The DMP and Switch came today from Ubiquiti Europe - again without a VAT demand. Virgin is being delivered later today and I'll try a basic and partial set up either Friday when we get the keys or Saturday. The Virgin is now self-install and they've given us the new hub 4 but it'll be straight into modem mode anyway.
I have gone a bit long on ports. The price difference between the USW-16-PoE and the USW-24-PoE is 85 EUR and the difference is an additional 8 PoE ports for the money. I thought I'd rather overspend £75 and have an extra 8 PoE ports meaning we can have all PoE devices inc cameras connected directly to the switch. If we don't now buy PoE cameras it'll be a waste.
I'm going to set up some of it partially for a week or two with wires all along the floor and APs resting on shelves so we can be 100% sure on exactly where we're drilling holes and placing APs. After this I'll factory reset and have it all drilled in and mounted properly. I do think a few of these will just be hidden in cupboards like you suggest. Much later on if 4 APs somehow don't give the coverage needed I'll think about adding one or two more Vs swapping some or all of them out with the long range U6-LRs. I'll probably add another 1-2 Flex Minis or 8 port Flex Lites once we're a bit more settled and have TVs and desks set up.
I'm going to have help installing it physically from a guy who wired up my in-law's house and sister in-law's house with CCTV and ethernet ports. I'm happy to set up the network myself but I'm not willing to go three floors up up a ladder with a drill and after all that probably drill it in the wrong place. We need to change the ariel on the roof so will have him out anyway.
It should be fun to compare notes. Thank you for the recommendation for cables and rack. I was watching rack set up videos last night on Youtube and think I'll end up with the rack wall mounted up near the ceiling in the loft.
