Some people have got the wrong end of the stick on the Citiworks ruling. But some companies appear to be deliberately spreading misinformation to further their own ends.
Just to be clear the ECJ ruling doesn’t make private wire illegal. It does require that private wire networks allow third party access. In other words, if I operate a private wire network I have to allow other electricity suppliers access to my customers. This can be done in a couple of ways, but it can be done without changing the private wire arrangement. In other words, the network will still be license exempt.
So if you come across people saying otherwise, you can contradict them with confidence.
