Most commercial leases in the UK lock tenants into costs that go far beyond the monthly rent figure. The typical rent deposit alone sits at three to six months of rent, and that’s before you count service charges, insurance contributions, business rates, and the end-of-lease bill for dilapidations. What many business owners don’t realise is that nearly every term in a commercial lease can be pushed back on — but only if you know which ones to challenge and when.

Landlords start from a template that heavily favours them. The RICS Code for Leasing Business Premises sets a professional benchmark for heads of terms, and tenants can legitimately cite it during negotiation. But most don’t. The result is that leases get signed with costly clauses that the landlord never had to defend. Here’s what you actually need to know.
What This Article Covers — and What the Landlord Won’t Tell You
Most commercial leases in the UK are what’s known as a Full Repairing and Insuring lease, or FRI for short. That means you, the tenant, are responsible for all repairs and maintenance, plus the cost of the landlord’s building insurance. What the landlord won’t volunteer is how much that can cost at the end of the lease if you haven’t documented the condition of the property from day one.
What I tend to notice is that tenants who bring a surveyor in before signing almost always end up with a better repair clause. The cost of a survey is small compared to what you can be billed for at exit. If you’re looking at the bigger picture of renting a commercial space for a specific use, the same due diligence applies — don’t skip the condition check.
The Full Cost of a Commercial Lease: What the Monthly Rent Doesn’t Cover
The headline rent is only part of the picture. The table below shows the full range of costs a tenant typically pays over the life of a lease. Some are one-off, some are annual, and a few only show up at the very end.

| Cost | Typical amount | When it’s paid |
|---|---|---|
| Base rent | Negotiated per sq ft | Monthly or quarterly |
| Rent deposit | 3–6 months’ rent | At signing (refundable) |
| Service charge | Varies by building | Annual or quarterly |
| Building insurance | Varies | Via service charge or separately |
| Business rates | Based on rateable value | Monthly to local council |
| SDLT on lease | Based on net present value of rent | Within 14 days of completion |
| Legal fees | £1,000–£3,000+ | During negotiation |
| Surveyor fees | £500–£2,000+ | Before signing |
| Fit-out costs | Varies by space | Before move-in |
| Dilapidations at exit | Varies (can be tens of thousands) | At lease end |
Take a rent of £30,000 per year on a ten-year FRI lease. If the rent review is upward-only and the market moves — or even if it doesn’t — your rent never drops. Over ten years, that single clause can cost you thousands more than a capped or fixed-increase review. The SDLT on leases is calculated on the net present value of the total rent, so a higher rent means a higher tax bill from the start.
If you’re unsure how to structure your negotiation budget, talking through the numbers with a business law specialist can help you see which costs are worth fighting over and which are industry standard.
Four Traps That Cost Tenants the Most Money
Signing without a schedule of condition
Under an FRI lease, you take on full responsibility for repairs — including the structure. If you don’t have a schedule of condition that records the property’s state at the start, you have no way to prove that cracks, leaks, or worn-out fixtures were there before you moved in. At the end of the lease, the landlord can claim for all of it. The fix is straightforward: commission a surveyor to produce a schedule of condition before you sign, and attach it to the lease. It costs a few hundred pounds and can save you tens of thousands.
A break clause you can’t actually use
Break clauses sound like a safety net, but landlords often load them with conditions that are easy to fail. “Material compliance with all covenants” is a common one. If the landlord argues you didn’t keep the property in good repair, or that you breached a minor covenant, your break notice can be invalid. The solution is to negotiate conditions that are simple and objective: pay the rent up to the break date, give proper notice in writing, and provide vacant possession. Nothing vague.
A use clause that’s too narrow for your business
If the lease says “coffee shop” and you later want to add sandwiches or open in the evening, you’ll need the landlord’s consent. They can refuse, or charge a fee for the change. What I’d do is negotiate a use clause that covers your current activity plus a reasonable range of similar uses. Future-proofing it now avoids a costly renegotiation later.
Service charges with no cap or transparency
Commercial service charges are not capped by law. The landlord can include management fees, major works, and even improvements if the lease allows. Without a cap, you’re exposed to whatever the landlord decides to spend. Push for a clear list of what’s included and excluded, an annual budget and reconciliation, and a cap on annual increases. Some tenants also negotiate an exclusion for major capital works that aren’t repairs.
How to Negotiate a Commercial Lease That Actually Works for You
Start with heads of terms, not the lease draft
The heads of terms document is the non-binding summary of your deal. It should cover rent, lease length, break options, rent-free period, service charge cap, permitted use, repair responsibilities, and any incentives. The RICS Code for Leasing Business Premises recommends that both sides agree these terms before the lawyers start drafting. If you agree the deal in principle first, you have more leverage when the formal lease appears with clauses that don’t match what you discussed.
Three clauses to spend your negotiation budget on
You can’t win every point, so focus on the three that cost the most if they go wrong. First, the repair clause — make sure it’s backed by a schedule of condition and excludes structural issues that predate your tenancy. Second, the rent review clause — negotiate a cap, change the method to fixed increases, or at least limit the frequency to every five years instead of three. Third, the break clause — keep the conditions minimal and achievable. If you get these three right, the rest is detail.
When to bring in a solicitor and a surveyor
A solicitor reviews the lease, negotiates changes, and handles the legal completion. A surveyor assesses the building’s condition and produces the schedule of condition. Both are recommended for any lease over three years. The solicitor’s fee typically runs £1,000–£3,000, and a survey costs £500–£2,000. Compared to the cost of a single dilapidations claim or a failed break clause, that’s cheap insurance. If you’re working with a tight budget, a real estate lawyer can review the key clauses without the full-service cost.
What’s changing that affects your lease
Several regulatory changes are already in motion. Since April 2023, letting commercial premises below EPC band E has been prohibited. The Law Commission is reviewing the Landlord and Tenant Act 1954, with a second technical consultation open until 16 September 2026. Business rates are due for revaluation in April 2026, which will reset rateable values based on recent market evidence. And the Terrorism (Protection of Premises) Act 2025 — known as Martyn’s Law — received Royal Assent in April 2025 and will impose new security obligations on certain premises. These changes affect your total cost of occupation and your compliance obligations, so factor them into your lease planning now rather than dealing with them later.

The Lease Is a Negotiation — Treat It Like One
The single biggest mistake tenants make is treating the first draft of a lease as a take-it-or-leave-it document. It isn’t. Commercial leases are negotiated contracts, and the landlord expects you to push back on some terms. The ones that cost you the most — repair obligations, rent review mechanisms, break conditions, and service charge caps — are also the ones where landlords typically have the most room to move. The regulatory landscape is shifting too, with EPC rules, the Law Commission review, and business rates revaluation all adding new layers to the cost of occupation. The time to understand those costs is before you sign, not after.
