Nearly 95% of UK businesses lease their commercial premises rather than own them, according to recent data. That means the vast majority of business owners across the country are navigating lease agreements, landlord negotiations, and legal protections — often without a clear picture of what they’re actually entitled to. I’ve spent years covering commercial property in the UK, and the question I hear most often is simple: “What happens if my landlord tries to kick me out or won’t let me renew?” The answer depends on something called tenant indemnity, and most people don’t realise how much leverage they actually have.
Commercial leases in the UK are far less regulated than residential tenancies. That’s not necessarily bad news — it means you have room to negotiate — but it also means the specific terms you agree to upfront will determine almost everything about your rights later. Miss a clause about break conditions or repair obligations, and you could be locked into a lease you can’t get out of, or hit with a bill you never saw coming. Here’s what you actually need to know.
What Tenant Indemnity Actually Means for Your Business
The core of tenant indemnity is the Landlord and Tenant Act 1954, which gives most commercial tenants the right to stay in their property when the lease ends and apply for a new one. This is called security of tenure. It’s the single most important protection you have — and it can be taken away from you if you’re not careful.
If your lease is “contracted out” of the 1954 Act, you lose that right. That means when the lease ends, the landlord can ask you to leave without needing a reason. You must receive formal warnings and sign a special agreement for this to be valid — never skip reading those documents. What I’d do: if a landlord proposes contracting out, ask why. If they can’t give a solid business reason, push back. You’re giving up a major protection, and you should only do it when the trade-off is genuinely worth it.
Why This Matters More Than You Think
Here’s the scenario that plays out more often than people realise. You’ve spent two years fitting out a café kitchen, building a customer base, and getting the local community to know your name. Then your lease ends, and the landlord decides to redevelop the building. Under the 1954 Act, redevelopment is one of the valid grounds a landlord can use to oppose renewal. But they have to prove it — and you have the right to challenge them in court if the grounds aren’t genuine.
Without security of tenure, you’d have no grounds to challenge at all. That’s the difference between having a fighting chance and being told to pack up. The self-contained office lease guide covers more on what to look for in these situations.
There’s also a demographic angle worth noting. Businesses in prime London locations paying the average £183 per square foot in rent are often dealing with institutional landlords who have legal teams on retainer. Smaller businesses in regional cities may face less aggressive landlords but also have less leverage. Either way, knowing your rights levels the playing field.
Where People Go Wrong With Commercial Leases
I’ve seen the same patterns repeat across dozens of lease disputes. Here are the mistakes that cost businesses the most.
Signing a Contracted-Out Lease Without Understanding the Trade-Off
Contracting out of the 1954 Act is common — landlords prefer it because it gives them flexibility. But many tenants sign without realising what they’re giving up. If you’re contracted out, you have no automatic right to renew. When the lease ends, you leave. Period. The trade-off is that you might get a lower rent or a shorter commitment, but you need to weigh that against the risk of losing your location. If you’re unsure, speaking with a tenant landlord lawyer before signing can save you from a costly mistake.
Ignoring the Break Clause Conditions
Break clauses let you or the landlord end the lease early, but they come with conditions. Typical requirements include giving vacant possession, complying with all repair covenants, and paying every sum due. Miss one condition — even a minor repair — and the break might be invalid. I’ve seen tenants lose their break date because they left a few boxes in the corner, which technically meant they hadn’t given vacant possession. Read the break clause like your business depends on it, because it does.
Accepting Broad Repair Obligations Without a Schedule of Condition
Full repairing and insuring (FRI) leases are the most common type of commercial lease in the UK. They make you responsible for all repairs, including structural elements and the roof. If you sign an FRI lease without a schedule of condition — a document that records the property’s state at the start — you could end up paying for pre-existing damage. A professional survey before signing is not optional; it’s essential. The building insurance guide for commercial tenants explains how these obligations interact with your insurance requirements.
Overlooking the 2025 Right to Manage Changes
Effective March 3, 2025, the threshold for Right to Manage (RTM) eligibility in mixed-use buildings increased from 25% to 50% non-residential floorspace. That means if your business occupies space in a building with up to 50% commercial use, you may now qualify for RTM — giving you and other tenants control over management functions. This is a significant shift that most tenants don’t know about yet. If you’re in a mixed-use building, check whether you now qualify.

Get a Schedule of Condition Before You Sign
This is the single most effective way to limit your repair liability. A schedule of condition is a photographic and written record of the property’s state at the start of the lease. It sets a baseline: you’re only responsible for maintaining the property to that standard, not improving it. Negotiate for a clause that says “keep in repair” rather than “put and keep in repair” — the latter makes you responsible for fixing pre-existing issues. A property lawyer can help you draft this language into the lease.
Negotiate Rent Review Caps and Longer Intervals
Most commercial leases allow rent reviews every three to five years, often with upward-only provisions. That means your rent can go up but never down, even if the market drops. Negotiate for a cap on increases — say, a maximum of 10% per review — and try to extend the review period to five years instead of three. If the landlord insists on upward-only, ask for a reciprocal clause that allows you to trigger a review if market rents fall. It’s a fair ask and shows you understand the terms.
Understand Your Dilapidations Exposure
At the end of the lease, the landlord can claim for dilapidations — the cost of repairing damage beyond normal wear and tear. Without a schedule of condition, those claims can be excessive. Some landlords try to claim for “betterment,” meaning they want you to pay for improvements that go beyond the original state of the property. A cap on dilapidations liability and an exclusion for fair wear and tear are both negotiable. If you’re facing a dilapidations claim, a business lawyer can review whether the claim is valid.
Check Whether You Now Qualify for Right to Manage
If you’re in a mixed-use building with up to 50% commercial space, the 2025 legal change may give you and other tenants the right to take over management of the building. This is a forward-looking opportunity that most tenants haven’t considered. It means you could control service charges, maintenance decisions, and even who gets to lease vacant units. Talk to other tenants in your building and consider forming a RTM company if the numbers work. The short-term commercial leases guide covers related considerations for flexible arrangements.
