Landlords who own leasehold flats can easily focus almost entirely on the agreement they have with their tenant.
But there is another contract that can be just as important: the landlord’s own lease.
A leaseholder who rents out a flat effectively sits between two sets of contractual obligations. The tenancy agreement regulates the relationship with the tenant, while the superior lease regulates the leaseholder’s relationship with the freeholder or superior landlord.
Those two documents do not always say the same thing.
A tenancy agreement cannot normally give a tenant rights that allow the leaseholder landlord to ignore restrictions contained in the superior lease. That is why landlords should understand their lease before granting a tenancy, agreeing changes with a tenant or allowing a different use of the property.
Does the lease actually allow you to let the property?
The first question is the most basic: does the lease permit subletting?
Long residential leases vary considerably.
A lease might:
- allow ordinary residential subletting;
- require the freeholder’s consent;
- require notification after a tenancy is granted;
- impose conditions on the type of tenancy;
- require registration of the tenancy;
- charge an administration fee; or
- prohibit certain forms of letting altogether.
Do not assume that because other flats in the building are rented, your own lease must permit it.
Check the wording applying to your particular property.
Consent may be required before the tenant moves in
Some leases require consent to underlet.
Where that applies, a landlord should deal with the requirement before granting possession rather than discovering the problem later.
Depending on the lease, the freeholder or managing agent may ask for information such as:
- the tenant’s details;
- a copy of the tenancy agreement;
- confirmation of the tenancy type;
- contact details for the leaseholder;
- an administration fee; or
- a formal notice of underletting.
Keep evidence that the required consent or notification has been obtained.
Your tenant can put you in breach of your lease
This is one of the most important points for leasehold landlords.
The freeholder’s contractual relationship is usually with you, not your tenant.
If your tenant behaves in a way prohibited by the superior lease, the freeholder may therefore pursue you as the leaseholder.
Common lease restrictions can cover:
- excessive noise;
- nuisance or disturbance;
- use of communal areas;
- parking;
- rubbish;
- satellite dishes;
- alterations;
- pets;
- short-term letting; and
- business activity.
Your tenancy agreement should therefore reflect relevant restrictions contained in the superior lease.
Otherwise, you could find yourself promising the tenant something that your own lease prohibits.
Pets are a good example
The post-May 2026 tenancy rules in England give tenants stronger rights to request permission to keep a pet.
But leasehold landlords have an additional issue to consider.
If the superior lease prohibits pets, or requires the freeholder’s permission, the landlord cannot simply ignore that restriction.
Where consent from a superior landlord is required, the leaseholder may need to seek it before deciding the tenant’s request.
This is why leasehold landlords should know what their lease says before a pet request arrives.
A tenancy clause cannot rewrite the superior lease.
Short-term letting can create an even bigger problem
A lease might permit residential subletting but prohibit short-term or holiday occupation.
This distinction is particularly important for landlords considering moving between conventional residential letting and platforms offering short stays.
Restrictions may refer to:
- minimum letting periods;
- use as a private residence;
- occupation by a single household;
- business use; or
- holiday accommodation.
A landlord should never assume that permission to grant a normal residential tenancy also gives permission to operate the property as a holiday let.
Mortgage and insurance conditions should also be checked separately.
Nuisance clauses matter
Blocks of flats commonly contain lease provisions designed to protect neighbours from unreasonable disturbance.
These can become particularly important where tenants cause:
- persistent noise;
- late-night parties;
- obstruction of communal areas;
- antisocial behaviour;
- inappropriate waste disposal; or
- parking problems.
The freeholder or managing agent may contact the leaseholder landlord and require action.
That makes good tenancy drafting and good management important.
Where appropriate, tenants should be made aware of building rules affecting their occupation.
Communal areas are not part of the landlord’s private kingdom
Leasehold landlords also need to remember that hallways, lifts, stairwells, gardens, parking areas and other communal spaces may be controlled by the freeholder or management company.
The landlord may have limited rights over these areas.
Tenants should not automatically be promised:
- particular parking spaces;
- use of storage areas;
- permission to leave bicycles in communal areas;
- permission to install equipment externally; or
- unrestricted use of shared facilities
unless the lease actually gives the landlord those rights.
Alterations can create problems
Tenants sometimes request changes to rented accommodation.
These might include:
- fitting a satellite dish;
- installing an EV charger;
- changing flooring;
- installing security equipment;
- fixing items to external walls; or
- making accessibility adaptations.
The landlord may be willing to agree, but the superior lease might require separate consent from the freeholder.
Check before saying yes.
Flooring clauses are particularly easy to overlook
Some leases contain restrictions on hard flooring because of noise transmission between flats.
A landlord replacing carpet with laminate or allowing a tenant to do so could therefore create a breach even though the change appears relatively minor.
Before refurbishing a leasehold rental property, check whether the lease requires particular floor coverings or consent for alterations.
Insurance can involve several layers
In many blocks, the freeholder arranges buildings insurance and recovers the cost through the service charge.
That does not necessarily provide all the protection a landlord needs.
Leasehold landlords should understand:
- what the block policy covers;
- what it excludes;
- whether letting must be disclosed;
- whether tenant-related risks are included; and
- what additional landlord insurance is required.
Contents, liability, loss of rent and other landlord-specific risks may require separate cover.
Do not assume that paying towards a building insurance policy automatically means your rental activity is fully insured.
Service charges remain the leaseholder’s responsibility
A landlord may include certain costs when calculating the economics of the tenancy, but liability to the freeholder remains governed by the lease.
Service charges can include contributions towards:
- repairs;
- maintenance;
- cleaning;
- insurance;
- management;
- lifts;
- communal lighting;
- gardens; and
- major works.
A tenant failing to pay rent does not remove the leaseholder’s obligation to pay legitimate service charges to the freeholder.
For landlords assessing the profitability of a flat, these costs need to be included alongside mortgage payments, insurance, maintenance and taxation.
Watch for major works
Leasehold properties can sometimes generate significant unexpected expenditure.
Roof replacement, external repairs, lift works, structural repairs or other major projects can result in substantial bills.
Landlords should therefore read correspondence from managing agents rather than treating service-charge letters as routine paperwork.
If major works are being proposed, they may affect decisions about whether to:
- retain the property;
- refinance;
- improve it;
- increase financial reserves; or
- sell.
What happens if the lease is breached?
Ignoring the superior lease can have serious consequences.
The freeholder may initially demand that the breach stops.
Depending on the circumstances and wording of the lease, disputes can escalate into claims for costs, injunction proceedings or ultimately action concerning the lease itself.
Forfeiture of a residential long lease is subject to substantial legal protections and procedural requirements, so it is not something a freeholder can simply impose overnight.
Nevertheless, landlords should not treat lease breaches casually.
A relatively small tenancy-management problem can become an expensive leasehold dispute.
Check the lease when changing managing agent
Where a letting agent manages the tenancy, make sure the agent knows about relevant restrictions.
Give them information concerning:
- pets;
- parking;
- communal areas;
- subletting requirements;
- alterations;
- nuisance provisions; and
- building regulations.
An agent cannot comply with restrictions they have never been told about.
But appointing an agent does not make the leaseholder’s obligations disappear.
Selling does not make leasehold paperwork less important
Landlords thinking about selling should make sure their leasehold records are complete.
A prospective buyer or their solicitor may want information relating to:
- the lease;
- service charges;
- ground rent where applicable;
- building insurance;
- planned major works;
- disputes;
- licences or consents;
- managing agents; and
- the existing tenancy.
Problems that were ignored during ownership can emerge during conveyancing and delay a sale.
Build a leasehold landlord file
Every leasehold landlord should consider keeping a separate property file containing:
- the complete lease;
- any deeds varying the lease;
- consent to sublet;
- notices of underletting;
- management company correspondence;
- service-charge statements;
- building insurance information;
- major-works notices;
- building regulations supplied to tenants; and
- records of any permissions obtained.
Keep this alongside the normal tenancy compliance file rather than relying on your solicitor, managing agent or freeholder to produce documents years later.
One property, two important agreements
The tenancy agreement governs what happens between landlord and tenant.
The superior lease determines what the leaseholder is entitled — and required — to do with the property.
Successful management of a leasehold rental requires compliance with both.
Before granting a tenancy, changing how the property is used, approving a pet, authorising alterations or moving into short-term letting, ask one additional question:
What does my lease say?
That simple check can prevent a tenancy decision from becoming a much larger leasehold problem.
