Can I extend a wire by 15 cm and which is the right way?

[Mark3100]

Hi. I hope you can help me with this.

I’m putting in a false ceiling in my dining room, which will lower the ceiling by ~10cm. The wire to the ceiling light is barely long enough as it is. After lowering the ceiling the wire will be too short. Can I extend it myself legally (DIY)? I thought it would be a simple matter of a 3-way terminal block (wrapped in tape just for good measure). If this is good enough for connecting large light fittings with several feet of flex, it must be good enough for lengthening the flex by ~6 inches - right?

But a quick look at the part P regulations has caused confusion. Does this count as fixed wiring, in which case it’s illegal for me to do it? To comply (with UK law), is a junction box necessary and would it have to be screwed down, or can it be shoved up into the space? Would a Jbox have to be in an inspectable position and does this mean on the surface or under floorboards?

The job just went from dead easy nightmare! Please help!

Thanks,
Mark

You can't have screw terminals in a JB that is not accessible full stop. Not at home so can't check the BGB, but I'm sure I'm right...

I don't like the look of these. At least with wagos you can see the conductor is in.

to be honest mate if you unscrew them once you have made the connection,you will find a perfect twisted cable.give a better connection,imo,but thats open to debate..

Never have liked cables being twisted together, bloody awful, specially in the back of sockets, no need for it, this is just like twisting cables together and wrapping in tape, just replacing the tape with a toothpaste lid!!!!!
