Your supplier(s) will contact you and give you the option to have a smart meter installed, this is for a standard meter and a prepayment meter.
This will then be installed by your supplier(s); free of charge.
You will also receive an in-home device that will show you your daily usage (in pounds and pence), so you can see what you are using throughout the day.
