Part ofCommercial Property

Updated June 2026 · England & Wales
Signing a commercial lease is one of the biggest financial commitments a business can make, and the document you put your name to will shape your costs, flexibility and obligations for years. Unlike residential tenancies, commercial leases in England and Wales give the parties considerable freedom to negotiate, which means the terms you accept up front are largely the terms you are stuck with. That freedom cuts both ways. A well-negotiated lease can protect your cash flow and your ability to exit if circumstances change; a poorly understood one can leave you paying for repairs you never caused, tied in during a downturn, or facing dilapidations claims at the end of the term. This guide, written by Brad Askew, walks through the provisions that matter most and the questions tenants often wish they had asked earlier.

What this document is

A commercial lease is a contract between a landlord (the lessor) and a business tenant (the lessee) that grants the tenant exclusive possession of premises for a defined period in return for rent. It sits within a mix of contract law, property law and statute, most notably the Landlord and Tenant Act 1954, which can give qualifying business tenants a right to renew at the end of the term unless that protection has been contracted out through the proper statutory procedure.

Commercial leases cover offices, shops, warehouses, industrial units and mixed-use spaces, and they vary enormously in length, structure and risk allocation. Short leases of one to three years are common for new businesses, while longer terms of ten or fifteen years often come with rent reviews and more onerous repair obligations.

Whatever the length, the lease will usually set out the permitted use, the rent and any service charge, who pays for insurance, repair and maintenance standards, rules on alterations, assignment and subletting, and the circumstances in which either party can end the arrangement early.

How to use this document

  1. Check the parties, premises and term. Make sure the landlord named is the actual freeholder or head tenant, and that the demised premises are described clearly, including boundaries, shared areas and any rights of way. Confirm the start date, length of term and whether a break clause applies. Mistakes here cause disputes later.
  2. Understand the rent, reviews and other payments. Look beyond the headline rent. Check how often it is payable, whether VAT is added, and how any rent review works, whether open market, indexed to RPI or CPI, or stepped. Factor in service charges, insurance rent, business rates and utilities to see the true annual cost of occupation.
  3. Pin down repair and insurance obligations. Full repairing and insuring (FRI) leases put almost all the burden on the tenant, including putting the property into repair even if it was not in that state at the start. Consider negotiating a schedule of condition to cap your liability, and check who insures the building and who pays the premium.
  4. Review use, alterations, assignment and subletting. The permitted use clause controls what your business can actually do on site and whether planning use class changes are allowed. Alterations usually need landlord consent. If you may want to move, sell the business or sublet part of the space, the flexibility (or rigidity) of the assignment clauses will be crucial.
  5. Look at how the lease ends. Check any break clause conditions very carefully, as minor breaches can invalidate a break. Consider whether the lease is inside or outside the security of tenure provisions of the 1954 Act, and understand your likely dilapidations exposure when the term finishes.

Common questions

Q What is the difference between an FRI lease and an internal repairing lease?
A full repairing and insuring lease makes the tenant responsible for all repairs to the premises, inside and out, and for reimbursing the landlord's insurance premium. An internal repairing lease limits the tenant's obligation to the interior, with the landlord handling the structure, roof and exterior. FRI terms are common for whole buildings, while internal repairing terms are more typical for units within a larger property.
Q What does 'contracted out' of the Landlord and Tenant Act 1954 mean?
Business tenants normally have a statutory right to renew their lease at the end of the term under Part II of the 1954 Act. A landlord can require the tenant to give up that right before the lease is granted, but only by following a set procedure involving a warning notice and a tenant declaration. If this has been done correctly, the tenant must leave at the end of the term with no automatic right of renewal.
Q How does a rent review usually work?
Most rent reviews are either upwards-only open market reviews, where the rent is reset to current market levels but cannot fall, or index-linked reviews tied to RPI or CPI. Stepped rents with pre-agreed increases are also common on shorter leases. The review mechanism, frequency and any caps or collars significantly affect your long-term costs, so it is worth modelling different outcomes before signing.
Q Can I get out of a commercial lease early?
Only if the lease allows it or the landlord agrees. A break clause gives one or both parties the right to end the lease on set dates, but break conditions are often strict and courts tend to enforce them literally. Otherwise you may be able to assign the lease to another business or sublet with landlord consent, or negotiate a surrender, though the landlord is not obliged to accept one.
Q What are dilapidations and why do they matter?
Dilapidations are the landlord's claims for breaches of the tenant's repair, decoration and reinstatement obligations, usually raised at or near the end of the lease. On an FRI lease they can run into significant sums. A schedule of condition agreed at the start, photographic evidence of the premises on day one, and sensible budgeting for end-of-term works can all help reduce exposure.
Q Do I need a solicitor to sign a commercial lease?
There is no legal requirement, but commercial leases are long, technical documents with long-term financial consequences, and most tenants instruct a solicitor to review and negotiate the draft. Heads of terms agreed with the landlord or agent are usually 'subject to contract' and can be pushed back on. Getting proper input before you sign is almost always cheaper than dealing with problems later.
Q Is a commercial lease registered at the Land Registry?
Leases granted for more than seven years must be registered at HM Land Registry, and shorter leases can sometimes be noted against the landlord's title. Registration gives the tenant's interest protection against third parties. Your solicitor will usually handle registration as part of the post-completion work, and there is a fee payable to the Land Registry.
