I'm surprised by that Nick, my most recent car renewal was not due until the 20th July and I had notification and quote on the 29th June via email.
A similar procedure for the other cars also as the year has unfolded, I'm not sure what has gone wrong in the processing for you and Alan..
Neither do I - but a fellow Hopmogger had the same experience last month and never did receive his renewal documents. He never got replies to his emails either.
