Smart meters should not adversely affect the stability or performance of home wireless networks. Although WIFI network devices, including our smart meters, operate on the unlicensed 2.4 GHz frequency band, they don't necessarily overlap on channels.

Does a smart meter need Wi-Fi?

No. Smart meters use an entirely separate, bespoke wireless system. You don't need Wi-Fi in your home for it to work and it won't use your Wi-Fi if you have it. Your smart meter and in-home display communicate via a secure national network which is solely for smart meters.

Is there a downside to having a smart meter?

Although smart meters can help you keep track of your energy use, they could also drive up anxiety with elderly or low-income households if they're constantly reminded of what they're spending. This could lead to people depriving themselves of adequate heating or lights.
