First, the law doesn't apply to "every property", only privately rented accommodation.
Secondly, I'm not trying to "prove" anything - I'm just showing that the law quite clearly says that such accommodation must meet the standards of the 18th.
You have a number of options concerning that.
You can deny that it says it.
You can say it doesn't mean what it says.
You can go and complain about it to the people who wrote it.
But one option I don't think you have is to get argumentative with me when I say that the law requires something which it quite clearly does, and will continue to say until someone pays the lawyers for a pinhead dance and a court rules on how it is to be interpreted. None of us here have any standing to rule on what the intent of Parliament really was, and no matter how many and how often people say "yeah but the regs say...", the law will continue to say what it does.
