We're doing some renovations right now and I want to take advantage of all the holes in the walls to run some cables so we can add TV (coax) and satellite (F?) connectors to some rooms.
At the moment we have two TVs plugged into coax, and two decoders (one MySky, one Freeview) plugged into the satellite. If I want to add some more connectors can I just split the cables or do I need a booster or switcher of some kind?

Splitters are the way to go, up in the ceiling typically (Depending on cable routes obviously). Splitters usually mean (in satellite situations) that any set top box can power the lnb on the end of the dish, rather than having to have one box left on permanently.
Just to clarify terminology, you seem to be a little mixed up.
You should be using RG6 coax cable for both the TV (UHF) and satellite runs. I would suggest that you have F-type (threaded) connectors for both as well, and use adaptors to convert this to PAL (slide on) connectors for your TVs.
Yes you can just add a splitter, however be aware that it will cut signal strength, and if this drops too low, then you may need a booster. But generally you should be fine if you already have a good signal and aren't running crazy lengths of cable all over the house.
When runnning the cable, try to make sure it doesnt run parallel with mains cabling (or if it must, arrange it so that there is a solid wall stud inbetween), and if it must cross, cross at right angles.
