Principally, these will be the requirements to keep the inside of the flat in good order, to pay (on time) a share of the costs of maintaining and running the building, to behave in a neighbourly manner and not to do certain things without the landlord’s consent, for example, make alterations or sublet. The landlord has an obligation to ensure that the leaseholder complies with such responsibilities for the good of all the other leaseholders. These rights and responsibilities will be set out in the lease.
