My electricity meter, which was installed when the house was built in 1985, ran backwards for quite a while, when we generated plenty of solar PV. Our suppliers were of course, told of the type of meter, before the PV was installed, as part of the application for feed-in tariff. However they chose to ignore this, and then got arsey over my bills. Well sorry mates, but you were given the opportunity to change it! I was being awkward and saying you can't change it unless its a smart meter, but we both new that wouldn't hold water. They did eventually change it, but the haggling over consumption dragged on a bit.
In other news, I have another appointment for installation of a smart meter, on 16th November. Apparently the first thing he will insist on doing before he installs it, is turn off the gas. That could take him a while, as there's no gas for quite a few miles from here! What he might be better advised to do, is ask me to turn off the PV, if he doesn't want to be electrocuted. We will probably then have the conversation around "oh, you've got PV, we can't install it", and "Oh, we can't get a data signal". Well that's your effing problem, I've made 3 formal complaints to you about it, so bleedin' well sort it!
