No 2 does look like viburnum but it's quite big so I don't know. (if it were smaller I would say the leaves look lie viburnum tinus). There are loads of variety and the leaves vary a lot. sorry not helpful
Tree 1 is deffo pittosporum. Tree 2 - trunk looks like eucalyptus but the leaves look a bit soft - eucalyptus leaves are very dry and much narrower than that usually (they are natives of very dry climates).
So no idea but I don't think they're anything to worry about TPO-wise
Tree people can be a bit sniffy - I asked the council to come and cut the hornbeam on the pavement and the tree surgeon arrived and said 'that's not a hornbeam, it's a whitebeam!' like I'd deliberately lied to him or something
Well, I'm in two minds about Tree 2. The leaves do look like viburnum tinus but (thinking of the vast one in my parents' garden) I would have expected the canopy to be much more tightly-packed. Could you take a leaf into a friendly local garden centre?
