Are you a leaseholder or tenant? If you're a leaseholder and not in a block of flats I've not come across a reason you can't core drill the wall and put an normal size extractor fan in. If you're a tenant it should already have a working one. Unless your council is well behind on the requirements to update their properties or you don't have the external wall to allow for it.
