I'd add another 50mm over the rafters, then plaster board, as just 75mm between isn't compliant with building regs
Isn’t 75 + 50 still less than required for BR?

It was OK for me, but that was 3-4 of years ago...
I thought it was 150mm Min, usually done by 100 between and 50 below if the rafters are deep enough. And may have increased further with the more recent regs. But I may also be out of touch as not done one for a while
I think you are right. Target u value is now 0.16 for renovation.
OP, I would be looking to add either another 75mm over the rafters but 100mm would be best.
