HI Rebecca Yeah thats quite common for wiring of that age. Rewiring would be recommended but essential if you wish to install a class 1 metal fitting. An electrician finding this would have to install a label at the consumer unit stating that circuit number? does not have an earth and therefore only plastic fittings can be installed. Is it just the lighting that contains no earth? Might be worth getting an electrician to do a check on your electricial installation to be on the safe side Hope this helps Thanks Russ
