Help with wall lights

[securespark]

I have this evening done all the above tests and the results are all as expected.

I definitely get 240v (using a two pole tester) on this circuit when the switch is closed and 0v when it isn't.

However if I touch the screwheads on the choc block once the light is wired in I just get the continuity buzzer and LED.

In each case have you been testing between the switched live (the terminal with red and black connected to it) and neutral?

What happens to both lamps (the CFL and the GLS) when you connect it to permanent live loop and neutral?

Sorted - cheers for all your help. Took it back to basics, removed all the choc blocks and identified each wire in turn starting with the main live in, then built it up one wire at a time to ID all the different elements - including the set going off to the ceiling rose. Al back together and all working fine. No idea what the cause was but it all works now. Thanks again.
