If you have nine wires coming out of the ceiling get is someone who is competent to do the job.There are nine wires there because the ceiling rose has been used as a junction box (as they can be) and in addition to the switch conection there is the "ring" connection too. one of the wires will be permenantly live and atleast one more will be aswitched live. So you need someone who can sort them out, there are at least two different ways of indicating which is which. BE VERY CAREFUL
