intermediates as you want.)

'Intermediate switch' is a key word for the OP to look up where a light
is switched on or off from more than one location. You can install as
many intermediate switches on an existing two-way switched circuit as
might be needed.

He is aware of that, and mentioned such.

I believe his question is entirely about regulations; whether you can
have multiple downstairs light fittings on an upstairs circuit.



That's how I read it.

And of course it is perfectly acceptable if the CU is properly labelled
as to what each MCB controls.

There is also a myth that you cannot have a lightswitch fed from two
different MCBs despite 90% of UK houses having got this type of
installation in the hallway switch.
