Any downsides to a smart meter?

[darael]

Looking at moving from EDF to maybe Octopus but we currently have an old Economy 7 meter, is it worth changing this to a new smart one with EDF or after? I'm also going to look at getting rid of Economy 7 as we don't have storage heaters etc etc so no benefit to having cheaper electricity overnight.

I'd change to Octopus, then ask them for a smart meter. Otherwise you could run the risk of complicating and/or even delaying the switch between energy providers with relatively newly registered smart meters. I say this because it can take time for the new smart meters to connect to the network - depending on your area, hours, days or maybe weeks. In my area, my SMETS2 meters were sending readings back to EDF within in a couple of days.
