Many landlords who let flats are leaseholders.
They may own the flat, arrange the tenancy, collect the rent and deal directly with the tenant. But they are still bound by another important document: the lease.
That lease sits above the tenancy agreement and can affect what the landlord is allowed to do with the property.
The key message is simple: leasehold landlords must comply with both the tenancy agreement and the lease. Ignoring the lease can create serious problems with the freeholder, managing agent, insurer, lender and tenant.
Why leasehold letting is different
A freehold landlord usually owns the whole property outright.
A leasehold landlord owns the right to occupy and use the flat for the term of the lease, subject to the lease terms.
That means a leasehold landlord is often dealing with two relationships at once:
- the relationship with the tenant under the tenancy agreement;
- the relationship with the freeholder or management company under the lease.
These two sets of rules need to work together.
If the tenancy promises something the lease does not allow, the landlord may have created a problem.
The lease comes first
The tenancy agreement cannot give the tenant rights the landlord does not have.
For example, if the lease prohibits short-term letting, the landlord should not grant a tenancy or licence that allows short stays.
If the lease restricts pets, alterations, flooring, use of balconies, business use or storage in common areas, the landlord should not ignore those restrictions when drafting the tenancy agreement.
The landlord can only pass on rights they actually have.
Consent to sublet
Some leases allow subletting.
Some prohibit it.
Some allow it only with written consent from the freeholder, landlord or management company.
Leasehold landlords should check the lease before letting.
They should look for clauses dealing with:
- underletting;
- subletting;
- sharing occupation;
- parting with possession;
- holiday letting;
- short-term letting;
- Airbnb-style use;
- company lets;
- HMOs;
- use of the flat as a private dwelling;
- consent requirements;
- registration of the tenancy;
- administration fees.
A landlord should not assume that because other flats are rented out, their own lease allows the same thing.
Long-term lets and short-term lets
A lease may treat long-term residential letting differently from short-term letting.
A standard residential tenancy of 6 or 12 months may be permitted, but holiday lets, serviced accommodation or short stays may be prohibited.
This is important because short-term letting can create more complaints, higher footfall, security issues, insurance concerns and potential breach of lease.
Landlords should not switch from a normal tenancy to short lets without checking the lease, mortgage, insurance, planning and local rules.
Registration requirements
Some leases require the leaseholder to notify the freeholder or managing agent when the flat is let.
This may involve:
- registering the tenancy;
- providing tenant details;
- giving a copy of the tenancy agreement;
- paying a registration fee;
- updating contact details;
- confirming the letting type;
- supplying an emergency contact.
Failure to register may be a breach of lease even where subletting itself is allowed.
Service charges
Leasehold landlords usually remain responsible for service charges.
The tenant may pay rent to the landlord, but the freeholder or managing agent will usually demand service charges from the leaseholder.
Service charges may cover:
- building insurance;
- communal cleaning;
- maintenance of common parts;
- gardening;
- lifts;
- management fees;
- repairs;
- reserve funds;
- major works;
- fire safety works;
- external decoration;
- roof repairs;
- communal electricity.
A landlord should not assume service charges can automatically be passed directly to the tenant.
If the landlord wants to recover any costs through rent, the rent needs to be set with those costs in mind.
Major works
Major works can cause major problems for leasehold landlords.
The landlord may receive large demands for building works, such as:
- roof repairs;
- cladding works;
- external decorations;
- window replacement;
- fire safety improvements;
- lift repairs;
- structural works;
- drainage works;
- communal area refurbishment.
These works may affect cash flow, profitability, mortgage planning and the tenant’s quiet enjoyment.
If works are likely to cause disruption, the landlord may need to communicate with the tenant clearly and manage expectations.
Ground rent
Ground rent may also remain payable by the leaseholder.
Although ground rent reforms have changed the position for many new leases, existing leases may still include ground rent obligations.
Leasehold landlords should keep records of ground rent demands and payments.
They should also understand any escalation clauses, because rising ground rent can affect saleability, mortgageability and investment value.
Building insurance
In many blocks of flats, the freeholder or management company arranges the buildings insurance.
The leaseholder pays their share through the service charge.
However, this does not mean the landlord can ignore insurance.
Leasehold landlords should check:
- what the block policy covers;
- what it excludes;
- whether landlord contents cover is needed;
- whether loss of rent cover is needed;
- whether landlord liability cover is needed;
- whether letting must be disclosed;
- whether short lets or HMOs are excluded;
- whether unoccupied periods affect cover;
- whether tenant use complies with the policy.
The block buildings policy may not protect the landlord from every letting-related risk.
Mortgage consent
A leasehold landlord should also check their mortgage position.
If the property was originally bought as a home, the lender may need to give consent to let.
If the property is already on a buy-to-let mortgage, the landlord still needs to comply with the lender’s conditions.
Mortgage conditions may restrict:
- short-term lets;
- company lets;
- HMOs;
- letting to family members;
- benefit-supported tenancies;
- student lets;
- holiday lets;
- subletting arrangements;
- tenancy length;
- occupation type.
A leasehold landlord needs the lease, mortgage and insurance to align.
Use as a private dwelling
Many leases require the flat to be used only as a private residential dwelling.
This may restrict business use, commercial use, short-term letting or other arrangements.
Landlords should be cautious where tenants want to:
- run a business from the flat;
- use the flat as serviced accommodation;
- sublet rooms;
- host paying guests;
- use the property as a company base;
- operate beauty, childcare or other services from the premises.
A tenancy agreement should make clear that the tenant must not use the property in a way that breaches the lease.
Pets
Pet clauses can be particularly difficult.
The landlord may be willing to consider pets, and rental reform is moving towards a more pet-friendly approach. But the lease may impose restrictions.
A lease may:
- prohibit pets entirely;
- require freeholder consent;
- allow only certain pets;
- prohibit animals that cause nuisance;
- restrict pets in common areas;
- allow the management company to withdraw permission.
Leasehold landlords should check the lease before responding to pet requests.
If freeholder consent is needed, the landlord should not promise permission before it is obtained.
Flooring
Flooring clauses are common in flats.
A lease may restrict hard flooring, require carpets, require underlay or prohibit changes that increase noise transmission.
This matters because noise complaints are one of the most common issues in blocks.
A landlord should check the lease before fitting laminate, wood or tiled flooring.
They should also make sure tenants do not remove carpets or install flooring without consent.
Alterations
Leasehold landlords should check alteration restrictions carefully.
The lease may require consent for:
- structural works;
- removing walls;
- changing windows;
- replacing doors;
- altering plumbing;
- changing heating systems;
- installing hard flooring;
- bathroom or kitchen changes;
- fitting satellite dishes;
- installing EV chargers;
- changing balconies;
- fitting air conditioning;
- external alterations.
A tenant should not be allowed to carry out alterations that the landlord cannot authorise.
Even landlord improvements may require consent.
Flat entrance doors
A flat entrance door may be part of the building’s fire safety strategy.
The lease may restrict replacement or alteration of the door.
A landlord should not allow tenants to fit extra locks, cat flaps, unsuitable door viewers, smart locks or other fittings without checking the lease and fire safety requirements.
A damaged or altered flat entrance door can affect the safety of the wider building.
Common parts
Tenants use common parts, but the landlord’s lease usually controls how those areas may be used.
Common parts may include:
- entrances;
- corridors;
- staircases;
- lifts;
- bin stores;
- communal gardens;
- parking areas;
- cycle stores;
- meter cupboards;
- roof spaces;
- balconies;
- shared courtyards.
Tenants should be told not to store items in common areas, obstruct escape routes, leave rubbish, cause nuisance or breach building rules.
The landlord may be responsible to the freeholder if the tenant breaches the lease.
Nuisance and noise
Most leases include nuisance clauses.
These may restrict noise, anti-social behaviour, nuisance, annoyance and disturbance to other residents.
If a tenant causes repeated problems, the freeholder or managing agent may complain to the leasehold landlord.
The landlord should take complaints seriously and keep records of action taken.
A tenant breach can become a landlord problem if it also amounts to breach of lease.
Refuse and recycling
Building rules may cover bins, recycling, bulky waste and collection points.
Tenants should receive clear instructions.
Problems may arise where tenants:
- leave rubbish in corridors;
- use the wrong bins;
- dump bulky waste;
- block bin stores;
- leave bags outside doors;
- ignore recycling rules;
- attract pests.
In blocks, poor waste management affects other residents and may trigger complaints.
Parking
Leasehold parking rights can be complex.
A flat may have:
- an allocated parking space;
- a permit scheme;
- visitor parking;
- no parking rights;
- restrictions on commercial vehicles;
- EV charging rules;
- garage restrictions;
- communal parking rules.
The tenancy should not promise parking unless the landlord has the right to provide it.
If permits are needed, the landlord should explain the process before the tenancy begins.
Balconies
Balconies are often subject to building rules.
Restrictions may cover:
- barbecues;
- smoking;
- storage;
- plants;
- screens;
- artificial grass;
- furniture;
- washing lines;
- heaters;
- gas cylinders;
- pets;
- noise;
- fire safety.
Landlords should pass balcony rules to tenants and keep a record that this has been done.
HMOs and shared occupation
A lease may restrict use as an HMO or shared house.
Even if the local authority would license the property, the lease may still prohibit or restrict that type of occupation.
Leasehold landlords should check before letting to unrelated sharers.
They should consider:
- lease restrictions;
- HMO licensing;
- planning rules;
- mortgage conditions;
- insurance cover;
- fire safety duties;
- building management rules;
- impact on other residents.
A flat in a block may not be suitable for HMO use simply because it has enough bedrooms.
Company lets
Company lets may also cause lease issues.
The lease may require occupation as a private residence by an individual household.
A company let may involve changing occupiers, employees, contractors or serviced accommodation style use.
Landlords should check whether company letting is permitted before agreeing terms.
They should also consider insurance, mortgage and management company requirements.
Short lets and serviced accommodation
Short lets can be especially risky in leasehold flats.
They may breach:
- lease use clauses;
- subletting restrictions;
- planning rules;
- mortgage conditions;
- insurance policy terms;
- building security rules;
- quiet enjoyment expectations of other residents.
Short lets may also create complaints about noise, security, waste, visitors and wear to common parts.
Landlords should not assume that short-term letting is simply another form of renting.
Passing lease obligations to tenants
A good tenancy agreement should require the tenant to comply with relevant lease obligations and building rules.
However, landlords should not rely only on a broad clause.
It is better to give tenants practical information about:
- parking;
- bins;
- pets;
- noise;
- flooring;
- balconies;
- common parts;
- fire safety;
- access arrangements;
- building security;
- managing agent contact points;
- emergency procedures;
- restrictions on alterations.
Tenants cannot follow rules they have never seen or been told about.
Managing agent communication
Leasehold landlords should keep good communication with the managing agent or freeholder.
They should make sure they receive:
- service charge demands;
- ground rent demands;
- building safety notices;
- fire safety updates;
- major works notices;
- insurance information;
- resident circulars;
- access requests;
- complaints about tenants;
- changes to building rules;
- consultation notices.
If the landlord lives away from the property, missed correspondence can quickly become expensive.
Tenant access for building works
Building works in blocks may require access to individual flats.
This can include:
- fire door inspections;
- window works;
- pipework;
- leak investigations;
- electrical risers;
- balcony inspections;
- structural surveys;
- roof access;
- external repairs;
- cladding inspections.
The landlord may need to coordinate access with the tenant.
The tenancy agreement should include appropriate access provisions, but notice and communication still matter.
Insurance claims and leaks
Leaks between flats are common.
A leasehold landlord should understand how claims are handled.
Questions may include:
- is the leak from inside the flat or common parts?
- does the block policy apply?
- is the tenant responsible?
- is there landlord contents damage?
- is there damage to another flat?
- who pays the excess?
- does the managing agent need to inspect?
- are emergency contractors required?
- has the insurer been notified?
Good records and prompt action are essential.
Selling or remortgaging
Lease compliance can affect sale and remortgage.
Problems may arise if:
- subletting consent was never obtained;
- service charges are in arrears;
- ground rent demands were ignored;
- alterations were carried out without consent;
- major works disputes are unresolved;
- building safety information is missing;
- insurance issues are unclear;
- the lease term is reducing;
- management company disputes exist.
A landlord may only discover these problems when trying to sell or refinance.
Records landlords should keep
Leasehold landlords should keep a dedicated leasehold property file.
This may include:
- the lease;
- tenancy agreement;
- subletting consent;
- tenancy registration documents;
- service charge demands;
- ground rent demands;
- payment records;
- building insurance summary;
- managing agent correspondence;
- major works notices;
- fire safety information;
- building safety updates;
- pet consents;
- alteration consents;
- parking permits;
- balcony rules;
- complaints and responses;
- tenant information issued.
Good records can prevent confusion later.
Common landlord mistakes
1. Not reading the lease
The tenancy agreement cannot override lease restrictions.
2. Assuming subletting is automatically allowed
Consent may be needed before the property is let.
3. Promising parking or pets without checking
The landlord can only offer what the lease allows.
4. Ignoring managing agent correspondence
Service charge, fire safety and major works letters can be important.
5. Allowing tenant alterations
Tenant changes may breach the lease.
6. Forgetting short-let restrictions
A lease may allow ordinary letting but prohibit holiday or serviced accommodation use.
7. Keeping poor records
Consent, demands, notices and building rules should be stored carefully.
Practical checklist for landlords
Leasehold landlords should:
- read the lease before letting;
- check subletting rules;
- obtain consent where required;
- register the tenancy if needed;
- check mortgage consent;
- check insurance cover;
- review service charges and ground rent;
- understand building rules;
- pass relevant rules to tenants;
- check pet, parking and balcony restrictions;
- prevent unauthorised alterations;
- keep common parts clear;
- respond to managing agent letters;
- keep leasehold documents in the property file;
- review the position before short lets, HMOs or company lets.
The key takeaway
Leasehold landlords need to think beyond the tenancy agreement.
The lease may control whether the flat can be let, how it can be used, what the tenant can do, what the landlord must pay and how the wider building is managed.
A landlord who ignores the lease may face complaints, costs, breach notices, insurance problems, mortgage issues and difficulties when selling or remortgaging.
The safest approach is to read the lease, check consent requirements, pass key rules to tenants and keep clear records.
For leasehold landlords, the tenancy agreement matters — but it is not the only contract that matters.
