The only way to operate one in the UK would be under a UK permit to fly.
Nominally it exceeds the spec that the LAA can recommend permits for, but they occasionally make exceptions. That leaves getting your permit directly from the CAA; probably more expensive.
Either way it would be limited to day/VFR operation, rather negating the benefits of being pressurised if you can't use class A airspace.
Operating on a foreign register is effectively ruled out by AWN52 as said above.
