That looks like golden privet to me.
I would check it thoroughly to make sure there's no nesting activity going on yet ... liif there is you'll haveto wait until autumn as it's strictly illegal to disturb nesting birds.
If it's all clear then cut it back ... clear any weeds out of the base (makings sure you don't disturb any hibernating hedgehogs ... they love hedge bottoms ... and give the hedge a feed of Fish Blood and Bone sprinkled around the root area according to the pack instructions. It'll soon leaf up again.
