@Katie18184 modt definitely you need boosters as your home is going to be very difficult to network. Sky's WiFi Max bundle might work as thst can get you up to 3 extenders see https://www.sky.com/help/articles/sky-wifi-max.
Personally I think you are going to have to buy your own equipment I would be looking at powerline networking rather than WiFias it uses the mains wiring to carry the data to distant rooms or running ethernet cables . However a good quality home wifi solution might work depending on the layout what is certain it is going to cost money unfortunately.
