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.
Airhead-
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 electrics in this flat are shocking, the work was done by someone who claims to have qualifications and worked for national grid people. The plastic light switches were replaced with stainless steel faced one, and one was a little buzzy when you touched it. Took two days of searching to find that a chocolate block connector had been used and had melted.
Currently there is nothing modern, not even earth loop protection. Want to do it but, will the flat need a complete rewire, the whole system will have to be checked and I think it is dodgy. There is a LED lamp in ceiling light fitting that has a dim light when it has been switched off. Afraid to look in to that one.
