One cable at the board coming from each 16a mcbAre you quite sure these socket circuits are radials, and not 16A ring final circuits? (Yes yes, I know that would be rather non standard ...)
Your clearly being very optimistic with that comment on complianceCarp design for sure, but I'd be surprised if this was dangerous, or even non compliant, all other things being correct.
If there is any insulation does it really matter if it is significant or not for me you always calculate on the worst possible.Most recently built houses that I have worked on tend to have the cables for socket circuits run in the floor void between floors, dropping or rising to the sockets. There's not usually any need to run the cables through any significant insulation.
That's completely fine electrically speaking. It's literally what French regs specify. 8 sockets max on a 16a radial in 1.5mm.Defiantly 1.5 cable , and all on 16amp circuits. Feels very much European
I didn't have time to add up all the sockets but I would suspect that there is around 6 or 7 sockets on each 16amp radial , possibly 1 circuit for upstairs , 1 for downstairs and 1 for the kitchen , but this would require further investigation
But this house isn’t in France.That's completely fine electrically speaking. It's literally what French regs specify. 8 sockets max on a 16a radial in 1.5mm.
Normally over there they have freezer, washing machine, dryer, and dishwasher on their own runs but kitchen countertop sockets used to be fine on 16a, i think they now have to be on 20a.
Connect all the wires up and it can be fine electrically speaking whether it is compliant in the UK is a different matter and that is the pertinent point of this threadThat's completely fine electrically speaking. It's literally what French regs specify. 8 sockets max on a 16a radial in 1.5mm.

If a cable is running in a floor void is that in free air or is it a duct and given that you can also have heating pipework running in the same void how do you assess the thermal effects of that on the cable
Where in BS7671 does it say you can't use 1.5mm cable with 16a breakers?But this house isn’t in France.
We have to work to BS7671, and have to design circuits with estimated load, installation method, current carrying capacity, length of circuit…..
If none of it mattered, it wouldn’t be there in the regs.
