I need to identify a tree in uk.?

Question:the tree is about three storeys tall. the leaves are flat and narrow, about 10-15cm long and about 5cm across at their widest. the leaves are not jagged, but meet at a point. The tree has recently started to produce red-orange berries.

Answers:
The first site listed below has trees that are common to Ohio in the US, but it is useful as you can identify trees by leaf type which might give you some clue as to what you're actually looking at.

The second is a UK based site which may be more useful. Good luck.
