The first picture is part of a hedge. It has a nice scent to it.
The second one I think is a tree. It's hidden from view except for some overhang.
First one is Escallonia
I'd say Escallonia too.
Could the second be one of the Daphnes? Not something I grow so not sure.
I'd need to see the tree shape and some leaves and branches. Plant growing rather than the flower in hand.
Best guess from that, Deutzia 'Montrose'
That looks spot on, Nut. It grows quite big so it could be seen as a tree, perhaps.
Thanks for the replies, I'll have a Google
