Possibly a daft one! I need to change the extractor fan in by bathroom. It's like for like so pretty simple. I have switched it off at the isolator. Should I also cut the supply at the consumer unit?

Yes you should because some fans have a permanent live and if the wrong sort of isolator switch has been used it will still be live.
You should also be checking the wires are dead with a dead tester or suitable meter using 240v leads.
If in doubt call a professional

It should be a double pole isolator so even if wired up the "wrong" way you ought to be safe - though I would probably want a sanity check with a voltage detector. Or turn off the circuit if you feel safer (but then you might be doing the job in the dark!).1

Call in a pro. "Pretty Simple" for someone that knows what they are doing.0 -
You need to have it off at the consumer unit and have the correct kit to ensure you have safe isolation. The fans wiring can be confusing and if you not sure it may save time and money to get a professional in the end anyway.user1977 said:It should be a double pole isolator so even if wired up the "wrong" way you ought to be safe - though I would probably want a sanity check with a voltage detector.
