Disconnected wires in wall

[dedwards96]

Hi

I'm looking to redo my kitchen early next year and am hoping to remove a defunct central heating timer from the wall and replaster. Once the timer is removed there will just be an exposed T+E from the wall which is disconnected (tied in a knot and buried in insulation) at the other end near where old boiler was positioned.

My question - can I simply chop the exposed T+E back as far as cutters will go and have the hole filled and plastered?

Hope that makes sense. Thanks.

If it is definitely disconnected both ends and made safe so it can never be made live then yes.

If you are certain it cannot be reenergised. If it can’t be removed... pulled out... etc I’d be tempted to connect all the cores together before burying it.

That way, if someone finds this unused cable in the future and tests it, wondering what it does, it’ll show them a dead short.
If the cores are left disconnected from each other, the testing would show the cable as “healthy” and someone may use it
