I will be wiring in 2 x LED ceiling lights,is 1.5 mm twin & earth the
correct size, or should it be 2.5 mm?

1mm is the common one for lighting circuits. You could use 1.5mm if you
already have it. 2.5mm could be too big to fit connectors, etc.

Depending on cable routing you may need 5Amp rather than 10Amp circuit
breakers if you are using 1sqmm cable.

Surely 5 amp is the common one for lighting circuits? Unless stupid enough
to have only one in a house?

It always used to be when we had fuse wire! But my current house is
fiited with no fewer than trhree lighting circuits, each with a 10A
breaker. I don't know if I am entirely alone in this, but I certainly
felt a little guilty using a couple of meters of 1sqmm three core and
earth I happened to have for a repair. Though it is probably alright
because of where it is run.
