Before signing a commercial lease, you need to understand the key terms that will govern your business premises for the duration of the tenancy. A commercial lease is a legally binding contract — often running for five, ten or more years — and the obligations it imposes on you as a tenant can have a significant impact on your business finances and operations if they are not properly understood before you commit.
This guide explains the main provisions of a commercial lease agreement, what to look out for before signing, and how the law in England and Wales protects (or does not protect) commercial tenants.
What is a Commercial Lease Agreement?
Unlike residential tenancies, commercial leases in England and Wales are largely governed by the agreement between the parties rather than by statutory protection. The terms of a commercial lease are therefore negotiable, and it is important to understand what you are agreeing to before the lease is signed. Once signed, the terms bind both landlord and tenant for the duration of the lease, subject only to any amendment agreed in writing.
Key Terms to Check in a Commercial Lease
A commercial lease will typically contain a large number of provisions. The following are the most important terms to review and understand before entering into any commercial tenancy:
Rent and Rent Deposits
Check the initial rent, the frequency of payment (monthly or quarterly in advance is most common) and whether a rent deposit is required. Rent deposits are typically held by the landlord as security and should be protected under a formal rent deposit deed that sets out the conditions for its release at the end of the lease.
Lease Term and Break Clauses
Understand the length of the lease and whether there are any break clauses — provisions allowing early termination by one or both parties. A tenant-only break clause provides flexibility to exit if circumstances change. Check the notice period required to exercise any break and the conditions that must be met (typically vacant possession and payment of all sums due).
Rent Review
Most commercial leases include a mechanism for reviewing the rent at intervals during the term — typically every three or five years. Upward-only rent review clauses, which prevent the rent from falling even if market rents have declined, are standard but disadvantageous for tenants. Check the review mechanism (open market, RPI, fixed uplift) and the review timetable.
Repairing Obligations: FRI vs Internal Repairing Only
A full repairing and insuring (FRI) lease places responsibility for all repairs and the cost of insurance on the tenant. An internal repairing only (IRI) lease limits the tenant's obligations to the interior of the demised premises. In a multi-let building, the landlord typically recovers the cost of external and structural repairs through a service charge. You should always obtain a schedule of condition at the start of the lease to limit your repair liability on exit.
Dilapidations
Dilapidations are claims by the landlord for the cost of repairing the property to the standard required by the lease at the end of the tenancy. These claims can be substantial. A schedule of condition limits your exposure by establishing the baseline condition of the property at lease commencement.
Assignment and Subletting
Check whether the lease allows you to assign (transfer) the lease or sublet all or part of the property. Most commercial leases restrict assignment and subletting to cases where the landlord gives consent — which must not be unreasonably withheld. Some leases require the outgoing tenant to give an authorised guarantee agreement (AGA) on assignment, guaranteeing the obligations of the new tenant.
Service Charges
In multi-let buildings, tenants pay a service charge contribution towards the cost of maintaining common areas, the structure and shared services. Check the service charge cap (if any), how costs are apportioned and what items the landlord can recover. Uncapped service charges can be unpredictable and expensive.
What is the Landlord and Tenant Act 1954 and Does it Apply to You?
The Landlord and Tenant Act 1954 gives business tenants in England and Wales a statutory right to remain in their premises and apply to the court for a new tenancy at the end of the lease term. This is known as security of tenure. Where the 1954 Act applies, a landlord can only refuse to grant a new tenancy on limited statutory grounds — for example, if they intend to redevelop the property or occupy it themselves.
However, many commercial leases are contracted out of the 1954 Act by agreement before the lease is entered into. This process requires the landlord to serve a formal warning notice on the tenant, who must then sign a statutory declaration acknowledging that they will have no right to a new tenancy at expiry. If your lease has been contracted out, you have no statutory right to remain in your premises at the end of the term and no right to apply for a new tenancy.
Always check whether the 1954 Act applies to your lease before signing, and take legal advice on the implications for your business if the lease is contracted out.
Understanding Dilapidations: Your Obligations at Lease End
Dilapidations are one of the most common areas of dispute between commercial landlords and tenants. At the end of a lease, the landlord is entitled to require the tenant to return the property in the condition required by the lease — typically repaired, decorated and cleared of all alterations carried out during the tenancy.
Landlords usually serve a dilapidations schedule towards the end of the lease term or after handback, setting out the works they say the tenant must carry out or pay for. The tenant has the right to challenge items on the schedule and to argue that the landlord has suffered less loss than the cost of the claimed works (the supersession argument, under s18 of the Landlord and Tenant Act 1927).
To protect your position from the outset, always insist on a detailed schedule of condition being annexed to the lease at the start of the tenancy. This records the condition of the property photographically and in writing, and limits your obligation to returning the property in no better condition than when you took it. Without a schedule of condition, you may face liability for repairing defects that pre-existed your tenancy.
Rent Review Clauses: What Tenants Need to Know
Rent reviews are a standard feature of most commercial leases. The purpose of a rent review is to adjust the rent during the lease term to reflect changes in market rents. In England and Wales, the most common type of rent review is the open market rent review, which resets the rent to the level that the property would achieve if let on the open market at the review date, on the assumptions set out in the lease.
Almost all commercial leases include an upward-only rent review clause, which means the rent can increase at review but cannot fall. If market rents have declined since the last review, the rent stays at its existing level. Tenants should model the financial impact of potential rent increases before signing a long lease. Alternative review mechanisms include RPI-linked increases, fixed percentage uplifts, and open market with a cap and collar — each of which has different risk profiles for tenant and landlord.
Checklist: What to Check Before Signing a Commercial Lease
- Confirm the demise: Check exactly what premises you are being granted — including any car parking, storage or shared areas — and ensure this matches what was agreed in heads of terms.
- Verify the term and break rights: Confirm the length of the lease, the contractual expiry date and whether any break clauses exist, in whose favour they operate and what conditions must be met to exercise them.
- Check the rent and review mechanism: Understand the initial rent, any rent-free period, the frequency of payment and the rent review provisions, including whether review is upward only and what basis is used for the review.
- Understand your repair obligations: Establish whether the lease is FRI or IRI, insist on a schedule of condition and check whether you are responsible for inheriting pre-existing disrepair.
- Assess alterations provisions: Check what alterations you are permitted to carry out during the tenancy and what reinstatement obligations you will have at the end of the lease.
- Check assignment and subletting rights: Ensure you have adequate flexibility to assign or sublet the lease if your business needs change during the term, and understand any conditions the landlord can impose.
- Consider security of tenure: Establish whether the 1954 Act applies and, if not, understand the implications for your business at the end of the lease.
- Review service charge provisions: In multi-let buildings, check what services are recoverable, how costs are apportioned and whether there is a cap on your annual service charge liability.
Frequently Asked Questions About Commercial Leases
- While there is no legal requirement to instruct a solicitor, it is strongly advisable. Commercial leases are legally binding documents that typically run for years and impose significant financial obligations. A solicitor will review the terms, advise on the Landlord and Tenant Act 1954, negotiate amendments in your favour, raise enquiries about the property and handle the registration formalities. The cost of getting legal advice before signing is far less than the potential cost of an unfavourable lease term locked in for five or ten years.
- A full repairing and insuring (FRI) lease places responsibility for all repairs and the cost of building insurance on the tenant, regardless of the condition of the property at the start of the lease. This is the most common structure for commercial leases in England and Wales. Before signing an FRI lease, you should obtain a schedule of condition — a photographic and written record of the property's state at the start of the lease — to limit your repair liability to returning the property in no better condition than it was when you took it.
- Security of tenure is the right given to business tenants under the Landlord and Tenant Act 1954 to remain in their premises and request a new lease at the end of the contractual term. A landlord can only refuse renewal on limited statutory grounds. Many commercial leases are 'contracted out' of the Act, meaning the tenant has no automatic right to a new lease at expiry. You should always check whether the 1954 Act applies to your lease before signing, as this significantly affects your security as a tenant.
- Dilapidations are the disrepair and breaches of repairing covenant that a tenant is liable for at the end of the lease. At lease expiry, landlords commonly serve a dilapidations schedule setting out the works they say the tenant must carry out or pay for. The cost of a dilapidations claim can be significant. You can limit your exposure by agreeing a schedule of condition at the outset, maintaining the property during the term and seeking professional dilapidations advice before the lease expires.
- An upward-only rent review clause means that at each rent review date, the rent can only stay the same or increase — it can never reduce, even if open market rents have fallen. This is the standard position in most commercial leases in England and Wales. Tenants should be aware that upward-only review clauses mean they are locked into a minimum rent level for the remainder of the lease, irrespective of changes in the property market. The timing and mechanism for rent review should be reviewed carefully before signing.
