Key Takeaways
- Commercial lease terms are almost always negotiable – heads of terms set out the agreed commercial deal before the formal lease is drafted.
- Tenants should push for a rent-free period at the start of the lease to cover fitting out costs and the early months before the business is fully operational.
- A break clause gives the tenant the right to exit before the end of the lease term on fixed conditions – making it one of the most valuable provisions to negotiate.
- Full repairing and insuring leases make tenants responsible for all repair and insurance costs. Understanding the extent of these obligations before signing is essential.
Many business tenants sign commercial leases without realising how much flexibility exists in the terms. Unlike residential tenancies, commercial leases are individually negotiated. There is no standard form that must be used, and almost every provision is open to discussion. The tenant who understands this before negotiations start is in a much stronger position than one who accepts the landlord’s first draft without question.
This article covers the key areas where negotiation makes the most difference. Our commercial property solicitors at Osbourne Pinner offer a free 30-minute consultation and can advise on lease terms and negotiating strategy for your specific situation.
Start With Heads of Terms
Before a lease is formally drafted, the parties typically agree heads of terms: a summary of the key commercial points including the rent, lease length, break clause dates, rent review mechanism and any tenant incentives. Heads of terms are usually not legally binding, but they set the framework for everything that follows.
It is far easier to negotiate key terms at the heads of terms stage than after a solicitor has produced a first draft lease based on the landlord’s position. Getting the commercial deal right at the outset saves significant time and professional fees later.
Rent and Rent-Free Periods
The headline rent is negotiable, but landlords are often more flexible on tenant incentives than on the face rent, particularly in markets where there are several comparable properties available. The most common incentive is a rent-free period at the start of the lease, during which no rent is payable. This is designed to allow the tenant to fit out the premises and establish the business before full rent obligations kick in.
The length of the rent-free period depends on the state of the premises and the state of the market. For a shell-and-core property needing significant fit-out, a 6-12 month rent-free period is reasonable to ask for. For a ready-to-occupy property in a strong market, a landlord may offer less. Whatever is agreed, it should be clearly documented in the heads of terms.
Lease Length and Break Clauses
Commercial leases commonly run for 5, 10 or 25 years. A longer lease offers security but limits flexibility. A break clause allows the tenant (and sometimes the landlord) to end the lease early on a specific date, usually on 6 months’ notice. Break clauses are one of the most valuable provisions a tenant can negotiate.
Break clauses are often conditional. They only work if the tenant has complied with all lease obligations up to the break date. Courts interpret these conditions strictly, and a tenant who exercises a break clause but has outstanding rent arrears, even a small amount, may find the break is ineffective. The conditions attached to a break clause should be scrutinised carefully before signing. For guidance on what happens after a break clause is exercised, see our break clause and surrender page.
Rent Review: The March 2026 Change
From 17 March 2026, upward-only rent review clauses are void in new commercial leases. For leases granted after that date, the rent review mechanism must allow for rent to move down as well as up in line with market conditions. This is a significant change for tenants negotiating new leases, removing one of the most commercially one-sided features of the traditional commercial lease.
Tenants should still pay careful attention to how the review clause is drafted: the assumptions made about the hypothetical letting, the disregards and the mechanism for resolving disputes if the parties cannot agree on the reviewed rent. Getting these right matters even where the upward-only ratchet is gone.
Repair and Service Charge Obligations
Most commercial leases are let on full repairing and insuring (FRI) terms, meaning the tenant takes on responsibility for maintaining the property in good repair and keeping it insured. In practice, this can mean a tenant is required to hand back the property at the end of the lease in better condition than they received it. That is a significant financial exposure.
Tenants should push for a schedule of condition, which is a photographic and written record of the property’s state at the start of the lease, and for a provision that their repair obligation extends only to keeping the property in the condition shown in that schedule. Without a schedule of condition, the tenant’s repair liability on a FRI lease can be open-ended.
For leases of part of a building, a service charge will usually apply. Tenants should ask for a cap on service charge increases in the early years of the lease and for detailed information about what the service charge covers before signing.
Alienation Rights: Assignment and Subletting
Alienation provisions govern what the tenant can do if their business needs change and they want to transfer the lease to someone else (assignment) or let part of the premises (subletting). Leases often restrict these rights, requiring the landlord’s consent before any transfer can take place.
Tenants should ensure the lease specifies that consent cannot be unreasonably withheld or delayed, and that the grounds on which it can be refused are clearly set out. Broad, undefined restrictions on alienation can leave a tenant trapped in a property if they need to exit before the lease ends or the break date arrives.

Permitted Use
The permitted use clause defines what the tenant can use the premises for. A narrow use clause (such as ‘retail sale of clothing only’) limits the tenant’s flexibility to adapt the business and can make the lease harder to assign. Tenants should push for a broader use clause that reflects the range of activities the business might reasonably carry out, while remaining acceptable to the landlord.
Speak to a Commercial Property Solicitor Before Signing a Lease
A commercial lease is typically one of the largest financial commitments a business makes. Signing without taking legal advice – or taking it too late in the process, after the heads of terms have already been agreed – can leave tenants locked into terms they did not fully understand. The time to negotiate is before the lease is drafted, not after.
At Osbourne Pinner, our commercial property solicitors advise business tenants and landlords on commercial lease negotiations, heads of terms and the full range of lease terms. We can review a draft lease, advise on what to push back on and negotiate on your behalf.
