I had to have a smart meter fitted as the old gas meter had a small leak and they don't fit any other meters apart from smart ones.
I got a message from OVO telling me my estimated usage..
Fucking waste of time if they have to estimate usage..I send them the fucking readings every month and still they estimate the bills..
Last month I got a bill saying they had underestimated my usage for last couple of years but they won't be claiming the extra back as it was their fault..the extra I don't have to pay was 10 fucking pence.
