Yes and it’s not really optional in reality.My meters are old school and i am with Octopus. They are offering free upgrade to SMETS2 in my area.
Haven't signed up yet, but worth doing? There was a lot of negativity when smart meters were first introduced and i haven't really looked into it since.
Like the above poster, I’ve saved a fortune from being able to access tariffs which change price up to every 30 minutes.
All staying on a dumb meter guarantees is that you’ll pay the most for your electricity.
