Commercial Lease Solicitors for Landlords
Strategic commercial lease advice for landlords, investors and property owners. From heads of terms and new leases to renewals, licences, assignments and surrenders, we protect your property, income and long-term investment position.
Expert Commercial Lease Advice for Landlords
A commercial lease is one of the most important documents governing an income-producing property.
For a landlord, the lease determines considerably more than the rent payable by the tenant. It can regulate repair, service charges, insurance, alterations, assignment, underletting, permitted use, rent reviews, break rights, security of tenure and the condition in which the premises must ultimately be returned.
Poorly structured provisions can create problems that remain with the property for years and may affect rental income, management flexibility, refinancing and future sale.
At Knights & Shah Solicitors, we advise commercial landlords, property investors, developers, property companies and portfolio owners on commercial leases across England.
We can assist with:
- Heads of terms
- New commercial leases
- Agreements for lease
- Lease negotiations
- Rent deposits
- Guarantees
- Rent reviews
- Lease renewals
- Landlord and Tenant Act 1954 matters
- Contracting out of the 1954 Act
- Break clauses
- Lease assignments
- Licences to assign
- Underletting
- Licences to underlet
- Licences to alter
- Changes of use
- Deeds of variation
- Lease regears
- Surrenders

- Ongoing commercial property management documentation
Our approach is to understand the landlord's commercial objectives and ensure that the lease provides an appropriate legal framework for the property and investment.
Who We Advise
Individual Commercial Landlords
We advise individual owners letting offices, shops, industrial units, warehouses and other commercial premises.
Property Investors
For investors, occupational leases can directly affect the income and capital value of an asset.
We advise on lease structures both when investments are acquired and throughout the ownership lifecycle.
Property Companies and SPVs
We advise companies holding commercial property through corporate or special-purpose structures.
Portfolio Landlords
Clients with several commercial properties may require consistent but property-specific lease documentation across their portfolio.
Developers
We advise developers granting occupational leases and pre-lets as part of completed or ongoing developments.
Mixed-Use Property Owners
Where buildings contain different forms of occupation, careful consideration may be required to ensure that rights, services, insurance and management provisions work together appropriately.
Granting a New Commercial Lease
A landlord granting a new lease should consider both the immediate commercial agreement and the long-term implications for the property.
A commercial lease may need to address:
- The premises being let
- Lease term
- Rent
- Rent payment dates
- Rent-free periods
- Rent reviews
- VAT where applicable
- Service charges
- Repairing obligations
- Insurance
- Permitted use
- Alterations
- Assignment
- Underletting
- Sharing occupation
- Access rights
- Rights reserved to the landlord
- Rights granted to the tenant
- Signage
- Compliance obligations
- Break rights
- Security of tenure
- Reinstatement
- Yielding up
- Rent deposits
- Guarantees
The lease should reflect the individual property and transaction rather than simply reproducing a standard document without considering how the building will actually operate.
Heads of Terms for Commercial Landlords
Heads of terms usually record the principal commercial deal agreed between landlord and prospective tenant before the full lease is negotiated.
They may cover:
- Property
- Parties
- Lease length
- Rent
- Rent-free period
- Rent review
- Break options
- Repair
- Service charges
- Insurance
- Permitted use
- Alterations
- Assignment and underletting
- Security of tenure
- Rent deposit
- Guarantor requirements
- Landlord works
- Tenant works
Although heads of terms are commonly expressed to be subject to contract, getting the structure right at this stage can make the subsequent lease negotiation considerably more efficient.
Early legal input can also identify terms that may create unintended consequences for the landlord later.
Protecting the Landlord's Investment
For an investment landlord, the occupational lease forms part of the investment asset.
The quality of that lease can affect:
- Rental income
- Recoverability of property expenditure
- Future rent reviews
- Tenant flexibility
- Landlord control
- Financing
- Marketability
- Redevelopment options
- Future disposal
A prospective buyer or lender may scrutinise the lease when carrying out due diligence.
Lease drafting should therefore consider not only the current tenant relationship but also how the document may be viewed by future investors and lenders.
Rent Provisions
The lease should clearly establish the tenant's payment obligations.
Depending upon the transaction, this can include:
- Principal rent
- Payment dates
- Payment in advance
- VAT
- Interest on late payment
- Insurance rent
- Service charge
- Other sums reserved as rent or otherwise payable under the lease
- Rent-free periods
- Stepped rent arrangements
Care should be taken to ensure that any incentives agreed commercially are properly reflected in the transaction documents.
Rent-Free Periods and Tenant Incentives
Landlords may offer incentives to secure a tenant.
These can include:
- Rent-free periods
- Reduced initial rent
- Contributions towards fit-out
- Other concessions
- The legal documentation should make clear:
How long the incentive lasts
Which payments are affected
When full rent commences
Whether service charge or insurance remains payable
Whether any conditions apply
Where an incentive is documented in a side letter, its relationship with the lease should be carefully considered.
Commercial Rent Reviews
Rent review provisions can be important to the long-term income generated by an investment property.
The lease should establish:
- Review dates
- Review mechanism
- Assumptions
- Disregards
- Valuation date
- Dispute procedure
- Treatment of delayed reviews
The wording can materially affect the operation of a future review.
Our dedicated Rent Reviews service provides more detailed advice where a rent review becomes due or requires formal documentation.
Repairing Obligations
Repair provisions determine responsibility for maintaining the premises.
Depending upon the property, the lease may require the tenant to repair:
- Interior
- Exterior
- Structure
- Services
- Fixtures
- Specific parts of the premises
In a multi-let building, the landlord may retain responsibility for structural and common areas while recovering appropriate expenditure through the service charge.
GOV.UK guidance confirms that responsibility for repairs and maintenance in business premises is substantially governed by the lease.
For landlords, the drafting should clearly allocate responsibility and work effectively with the service-charge provisions.
Schedules of Condition
A prospective tenant may seek to limit its repairing obligations by reference to a schedule of condition.
This records the physical condition of the premises at or around the beginning of the lease.
Whether a landlord should agree to such a limitation depends upon:
- Property condition
- Lease length
- Proposed rent
- Nature of the premises
- Commercial negotiations
- Investment objectives
Where a schedule is agreed, the relationship between it and the repairing covenant needs to be drafted carefully.
A surveyor should usually prepare the technical schedule; our role is to ensure that its legal effect is appropriately reflected in the lease.
Service Charges
Service charge provisions are particularly important for landlords of multi-let properties.
A landlord may be responsible for maintaining and managing:
- Structure
- Roof
- Common areas
- Accessways
- Lifts
- Mechanical systems
- Security
- Landscaping
- Cleaning
- Lighting
- Estate roads
- Shared facilities
The lease should establish the contractual mechanism through which appropriate expenditure can be recovered from tenants.
This may include provisions dealing with:
- Services provided
- Tenant’s proportion
- Management costs
- Budgets
- Accounts
- Balancing payments
- Reserve funds where appropriate
- Major expenditure
- Excluded costs
Weak or inconsistent drafting can leave the landlord responsible for expenditure that cannot readily be recovered from occupiers.
Insurance
Commercial landlords frequently insure the building and recover the appropriate cost from tenants.
The lease may therefore need to address:
- Insured risks
- Insurance premiums
- Tenant contributions
- Excesses
- Rent suspension
- Reinstatement
- Uninsured risks
- Termination following serious damage
The insurance provisions should operate consistently with the repairing and service-charge provisions.
Permitted Use
The permitted-use clause controls the contractual activities the tenant may conduct from the premises.
For a landlord, the provision can be important in protecting:
- Investment value
- Tenant mix
- Other occupiers
- Estate management
- Building character
- Future letting flexibility
At the same time, a provision that is unnecessarily restrictive may make premises less attractive to tenants or potentially affect future assignment.
The appropriate wording therefore depends upon the property and commercial strategy.
Alterations
A landlord will generally want appropriate control over physical changes made by a tenant.
The lease may distinguish between:
- Structural alterations
- Non-structural alterations
- Internal alterations
- External alterations
- Installations
- Signage
Some alterations may be prohibited while others may require landlord consent.
Where consent is given, the parties may enter into a licence to alter recording:
- Approved works
- Plans and specifications
- Conditions
- Contractor requirements
- Reinstatement obligations
- Professional costs
- Other protections
The tenant should obtain required consent before carrying out works.
Assignment of Commercial Leases
A tenant may wish to transfer its lease to another business.
This is known as an assignment.
The lease determines whether assignment is permitted and what conditions apply.
For a landlord, an assignment can require consideration of:
- Proposed assignee
- Financial covenant
- References
- Existing breaches
- Rent arrears
- Rent deposit
- Guarantor requirements
- Authorised Guarantee Agreement
- Licence to assign
- Registration requirements
GOV.UK confirms that whether a business tenant can transfer its lease depends upon the lease and that landlord permission may be required.
Detailed advice is provided through our Lease Assignments & Licences service.
Authorised Guarantee Agreements
In appropriate circumstances, a landlord may require an outgoing tenant to enter into an Authorised Guarantee Agreement (AGA) in connection with an assignment.
An AGA can require the outgoing tenant to guarantee the obligations of the incoming tenant.
Whether an AGA can properly be required depends upon the lease, circumstances and applicable statutory framework.
It should not be treated as an automatic requirement in every assignment.
Where relevant, we advise landlords on whether an AGA can be required and prepare the appropriate documentation.
Underletting
A tenant may seek permission to sublet all or part of the premises.
Whether this is permitted depends upon the lease.
GOV.UK confirms that subletting is governed by the lease terms and landlord permission may be required. The original tenant remains responsible for its rent obligations to the landlord.
For landlords, relevant considerations may include:
- Identity of the proposed undertenant
- Terms of the proposed underlease
- Rent
- Permitted use
- Length of term
- Security of tenure
- Consistency with the headlease
- Effect on property management
Consent may be documented through a licence to underlet.
Licences to Assign, Underlet and Alter
Landlords frequently need to consider tenant applications for consent during the lease term.
These may include:
- Licence to assign
- Licence to underlet
- Licence to alter
- Consent to change use
- Consent relating to occupation
The starting point is the existing lease.
We review the relevant provisions, advise on the landlord's legal position and prepare or negotiate the appropriate documentation.
Rent Deposits
A landlord may require a rent deposit as security for tenant obligations.
A rent deposit deed can regulate:
- Amount held
- Circumstances allowing withdrawal
- Replenishment
- Interest
- Holding arrangements
- Release
- Assignment
- Insolvency-related circumstances
The appropriate amount and terms depend upon the transaction and commercial agreement.
Rent deposit arrangements should be considered alongside any separate guarantee.
Guarantors
A landlord may require a guarantor where additional security is considered appropriate.
This may arise where:
- The tenant is newly incorporated
- The tenant has limited trading history
- A parent company is supporting a subsidiary
- Additional covenant strength is commercially required
Guarantee provisions should clearly establish the scope and duration of the obligations being undertaken.
Landlord and Tenant Act 1954
Part II of the Landlord and Tenant Act 1954 remains central to many commercial leases.
Most qualifying business tenants currently benefit from security of tenure unless the tenancy is outside the statutory regime or the parties validly contract out before the tenancy is granted. Security of tenure can give a qualifying tenant a right to seek a new tenancy when its existing tenancy would otherwise end.
For landlords, this can be particularly important where future plans include:
- Redevelopment
- Reoccupation
- Reletting
- Sale
- Reconfiguration of the property
The security-of-tenure position should therefore be considered before the lease is completed, not simply when it approaches expiry.
Contracting Out of the 1954 Act
A landlord and tenant can agree, in appropriate circumstances and by following the required statutory process before the lease is granted, that the tenant will not receive the relevant statutory renewal protection.
This is commonly called contracting out.
For a landlord, a contracted-out lease can provide greater certainty over recovering possession when the contractual term expires.
For the tenant, the consequence is significant because it will not ordinarily have the statutory right to renew under the 1954 Act.
The Law Commission confirms that the existing contracting-out model remains the current framework. Its ongoing reform project has provisionally proposed retaining that model while considering changes to its operation. Those proposals are not yet law.
Lease Renewals
Where a tenant occupies under a lease protected by the 1954 Act, the expiry of the contractual term does not necessarily mean the landlord automatically recovers possession.
The statutory renewal regime may apply.
A landlord considering renewal should assess:
- Whether the tenancy is protected
- Whether a new tenancy is commercially desirable
- Proposed rent
- Proposed term
- Other renewal terms
- Future redevelopment plans
- Whether any statutory ground of opposition may apply
- Relevant procedural deadlines
Government guidance on renewing and ending business leases was updated on 30 July 2026.
Detailed advice is provided through our Lease Renewals & 1954 Act service.
Current 1954 Act Reform Position
The 1954 Act remains in force.
The Law Commission published its second consultation on reform of the business-tenancy regime on 16 June 2026, with the consultation closing on 16 September 2026.
Its provisional work includes possible reforms concerning contracting out, renewal tenancy terms, interim rent, grounds of opposition and dispute resolution. It has provisionally concluded that the existing contracting-out model should remain.
These are reform proposals and consultation questions, not changes currently in force.
Knights & Shah Solicitors advises landlords according to the law applicable at the relevant time.
Break Clauses for Landlords
A break clause can allow a landlord to terminate a lease before the contractual expiry date where the lease gives the landlord that right.
The provision should specify:
- When the break can be exercised
- Notice required
- Method of service
- Conditions attached to the break
- Break clauses can be strategically important where a landlord anticipates:
- Redevelopment
- Reconfiguration
- Sale
- Reoccupation
- Wider estate management
The wording should be considered carefully when the lease is first negotiated rather than only when the landlord later wishes to exercise the right.
Deeds of Variation
Commercial circumstances may change after a lease has been granted.
Landlord and tenant may agree to vary provisions relating to:
- Rent
- Term
- Break clauses
- Property extent
- Permitted use
- Repair
- Service charges
- Other lease obligations
A variation should be properly documented.
The effect on lenders, superior landlords, guarantors and other interested parties may also need consideration.
Lease Regears
A lease regear involves renegotiating existing lease terms during the contractual term.
This may involve:
- Extending the lease
- Removing or changing break rights
- Adjusting rent
- Changing rent-review provisions
- Altering repairing obligations
- Varying other commercial terms
For an investment landlord, a regear may form part of a wider asset-management strategy.
The effect on investment value, financing and future disposal should be considered alongside the immediate commercial agreement.
Lease Surrenders
A landlord and tenant may agree to terminate a lease early through surrender.
GOV.UK describes surrender as an agreement between landlord and tenant to bring the lease to an end early and confirms that legal documentation should evidence the arrangement.
A landlord might agree a surrender because:
- Redevelopment is planned
- A replacement tenant is available
- The property is being sold
- The tenant wants to leave
- A wider portfolio strategy requires vacant possession
- Terms may need to address:
- Surrender date
- Payments
- Rent arrears
- Service charges
- Repair
- Dilapidations
- Reinstatement
- Vacant possession
- Rent deposits
- Guarantees
Our Surrenders & Terminations service deals with commercial lease exits in greater detail.
End-of-Lease Condition and Dilapidations
The condition in which premises must be returned can have significant financial consequences.
Depending upon the lease, tenant obligations may concern:
- Repair
- Decoration
- Removal of alterations
- Reinstatement
- Removal of fixtures
- Yielding up
- Vacant possession
GOV.UK notes that business tenants may have obligations concerning repairs when leaving and refers to those end-of-lease repair liabilities as dilapidations.
Landlords should consider lease wording and the physical condition of the premises before expiry and obtain specialist surveying advice where appropriate.
Commercial Lease Registration
Certain commercial leases must be registered at HM Land Registry.
Current HM Land Registry guidance confirms that many business leases fall within compulsory registration requirements and, in broad terms, leases granted for a term of more than seven years are among those requiring registration.
Registration requirements depend upon the transaction and lease.
Where the tenant is responsible for registration, landlords should nevertheless ensure that the documentation has been completed correctly and that any relevant title requirements are addressed.
Landlord Consent and Property Finance
A landlord's own lender may have rights affecting the granting or variation of commercial leases.
Depending upon the financing arrangements, lender consent may be required for matters such as:
- Granting a lease
- Varying a lease
- Accepting a surrender
- Changing significant lease terms
The registered title and finance documentation should therefore be considered before completing a transaction where lender consent may be relevant.
Managing a Multi-Let Commercial Property
Multi-let buildings require leases that operate coherently together.
The landlord may need to manage:
- Common parts
- Building services
- Estate roads
- Shared access
- Insurance
- Repairs
- Service charges
- Tenant alterations
- Signage
- Parking
- Use restrictions
Inconsistent lease drafting can make future management difficult.
Where possible, landlords should maintain an organised approach to occupational documentation across the building or portfolio while allowing for property-specific commercial terms.
Preparing Commercial Property for Investment Sale
The occupational documentation may be scrutinised closely when an investment property is sold.
A prospective purchaser may review:
- Leases
- Rent deposits
- Guarantees
- Licences
- Deeds of variation
- Side letters
- Rent review memoranda
- Service charge information
- Existing disputes
- Tenant arrears
- Security-of-tenure documentation
Keeping a complete and organised lease record can therefore make future due diligence considerably more efficient.
Our Commercial Property Investment and Acquisitions & Disposals services deal with investment transactions in greater depth.
Common Commercial Lease Problems for Landlords
Problems can arise where:
- The lease does not clearly define the premises
- Repair provisions are inadequate
- Service charges cannot be recovered as expected
- Tenant alterations are undocumented
- Rent reviews have not been documented
- Side letters alter the apparent lease position
- Assignments occur without proper documentation
- Guarantees or rent deposits are missing
- Security-of-tenure documentation is defective or unclear
- Break provisions do not reflect the landlord’s long-term strategy
- Property-management documents are incomplete

A Commercial Approach to Landlord Lease Advice
A landlord needs more than a technically valid lease.
The lease should support the property's commercial strategy.
We therefore consider questions such as:
Does the lease protect the landlord's rental income?
Can appropriate property expenditure be recovered?
Are repairing obligations sufficiently clear?
Does the landlord retain appropriate control over alterations and assignment?
Does the lease preserve flexibility for future redevelopment?
Is the 1954 Act position appropriate?
Will the occupational documentation withstand due diligence by a future buyer or lender?
Could the lease create an avoidable problem when the property is refinanced or sold?
Our objective is to create and maintain occupational documentation that works throughout the investment lifecycle.

Commercial Lease FAQs for Landlords
What should a commercial landlord include in a lease?
The appropriate provisions depend upon the property and transaction, but commonly address rent, term, repair, service charges, insurance, use, alterations, assignment, underletting, break rights and the security-of-tenure position.
Should I instruct a solicitor before agreeing heads of terms?
Early legal involvement can be useful because heads of terms establish the commercial structure that the solicitors will later document. Identifying legal issues early may avoid unnecessary renegotiation.
Should a commercial lease be protected by the Landlord and Tenant Act 1954?
That is a commercial and legal decision depending upon the circumstances. Qualifying business tenants generally benefit from statutory renewal rights unless the tenancy falls outside the regime or the parties validly contract out before the lease is granted.
Can I contract a commercial lease out of the 1954 Act?
In appropriate circumstances, yes. The required statutory procedure must be followed before the tenancy is entered into. Contracting out means the tenant will not ordinarily have the relevant statutory renewal right at the end of the term.
Can I stop my commercial tenant assigning the lease?
The answer depends upon the lease terms and applicable law. Commercial leases commonly regulate assignment and may require landlord consent subject to specified conditions. The actual lease should be reviewed before responding to an assignment request.
Can I require a rent deposit?
A landlord can negotiate a rent deposit as part of the commercial terms. The amount and circumstances in which it can be used or released should be recorded in an appropriate rent deposit deed.
Can I require a guarantor?
A guarantee may form part of the negotiated security package, depending upon the tenant and transaction. The documentation should clearly establish the guarantor's obligations.
Who is responsible for repairs to commercial premises?
This depends substantially upon the lease. GOV.UK guidance confirms that business leases should state responsibility for repairs and maintenance.
Can I recover service charges from my commercial tenant?
The ability to recover particular expenditure depends upon the contractual provisions of the lease. Clear service-charge drafting is therefore important.
Can I refuse alterations?
The answer depends upon the lease, the type of alteration proposed and the applicable legal framework. The lease should be reviewed before a landlord grants or refuses consent.
What happens when a protected business lease expires?
Where Part II of the 1954 Act applies, expiry of the contractual term does not necessarily end the tenant's occupation. Statutory procedures govern renewal and termination.
Can a commercial landlord end a lease early?
Potentially, where the lease contains an exercisable landlord break right, the parties agree a surrender, or another lawful route is available. The correct mechanism depends upon the lease and circumstances.
Can you advise landlords with several commercial properties?
Yes. We can advise on individual leases as well as ongoing lease documentation and transactions across commercial property portfolios.
Can you deal with a dispute with my commercial tenant?
Yes. Where a matter becomes contentious, it can be handled through our Commercial & Property Litigation practice.
