in my bathroom which has a big window the wiring is 25 years old the extractor fan (in line about 700mm from vent above shower) is connected in parallel with the bathroom light. so if i switch on the light the fan comes on. is this now illegal? also everything else in the bathroom is on rcd at mains but light (and hence fan) are not. should i change this? finally the light on off pull cord in in the bathroom near the shower (bath/shower). it is not above the bath and is 2.9m from bottom of bath (and 10cm outside of bath edge). is this ok for the pull switch? i could provide power to light and fan from the mains in the loft which is rcd. should i do this?
many thanks for any help
