How much are meter prices?

Hey, I have gas, electric and water meters and was just after a ballpark figure of how much it costs every time it increases by one [every unit].

I know it's different for companies and areas, so a ballpark.

In a month:
My water went up 5.
My gas went up 5.
My electricity [apparently from my friend] went up 210.

This seems a bit high hence why I'm asking. I had a quick check online but was only met by forms to fill out.

Thanks.
