They supplied my house in Scotland, but kept billing me for a house about 28 miles away with the same road name.and the same house number. Spent nearly 2 years trying to sort this out and eventually changed supplier. Recently dealt with them when a house I rented I decided to put up for sale. The Tennants gave the wrong readings to Scottish Power on leaving, (too high). I guess I could have ignored this as I would have been in pocket, but tried to change it by phone twice. Internet account still showed incorrect values and would not accept the correct ones. Tried again using the app. This time with success, but from previous experience expect more difficulty ahead. On the plus side the customer service personnel and attitude is always first class, it just seems that the infrastructure is full of holes.
