We have featured information supplied by Trust Power saying the firm would remove a smart meter on your home and replace it with an analogue meter if you switched to using them for your power supply.
However, for people living in Wellington the issue is not so clear cut. It seems the firm is not able to replace meters in this area.
If you live in Wellington then please double check with Trust Power before switching.
One option is to ask your current power supplier to remove the wireless chip from your smart meter.
It appears it is far easier to stop a smart meter being put on your property than it is to have it removed afterwards.
