Do NOT use Scottish Power - Their customer services process is appalling. No 1 person owns a complaint and they ignore most of the issues you raise with them. I have been waiting for a 3phase smart meter upgrade to be booked correctly since Feb 2024. I have had 3 different bookings made and they were all WRONG. The people dealing with the calls and emails are utterly useless and this is by far the worst company I have ever dealt with. I would avoid them like the plague. My complaint is still ongoing, still no smart meter upgrade and no date given as to when they are sorting the problem. worst service ever! I have a full solar install booked in with no bloody smart meter to use. WORST WORST WORST
