If Sky Hub is running reliably, then ideal solution is run an Ethernet cable from the Sky Hub to a wall mounted socket in each room. Then just buy a cheap £10 Ethernet switch to hang off that infrastructure socket, and can then even if people get ham fisted all they break is a small switch.
For infrastructure cabling you want solid core CAT5E, that is copper rather than stranded or CCA (Copper Coated Aluminium)
Sockets are pretty cheap £2.19 each on Amazon
just need a back box again Amazon or local DIY place.
A krone tool and a basic cable tester
are worth getting to make things simpler.
I have read up a little and using the switch by adjusting sky hub settings to issue IPs one option? -easiest method?
I don't understand what you mean by this, switches normally don't have an IP address. Only Managed Business grade hardware usually has that sort of thing and is massive overkill for a simple home setup.
A mish mash could get you through a temporary issue, but if going to do it, might as well get the basic wiring in place.
WARNING: If you plan to run some of the Ethernet outside, then it needs to be exterior grade cable due to UV light breaking down the insulation.
