Hi, You are right SP don't monitor this site routinely, you can alway complain directly to them and say your property is unsuitable, not a refusal.
The Smets 2 meters are said to have a more powerful local signal and therefore better for flats like yours.
We had smart meters installed on the 2nd October and they have not worksed since then. We have reported it numerous times, only to be told it will be sorted. WE have not had a bill since and been fobbed off with we will use an estimate bill and smart meters are compulsory by law.
