I've just tried - and failed - to confirm voter details in our household. I received the form, which was dated 16 August 2017 last month. As usual, it had the two-part code to confirm details either on the Household Response website, by text or by phone.
The codes did not work. The website told me that my council would be sending out new codes soon. Tried confirming by phone; again, no go.
While I was worrying about whether new forms would be sent out before 10 October (the date by which you're supposed to have confirmed), I noticed the year on the closing date on the inside of the form - 2016 - so, last year's form with last year's codes!
I'll be ringing Haringey Council tomorrow morning about this, but I wonder how many people will not bother to reregister to vote...
