Nearly 95% of UK businesses lease their commercial premises rather than own them, which means almost every company you deal with is working under a lease of some kind. That figure from conveyancing data on UK businesses tells you something important: leasing is the default, not the exception. I’ve spent years watching business owners sign leases without fully understanding the economics behind them, and the one arrangement that causes the most confusion is the anchor tenant lease.
An anchor tenant — the supermarket, department store, or big-box retailer that takes up a third or more of a shopping centre — pays dramatically less per square metre than the small boutique next door. A small fashion unit near the food court can pay several times the rate per square metre that the anchor pays, despite renting a fraction of the space. If you’re a smaller business negotiating a lease in a centre with an anchor, or if you’re considering becoming an anchor yourself, the economics work very differently from what most people expect. Here’s what you actually need to know.
Before you sign anything, it’s worth understanding how commercial space leasing works in practice — the hidden costs and negotiation points that don’t appear on the first page of a lease. And if you’re dealing with a complex lease negotiation, speaking to a tenant landlord lawyer early can save you from terms that look reasonable but cost you dearly later.
How anchor tenant lease economics actually work
The core logic is simple but counterintuitive. An anchor tenant brings customers through the door, which makes every other unit in the centre more valuable. The landlord therefore offers the anchor a low rent per square metre as an incentive to sign a long lease — typically fifteen to twenty-five years, sometimes with options that stretch further. The small specialty tenant, by contrast, takes a few hundred square metres on a five or ten year term and pays a much higher rate because they benefit from the foot traffic the anchor generates.
Consider an illustrative centre. The anchor occupies 12,000 square metres and pays a base rent of 80 currency units per square metre per year. A typical inline fashion unit occupies 200 square metres and pays 600 units per square metre. The anchor pays 960,000 a year for a third of the centre; the inline unit pays 120,000 for a sliver of it. On a per-square-metre basis the small tenant pays roughly seven and a half times more. That gap isn’t unfair — it reflects the value the anchor brings. But if you’re a small tenant, you need to understand that you’re subsidising the anchor’s low rent through your own higher rate.
What I’d do as a small tenant is ask the landlord directly what the anchor’s base rent is per square metre. They won’t tell you the exact figure, but the question itself signals that you understand the economics. It also opens a conversation about whether your rent reflects the foot traffic you actually receive, or whether you’re paying a premium for a benefit that doesn’t fully reach your unit.
Why the base rent gap matters for your business
The base rent gap isn’t just an academic curiosity — it directly affects your bottom line. If you’re a small retailer paying 600 units per square metre while the anchor pays 80, your rent is eating a much larger share of your revenue. That matters because average office rents in the UK have reached £183 per square foot, and retail rents in prime locations can be significantly higher. Every pound you spend on rent is a pound you can’t reinvest in stock, staff, or marketing.
The gap also creates a behavioural pattern I see repeatedly: small tenants assume their rent is fair because it’s what the market charges, without realising that the market is distorted by the anchor’s preferential terms. A small fashion unit near the food court can pay several times the rate per square metre that the anchor pays, despite renting a fraction of the space. That’s not a bug — it’s a feature of how commercial leasing works. But it’s a feature you can negotiate around if you understand it.
Here’s a scenario: imagine you run a 200-square-metre clothing boutique in a shopping centre where the anchor supermarket pays 80 units per square metre. You’re paying 600. Your annual rent is £120,000. If you could negotiate down to even 500 units per square metre, you’d save £20,000 a year — enough to hire a part-time assistant or fund a marketing campaign. The anchor’s low rent isn’t your enemy; it’s your reference point.
What I’d do is use the anchor’s presence as leverage. If the anchor generates foot traffic that benefits your business, acknowledge that value — but also point out that your rent should reflect the actual benefit, not a blanket premium. Ask for a rent review that ties your rate to a percentage of the anchor’s rate, or request a turnover-linked rent structure that aligns your costs with your revenue. More on that in the main guide below.
If you’re negotiating a lease in a centre with an anchor, it’s worth reading about how independent retailers handle high rents — the strategies that work and the ones that don’t.
Where businesses get anchor lease terms wrong
I’ve seen three mistakes repeat themselves across dozens of lease negotiations. Each one costs real money.
Ignoring the CAM allocation trap
Common area maintenance charges — CAM for short — cover the cost of cleaning, lighting, security, and maintaining shared spaces like corridors, lifts, and car parks. CAM is normally allocated by floor area, so each tenant pays a pro rata share based on the space it occupies relative to the leasable total. The anchor pays little base rent per square metre, but because CAM follows area, it carries a large slice of the shared running costs simply by being large.
In practice, anchor leases frequently negotiate CAM caps, exclusions, or fixed contributions, precisely because a strict pro rata share would hand the anchor a bill out of proportion to the rent it pays. A common pattern is for the anchor to pay a capped or fixed CAM amount while the specialty tenants absorb the remainder of the variable cost. If you’re a small tenant, you could end up paying a disproportionate share of the centre’s running costs because the anchor has capped its contribution.
What I’d do is ask for a breakdown of CAM charges and check whether the anchor has a cap. If they do, request a similar cap for your own lease, or ask for CAM to be allocated based on something other than floor area — for example, a fixed amount per unit or a percentage of turnover. A tenant landlord lawyer can review your service charge provisions and flag any allocation that looks unfair.
Overlooking co-tenancy protections
Co-tenancy clauses typically let the small tenant reduce rent, switch to a percentage-only arrangement, or in some cases terminate, if a named anchor goes dark or if occupancy across the centre falls below an agreed threshold. These clauses exist precisely because the small tenant’s business depends on the anchor’s presence. If the anchor leaves, foot traffic drops, and your rent should drop with it.
The mistake I see most often is tenants not asking for a co-tenancy clause at all, or accepting one that only triggers if the anchor closes permanently rather than if it simply reduces its hours or changes its format. A good co-tenancy clause should cover partial closures, changes of use, and sustained reductions in foot traffic — not just a full shutdown.
Misunderstanding percentage rent mechanics
Percentage rent — where the tenant pays a low fixed base plus an additional percentage of sales above an agreed threshold — is common in anchor leases but increasingly appears in smaller tenant leases too. The mechanics are straightforward but easy to get wrong. A simplified percentage rent clause has three numbers: the base rent, the percentage rate, and the breakpoint. The percentage rate is the share of qualifying sales the tenant pays above the breakpoint, often a single-digit percentage that varies by tenant type.
A natural breakpoint is set so the base rent equals the percentage rate applied to it, meaning percentage rent begins exactly where the tenant has earned back its base in sales terms. Work the illustrative anchor through it. Say the anchor pays 960,000 in base rent and the lease sets a percentage rate of 2 percent. The natural breakpoint is the base divided by the rate: 960,000 divided by 0.02, which is 48 million in annual sales. Below 48 million the anchor pays only its base. If the anchor turns over 60 million, it pays the base plus 2 percent of the 12 million above the breakpoint, an extra 240,000, for a total of 1.2 million.
The mistake is accepting a breakpoint that’s too low, which means you start paying percentage rent before your business has covered its base costs. Always calculate the natural breakpoint yourself and negotiate for a breakpoint that gives you room to grow before the landlord shares in your upside.

How to negotiate better anchor lease terms: a practical guide

Whether you’re the anchor tenant or a smaller business in an anchor-led centre, the same principles apply. Here’s how to approach each key term.
Negotiate your rent review basis
Rent reviews determine how your rent changes over the lease term. The most common basis is market value, but many leases include upward-only provisions, meaning your rent can only go up. That’s a risk if the market rises sharply. Negotiate for a cap on increases — for example, no more than 5% per review — or remove the upward-only provision entirely. Longer review periods, say every five years instead of every three, also reduce the frequency of increases.
If you’re an anchor tenant, you have more leverage to negotiate a turnover-linked rent structure. Leases are increasingly leaning towards mechanisms that align with the tenant’s operational performance, as noted in recent commercial lease trend analysis. A turnover-linked rent means your base rent stays low, and the landlord shares in your success only when you’re doing well. That’s a fairer arrangement for both parties.
Secure a schedule of condition
Under a Full Repairing and Insuring (FRI) lease, you assume responsibility for all repairs including structural elements, roof maintenance, and external decorations. That means you inherit responsibility for pre-existing issues unless you document them. A schedule of condition — a photographic and written record of the property’s state at the start of the lease — limits your repair obligation to maintaining that standard. Without it, you could be liable for fixing decades of deferred maintenance.
Professional surveys identifying existing defects become essential. A surveyor will flag cracks, leaks, and structural issues that you’d otherwise be on the hook for. The cost of a survey is a fraction of what you’d pay for an unexpected roof replacement.
Understand your break clause conditions
Break clauses provide crucial flexibility, allowing tenants to terminate leases before expiry. But exercising break rights requires strict compliance with notice periods and conditions, with even minor procedural errors potentially invalidating termination attempts. Typical break conditions include vacant possession requirements, compliance with repair covenants, and payment of all sums due.
What I’d do is treat your break clause like a flight departure time — you need to be at the gate early with all your paperwork in order. Set a calendar reminder six months before the break date, and work through each condition with a solicitor. A single missed payment or an unreturned key can cost you years of rent.
- 1Review your break clause conditionsCheck the notice period, vacant possession requirement, repair obligations, and payment conditions. Note the exact date by which you must give notice.
- 2Complete all repairs before the break dateMost break clauses require compliance with repair covenants. Schedule a professional survey six months before the break to identify any outstanding work.
- 3Pay all sums due in fullEven a small outstanding balance can invalidate your break. Request a final statement from the landlord and pay everything — including service charges — before the break date.
- 4Give notice in writing by the deadlineUse recorded delivery or email with read receipt. Confirm receipt with the landlord’s solicitor. Keep copies of everything.
Plan for 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 buildings with up to 50% commercial space now qualify for RTM provisions, which give tenants the right to take over management of the building. If you’re in a mixed-use building with significant commercial space, this change could give you more control over service charges and maintenance decisions.
This is an emerging angle that most tenants haven’t considered yet. If your building qualifies, you and other tenants could form an RTM company and take over management from the landlord. That’s a significant shift in power dynamics, and it’s worth discussing with a solicitor who specialises in commercial property law.

Your next move on anchor lease terms
The anchor tenant lease model isn’t going anywhere — it’s the economic engine that makes shopping centres and mixed-use developments viable. But understanding how the numbers work gives you leverage whether you’re the anchor or the small tenant next door. Start by reviewing your current lease for CAM allocation, co-tenancy protections, and break clause conditions. If any of those terms are missing or unfavourable, you have a clear negotiation point for your next renewal.
