I'm going to be changing most of my lighting to LED down-lighters soon and thought I'd put in some ceiling fans at the same time as my flat can get very hot in the summer. I know next to nothing about ceiling fans. What are the good brands? Where's the best place to buy from? Anything I should look out for? I'm looking to get 3 fans and they should be quiet in operation. Budget - it really depends, let's say £200 per fan for now.
