Why Commercial Leases Demand Careful Attention
A commercial lease is typically one of the most significant financial commitments a small business will make. Unlike a residential tenancy, commercial leases are largely unregulated — the parties are free to agree almost any terms, and the law will generally hold you to what you sign.
This means the terms of a commercial lease can vary enormously, and a poorly negotiated lease can saddle your business with obligations that are difficult or impossible to exit.
Key Terms to Understand
Lease Length and Break Clauses
Commercial leases can run for anything from one year to 25 years or more. Longer leases give you security of tenure but reduce your flexibility.
Break clauses allow either party to terminate the lease early, typically on a specified date with a certain amount of notice. If you are taking a long lease, negotiate for a break clause — ideally one that is unconditional (not subject to conditions that are easy to breach).
Watch out for: Break clauses that are conditional on full compliance with all lease obligations. A minor breach — even a small amount of outstanding rent — can invalidate your right to break.
Rent and Rent Reviews
Understand not just the initial rent but how it will change over time. Common rent review mechanisms include:
- Open market review: Rent is reset to the current market rate at review dates
- Upward-only reviews: Rent can only go up, never down — even if the market falls
- RPI/CPI-linked: Rent increases in line with inflation
Watch out for: Upward-only rent review clauses, which are common in commercial leases and can leave you paying above-market rent for years.
Service Charges
In multi-occupancy buildings, tenants typically pay a service charge covering the costs of maintaining common areas, building insurance, and other shared services. Service charges can be substantial and are often variable.
Watch out for: Uncapped service charges. Try to negotiate a cap on annual increases, or at least ensure you have the right to inspect accounts and challenge unreasonable charges.
Repairing Obligations
Commercial leases typically impose significant repairing obligations on tenants. A full repairing and insuring (FRI) lease makes the tenant responsible for maintaining the property in good repair — including structural repairs.
Watch out for: Taking on a lease of a property that is already in poor condition. If you are responsible for repairs, you could be required to put the property into a better state than it was when you took it.
Schedule of condition: Before taking a lease, commission a schedule of condition documenting the state of the property. This limits your repairing obligations to maintaining the property in no worse condition than at the start of the lease.
Alienation (Assignment and Subletting)
What happens if you want to move before the lease ends? Your ability to assign the lease to another party or sublet part of the premises depends on the alienation provisions in your lease.
Many leases require landlord consent to assign or sublet, which cannot be unreasonably withheld — but the process can be slow and uncertain.
Watch out for: Absolute prohibitions on assignment or subletting, which can leave you trapped in a property you no longer need.
Personal Guarantees
Landlords often require a personal guarantee from the directors of a limited company tenant. This means that if the company defaults on its lease obligations, the directors are personally liable.
Watch out for: The extent of the guarantee. Try to limit it in time (e.g., to the first three years of the lease) and in amount.
The Negotiation Process
Commercial lease terms are negotiable — more so than many tenants realise. In a tenant's market, landlords may offer:
- Rent-free periods (often 3–6 months for fit-out)
- Reduced initial rent
- Tenant-friendly break clauses
- Caps on service charges
- Contributions to fit-out costs
Even in a competitive market, it is worth asking. The worst a landlord can say is no.
Before You Sign
Get a survey. A commercial property survey will identify structural issues and give you a clear picture of the property's condition before you take on repairing obligations.
Get legal advice. Commercial leases are complex legal documents. The cost of having a solicitor review and negotiate your lease is small compared to the potential cost of a poorly negotiated one.
Understand your exit options. Before you sign, understand exactly how you can get out of the lease if your circumstances change.
