Interesting that SSE are saying they can fit an E10 meter now. Be interested to know if you get one! I finally got mine fitted (free) from SSE a year ago, but it was 85 minutes out, so have just had a new one fitted (now 7 minutes out!). The engineer who fitted it seemed to know what he was talking about.. said there probably would be an E10 Smart meter soon. He said to mention to the powers to be that I have “four port time of use” meter (whatever that means, as he thought this type would be out sooner, as they are similar to the E7 ones that apparently are now available.
