Replacing wall lights powered from switched socket

[claytm00]

i will replace some wall light fittings for new ones. Need to know if I can work on these without having to switch off power from the fuse box. When I installed these many years ago, I installed a switched socket which was powered from the main socket beside it. Power to the lights are from the switched socket. If the switched socket is 'off' does this mean that I can work on the lights without having to isolate anything?

No.

You must switch off at the consumer unit ( fuse box ) while doing any work to electric system.

As Stardanny says but on a slight separate note... Where you describe a 'switched socket', do you mean it's a plug socket or just a switch? It looks like just a switch from your pic. If so this should be (easily) replaced with a switched fused control unit with correct rating fuse. And I hope that's not an accurate diagram of concealed wiring routes!

And you must use a two-probe voltage indicator, or a multimeter to confirm the power is actually OFF

Always use SAFE ISOLATION PROCEDURES before doing any electrical work

As above, has the 'switch' got a fuse in it (known as a switched fused connection unit or switched fused spur)? If not, it needs to be, typically with a 3 amp fuse.
