How to read your smart gas meter

This advice applies to England

You might need to read your smart meter in some situations, for example if:

  • you’ve just switched supplier - you normally need to send the first meter reading yourself

  • you switch supplier and they say they can’t connect to your meter - this can happen if you’ve got an older smart meter

  • you want to check your meter reading - for example, to see how it’s changed recently


Call your supplier to give them the reading - or check if you can submit one on their website or app.

If you can’t get to your meter, your energy supplier might be able to give you extra help to read or move your meter. You can check if you can get extra help from your energy supplier.

Check your meter - not your smart energy monitor

When you get a smart meter installed, you'll also normally get a small and portable device with a screen on it. This is called a ‘smart energy monitor’ or an ‘in-home display’ (IHD) - it either plugs into a socket or runs on batteries.

It can be easy to confuse your smart meter with your IHD.

You can check how to use the IHD for your smart meter.

You might be able to take a reading from the IHD but it’s best to take one from the meter itself. The meter will be fixed to a wall or board - it’s usually somewhere like a kitchen cupboard or a box on a wall outside your home.

If you can't find your meter on this page

Check your meter says ‘M3’ after the reading. If it says 'KWH' it's an electricity meter.

If you're not sure if it's a smart meter, it might be a standard meter instead. Check how to read a standard gas meter.
