Looks like Choisya ternata 'Aztec Pearl'.
No plant seems to do well from cuttings taken while flowering, but if you can find non-flowering sideshoots you could try rooting those as softwood cuttings.
Or waiting until mid summer for semi-ripe might be more effective.

Thanks for your your suggestions - will wait until mid summer. Cheers

Hi, welcome to GoY, I would say Choisya aztec pearl, but the leaves are wrong or C ternata, and yes to semi ripe cuttings in summer, Derek.
