170A: Regulations relating to ability of consumers to choose preferred electricity retailer
You could also call this:
“Rules about choosing your electricity company (no longer used)”
This law used to be about how you could choose which company supplies your electricity. However, it’s no longer in effect. The government removed this rule on 8 August 2001, after it had already stopped working on 1 April 2001. They took it out of the law books by making a change to the Electricity Act.
