Planning ahead for a bathroom refurbish, I am looking for opinions on wiring in bathroom extractors. On our previous bathroom I wired the fan into the bathroom lighting circuit using the switched Live to trigger the extractor which had a run on timer. However, I have come across one installer who recommends wiring the extractor separate to the lighting. To benefit from run on timers a loop is connected from permanent live to switched live in the isolator and a secondary switch is included in the switched live connection to the extractor to trigger it. This means you do not need to switch the light on when not required. Any opinions on which way is best?
