The best lease type for commercial property depends on your business needs, budget flexibility, and risk tolerance. No single lease structure suits every tenant or landlord. You need to understand how each type affects your costs and responsibilities.

The Four Main Commercial Lease Types
1. Full Repairing and Insuring Lease (FRI)
An FRI lease makes you responsible for all building costs. You pay:
- Rent
- Property insurance
- All repairs (internal and external)
- Maintenance of structure and services
Who it suits: Tenants wanting full control over the property without landlord interference. Common in single-occupancy buildings.
Drawbacks: You carry all financial risk if major repairs arise. A new roof or heating system comes from your budget.
2. Internal Repairing and Insuring Lease (IRI)
You handle interior maintenance while the landlord manages the building’s exterior and structure. Your costs include:
- Rent
- Interior repairs and decoration
- Internal fixtures and fittings
- Service charge for shared areas (in multi-let buildings)
Who it suits: Small to medium businesses in shared buildings. You control your workspace without structural headaches.
Drawbacks: Service charges can increase unpredictably if major works occur.
3. Triple Net Lease (NNN)
Similar to FRI leases, triple net agreements pass nearly all costs to you:
- Base rent
- Property taxes
- Insurance premiums
- Maintenance and repairs
Who it suits: Established businesses with stable cash flow. More common in the US but appears in UK commercial property.
Drawbacks: Unpredictable expenses make budgeting difficult for smaller operations.
4. Gross Lease (All-Inclusive)
The landlord covers most property costs. You pay a single rent figure that includes:
- Building insurance
- Property maintenance
- Service charges
- Sometimes utilities
Who it suits: Startups and small businesses wanting predictable monthly costs. The best lease type for commercial property if you need budget certainty.
Drawbacks: Higher base rent because landlords build costs into the price. Less control over building standards.
Which Lease Type Works Best?
Your ideal lease depends on several factors:
Consider Your Business Size
- Small businesses and startups: Gross leases offer simplicity and predictable costs
- Growing companies: IRI leases balance control and responsibility
- Large corporations: FRI or NNN leases provide autonomy over the entire property
Assess Your Financial Stability
Can you absorb unexpected repair costs? FRI leases expose you to significant financial risk if the boiler fails or the roof leaks. Gross leases protect against surprises but cost more upfront.
Evaluate Property Condition
Older buildings carry higher repair risks. An FRI lease on a Victorian office could become expensive fast. Newer properties suit FRI arrangements better.
Think About Lease Length
Longer leases (10-25 years) often come with FRI terms. Shorter agreements (3-5 years) typically use IRI or gross structures. Match the lease type to your commitment level.
The Most Popular Choice in the UK
IRI leases dominate UK commercial property markets. They offer a practical middle ground:
- Tenants control their workspace
- Landlords maintain building integrity
- Costs are reasonably predictable through service charges
- Risk splits fairly between parties
This makes IRI the best lease type for commercial property for most UK businesses.
Key Negotiation Points
Whatever lease type you choose, negotiate these terms:
- Rent reviews: How often and by what method (fixed increases, market rate, or index-linked)
- Break clauses: Options to exit early if your business changes
- Service charge caps: Limits on annual increases
- Repair schedules: Clear definitions of who fixes what
- Alienation rights: Your ability to sublet or assign the lease
Get Professional Advice
Commercial leases create long-term legal obligations. A poor choice costs you thousands in unexpected expenses or restricts your business growth.
Hire a commercial property solicitor before signing. They’ll review terms, spot unfair clauses, and negotiate better conditions. The fee is small compared to potential losses from a bad lease.
The best lease type for commercial property for your business balances cost predictability against control. Assess your finances, consider your growth plans, and match the lease structure to your operational needs. An IRI lease works for most tenants, but your specific situation might call for different terms.
