How do I know if I have a smart meter?

If you no longer have your meter read or have to provide meter readings you probably have a smart meter.

If you have had a new meter fitted since January 2009, no longer receive estimated bills or have been told by your energy supplier that you do not need to send meter readings anymore, then you most likely have a smart meter. 

One way to tell for definite is to look at your electricity meter. If the serial number on the meter starts with ‘19P’ then it is a first-generation or SMETS1 smart meter. If the serial number starts with ‘19M’ then it is a second-generation or SMETS2 smart meter.
