Burnet Saxifrage?

Observation - Burnet Saxifrage? - UK and Ireland. Description: Quite a lot of this growing on calcareous grassland, flower heads loose without the red central flow

Quite a lot of this growing on calcareous grassland, flower heads loose without the red central flower of wild carrot, leaves largest at base and although they do resemble wild carrot they could be burnet saxifrage - which is what my money's on - any suggestions?
