Link between one light fitting and socket circuit?

I agree it is something that I would not have found with any standard testing, it would have showed up pretty quick though once the new cu was fitted as I fit SPSN RCBOs for all circuits as standard.

You shouldn't be ripping floorboards up whatever mood you are in! A tradesman should be carefully lifting them so as to cause the minimum possible damage. Ripping people's houses apart is what demolition contractors and plumbers do.

I hsve to say this has caught me out as didn't pick it up, and it's only by chance it's to come to light as they were on different sides of the board but could very easily have been on the same side then I would never have known.

Ive got three more boards lined up for this month so will look a bit deeper at the pre testing to try to eliminate anything like this again.

as forge comment about ripping the floor up, it was just an expression.

You'll not catch something like this on pre-change testing. Not unless you are going to spend more time devising bizarre tests than actually doing the job. You just have to suck it up sometimes and hope you've allowed enough contingency in your price. If not then you just have to accept that some jobs go wrong and make a loss, shyte happens sometimes and you just have to accept it.
