changed to another supplier and they needed to fit a new one
Chances are that the meter currently fitted is a SMETS1 specification. Only SMETS2 counts towards the government targets, so unless you're one of the 1% with SMETS2 meters, or they can do a OTA upgrade, there's a very good chance you'll need these meters ripping out and replacing.
<Pitifully, with sympathy and sadnesss>Why did you agree to have them fitted? The Commentariat have had near universal agreement that smart meters are a POS, so it isn't as though we didn't warn you.
