Commercial Lease Agreement Template — Key Terms Explained

Commercial leases govern the rental of business premises — offices, retail units, warehouses, and industrial spaces. Unlike residential tenancies, commercial leases are largely governed by contract law with far fewer statutory protections for the tenant. This means the terms you negotiate matter enormously.

A commercial lease agreement template must address the type of lease (gross, net, triple net, or percentage), the permitted use of the premises, rent reviews, break clauses, repair and insurance obligations, and assignment and subletting rights.

In a gross (full-service) lease, the landlord pays for property taxes, insurance, and maintenance — the tenant pays a single rent amount. In a net lease, the tenant pays some of these costs. In a triple net (NNN) lease, the tenant pays all three: property taxes, insurance, and maintenance, plus base rent.

Understanding which structure you're agreeing to is critical because it can change your total occupancy cost by 15-30%. Always clarify the lease type before signing.

Pay close attention to the rent review clause (how and when rent increases), the break clause (whether either party can terminate early), the repair clause (who is responsible for structural vs internal repairs), and the alienation clause (whether you can assign or sublet the lease).

A commercial lease is typically 5-10 years long, so getting these terms right at the outset prevents costly disputes later. Always have a commercial property solicitor review the final agreement.
