How to Read Your Smart Meter

British Gas

Gas reading

The screen will probably be off. Press the red button to wake it up.

Once it says Credit On you can press the red button again.

The screen will say Meter Index. That’s your meter reading.

Electricity reading

If your meter has two barcodes on it, take a meter reading using these steps:

Tap the green A button 3 or 4 times to go through the options.

Keep scrolling through options until the meter reading display screen shows “Rate 01 Act Imp”. This shows your meter reading. If you have a time of use/two rate tariff , press the button again for “Rate 02 Act Imp” for the second rate reading.

If you go too far, keep pressing the button. It’ll loop back around.

If your meter has three barcodes on it, take a meter reading using these steps:

Press green A button twice and then hold down to get to menus.

Keep scrolling through options until the meter reading display screen shows “Total Act Import”. This shows your meter reading. If you have a time of use/two rate tariff, press the button again for “Total Act Import 2” for the second rate reading.

If you go too far, keep pressing the button. It’ll loop back around.


Gas reading

For gas smart meters, press and hold the red button A for five-to-10 seconds. This will then display ‘Credit ON’. Press and release button A, and the meter will display the reading.

Electricity reading

On an electricity single rate smart meter, the display will automatically show the reading.

If you have an electricity multi-rate smart meter, press and release the blue display button and this will show rate two. To find out if you have a multi rate meter, look at your latest bill. You’ll be able to see if there are different charges for the day and night usage.

Geo Trio smart meter in-home display

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 in-home display on, it takes a moment to “find” the meter and start talking to it. Your in-home display is set to an “average” household, but after a couple of weeks it will learn the average for your home. Your bill shows vat and standing charges separately, while the in-home includes these in the energy costs displayed.

A Home Use this touch control to cancel what you’re doing and go to the home screen. B Now Shows what you’re using right now. C Fuel If you’re tracking electricity and gas, the home screen shows you both combined. If you want to see this individually, tap on the fuel button. One tap for electricity, two for gas, three to show you both together. D Calendar Use this to check what you used today – or so far this week, month or year. Tap once for a view of this week, twice for this month – and three times for this year. If you want to see what you’ve used in previous weeks or months, use the arrow keys as well. E Menu/OK Tap OK, then use arrows to scroll through your account information, meter readings, settings and to set your budget. F Forward and back. Use the arrows to scroll through options or information on the screen. On the home screen, you can use the arrows to move between days to see your usage over the last week.

Gas meters

To take the reading from your gas meter, you’ll need to press a button to wake up the meter. Depending on your meter, it’ll be either an OK button, a red “A” button or a round button between two arrowed buttons. The reading will appear on the screen. As your gas meter is powered by a battery, the screen will go blank after a short while to save power.

Electricity meters

On most electricity smart meters, the screen will show your meter reading as standard. If you see a row of zeros, wait six to ten seconds for the screen to show your meter reading. On some meters, you may need to press the OK button or button A to show your reading.


Standard smart meter

Have a look at the display panel on your Smart meter, normally it’ll be blank. Press button ‘A’ or ‘B’ to wake the screen up. Press button ‘A’ again to show the meter reading and make a note of the numbers including any zeros. There’s no need to note down any number(s) after the decimal point.
If you have a single rate meter: Always read the ‘R1’ register and simply write down the numbers from left to right.

Economy 7 smart meter

If you have a two-rate meter: You’ll only need to read the ‘R1’ and ‘R2’ registers. Press button ‘A’ to cycle through the readings and write down each one as it appears.
If it’s peak time when you read the meter, the active register shows your Day/Normal rate reading. If it’s off peak the meter will show your Night/Low rate reading. You’ll notice that one of the registers has “Now” in the top right hand corner of the display. This shows your active register.

For more information see this guide:


  1. If you have a Feed-In Tariff, these symbols show whether you’re currently importing or exporting electricity.
  2. This tells you whether your energy is ON, OFF or READY. The plug symbol refers to your electricity, and the flame is gas. In this illustration, the plug is black while the flame is grey, so the information refers to electricity. If your screen shows OFF or READY, your meter is off supply – so you need to wake it up and get it back on supply. To do that, simply press any button.
  3. If you’ve got unread messages from us on your smart meter, this symbol will be lit.
  4. This tells you which unit of energy you’re looking at. M³ (cubic metres) is gas and kWH (kilowatt hours) is electricity.
  5. HAN stands for Home Area Network. This is the network that smart meters use to communicate with each other, and with your IHD. The symbol on the screen shows that the meter has been set up to provide a HAN, although it may not be communicating with other devices if it hasn’t yet been linked to them.
  6. These shapes become letters or numbers on active meters. They either show messages or amounts, such as how much energy you’ve used, or how much credit you’ve got.
  7. To take a reading, press ‘9’ on your smart meter keypad. This will show the meter reading in kilowatt hours (kWh) for electricity, and cubic meters for gas.
  8. If your smart electricity meter is on an Economy 7 tariff (where you pay a standard price during the day and a lower rate for 7 hours overnight), press ‘6’, then press three more times until you can see ‘IMP R01’. This shows your off-peak (night-time) reading in kWh. Press ‘6’ again and you’ll see ‘IMP R02’. This gives your daytime reading.
  9. We’re asking anyone who doesn’t have a smart meter to submit their readings through their online account or in the OVO app. This is because we’re now only able to take emergency calls, so we can help those who need us most. It’s really easy to submit readings this way – and we thank you for your support.


Standard electricity tariff

  1. Press 9 on the keypad.
  2. You’ll see the letters “IMP R01” appear on the screen.
  3. Wait a moment – then eight digits will appear, followed by “kWh” towards the bottom right of the screen.
  4. Take the first 7 digits – this is your reading.
  5. To take a meter reading on an Economy 7 electricity tariff:
  6. Press 6 on the keypad four times.
  7. Wait a moment – your day/peak and night/ off-peak readings will show up on the screen one after the other, starting with off-peak.
  8. For your off-peak reading, you’ll see “IMP R01” onscreen. A second later, you’ll see your meter reading: eight digits, with “kWh” towards the bottom right of the screen.
  9. For your peak reading you’ll see “IMP R02”. A second later, you’ll see eight digits, with “kWh” towards the bottom right of the screen. You’ll only need to take the first 7 digits when taking each of these readings (i.e. nothing after the decimal place).

Gas meter

  1. Press 9 on the keypad.
  2. The word “VOLUME” will show on the screen.
  3. Your gas reading, in cubic metres (m3) will appear.
  4. Take the first five digits as your reading

Smart electricity meter

Your electricity reading will usually show up automatically on your meter’s screen.

If it doesn’t, press the ‘A’ or ‘OK’ button to show your meter’s different readings. You may need to press the button a few times, until you see ‘Total Act Import’.

Your reading will be shown in kWh. We don’t need any numbers after the decimal point.

Two-rate meters

If your smart electricity meter has 2 rates (usually a day rate and a cheaper night rate), here’s how to find your readings.

Press the ‘B’ button for 2 seconds to bring up the meter’s readings. 

Press the ‘A’ button to go through the meter’s screens. There will be 2 readings labelled ‘Rate’, both shown in the unit ‘kWh’ – these are your meter’s current readings. Usually, the higher one will be your meter’s day reading, and the lower one will be the night reading. We don’t need any numbers after the decimal point.

Smart gas meter

If your gas meter’s display is blank, hold the ‘A’ button for a few seconds to wake it up.

Press the ‘A’ button a few times until you see ‘Meter Index’.

The reading will be in the format ‘00123.456m3’. We don’t need any numbers after the decimal point.

How are customers protected when a supplier collapses?

Its still unusual for an energy supplier to go out of business, but everything is possible and sometimes it happens. Luckily for everyone, there are procedures in place to make sure everyone involved is protected. 

If your energy supplier were to go out of business, Ofgem (Office of Gas and Electricity Markets) has to reallocate you to a new energy supplier. The new supplier is called an SoLR, which stands for Supplier of Last Resort. In January of 2021, Ofgem moved 360,000 customers to EDF when Green Network Energy folded. Ofgem has several factors to take into account when reallocating you to a new supplier which are:

  • Issue bills with no delays
  • Answer all call centre enquiries
  • Reimburse customers credit balances, and whether they will do this voluntarily.

This means that no matter who you get your gas or electricity from, there will always be a safety net to stop disaster striking.

The customers who have been transferred will be given a deemed contract, which must be similar to the contract you were previously on.  A deemed contract means you will usually be paying a very similar amount to your previous contract. However, the new supplier will be taking on a lot of customers, therefore the deemed contract might be more expensive than your old contract. This is because the new suppliers are taking a risk by buying a large amount of wholesale energy last minute to supply to you, therefore they want to make sure they are covered.

Ofgem recommends not switching supplier yourself, as this will be sorted by them automatically, and you will be shortly contacted by the new energy supplier (your SoLR) who will inform you of the change and any additional information. You don’t need to do anything if you don’t want to, it’s perfectly fine to stick with your SoLR, as usually it will be an incredibly similar service provided to you, but you do not have to stay with your SoLR. In fact, the initial contact from your SoLR will detail the options you have in switching to a supplier who better meets your needs.

All you will have to do is take a meter reading.

If you do choose to stay with the SoLR, after six months with them the deemed contract will end. You will then be given a contract on the SoLR’s normal rate. It is likely to be their standard variable rate, however, it is worth checking within that initial six month period how much you will soon be paying.

It is possible (under supply licence condition 9) to claim “last resort supply payment”. This means its possible to receive compensation for additional costs that might occur for you due to the switch from your old supplier to your SoLR.

You might be wondering (FAQ’s):

  • Will my supply be cut off?

No. The SoLR system means you will be switched to a new supplier automatically by Ofgem. You will be informed of this by your new supplier – the SoLR in question.

  • Will my smart meter stop working?

Most likely not. It should just carry on working with your new supplier. However, if it isn’t corresponding with your new supplier, it will exist only as a “traditional meter” until they can get a compliant meter to you.

  • Will my bills increase? 

Most likely not. Part of the process of choosing a SoLR is making sure that the costs are similar amounts to what you have previously been paying.

  • Should I cancel my direct debit?

No. Wait until your new supplier contacts you and they will tell you what (if anything) to do regarding your direct debit.

  • Will I lose my credit?

Most likely not. Another factor in picking your SoLR is attempting to pick an energy suppler that will provide a compliant service to your credit. However, the SoLR is not legally obligated to do this, so they may not – this is something to be aware of, but they will contact you to let you know how they will work it out between you.

  • Who do I pay my debt to?

You will have to pay someone. This might be your new supplier or your old one, dependent on how Ofgem, your old supplier and your new supplier have agreed to arrange things. You should wait until you are contacted by your new supplier to find this out. They will tell you.

  • What about my unresolved complaint?

You should raise the complaint with your new supplier and they will review it to see if it still relevant.

Before you settle with the provided supplier from Ofgem, it is probably a good idea to see if who you have been appointed to is the best deal, and as mentioned, you have six months with your SoLR to find out what the bills will look like after your deemed contract ends. It can’t be guaranteed that your bill won’t go up. Ofgem will do their best to find a similar supplier that will meet your needs and cause as little disruption as possible, but this can’t be guaranteed. Most people use comparison sites like Compare the Market and Money Supermarket to find the best deals. This is advisable – but only after you have heard from your SoLR.
