Sorry but that is wrong! From a little period investigating this, the only reason you would even interact with anybody, is that you have changed address, and that's it! As long as you are on the electoral register, you are good to go.You have to do it annually so worth checking that you’re registered.
As a footnote, I am quite puzzled why the people in charge of this, displayed this confusion..Baffles me, and even if you google it, it puts a fence up. Quite funny really.
