Thanks again Nick. Yep, you're right, the DHCP range does start at .100 so I'll update my diagram (not that I really need the diagram). Also, yep, good idea to put printer on reservation or static outside of DHCP range. I couldn't quite remember how WAP's worked so as you've said, I'll configure that separately.

I've tested putting switch in to enp2s0 and my mac into the switch and all is working nicely so very pleased. What is the reason for moving the modem/router onto a 192.168.2 network please?

I've had a look at the advanced settings on my modem/router and can't see a bridging mode at the moment but will take another look tomorrow.
