Hi ​@VictoriaM , the electric smart meter (in your photo) doesn’t show any gas reading. You should look on the gas meter itself.

If the display looks blank, press a button and it should wake up. It will look something like this 

• Gas meters have A, B and C. Pressing C will give you the menu and A & B will allow you to scroll through the options. The balance section is where you can check the reading (when you wake up the meter it should automatically default to the reading screen). Screen 1 - readings, active tariff price, standing charge, export reads, meter mode.

Or, if it’s a Honeywell meter

• Press the middle button once or twice to access the reading. 

Ah, so is it still the old dumb meter then? 

Ah, lightbulb moment. That is the smart gas meter. I didn’t realise there were separate ones. 

Yes, they can each only measure what they’re supplying. So yours is like the one in the picture I added with the three buttons.
