Signing a commercial lease commits your business to long-term legal and financial obligations that can shape your operations for years. If you do not review the terms carefully, you may face unexpected costs, restrictive conditions or limited flexibility to exit or adapt as your business grows. This article explores the importance of reviewing a commercial lease before signing and the key issues your business should consider as a tenant.

Why Your Business Should Carefully Review Your Lease

A lease is a crucial document that creates a legally binding contract – with the potential for long-term financial and operational implications. Under it, you may be required to accept obligations for repairs, rent reviews and insurance that could directly impact cash flow and daily operations. Without key safeguards in place, your business could also remain locked into premises that no longer suit its needs.

Because the landlord typically drafts the lease for the relevant property, it is likely to be drafted heavily in favour of the landlord and their interests. As such, conducting a thorough review from the outset will allow your business to protect itself against unwelcome surprises and seek to negotiate unfavourable terms.

Checklist of Key Considerations 

Here are some of the key issues your business should review in your proposed lease before proceeding: 

Use, Premises and Physical Obligations

  • Permitted Use: Your business should confirm that the lease expressly permits your current and intended activities and should also check whether planning permission or other licences may be required for your business purposes.
  • Alterations and Fit-Out Rights: Your business should check the clauses on alterations and fit-out. Many landlords require written consent for internal changes. The lease should allow your business to install any necessary signage, fit specialist equipment and adapt layouts as needed.
  • Repairing Obligations: Your business should understand the full extent of repairing obligations. Many leases require tenants to maintain the premises in good repair and fix any pre-existing disrepair. 

Financial Terms and Lease Flexibility

  • Rent and Financial Terms: You should carefully check not only the base rent but also every additional charge. It should be clear how and when the landlord can increase rent over time. Your business should also review what the service charge covers, how the landlord calculates and recovers costs and whether any management or estate fees apply. When budgeting, you will need a clear understanding of the total financial commitment over the lease’s life (e.g., for rent reviews, service charges, repairs, business rates, and insurance premiums).
  • Lease Term, Break Clauses and Renewal Rights: Your business should ensure the lease length supports your business plans and carefully check the term and renewal rights. Where flexibility matters, your business should negotiate a break clause. You should also check whether the lease is protected by the Landlord and Tenant Act 1954 or has been contracted out, as only protected leases carry a statutory right to renewal.
  • Assignment and Subletting: If your business might need to transfer the lease or share space with another company, it should ensure the lease permits assignment or subletting on workable terms. 
  • Compliance with Statutory Requirements: Your business should confirm that the lease and property comply with applicable legal rules (including fire safety, health and safety, accessibility and minimum energy-efficiency standards).

These are a few examples of key clauses to review with care. However, your lease may include many other provisions, depending on the property and sector.

Even if your business has negotiated commercial contracts before, you should not underestimate the complexity of a commercial lease. These documents will often contain technical wording that can be difficult to interpret without legal expertise.

A commercial property solicitor can guide you on the lease and your rights and obligations, identify and explain complex clauses and seek to negotiate key terms on your behalf. If your business operates in a specialised sector (for example, hospitality, healthcare or manufacturing) or has niche operational requirements, a property solicitor can help address any additional sector-specific issues. They can also advise on which lease structure best matches operational needs and financial strategy. The cost of investing in legal review is likely to be far less than the potential expense and stress of disputes or being locked into unsuitable premises.
