How to read your smart gas meter

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.

An example in-home display (IHD).

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.
