Light fitting? I have bought a exotic lampshade for my bathroom, but the light...

I have bought a exotic lampshade for my bathroom, but the light fitting requests to be dangling down, at the moment it is attached to the cieling (if you know what I mean). Can I buy something to change it, or, next to my lack of gobbledygook be best off getting a sparky surrounded by? How much would it cost?
Answers:    You are not allowed a Ceiling rose contained by the bathroom that is why you currently enjoy a batton holder. There is no IP (Internal progression) rating to them. Why dont you get a Thorn 2D IP56 28W Fitting instead of using a lampshade in attendance lb35.70 from Newey and Eyres and put out a decent lighting:

You need to buy a undecided fitting but make sure that you disconnect the electric supply to the lights. It's not a complicated post but please take record of the wires when you disconnect the wires...If your not 100% get a friend to support you
