I appreciate that people might not be able to help. I Just wanted some advice so I was armed with the right information when LL's handyman comes out.
I switched on my bedroom light tonight, and was met by a huge firework display. On further inspection, the light has burnt up the wire (single bulb on wire) and the wire had snapped sending the bulb crashing.
All lights went out and so checked the fuse (old fuse box) and the wire was very thick and twisted, my dad seems to think that it is very old wire, I have replaced this with the normal 5amp fuse wire now and put the lights back on.
The rest of the house is also old wiring, we have one old style plug per bedroom with no on/off switch.
We have someone coming out this weekend but wanted to check that there is no immediate danger and should I be asking for anything in particular.
