Using the nationally recognised green, front-window sticker system. So out of five.
Please be honest, there will be no judgement in this thread.
I would say mine is normally 4*, as we are all fairly tidy. However, recently, it would have to be 2* or 3* as we are coming to the end of our tenancy and we are going to be forced to fork out for professional cleaners in about a week, so why bother?
