Thank you for your question. The answer is no. You can't compel your neighbour to fell the tree as it's not causing any issues just now. In the future if it needs trimmed at your boundary you would be permitted to do so. If it interfered with light then again you could use take certain steps. However, and having been in practice for over 30 years, I can think of no remedy available to you just now. I hope that helps. Please leave a positive rating so that I am credited for my time.
