I am wanting to have a shaver socket installed in my bathroom. I asked an electrician I work with about this and he said you can usually feed one easily as long as you have a permanent live cable in your light fitting. I Unscrewed the ceiling rose but only have a switched live, neutral and earth. I then remembered that the downstairs lights are all connected to a junction box, so I go in the loft and also find the upstairs ones are connected to one ( see photo ). Is it possible to have a socket fitted or are you looking at a major job? Any help would be appreciated, thanks!
