Commercial Lease Solicitors

Expert Commercial Lease Solicitors

A commercial lease can determine the financial and operational relationship between a landlord and tenant for many years.

Rent is only one part of that relationship.

Repair obligations, service charges, insurance, rent reviews, permitted use, alterations, assignment rights, break clauses and security of tenure can all have significant financial and practical consequences.

At Knights & Shah Solicitors, we advise commercial landlords, tenants, investors, property companies, developers and businesses on commercial leases across England.

We can assist with:

Our approach is to understand the commercial purpose of the lease and ensure that the legal documentation reflects the client's intended position.

Who We Advise

Commercial Landlords

We advise landlords granting new leases, acquiring tenanted investments and managing existing commercial tenants.

The landlord's objectives may include protecting the value of the property, preserving flexibility, maintaining appropriate tenant obligations and ensuring that the lease works effectively as an investment document.

Commercial Tenants

We advise businesses taking commercial premises and existing tenants dealing with renewals, assignments, alterations, expansion or exit.

For a tenant, the lease can represent a substantial long-term financial commitment.

Understanding the obligations before signing is therefore essential.

Property Investors

The terms of occupational leases can directly affect the value, income and marketability of an investment property.

We advise investors on lease documentation both when acquiring investments and throughout ownership.

Developers

Development projects may require agreements for lease, pre-lets and occupational arrangements before construction or refurbishment has completed.

Businesses and Corporate Occupiers

We advise businesses occupying offices, shops, warehouses, industrial premises and other commercial property.

New Commercial Leases

A commercial lease establishes the legal relationship between the landlord and tenant.

The terms should reflect the commercial agreement reached between the parties while addressing the practical issues that may arise throughout occupation.

A commercial lease can deal with matters including:

• Length of the term
• Rent

Rent payment dates

Rent-free periods

Rent reviews

Service charges

Repair

Insurance

Permitted use

Alterations

Assignment

Underletting

Sharing occupation

Access

Rights granted to the tenant

Rights reserved to the landlord

Signage

Compliance with laws

Break rights

Security of tenure

Reinstatement

Yielding up

Guarantees

Rent deposits

The importance of each provision depends upon the property and the client's commercial objectives.

Heads of Terms

Commercial lease negotiations often begin with heads of terms.

These record the principal commercial terms agreed in principle between landlord and tenant.

They may include:

• Property
• Parties

Lease term

Rent

Rent-free period

Rent review

Break options

Repairing obligations

Service charge arrangements

Insurance

Permitted use

Assignment and underletting

Alterations

Security of tenure

Rent deposit

Guarantor requirements

Conditions affecting completion

Heads of terms are commonly expressed to be subject to contract, but particular provisions may have separate legal effect depending upon their wording.

Early solicitor involvement can help identify issues before the parties become commercially committed to a structure that is difficult to document.

Agreements for Lease

Sometimes a lease cannot be granted immediately.

An agreement for lease can create a contractual obligation to grant and accept a lease once specified conditions have been satisfied.

This can be particularly relevant where:

A property is under construction

Refurbishment works are required

Planning conditions must be satisfied

Landlord works must be completed

Tenant works are required

Third-party consent is outstanding

A development is being pre-let

The agreement should clearly establish what must happen before the lease is completed and what happens if the conditions are not satisfied.

Commercial Leases for Landlords

A landlord granting a commercial lease needs to protect both the property and the long-term value of the investment.

We can advise landlords on:

Heads of terms

Drafting leases

Rent provisions

Rent reviews

Service charges

Repair obligations

Insurance

Permitted use

Alterations

Assignment and underletting

Guarantees

Rent deposits

Break clauses

Contracting out

Renewal rights

Licences

Surrenders

Variations

A well-structured lease should provide appropriate protection while remaining commercially workable.

Detailed landlord advice is available through our dedicated Leases for Landlords service.

Commercial Leases for Tenants

A commercial tenant should understand the legal and financial obligations being accepted before signing a lease.

Those obligations may continue for years and can extend significantly beyond payment of the headline rent.

We advise tenants on matters including:

• Lease term
• Rent
• Rent reviews
• Rent-free periods
• Service charges
• Repair liability
• Insurance contributions
• Permitted use
• Alterations
• Assignment
• Underletting
• Break clauses
• Security of tenure
• Reinstatement
• Yielding-up obligations
• Guarantees
• Rent deposits

We explain the practical effect of the proposed terms and identify provisions that may justify further negotiation.

Detailed tenant representation is available through our Leases for Tenants service.

Rent and Rent-Free Periods

The lease should clearly establish:

Initial rent

Payment dates

Payment mechanism

VAT treatment where applicable

Rent-free arrangements

Any stepped rent

Interest on late payment

Rent review provisions

A rent-free period may be documented within the lease or separately depending upon the transaction.

Both parties should understand precisely when full rent becomes payable and whether other payments, such as service charges or insurance contributions, remain payable during the rent-free period.

Commercial Rent Reviews

Many longer commercial leases provide for the rent to be reviewed during the term.

The lease determines:

When the review occurs

How the new rent is calculated

What assumptions apply

What matters are disregarded

How disputes are resolved

An open-market rent review commonly seeks to determine the hypothetical market rent in accordance with assumptions and disregards contained in the lease.

The precise wording matters.

We advise landlords and tenants on the legal provisions governing rent reviews and associated documentation.

Detailed advice is available through our dedicated Rent Reviews service.

Repairing Obligations

Repair obligations can create substantial liabilities.

A lease may require the tenant to repair:

The interior

The structure

The exterior

Building services

Other parts of the premises

Alternatively, the landlord may undertake some or all of those works and recover relevant expenditure through a service charge.

A tenant considering a lease should understand whether its repairing obligation could require it to put premises into a better condition than they were in when the lease was granted.

Where appropriate, a schedule of condition may be negotiated to qualify repairing obligations.

The legal wording should be considered alongside advice from an appropriate building surveyor.

Service Charges

In multi-let commercial property, the landlord may provide services for the building or estate and recover expenditure from tenants.

The lease may address:

Services provided

Tenant's proportion

Management costs

Repair and maintenance

Common parts

Utilities

Security

Landscaping

Reserve or sinking funds

Major works

Accounting procedures

For landlords, appropriate service charge drafting can be important to the recoverability of expenditure.

For tenants, the provisions can create significant costs in addition to rent.

Insurance

Commercial leases commonly provide for the landlord to insure the building and recover the relevant premium from the tenant.

The lease may also address:

Insured risks

Uninsured risks

Rent suspension following damage

Reinstatement

Insurance proceeds

Termination where reinstatement does not occur

The allocation of risk should be understood by both parties.

Permitted Use

A commercial lease normally specifies how the tenant may use the premises.

The permitted-use clause should be considered alongside the tenant's actual business requirements.

An unnecessarily narrow use provision can reduce operational flexibility.

A landlord may, however, require appropriate restrictions to protect:

The property

Other occupiers

Tenant mix

Estate management

Investment value

The lease wording does not itself guarantee that the proposed use has all necessary planning or regulatory permissions.

Those issues should be investigated separately where relevant.

Alterations to Commercial Premises

Businesses often need to adapt premises to suit their operations.

The lease may distinguish between:

Structural alterations

Non-structural alterations

Internal alterations

External alterations

Installations

Signage

Some works may be prohibited while others may require landlord consent.

Where consent is required, a separate licence to alter may document the approved works and any reinstatement requirements.

Both landlord and tenant should establish the position before works begin.

Assignment of a Commercial Lease

Assignment transfers the tenant's leasehold interest to another party.

Whether assignment is permitted depends upon the lease.

HM Land Registry notes that most leases contain restrictions on assignment or underletting without landlord consent.

An assignment can involve:

Landlord consent

Licence to assign

Financial information concerning the proposed assignee

Rent deposit requirements

Guarantees

An Authorised Guarantee Agreement where legally appropriate

Registration requirements

The outgoing tenant should not assume that assignment automatically ends every possible liability connected with the lease.

Our dedicated Lease Assignments & Licences service deals with these transactions in greater depth.

Underletting Commercial Premises

A tenant may wish to sublet all or part of its premises.

Whether this is possible depends upon the lease.

GOV.UK confirms that subletting depends upon the lease terms and landlord permission may be required. The original tenant remains responsible for paying rent to its landlord even if the subtenant does not pay the tenant.

The transaction may require:

Landlord consent

Licence to underlet

Review of the proposed underlease

Compliance with conditions in the headlease

Consideration of permitted use

Rent provisions

Registration

Licences

Commercial landlords and tenants frequently require formal consent during the lease term.

This can include:

• Licence to assign
• Licence to underlet
• Licence to alter
• Licence for change of use
• Consent relating to occupation
• Other lease-specific permissions

A licence records the landlord's consent and the conditions attached to it.

The original lease should be reviewed carefully to establish whether consent is required and what conditions may apply.

Security of Tenure and the Landlord and Tenant Act 1954

Part II of the Landlord and Tenant Act 1954 provides qualifying business tenants with statutory security of tenure.

In broad terms, this can give a qualifying tenant a right to remain in occupation and seek a new tenancy when the contractual lease term ends, unless the tenancy has been validly contracted out or the landlord can establish a statutory ground of opposition.

The Law Commission confirms that most business tenants currently have renewal rights unless the parties validly agree before the tenancy is granted that those rights will not apply.

Whether a lease is protected can have major consequences for both landlord and tenant.

Contracting Out of the 1954 Act

A landlord and tenant may agree that qualifying security-of-tenure rights under the 1954 Act will not apply to the tenancy.

This is commonly known as contracting out.

Specific statutory formalities must be completed before the tenancy is entered into.

For the landlord, contracting out can provide greater certainty that possession can be recovered at the contractual end of the lease.

For the tenant, the consequence is significant: it will not ordinarily have the statutory right to a renewal tenancy at the end of the term.

The contracting-out position should therefore be considered when negotiating the lease rather than treated as a technical formality at completion.

Current 1954 Act Reform Position

The 1954 Act remains in force.

The Law Commission is currently reviewing the business-tenancy security-of-tenure regime. Its second consultation was published on 16 June 2026, with the consultation closing on 16 September 2026. The Commission's provisional approach retains the existing contracting-out model while considering reforms to how the regime operates.

Those proposals are not the current law merely because they are under consultation.

Our commercial lease advice is based upon the legislation in force at the relevant time, while monitoring developments affecting commercial landlords and tenants.

Commercial Lease Renewals

When a commercial lease approaches expiry, landlord and tenant should establish early whether it benefits from security of tenure under the 1954 Act.

Where the Act applies, statutory procedures can govern:

Termination of the existing tenancy

Requests for a new tenancy

Opposition to renewal

Timing

Interim rent

Terms of the renewal lease

Court proceedings where agreement cannot be reached

Where the parties agree terms, a renewal can often proceed without contested proceedings.

Where terms or the right to renew are disputed, specialist advice should be obtained promptly.

Our dedicated Lease Renewals & 1954 Act service covers this area in depth.

Break Clauses

A break clause allows a landlord, tenant or sometimes both parties to terminate a lease before the contractual expiry date.

The lease determines:

Who may exercise the break

When it may be exercised

The notice required

How notice must be served

Conditions that must be satisfied

GOV.UK confirms that break clauses may require notice and compliance with additional conditions such as payment obligations.

HM Land Registry likewise recognises that a fixed-term lease may contain a break option exercisable by notice and that conditions attached to the break may need to be satisfied.

Break clauses require careful review because the wording and procedural requirements can be important to whether the break takes effect.

Lease Surrenders

A surrender occurs where landlord and tenant agree to bring the lease to an end.

GOV.UK describes this as an agreement between landlord and tenant to end the lease early and notes the need for legal documentation evidencing that agreement.

A surrender may arise where:

A tenant wishes to exit early

A landlord wants possession for redevelopment

The parties negotiate a commercial exit

A new occupational arrangement is being created

Property-management strategy changes

The financial and legal terms of the surrender should be documented clearly.

Our dedicated Surrenders & Terminations service covers early lease exits in greater depth.

Lease Variations and Regears

Commercial circumstances can change during a lease.

Landlord and tenant may therefore agree to alter the existing arrangements.

A deed of variation or regear may deal with:

Lease term

Rent

Rent review

Break rights

Property extent

Permitted use

Repair obligations

Other commercial provisions

A lease regear can form part of a wider asset-management strategy.

The consequences should be considered carefully, particularly where a lender or superior landlord has an interest in the property.

Rent Deposits

A landlord may require a tenant to provide a rent deposit as security for its obligations.

A rent deposit deed may regulate:

Amount of the deposit

Circumstances in which the landlord may withdraw funds

Replenishment

Interest

Release of the deposit

Assignment

Insolvency-related matters

The terms should be considered alongside the lease.

Guarantees and Authorised Guarantee Agreements

A landlord may require additional security for tenant obligations.

Depending upon the transaction, this can involve a guarantor.

Assignments can also raise questions concerning Authorised Guarantee Agreements, under which an outgoing tenant may guarantee the performance of the incoming tenant in circumstances permitted by law.

The requirements should be considered in the context of the relevant lease and transaction rather than assumed to apply automatically.

Commercial Lease Due Diligence

Before entering into or acquiring a commercial lease, legal due diligence may involve reviewing:

Landlord's title

Property extent

Rights granted

Rights reserved

Restrictions

Searches

Planning information

Service arrangements

Existing documentation

Lease terms

Rent deposit requirements

Guarantees

Third-party consents

A tenant should also consider obtaining appropriate building and technical advice concerning the physical condition of the premises.

Legal due diligence does not replace a survey.

Commercial Lease Negotiations

Not every lease term should automatically be accepted simply because it appears in the landlord's first draft.

The appropriate negotiating position depends upon:

Property

Market

Bargaining strength

Lease length

Rent

Tenant covenant

Proposed use

Investment objectives

Commercial timetable

Potential areas for negotiation can include:

• Repair
• Service charges

Rent review

Break conditions

Assignment

Underletting

Alterations

Permitted use

Reinstatement

Guarantees

Rent deposits

Our role is to identify material legal and commercial issues and advise the client on the consequences of the proposed wording.

The Commercial Lease Process

Step 1 — Heads of Terms

The principal commercial terms are agreed or reviewed.

Step 2 — Property and Client Due Diligence

Relevant title information, searches and supporting documentation are obtained and reviewed.

Step 3 — Draft Lease

The landlord's solicitor normally prepares the first draft of the lease and associated documents.

Step 4 — Lease Review and Negotiation

The documentation is reviewed and amendments negotiated.

Step 5 — Additional Documentation

Rent deposits, guarantees, licences or other documents are agreed where required.

Step 6 — 1954 Act Position

Where relevant, security of tenure and any contracting-out arrangements are addressed.

Step 7 — Reporting

The material terms and obligations are explained before the client becomes committed.

Step 8 — Completion

The lease and associated documents are completed.

Step 9 — SDLT

Where required, the tenant's SDLT obligations are addressed.

Step 10 — Land Registry

Where registration is required, the relevant application is submitted to HM Land Registry.

Problems With Existing Commercial Leases

We can also advise where an existing lease presents practical difficulties.

Examples include:

• Unclear repair obligations
• Assignment restrictions
• Alteration restrictions
• Disagreement concerning permitted use
• Break-clause issues
• Renewal questions
• Surrender negotiations
• Service charge concerns

Rent review issues

Need for a deed of variation

Exit requirements

Where a matter becomes contentious, it can be referred to our Commercial & Property Litigation practice rather than duplicating dispute-resolution content within the transactional Commercial Property section.

Commercial Lease Disputes

Commercial lease disputes can concern:

Rent arrears

Service charges

Repair

Dilapidations

Breach of covenant

Forfeiture

Renewal

Possession

Alterations

Assignment

Break notices

Other lease obligations

These are contentious matters.

Our Commercial Property section is designed principally around transactional and advisory work.

Where a dispute arises, the matter can be handled through our Commercial Property Disputes service within Litigation.

This maintains a clear separation between transactional commercial property advice and contentious property litigation.

A Commercial Approach to Lease Advice

A commercial lease should work for the client's business or investment strategy.

For a landlord, we consider questions such as:

Does the lease protect the property appropriately?

Can relevant expenditure be recovered?

Does the lease preserve appropriate control over assignment and alterations?

Is the security-of-tenure position correct?

Could the lease affect future investment value or redevelopment?

For a tenant:

Can the premises be used for the intended business?

What will occupation actually cost beyond the headline rent?

How extensive are the repairing obligations?

Can the business assign or underlet if circumstances change?

Is there an effective exit route?

Does the tenant have renewal rights?

Our objective is to ensure that the legal documentation is understood in the context of the client's commercial objectives.
