It would just end in the energy company force fitting prepayment meters along with adding additional charges on top for the trouble. You can't just not pay. For people with a smart meter they will force mode change you to PAYG not even needing to go to the property and when your power goes off you can cry about it.Growing number of people sharing and getting support for not paying.
Current trend seems to be getting a normal (non pre pay) and just not paying.
It's gathering momentum too. Not sure how popular it will get or how many people will actually try it but it's growing.
Also goodluck getting a non smart meter, they are not even installed anymore. Whether it works as a smart meter is a different matter lol
