this is mainly to do with cookers. the wording I have is" any appliances in your home that you own are your responsibility-not the landlords"( don't want to get into fires because the chimney is the landlords) but my understanding of this means in that situation it is just a visual given that a lot of cookers arnt maintained do you just write requires servicing if the cooker looks passable and leave it at that or should I do more the reason I ask is some site cant remember which said check for carbon monoxide and that implys a much more thorough test
