Judging from the leaves and how they are grouped on the branch, I would say it is Castanea sativa which is known as the sweet chestnut. However, fruits (the chestnuts and their husks) can be useful for proper ID, so also a close up of the bark.
The fruits of this tree are edible (mostly roasted), but I have been told that wood was used of these trees for poles (or fire wood logs). What they did in the past, was to cut down a large tree, and out of the roots many new shoots (small trunks) would grow. These new shoots are usually very straight and ideal for poles, and cut every ten years or so (also known as coppicing).
The Castanea genus is part of the Fagaceae family, which also includes oaks and beech (see wiki).
