OLD light fixture can u still use?

[amateurSparky]

In my sister house there was a light fitting under the stairs which to me seems to be an old fitting. Never seen it in my life. I was tought on ceiling roses. It just has 3 terminals like a plug. Then two screw holes to fix it to the ceiling. Are you even allowed to use these any more? Do you think it needs changing to a ceiling rose?

Also we had a DIY accident. My brother in law put a nail into the wire which tripped the breaker. I was forced to replace the wire but am only qualified to lv2, does this mean I need to get this recertified? The installation was checked by a qualified electrician before this. I've not changed anything just put it back the way it was.

One of these? http://www.toolstation.com/shop/d190/sd2633/p46677
If so, no need to change it.

If you have replaced the damaged cable, the circuit should be tested afterwards, same as with any repair or alteration.

It should be fitted with a back plate if it is mounted onto a normally flammable surface but other than that they are fine.

Schedule 4 of the Building Regs specifically states that replacing any single cable is not notifiable work - so yes, you can change this yourself if you are competent to do it safely. There is some debate as to how much testing is required - most DIYers would not have any test gear other than possibly a multimeter.
