Preventing Commercial Property Disputes in the UK: A Practical Checklist

Disputes often arise, not from major legal issues, but from unclear lease obligations, poor communication and inadequate documentation.  The most common disputes between commercial landlords and tenants include:  

• Rent arrears;  
• Service charge disputes;  
• Dilapidations claims;  
• Break clause disputes;  
• Lease renewal disputes;  
• Repair obligations;  
• Unlawful alterations;  
• Forfeiture proceedings.  

This checklist highlights the key arears commercial landlords and tenants should address to minimise legal risk and maintain effective relationships.  

Please note, this checklist does not constitute formal legal advice.  

For Commercial Landlords 

1) Ensure lease terms are clear and up to date 

Before granting a lease, ensure the agreement clearly addresses the following:  

• Rent review provisions;  
• Repair obligations;  
• Service charges;  
• Insurance responsibilities;  
• Break clauses;  
• Permitted use;  
• Alterations; and 
• Sub-letting rights.  

Ambiguous drafting is one of the most common causes of commercial lease disputes. Ensuring that all lease clauses are clearly defined will head off a large proportion of potential disputes at the very beginning.  

2) Verify the financial strength of the potential tenant 

Before entering into a lease, conduct adequate financial due diligence. Review the tenant’s trading history and assess the financial strength of any potential guarantor.  

A Rent Deposit Deed and deposit can usually protect against rental arrears. As rent is paid quarterly, three months deposit is usually a good starting point. 

Continue to monitor the status of any rent arrears or payment defaults. Ensure that the rental arrears don’t reach the level of any deposit you hold.  

Monitor insolvency filings and any company accounts to ensure that the tenant is not in financial difficulties.  

3) Document property condition before occupation 

Prior to entering into a new lease, prepare a detailed schedule of condition which includes photographs. Surveyors will be able to prepare these for you, or you can do it yourself. Undertake an inspection report right before the tenant takes possession. It is extremely helpful for this to be exhibited to the lease before signing, in order that both parties are in agreement.  

The presence of a detailed schedule of condition can significantly reduce disputes relating to repair obligations, dilapidations and property damage at lease expiry.  

4) Manage service charges transparently 

Landlords should provide clear service charge budgets and maintain accurate records. Retain all invoices for work undertaken and/or services provided.  

Landlords should review the lease clause carefully and only seek to recover costs permitted under the lease.  

Poor service charge management is a major source of landlord-tenant conflict.  

5) Maintain compliance with safety and regulatory obligations 

Ensure compliance with your obligations under:  

• Fire safety requirements;  
• Asbestos obligations;  
• Building regulations;  
• Insurance requirements; and 
• Energy efficiency standards.  

Landlords should maintain inspection records, risk assessments and compliance certificates.  

6) Monitor rent arrears and lease breaches early 

Address issues promptly if your tenant:  

• Falls into rental arrears; 
• Breaches lease clauses; 
• Fails to repair in accordance with the lease terms; or
• Permits unlawful occupation 

Delays in enforcement can weaken your position as a landlord and you may inadvertently waive your right to forfeit the lease.  

7) Follow proper notice procedures 

Commercial leases often contain strict notice requirements.  

Ensure that all notices, particularly those relating to rent reviews, break clauses, forfeiture, lease renewal and breaches of the lease are served correctly and within required timeframes.  

Incorrect notices, or notices that have been served incorrectly, can lead to entirely avoidable litigation.  

8) Understand security of tenure obligations 

Landlords should confirm whether leases fall within the protections of the Landlord and Tenant Act 1954.  

If you are contracting out of security of tenure you should ensure that statutory procedures are followed carefully and retain all supporting documentation.  

For Commercial Tenants 

1) Review lease obligations carefully before signing 

As a tenant, you should fully understand your repair liabilities, rent review mechanisms, service charge obligations, reinstatement obligations and break clause conditions.  

You do not want any unexpected lease liabilities arising from an inadequate legal review at the outset.   

2) Negotiate a schedule of condition 

Where possible you should limit your repair obligations by attaching a schedule of condition to the lease. This is particularly the case in older buildings or short-term leases.  

A detailed schedule of condition can significantly reduce your dilapidations exposure at the expiry of the lease.  

3) Monitor service charges closely 

As a tenant you should review the annual service charge accounts carefully and request supporting documentation where necessary. 

If you wish to challenge unreasonable service charges, you should do so promptly after receipt of the demand.   

4) Obtain written consent for alterations 

Before undertaking fit-outs, signage changes, structural works or changes of use you should ensure that landlord consent is obtained (if it is required under the terms of your lease).  

You should obtain all approvals or licences in writing and ensure that you retain these. Landlords should provide clear service charge budgets and maintain accurate records.  

5) Comply with user and occupation restrictions  

Ensure compliance with your obligations under:  

• Permitted use clauses; 
• Planning restrictions;  
• Licensing requirements; and 
• Occupancy conditions.  

Unauthorised use of the property can expose you to enforcement action or forfeiture risk.  

6) Keep accurate records of communications and payments  

Maintain accurate records of rent payments, service charge payments, repair notifications, landlord approvals and lease correspondence  

7) Assess break clause requirements early 

Break clauses are frequently lost because technical conditions are not satisfied.  

Before exercising a break clause ensure that you review the notice requirements carefully, confirm any vacant possession obligations, settle required payments and obtain legal advice early. 

8) Prepare early for lease expiry 

Several months before lease termination you should look to assess your dilapidations exposure and reinstatement obligations. Once you know the repair requirements you can consider a settlement strategy in advance.  

Shared best practice for both Landlords and Tenants 

Always:  

• Document agreements in writing  
• Communicate promptly 
• Maintain compliance records 
• Seek legal advice before disputes escalate 

Avoid:  

• Informal verbal arrangements, WhatsApp messages etc.  
• Delayed responses to breaches 
• Unclear concessions  
• A failure to preserve evidence 

Conclusion 

Commercial leases create long-term legal and financial obligations for both landlords and tenants. Preventing disputes requires clear drafting, careful due diligence and proactive communication.  

Parties that address issues early and maintain accurate documentation are generally in a far stronger position to avoid costly litigation.
