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

I thought you couldnt put JB that need to be inspected under floorboards? I may be wrong....

Strictly speaking that would mean just about every house in the country is non-compliant in that respect, i consider it lucky if I see a jb under the floorboards normally it's choc block and tape! Or sometimes even twist and tape, or sometimes even just twist!

Good bit of kit? Why did everyone stop using the ceramic ones? Let's twist all our cables together and hope they don't snap? Metal fatigue?

Twister Pros???? Isn't that a giant step backwards?

 

[Knobhead]

Screwits were the ceramic ones, even as an apprentice I refused to use them. Then all the cables would be multi stranded not single core as now. They were rubbish 40 years back, what makes them better now?

They've got pro at end of there name?

I found these things in my parents' house which was all wired in VIR. The wires were joined with these screwit things & enclosed in old round tobacco tins.
