Who is liable for a subtenant's breach of the head lease: the leaseholder, the landlord or the letting agent?

In England and Wales, the usual answer is that the leaseholder remains liable to the freeholder for breaches of the head lease, even where the immediate conduct is by a tenant, subtenant or other occupier. Scotland is different because long residential leases were largely barred or converted, and Northern Ireland still has old long leases but does not have the same residential consent-not-unreasonably-withheld override.

Can a freeholder take action against a leaseholder for their tenant's breach of the lease?

Yes: in England and Wales a freeholder can take action against the leaseholder for their tenant’s breach of the head lease, because the leaseholder is the person bound by the lease covenants and the statutory forfeiture route is aimed at the lessee, not the occupier. That covers a leaseholder’s tenant being granted a pet in breach of a no-pets clause: the freeholder’s claim is normally that the leaseholder has allowed or failed to prevent a breach of the head lease. The Law of Property Act 1925 says forfeiture is not enforceable “unless and until the lessor serves on the lessee a notice—”, and for a long residential lease the Commonhold and Leasehold Reform Act 2002 adds that the landlord “may not serve” that notice unless the breach is admitted or determined. LEASE puts the practical rule bluntly: “You are legally responsible for ensuring your tenants follow the rules in your lease.”

What can a freeholder do about a subtenant misusing the communal areas?

A freeholder in England and Wales should normally enforce communal-area misuse through the leaseholder, because the leaseholder is the party bound by the head lease and the freeholder usually has no direct lease covenant against the subtenant. If a subtenant keeps leaving belongings or rubbish in the communal hallway against fire-safety instructions, the useful leverage is a formal demand to the leaseholder to stop the breach, followed where necessary by a tribunal or court determination and then the section 146 process. A tribunal has stated the privity point in plain terms: a party could not enforce covenants against wrongdoers where “there is no evidence that he had any privity of contract with them.” A private freeholder also cannot simply use the Part 1 anti-social behaviour injunction route as a shortcut, because the 2014 Act says such an injunction “may be granted only on the application of—” specified bodies. In practice, managing agents write to the leaseholder because that is where the lease liability sits.

Is a managing agent liable if a flat is being sublet in breach of the head lease?

A managing agent is not automatically liable to the freeholder or residents merely because a leasehold flat is being sublet in breach of the head lease, but the agent can owe duties to its own landlord client once it is on notice and fails to act. The important distinction is who is owed the duty: the Shamsan no-duty line concerns duties to residents or third parties outside the agent’s contract chain, not the ordinary contractual and negligence duties an agent owes to the landlord who instructed it. A Court of Appeal commentary on Shamsan records that “There was no vicarious liability on the part of the respondent for any negligence on the part of the independent contractor or its employees,” and another summary says the managing agent is “the agent of the landlord” even where its costs are recovered through service charge. So if an agent placed and reference-checked a tenant, did not know about later short-let subletting, and had no inspection or monitoring duty, liability is unlikely; once on notice, silence becomes much harder to defend.

If a letting agent lets a leasehold flat without the freeholder's consent, who is exposed?

The letting agent is never a party to the head lease and cannot breach it, so lease liability sits with the leaseholder alone via forfeiture; but the agent is not shielded, because the freeholder can sue it directly in tort for procuring the breach and the landlord can sue it separately in negligence for the loss. In England and Wales, a leaseholder who lets without required freeholder consent is the party exposed under the lease: one tribunal determined that “the Respondent has sublet the Flat without the written consent of the Applicant.” If the lease restricts underletting without consent, section 19 of the Landlord and Tenant Act 1927 usually implies that consent is “not to be unreasonably withheld,” but the landlord still has to obtain it. Forfeiture still requires the Law of Property Act 1925 section 146 notice, and a long residential lease usually also needs admission or determination under section 168 first. A subtenant can be affected too, because the court may grant under-lessee relief only on terms it sets.
