The cable won't be taken out of the cut out
What sort of cut-out is it? Is it one that is a risk if disturbed? You do not know!
But you have to dismantle the cut-out to unscrew it which will expose live parts that you have no means of isolating and could have up to a 630A fuse protecting it, you short it out the fuse will not operate, you will be severely injured and may never work again or even worse be one of the few electrical fatalities a year!
Moving it like that puts stress on the cable terminations which can cause them to fail, if it is a lead sheathed cable you will also introduce stress into the cable crutch which can cause a failure, if these occur as you move it you are risking injury. If after you are risking a fire
I have attended situations where this has occurred!
If you do damage it doing it yourself the DNO will have to attend as an emergency and charge you a heck of a lot more (if it were me I'd disconnect your supply for breech of contract and illegal interference) if for a subsequent fault they may still find evidence you moved it and charge you for the repair.
Get a quote (a quote is free) and then plan a safe solution, often a bit of work moving the consumer unit means that a move is not needed!
