How do gas companies etc know which houses physically get the gas they are selling them?

Question

How do gas companies know w when you’ve changed provider?

So I’m moving house and am switching provider for pretty much all of my utilities etc. So how do they, my new provider, start supplying my house the gas instead of my previous provider. I’m assuming they use the same pipe but it’ll contain the whole areas gas and smaller pipes would branch off up streets and eventually into houses wouldn’t they? How do they direct only British Gas gas into my house instead of Scottish Power gas?

I’m stoned so please excuse me if this makes zero sense

Each house has a gas meter. They read the meter once a month and charge you for how much the meter says you used.
