You won't need to have a new smart meter if you already have one. If you have a generation 2 smart meter we'll be able to communicate with it right away. A generation 1 smart meter has all the functionality we need to pass on your savings and earnings it will just take a little longer until we're able to communicate with your meter and pass on these savings, we'll make sure you have the right tariff to still earn your savings until then.
Most generation 1 smart meters communicate with your supplier through the 3G mobile network. Unfortunately, a number of different systems, not linked together, are used to manage these meters and so if you change suppliers it is likely that your new supplier will not be able to operate your Smart Meter and it will become a ‘dumb’ meter for operational purposes. There is a programme of work being carried out to link and integrate these meters – this will take place over the next 12 months and hopefully make your Smets 1 Smart meter smart again.
