My cooker sits under a chimney breast. When I first moved in, there was a strip light in there and what looks like a regular window extractor fan. I can only assume the previous occupants didn't use the top of the cooker as I managed to melt the fan within about a month of being here So there is this greasy melted plastic thing above the hob which no longer works (I've disconnected it now) I really want to replace it with a proper extractor thing that I can clean and is designed to cope with the heat from the cooker. Is there such a thing in existence and who do I need to get to install it? An electrician or a kitchen specialist person?
