Emergency cut off

Where is the emergency cut off on a smart meter?
On my current meter it is on the back, which is difficult to reach as the meter is against a wall

I dont actually know as I dont have one, however I googled this image and there is a turn off valve before it enters the meter.

Could you post a photo of your meter to explain what you mean? Most meters don’t have any switches on them, and smart meters are no different. For electric, you typically have a separate isolation switch installed immediately after the meter output. For gas, it works as scudo has shown, with an isolation valve at the input which will not be changed or removed by a meter replacement.
