Due to an accident where a lodger has fallen off her first floor flat roof, my sister has been told by her insurance company that she must install a safety railing. The house is in a conservation area but not listed building. Do temporary ie removable railings need planning consent? Also is it an offence under planning laws for anyone to actually go on the flat roof for any reason? There's nothing in the the planning consent for the flat roof about this. I need to get a barrier up fast as she wont have house insurance otherwise.
