Overview

Sustainability is no longer just a buzzword in commercial property. Across the UK, environmental performance is becoming a key consideration for landlords, investors and occupiers alike. One of the clearest signs of this shift is the growing use of green clauses in commercial leases.

For tenants, these clauses can introduce new responsibilities, costs and opportunities. Understanding what they mean and how they affect your lease, is essential before you sign or renew a tenancy.

This article explains what green clauses are, how they work in a UK context and what tenants need to know about their sustainability obligations.

 

What is a green lease?

A green lease (sometimes referred to as a sustainable property lease) is a commercial lease that includes provisions aimed at improving the environmental performance of a building. These clauses are designed to encourage cooperation between landlord and tenant on issues such as energy efficiency, waste reduction and sustainable building use.

Green leases can range from light-touch obligations, such as sharing energy data, to more demanding requirements that affect how a tenant operates and maintains the property.

 

What are green clauses in practice?

Green clauses vary widely, but they commonly focus on how a property is used, maintained and improved over the life of the lease. Rather than being a single standard clause, they are usually a collection of provisions embedded throughout the lease.

From a tenant’s perspective, these clauses often influence day-to-day operations as well as longer-term decisions about fit-out, alterations and maintenance. The key is understanding where responsibility sits and what is reasonable for your business.

Common tenant sustainability obligations

For tenants, green clauses may introduce obligations such as using energy efficiently, sharing consumption data with the landlord or complying with building-wide sustainability initiatives. In some cases, tenants may be required to use energy-efficient lighting, limit waste generation or avoid alterations that negatively impact the building’s environmental performance.

Other clauses may restrict how plant and equipment are installed or replaced, particularly if changes could reduce energy efficiency or affect an EPC rating. Some leases also include cooperation clauses, requiring tenants to engage with the landlord on sustainability improvements or future works.

While many of these obligations sound sensible, they can still carry cost and operational implications if not fully understood.

Why green clauses matter for tenants

Green clauses are often presented as environmentally positive, and they can be, but tenants should not assume they are risk-free. Depending on how they are drafted, they may increase running costs, restrict flexibility or create uncertainty at lease end.

For example, a tenant may be required to reinstate sustainable features installed during the tenancy or face limitations on alterations that would otherwise support business growth. There can also be overlap between green clauses and traditional repair or reinstatement obligations, which may lead to disputes if responsibilities are unclear.

Understanding these clauses early allows tenants to budget accurately, negotiate fair terms and avoid surprises later in the lease.

How green clauses interact with dilapidations

One area where tenants should take particular care is how green clauses link to dilapidations at lease expiry. Sustainability-related improvements, such as energy-efficient installations or alternative materials, can complicate reinstatement obligations if the lease is not clear.

A tenant may assume that environmentally beneficial alterations can remain, only to discover that the lease requires full reinstatement. Without proper advice, this can result in unexpected costs and disputes at the end of the tenancy.

What tenants should do before signing a green lease

Before agreeing to a sustainable property lease, tenants should ensure they fully understand what is being asked of them. This includes reviewing how green clauses interact with repair, alterations and reinstatement provisions and whether the obligations are proportionate to the size and nature of the business.

Professional advice can help clarify risks, identify unreasonable clauses and, where appropriate, negotiate more balanced terms. A building surveyor can also advise on the practical implications of sustainability requirements and how they may affect future costs.
