TBF I'd rather screwits installed by a skilled person than a lot of supposedly fool proof kit bludgeoned in by dimwits.If you will use connectors that just twist together the wires, what do you expect?
We are hearing about this and the huge smart meter roll out is creating most of it. The meter changer changes the meter (maybe he has to pull the tails or reposition them to fit into a different meter) twisting or moving the tails going to a consumer unit can loosen the conection. Hence the sudden rise in fires connected with consumer units.
The only test they do is a polarity check (they cannot check the customer conections)

It's my opinion that if you disturb/move meter tails as leccy board or sparks you should check them for tightness regardless, but generally all meters share the same L-N-N-L connection order so can be swapped with relatively little disturbance, the rise in fires is due to the quantity of poor work being carried out by unskilled people with no respect to the rules and regulations, (making the introduction of fire resistant CU's somewhat misguided as it addresses symptons not causes, and is adhered to by those not causing the issues)
I'd love to see the stats on how much of this vast upswing in burnt out CU's have recent VALID certification and how many are in properties with recent refurbishment done by everyones favourite cheap labour. It's not likely that sparks have collectively just forgotten how to tighten up terminals properly is it?
On that note, meter replacement whether conventional or smart has always been carried out regularly, as meters need calibration every ~20 years.
Sorry to go slightly O/T but it's not actually that O/T in reality - loose connections cause problems.
