Do you need to power the tado and APs?
If the domestic power goes down your central heating won't be doing much without pumps and the APs will be limited if the BT line goes down on a local outage.
Have you considered solar panels and a storage battery? 😂
Grumpy_Git-
There’s no BT line, not sure about how the FTTH is powered. Could always add a 4G dongle to the AP, still would need power to another AP at another location (which is the wfh office - granted that could also be a larger power station that way I could also power the displays…)
I agree adding tado to the list above was not necessary :-) House batt and solar would be 20-50 times more expensive than what I have in mind, plus might have to deal with bad workmanship.

Looking for a 'battery backup' to provide my modem/WiFi and other things with 12v and 5v. Maybe 50W or so of power, passthrough charging and preferably screw terminals for output. But I want LiFePO4 cells, not regular Li-Ion/LiPo chemistry.
All options I could find were camping-oriented 'power station's with 240V inverters etc. on them (with huge capacity), so the price jumps to £300-£800 range as opposed to what would be a £50 gadget. I would get more than one to power multiple APs + hue/Tado/blink etc. I don't want to just use a passthrough powerbank and run the cells flat in a few months/years, if not worse.
I could get a LiFePO4 pack from HobbyKing, a chemistry-specific charger circuit and bunch of buck-boost regulators and make it a project but I don't want to do that. To make it viable you'd need
to design cooling, a case and other not-fun things, where I just want to get a few and set it up.
