Sorry but it is definitely not Heuchera Sweet Tart. IMHO.

Your leaves have more of a wave to them
At this stage there are many Heuchera it COULD be.
Leaves can change colour in summer when they get more light.
There are now hundreds of named cultivars in UK.
What colour are the flowers? That is something else you need to know before getting an accurate name.
