What is the regs on terminating unused cable or even cores of an SWA cable. I know sometimes we can’t remove the cable completely sometimes due to being impractical.
Regs wise I don't know of anything specific - if it's energised then it's still part of the installation and so all the normal regs apply. If it's permanently isolated then it's just another a bit of metal and plastic and likely out of scope of wiring regs (other than for metallic sheathed cables which might count as extraneous-conductive-parts in some situations).
As for common practice, there's probably a bit of consideration of scale and likelihood of reuse - a bit of old redundant T&E or phone cable buried within plaster or concrete is likely to be just chopped off and left.
