Key Clauses in a UK Commercial Lease

Rent Review Clauses

Rent review clauses determine how rent adjusts during the lease term. The three most common mechanisms in UK commercial property are:

• Open market rent review: Rent is adjusted to reflect the current market value at each review date, typically every 3-5 years. Upward-only clauses prevent rent from decreasing below the current level.

• CPI or RPI-linked review: Rent increases in line with the Consumer Price Index or Retail Price Index, providing predictable annual adjustments.

• Fixed uplift: Rent increases by a predetermined percentage or amount at each review date, offering certainty for both parties.

Break Clauses

A break clause gives the tenant, landlord, or both the right to terminate the lease before the contractual expiry date. In the UK, break clauses typically require 6-12 months' written notice, strict compliance with conditions (vacant possession, rent paid up to date, no outstanding breaches), and precise timing of the break notice.

Repairing Covenants

The repairing covenant defines who is responsible for maintaining and repairing the property. In the UK, the standard structures are:

• Full Repairing and Insuring (FRI): The tenant is responsible for all repairs, internal and external, plus building insurance contributions. Standard for single-tenant properties.

• Internal Repairing and Insuring (IRI): The tenant handles internal repairs only. The landlord maintains the structure, exterior, and common areas, recovering costs through the service charge. Common in multi-tenant buildings.

Alienation Provisions

Alienation clauses control the tenant's ability to transfer, sublet, or share occupation of the premises. Most UK commercial leases permit assignment with landlord consent (not to be unreasonably withheld) and may restrict subletting to the whole premises only.

How to Customise a Commercial Lease Template for UK Law

In 2026, UK commercial lease negotiations continue to reflect post-pandemic shifts toward greater tenant flexibility. Shorter lease terms, more frequent break clauses, and increased negotiation around repair caps and dilapidation limitations are now standard in many market segments. Landlords are also more open to turnover-based rent components in retail leases and flexible space arrangements.

Adapting a template for your specific situation requires attention to several UK-specific considerations.

• Security of tenure: Decide whether the lease will be protected under the Landlord and Tenant Act 1954 (giving the tenant renewal rights) or contracted out. Contracting out requires a formal notice and declaration process before the lease is completed.

• Planning use class: Confirm the permitted use aligns with the property's planning use class. The UK's Use Classes Order (Class E for commercial, B2 for industrial, B8 for storage) determines what activities are legally permitted.

• Stamp Duty Land Tax (SDLT): Tenants in England and Northern Ireland must pay SDLT on leases where the net present value of rent exceeds the current threshold. Scotland applies Land and Buildings Transaction Tax (LBTT), and Wales applies Land Transaction Tax (LTT).

• Guarantor and authorised guarantee agreements: Where the tenant is a new company or has limited financial history, landlords may require a personal or corporate guarantor. On assignment, the outgoing tenant may need to enter an Authorised Guarantee Agreement (AGA).

• Dilapidations: Include clear schedules of condition at lease start to limit dilapidation exposure at lease end. The terminal dilapidation claim is capped by Section 18(1) of the Landlord and Tenant Act 1927.

How to Implement Your Commercial Lease

To maximize the benefits of your commercial lease template, consider implementing it with the right property management tools:

• Lease creation and management: Use commercial property management software to streamline the lease creation process, automatically populating lease agreements with property and tenant details.
• E-signatures: Utilize e-signature functionality to expedite the execution of the lease agreement, making it more convenient for both parties.
• Secure storage and data extraction: Store executed leases securely in the cloud for easy access and reference. Some systems, such as Credia Plus, an AI tool within Re-Leased, also use AI to extract key information from lease documents into a centralised dashboard — giving you a clear, structured view of your lease terms without having to comb through PDF pages.
  
• Monitoring: Use lease management templates or software to track key dates, such as rent reviews and renewals, and to monitor the tenant’s compliance with lease terms. Some platforms, like Credia Plus within Re-Leased, offer AI-powered tools that let you chat directly with your lease documents — allowing you to ask questions and get answers in seconds, without having to look through hundreds of pages.
  

Why Use a Commercial Lease Template?

• Reduce drafting costs: Solicitor fees for drafting a commercial lease from scratch typically start at several hundred pounds. A well-structured template provides a solid foundation that reduces billable hours for legal review.

• Ensure comprehensive coverage: Templates include standard provisions that might be overlooked in ad hoc drafting, including break clause mechanics, rent review procedures, and dilapidation schedules.

• Maintain portfolio consistency: Landlords managing multiple properties benefit from standardised lease structures that simplify administration, reporting, and compliance tracking.

• Accelerate negotiations: Starting from a complete template shortens the heads of terms to completion timeline, keeping deals on track.
