Around 94.9% of UK businesses lease their commercial premises, which means almost every retailer you see in a shopping centre is working under a lease agreement of some kind. That statistic alone tells you how central leasing is to British commerce, yet the most important lease in any mall — the anchor tenant’s — is the one most people misunderstand.
I’ve spent years watching landlords and tenants negotiate these agreements, and the gap between what people assume and what actually happens is wider than you’d think. A single anchor choice influences your property’s performance trajectory for the next decade, so getting the lease terms right matters far more than most business owners realise. Here’s what you actually need to know.
If you’re currently reviewing a lease or preparing to negotiate, you might find it useful to read through what landlords won’t tell you about commercial rent negotiation — it covers the tactics that rarely make it into the official guidance. And if you’re looking for a practical way to get professional eyes on your specific lease terms before you sign, speaking with a tenant landlord lawyer can save you from costly mistakes that aren’t obvious on first reading.
What an anchor lease agreement actually is
The most important thing to understand is that an anchor lease isn’t just a bigger version of a standard shop lease. It’s a fundamentally different economic arrangement. The anchor takes a large, often purpose-built footprint on a long lease — frequently fifteen to twenty-five years, sometimes with options that stretch further. A small specialty tenant takes a few hundred square metres on a five or ten year term. The anchor pays a fraction of the rent per square metre because the landlord is buying something: foot traffic, credibility, and the leasing velocity that follows.
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. The same logic explains why some anchors pay close to zero base rent, or take an inducement to sign at all. What I’d do if I were advising a landlord is never lose sight of that trade-off — the rent gap is the investment, and the foot traffic is the return.

Why the economics of anchor leases matter for your business
The base rent gap isn’t just an accounting curiosity — it determines who pays what, who takes what risk, and how the whole centre performs. When selected and structured strategically, an anchor becomes more than a tenant. It becomes a catalyst that can drive accelerated leasing velocity for complementary spaces, stronger achieved rents through co-tenancy synergies, and enhanced tenant retention in anchor-adjacent locations.
Different anchor types produce different patterns. Grocery anchors typically strengthen quick-service restaurants, services, and convenience retail. Off-price anchors typically strengthen beauty, value apparel, and home goods. Medical anchors typically strengthen wellness, childcare, and healthy dining. If you’re a landlord planning your tenant mix, matching the anchor type to the right complementary tenants is where the real value lives.
One pattern I notice repeatedly is that landlords underestimate how much the anchor’s visit frequency shapes the rest of the centre. A grocery anchor drives weekly trips; a department store drives monthly trips; a medical anchor drives scheduled appointments. Each pattern demands a different tenant mix and a different approach to common area maintenance. Maximising value for money on landlord service charges covers how those costs get allocated in practice.
If you’re a tenant trying to understand how service charges might affect your bottom line, a financial advisor can help you model the full cost of occupancy before you commit.
Where people get anchor lease negotiations wrong
Treating the base rent gap as a discount rather than an investment
Many landlords see the low base rent as a concession they’re forced to make, rather than a strategic investment. That mindset leads to poor lease structures. The base rent gap buys something specific: foot traffic, credibility, and leasing velocity. If the anchor isn’t delivering those things, the rent isn’t justified. If it is, the landlord should be capturing some of that value through percentage rent clauses.
A simplified percentage rent clause has three numbers: the base rent, the percentage rate, and the breakpoint. 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. 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.
What I’d do is always include a percentage rent clause with a natural breakpoint. It aligns incentives and ensures the landlord shares in the upside without penalising the anchor during lean years.
Ignoring CAM allocation until it’s too late
Common area maintenance 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. 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 smaller tenant, this matters because you end up shouldering a disproportionate share of the variable costs. A guide to tenant service charge documentation walks through what to look for in those service charge schedules.
Overlooking the 2025 Right to Manage threshold change
Effective March 3, 2025, the threshold for Right to Manage eligibility in mixed-use buildings increased from 25% to 50% non-residential floorspace. That means mixed-use buildings with up to 50% commercial space now qualify for Right to Manage provisions. If your anchor lease is in a mixed-use building, this change affects who controls the management of the common parts. It’s a relatively recent development that many lease negotiators haven’t fully absorbed yet.
Drafting exclusivity clauses too broadly
Rather than granting broad food exclusivity to a grocer, consider protecting “full-service supermarket operations exceeding 20,000 square feet.” Broad exclusivity clauses can prevent you from leasing to emerging retail formats that don’t actually compete with the anchor. Define protected uses specifically rather than broadly, consider time-limited or performance-based exclusivity, and preserve flexibility for emerging categories and formats.

Negotiate the financial structure with percentage rent and CAM caps
Start with the base rent, but don’t stop there. The financial structure should include a percentage rent clause with a natural breakpoint, a CAM cap or fixed contribution for the anchor, and performance-based adjustments tied to property success metrics. The natural breakpoint formula — base rent divided by the percentage rate — ensures percentage rent kicks in only after the anchor has covered its base through sales. That’s fair for both sides.
For the CAM allocation, negotiate a fixed contribution or a cap that limits the anchor’s exposure to variable cost increases. The specialty tenants will absorb the remainder, but that’s the standard trade-off in anchor economics. If you’re a landlord, make sure the CAM provisions are clear in the service charge documentation so there’s no ambiguity later.
Build in data-sharing and marketing collaboration
One often-overlooked opportunity in anchor negotiations is establishing data exchange agreements. Consider requesting aggregated traffic patterns to inform property decisions, general performance indicators to track the health of the partnership, and customer insight sharing from loyalty programs. In exchange, properties can offer property-wide performance metrics, collaborative marketing opportunities, and priority consideration in property improvements.
Marketing collaboration that amplifies both brands and event coordination that drives centre-wide traffic should be written into the lease, not left to goodwill. These partnership elements turn a transactional landlord-tenant relationship into a strategic one.
Plan your leasing sequence around the anchor
The order in which you lease the remaining space matters. Phase 1 should focus on natural complements: for a grocery anchor, that means services, QSR, and daily needs retailers. Phase 2 moves to experience enhancement: differentiated dining options, lifestyle and wellness concepts, and regional or specialty retailers. Phase 3 brings in stability anchors: professional and medical services, education and enrichment, and financial services.
This sequencing maximises the anchor’s traffic-generation value. If you lease the wrong tenant types too early, you can undermine the co-tenancy synergies that make the centre work. How to negotiate a lease buyout for your business space covers what to do if you need to restructure an existing arrangement.
Include adaptation clauses for evolving retail formats
Retail changes fast. An anchor that works today might need a different format in five years. Adaptation clauses allow the anchor to evolve its store format, integrate omnichannel strategies, and adjust its footprint without triggering a full lease renegotiation. Periodic review mechanisms — say every five years — ensure the lease terms remain aligned with the market reality.
What I’d do is include a clause that requires the anchor to maintain its commitment to omnichannel strategies that drive both digital and physical engagement. An anchor that invests in its online presence still drives foot traffic through click-and-collect and returns processing, so the landlord benefits from that investment too.

The anchor lease is the single most important document in any shopping centre, and the economics behind it are more strategic than most people realise. The base rent gap, the percentage rent structure, the CAM allocation, and the exclusivity clauses all work together to determine whether the centre thrives or struggles. My advice is to approach every anchor negotiation as a long-term partnership, not a one-off transaction. Build in data-sharing, adaptation clauses, and periodic reviews, and you’ll have a lease that works for both sides for the full term.
