Just found out that extending a ring main with junction boxes is

longer allowed in the IEE regs.

You found out from an unreliable source.

Whats wrong with junction boxes? The floorboard above them will
be
screwed in place and not nailed and marked as an access point for
the
junction boxes.

They have to remain accessible, otherwise use crimps.

On the subject of crimps

1) What's the correct way to join 3 conductors (e.g. to create a spur
from a ring main) - one size up butt conector? piggy back spade
connector ? ring terminal and bolt?

2) how do you finsh the job off? Heat srink? Place in an enclosure of
some sort? wrap in insulation tape? Presumably where the outer cable
sheath has been removed the wires need to be protected by something?
