You don’t normally need to read your smart meter. Smart meters normally send readings to your supplier automatically - this is known as ‘smart mode’. You can check if your smart meter should work in smart mode.

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 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.

Reading your smart electricity meter

The way you take a reading from a smart electricity meter depends on the type of meter you have.

If your meter has a keypad

If the number on the display is 0012565.3, the meter reading is 12565.

The way to read your meter depends on if you pay:

  • a single rate at all times

  • 2 rates - one rate during the day and a cheaper rate at night

Most people pay a single rate at all times. If you have an ‘Economy 7’ meter, you pay 2 rates. If you’re not sure, check your bill to see if you pay 2 rates.

  1. Press 9
