it will learn the average for your home.

Some practical points before you start

Charging your display
It’s best to leave your smart meter display plugged into the mains. It has a built-in rechargeable battery which should last for around four hours if it isn’t plugged in. If the battery does get low, the low battery icon will flash and it takes about three hours to charge.

Find a suitable location
It’s a good idea to keep the in-home display somewhere where you can always see it. This will help you keep an eye on the traffic light system and make you more aware of how and when you're using your energy. Try to keep the display near your actual smart meter to make sure the two are connected. 

Smart meter connection
If the message ‘connecting to smart meter’ is displayed more than one hour after turning it on, move it closer to the electricity/gas meter. If problems continue, call the smart metering team on 0333 009 7000(1).

How to use a smart meter

Your smart meters come with an in-home display that lets you monitor your energy use. You can keep an eye on your in-home display to understand how you're using your energy. 

  1. The traffic light system will glow green when you’re using less energy and red when you’re using more,
  2. You can switch between gas and electricity at the touch of a button, 
  3. Your display will show how much you’re likely to spend on electricity in an hour if you continue using the same electrical items, so you can make adjustments as needed.

Your smart 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 0333 009 7000(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 0333 009 7000 (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 0333 009 7000(1). Lines are open Monday to Friday 8am to 8pm and Saturday 8am to 2pm.
