Before You Sign on the Dotted Line: The Lease Clauses That Quietly Bleed Small Businesses Dry

Ask any tenant what their premises cost and they will quote the rent. Ask them two years in, after an unexpected dilapidations bill or a failed break attempt, and the answer changes. Commercial leases are drafted by landlords' solicitors, and the clauses that matter most are rarely the ones on the front page. If you are about to sign your first — or your next — lease, these are the five provisions that deserve a line-by-line reading.
1. Dilapidations: The End-of-Term Bill You Inherit on Day One
Most leases require tenants to return the property in good repair, and many older leases demand even improvements to the property's original condition. The trap is simple: a tenant who never repairs during the term faces a terminal dilapidations claim at the end — often tens of thousands of pounds, assessed by the landlord's surveyor under the protocol governing pre-action claims.
What to negotiate: Cap your repairing obligation by reference to a schedule of condition — a photographic and written record of the property's state at the start of the lease, attached to it, limiting your liability to that condition. If the landlord refuses, at minimum ensure the lease excludes liability for inherent defects and pre-existing disrepair.
2. Break Conditions: A Break Clause That Isn't Really One
A break clause lets you end the lease early — but only if you satisfy every condition attached to it, strictly. Landlords frequently require that rent is paid up to date, that no breach of covenant exists, and sometimes that the tenant has given vacant possession. Courts have held tenants to these conditions with unforgiving rigidity; a single day's late rent has been enough to defeat a break notice worth hundreds of thousands of pounds.
What to negotiate: Push for the condition to be limited to payment of principal rent only, with a right to remedy (or a refund of) any arrears. Confirm precisely how and when notice must be served, and diarise the date with your solicitor and accountant alike.
3. Rent Review Triggers: The Uplift Hiding in the Arithmetic
Most leases over five years contain rent reviews, typically at the third or fifth year. The mechanism matters enormously. An open market review is bad enough in a rising market; an upward-only review means rent can never fall even if the market does — a feature that kept many tenants paying boom-era rents through the last downturn.
Watch also for reviews linked to RPI or CPI with a collar and a floor — a minimum uplift of, say, 2% regardless of inflation — and for the landlord's ability to trigger a review by notice, with backdated interest if you delay.
What to negotiate: Seek a review capped at the higher of the open market rent and the current rent (removing the upward-only effect), or at index-linked movement with no floor. If the landlord insists on upward-only, ask for a rent cap or a shorter fixed term instead.
4. Personal Guarantees: Signing as Yourself, Not Just Your Company
Limited liability is one of the main reasons businesses incorporate — and personal guarantees quietly dismantle it. Where a landlord doubts the covenant strength of a new company, it will ask the directors to guarantee the tenant's obligations personally. That means if the business fails, the landlord pursues the individual for all rent and losses for the remainder of the term.
What to negotiate: Limit the guarantee to a fixed sum or to a defined period (for example, the first two years), and insist on a release mechanism once the company has demonstrated a trading history. Where several directors are asked to guarantee, seek several — not joint and several — liability, so each is exposed only for their own share.
5. Alienation Restrictions: The Cage Around Your Exit
'Alienation' clauses govern whether you can assign the lease, sublet, or share occupation. A lease that prohibits assignment entirely turns your premises into a liability you cannot sell: if your business outgrows the unit, relocates, or folds, the lease remains your problem until it expires.
Landlords may also require authorised guarantee agreements (AGAs), under which an outgoing tenant remains liable for an assignee's failures — a chain of lingering liability that can stretch across multiple assignments.
What to negotiate: Insist on a right to assign the whole lease to a reputable assignee with the landlord's consent, such consent not to be unreasonably withheld (a statutory backstop under the Landlord and Tenant Act 1927). Resist open-ended AGA obligations, or limit them to the first assignment only.
Read the Lease Before It Reads You
None of these clauses is fatal in itself. Together, they can double the real cost of a lease that looked affordable on the headline rent. The pattern is consistent: landlords' standard drafts assume you will not read them, and the tenants who do — with a solicitor at their side — routinely secure better terms simply by asking.
Before you sign, commission a proper review of the draft lease, obtain a schedule of condition where the premises are not new, and model your total occupancy cost across the full term, including reviews and anticipated repairs. The hour you spend on the paperwork is the cheapest insurance you will ever buy for your business.
