The Commercial Lease Clauses That Catch Businesses Off Guard (And How to Avoid Them)

There is a particular kind of confidence that comes from agreeing a rent. The number is settled, the handshake is done, and the premises feel almost yours. What comes next, the actual lease document, is where that confidence can get expensive.

Commercial leases run for years. Some of what sits inside them will shape a business's finances, flexibility and options long after the ink dries. Yet the clauses that matter most are precisely the ones that tend to get the least attention at the point of signing.

Security of tenure: the right you might accidentally waive

The Landlord and Tenant Act 1954 gives business tenants in England and Wales a statutory right to renew their lease at the end of its term. It is a meaningful protection, and landlords can only refuse renewal on specific legal grounds. But those rights can be contracted out of, and often are. When a lease excludes the 1954 Act, the tenant has no automatic right to stay when the term ends. That might be acceptable for short occupations, but for a business building its identity around a location, it is a very different matter. The question of whether a lease includes or excludes 1954 Act protection should be the first thing any tenant clarifies, not an afterthought.

Repairing obligations: who fixes what, and in what condition

A full repairing and insuring lease puts the cost of keeping the property in good order squarely on the tenant, regardless of what state it was in when they arrived. For an older building, that can mean inheriting someone else's damp problem and being obliged to resolve it. A schedule of condition, agreed and attached at the outset, limits liability to the property's actual state at the start of the tenancy. Without one, the exposure is open-ended. It is a detail that gets overlooked constantly and costs tenants considerably.

Break clauses: the escape route that only works if you use it correctly

Break clauses offer the theoretical freedom to exit a lease early. In practice, they come with conditions: notice periods, compliance requirements, rent arrears provisions. Miss the window by a day, or be technically in breach of a condition at the point of exercise, and the break simply does not operate. The lease continues. Break clauses need to be understood properly before they are relied upon.

A solicitor-reviewed commercial lease from LeaseAssured costs £895 plus VAT, covers more than 50 professionally drafted clauses, and is available entirely online for landlords and businesses across England and Wales.

Permitted use: the flexibility you might need later

A lease that specifies a very narrow permitted use can become a trap when a business wants to evolve. Adding a product line, changing a service model or subletting to a different type of occupier can all require landlord consent if the permitted use clause is tightly drawn. Negotiating a broader permitted use at the outset, where a landlord will agree to it, costs nothing extra. Trying to change it later does.
