Am just chatting. I liked split load board so the lights are on one circuit and everything else on another. At least the lights stay or the plugged in lamps.
With the electrical regs, it is not worth me touching the fuseboard. If I have to pay someone to certify it will be the same as if I paid some one to do the work. So might as well get a tame sparky to do the work when he slack so at least my money goes to a mate. But then my sparky mates are always busy.
The LED ghost current needs further investigation, the light fitting is three spot light arrangement but the one of the three positions has this problem, just annoying that it is a bedroom light.

The cost does depend on your local council. I could probably justify it on my own place because the labour would be more than the certificate. If you have the qualifications it's tempting to forgo the bullshit and easier to ask for forgiveness.

That's what I meant about only one light being on, its the one using all of the tiny amount of current that is in the lighting wires because they run next to some other wires which have current running through them at some point in the circuit. Case solved :)

On the RCBO vs RCD topic. It's thought of as a better option to have all rcbo than just one or 2 rcd, the reason the regulators give is they worry that someone looking for the box to switch the power back on could fall down the stairs if the whole house is dark. Also some people can't figure out how to isolate the circuit that's causing the problem and get the rest running so they're stuck until a responsible adult arrives!
The regulations are moving in the direction of all RCBO cu's, they are recommended at the moment.
LED lamps glowing because of a tiny "ghost" currentare very common, often caused by proximity to other cables. Ghost current occurs very frequently, electricians meters often have a method of ignoring it. It's only one because it's using all of the tiny amperage available.
