It will be Freesat you get from your dish, not Freeview. Normally if you have a proper Freesat box it will automatically update the EPG channell list if channels are swapped around or deleted. If you have a cheap Satellite box it doesn't dyna.i update, you find you are presented with about 500 channels, most of them drivel. It's worth doing a rescan, I do a first time on my non Freesat receiver from time to time, .my other Humax Freesat bot sorts itself out. I've got a 1.4.metre box and get the HD versions of the SD channels that have gone off air so everything should be good.
