Hi yes no problem, the size and rating of the fans required depends on the dimensions of the rooms that require ventilation, I would need to know the following: Room width, length and height Type of room: ie bathroom, kitchen etc Where you would like the fans installed What type of material the wall is constructed from and its width. As a guide, small 4 inch fans can be installed in half a day for £250 and larger 6 inch fans can be installed in a little over half a day for £350. Prices vary depending on the size of the fan and the size of the hole required. The price is also effected if you use in line ducting fans or wall/ceiling mounted fans. An air brick may also need to be installed. Alfie
