Depends on individual installers. If they’re happy & you’re happy that your house is well ventilated, etc, the install will go ahead.
Just make sure you fully test the system before they leave. Sky Q works very differently to HD & communication errors between the main box & mini boxes are common. Make sure you test all the boxes, particularly if you don’t have Sky Broadband.
Also make sure you’re given a main box capable of UHD & HDR if that’s part of your package. There is a shortage of the latest version Q box at the moment and Sky have been installing the older V1 boxes which are not HDR compatible.
