Let me preface this by saying that I am comfortable with doing things like changing light switches and power points in my own home. But I generally limit myself to like-for like replacements, but the following is a little different so just want to ensure I do it right.

In my bathroom the light and extractor fan run off a single switch, so either both are own or both are off. I would like to change this to a 2 gang switch so they are controlled individually. I don't want to get a sparky in to do this as I am more than confident with my ability to do the actual actual physical wiring into the switch, I just want to verify the way I wire it is correct.

The current switch is wired as follows:

• 1: Two red wires (presumably positive/phase)
• 2: No wires
• C: One red wire (presumably positive/phase)
• Loop: Two black wires (presumably negative/neutral)

How do I wire the 2 gang switch to give me separate control of the light and fan?

Thanks
