So Energy 'So Rewarding'

Had an email today inviting me to sign up for the 'So Rewarding' demand flexibility scheme.

As part of the enrolment process it asks for the last 4 digits of the GUID from the smart meter display. Only problem is that my display has all sorts of numbers - Hub ID, Install Code, MAC address, Serial no - none of them labelled 'GUID'.

Had to call the helpline to discover that what they actually want is the last 4 digits of the MAC address.

Other So customers take note, it might save you a bit of hassle!

    For future references, its the long line of digits and letters in this sort of format (it may have all caps or more dashes separating the characters): 


    It is usually on the bottom or the back of the IHD

    (the above is just made up, not my GUID)
