Hello Mark,
I deal with many properties which have condensation issues leading to mould and mildew growth etc.

You are on the right track in trying stop the problem at the source.

I would go for a fan with a humidity sensor if possible, that way the fan will turn off and on according to the amount of moisture in the air.

If you are going for a timed fan then make sure the timer keeps the fan on for at least 20 minutes.

If your fan will be situated above the perimeter of the bath/shower and less than 2.2 meters from the floor, you will need to use a low voltage fan with transformer etc.

I would certainly advise that you contact a registered electrician to fit the fan as the bathroom is the most dangerous place in the property in terms of electricity and moisture in the air coming in to contact. They will then advise on what fan to use.

Make sure they are quoting for a fan that will stay on when the light goes off.
