Your lease will likely contain a covenant about causing nuisance or annoyance to others in the building and it is normally the landlord who has the power to enforce the covenants in the lease although sometimes it can also be the leaseholder. However, it is unlikely that a court will evict a leaseholder for being noisy. So firstly, try to have a quiet word with your neighbour and if things don’t improve keep a record and ask your local authority to assist.
