How do leases work on commercial property?

October 6, 2026Guide

A commercial property lease in the UK is a legal agreement that lets a business occupy premises owned by a landlord for an agreed period and rent, making it suitable for organisations seeking offices, shops or other business space.

Commercial property leases set out the rights and duties of both parties. The terms can cover rent increases, deposits, repairs, insurance, maintenance and operating costs. The lease structure determines which costs the tenant pays and which remain the landlord’s responsibility.

This guide explains the main types of commercial lease, key terms and common responsibilities in plain English. It also covers practical points to consider during negotiations, so landlords and tenants can compare options, plan costs and agree clear terms before signing.

Types of Commercial Leases

1. Gross Lease

In a gross lease, the tenant pays a fixed amount of rent, and the landlord covers most expenses related to the property, such as taxes, insurance, and maintenance. This type of lease simplifies budgeting for the tenant, as they know exactly what their costs will be each month.

2. Net Lease

Net leases involve the tenant paying a portion of the property’s operating expenses in addition to the base rent. There are three main variations:

3. Percentage Lease

This type of lease is common in retail properties. The tenant pays a base rent plus a percentage of their gross sales generated on the premises. This structure aligns the interests of the landlord and tenant, as both benefit from increased sales.

Key Terms in Commercial Leases

Lease Term

The lease term refers to the duration of the lease agreement. Commercial leases can vary significantly in length, ranging from a few months to several years. Longer lease terms often provide stability but may also include rent escalation clauses.

Rent Escalation

Rent escalation clauses allow landlords to increase rent over time, usually annually. These increases can be a fixed percentage or tied to an index such as the Consumer Price Index (CPI). Tenants should understand how these clauses will affect their financial obligations over the lease term.

Security Deposit

A security deposit is typically required upfront to protect the landlord against potential damages or unpaid rent. The amount varies but is often equivalent to one to three months’ rent. It’s essential to understand the conditions under which the deposit will be returned.
