Or at-least no reason that's apparent to you.
It's quite common that the UK regulators (CAA, PFA or BMAA) will decide that the level of proof provided in support of a foreign aeroplane aren't convincing - leading to redesign, different limits or in some cases just no approval at-all.
Opinions differ as to whether this is reasonable, or the UK should be much more willing to accept foreign aeroplanes on the basis of service experience, but I can't see the situation changing in the foreseeable, save possibly for the proposed 115kg category if it happens.
