Thought it was a Deutzia at first but it does look like a wegeilia.
Anyway, they are both pruned the same way.
I would lift every branch and cut back every flowered section to where new shoots are growing. I also look to take out a couple of old wood back to the ground.
(funny thing to.prove how effective pruning is. A neighbour simply squares every shrub he has and it means his deutzia flowers amongst the leaves. Mine has arching branches high above the emerging foliage fully clothed with flowers. I try to explain how he should prune his but he likes his table mountain shrubs )
