No, it's perfectly possible - just look at your local DNO's website.
It's necessary when there's a large power draw. Historically when
people have had a workshop with three phase machines or just a very
large house, and increasingly for 3-phase EV chargers and heat pumps
(again for large, poorly insulated houses :)
It's common in some places on the Continent because they have much
lower current limits per phase. 3-phase 32A for example.
It's pretty easy to electrocute yourself with 240V, no need for 440V :)
