Electrics / doing it yourself

[physichull]

I have a ceiling rose in the third bedroom that is a "loop in" wiring configuration (i.e. a wire going to the switch and coming back, and two L-N-E cables).

I have bought a light fixture for it, but this requires getting rid of/moving the ceiling rose into the loft space above and replacing it with a junction box like this:

Which is essentially a sealed ceiling rose junction box. I then plan on running a short L-N-E cable to the light from the box (the light fixture itself will only accommodate one L-N-E connection, hence having to relocate the rose).

My question is, I see myself as being perfectly capable of doing this, but are there are requirements that mean I have to get a qualified electrician to do this?

I read through some of the Part P T's and C's and it was still unclear whether it was permissible to do the task on your own. It said if it was anything like re-wiring to the consumer unit, anything in the kitchen or bathroom then you should get an electrician to do it.

This seems to suggest I could do it myself:

I still don't get why he needs the j/b really, since if he's keeping the rose in the attic he could just use that as the j/b.

This is true. I could just use the ceiling rose itself but I figured it would be better and more "suitable" (or "correct") to use a junction box instead.

The reason why the ceiling rose has to go is because the light fitting I have will not fit to the ceiling with the ceiling rose in the way.

It's sort of "like for like". Essentially, the ceiling rose is just going to be moved to the loft side of the ceiling and new wires to run through to the light. Except the ceiling rose will be replace by the junction box (which performs an identical function).

I have started using Hager J501 junction boxes, found them easier to use than the round ones, plus they have cable restraints.

Cheers for that, they do look even more suitable actually.
